From all-round academic master to chief scientist - Chapter 229 The Spark that Starts a Prairie Fire

Several academicians present are experts in machinery. As long as they are given parts and materials, they can build a car completely by themselves.

So when Lin Xiao showed them the internal structure of the encoder, they quickly realized what a perfect structure it was.

In other words, there is a brand new encoder structure here.

If the original encoder looks like a single-axis motor inside, Lin Xiao’s encoder looks like a four-cylinder engine inside.

At the same time, it is these “four cylinders” that enable this encoder to achieve an eightfold improvement in the original accuracy.

In the first half of the last century, encoders were born. At that time, encoders were basically mechanical encoders. Later, photoelectric technology gradually developed and expanded, so encoders embarked on the road of optical encoders. Optical encoders And because it is accurate enough, it has become mainstream.

Therefore, the current optical encoder mainly studies how to divide the displacement of one millimeter into more pulse signals, which places huge demands on the sensor.

However, Lin Xiao’s structure does not place its hopes on the advantages of optical sensors, but combines optics and mechanics to optimize accuracy.

This can definitely be called a work of genius. Even in the eyes of these academicians, Lin Xiao has created a new field of encoders.

Perhaps this new field can be called optical mechanical encoders.

“How did you come up with this structure? Why didn’t I think of it before?” Academician Tan couldn’t help but said.

Lin Xiao smiled and said: “It’s just a spatial imagination, and then I thought about it and I came up with it.”

Several academicians curled their lips.

When it comes to spatial imagination, it’s as if they are not strong. People who study their field don’t have strong spatial imagination.

The key is to see if you can capture those occasional flashes of inspiration.

The young man in front of him has undoubtedly achieved this.

Thinking of this, they felt amazed in their hearts.

Not only is he such a genius in theoretical research in mathematics and physics, but now he actually shows such talent in machinery. Are there really all-rounders in the world?

Suddenly, another academician Wang raised a question: “But, Lin Xiao, haven’t you considered implementing a ten-point or twelve-point structure? Why did you only come up with an eight-point structure?”

Hearing this, Lin Xiao smiled and said: “Of course I have considered this issue, but in the end I used mathematics to prove that the eight-point structure is the most suitable. If more points are made, it will eventually lead to more errors in the process. , and it will also have a greater impact on our production, and the eight-point structure is the easiest to achieve mass production.”

“Prove it directly with mathematics?” Several academicians expressed doubts.

Lin Xiao smiled, then found a piece of paper from the side, and then found a pen, and then began to establish a three-dimensional rectangular coordinate system on it, then pointed out points one by one on it, and finally wrote mathematical formulas.

Of course he had thought about a higher score structure before, such as sixteen points or even thirty-two points.

But obviously, the structure cannot be divided infinitely. At first, he just thought about it in his mind, but his strong number sense told him that none of this was true, and only eight points was the most suitable.

Of course, in order to let these academicians understand it better, he would directly prove it on the spot.

Soon, using two pieces of paper, he completed the solution to the limit value of an equation.

“So we can easily see that when x is equal to 4, the value of y is the smallest, so the error at this time is the smallest, and when x is equal to other values, y is not equal to 0.”

Seeing how Lin Xiaoxin easily transformed their actual mechanical problem into a mathematical proof process, several academicians looked at each other and felt a sense of shock.

In the end, they shook their heads and said, forget it, don’t compete with young people, they are just a group of middle-aged and elderly guys.

You can’t just say “Don’t bully the middle-aged and poor” or “Don’t bully the old and poor” and then decades later say “The dead are the most important”, right?

It’s better to serve your old age.

Also, just now they thought that this new encoder should be called an optical mechanical encoder, but now it seems that there is no change in the structure of this encoder in the future. Basically it can only be an eight-point structure.

Therefore, this new encoder can be called a Lin encoder, or this structure can be called a Lin structure, because it only has this look and cannot be changed.

Seeing several academicians like this, Lin Xiao smiled slightly and asked, “Do you have any questions?”

Several academicians waved their hands: “No problem.”

Lin Xiao nodded, then his eyes became serious and he said, “That’s good, then, fellow academicians, I have one more thing to ask of you now.”

The academicians were stunned and said, “You said that.”

Lin Xiao said: “Everyone should know the importance of this structure to the development of encoders.”

“certainly.”

“I must know.”

the academicians said.

The encoder accuracy is directly reduced by one-eighth through mechanical methods. Even if the gap between Chinese encoders and foreign encoders is large, it will not be less than one-eighth. Therefore, with this new technology, the future of domestic servo motors will Development is extremely important, enough to allow them to directly keep pace with the world.

Speaking of this, Academician Tan immediately asked: “By the way, Professor Lin, you should have applied for this patent, right? Don’t let others snatch it away.”

This kind of structural patent can be identified by top mechanical experts at a glance. This is also the disadvantage of this kind of structural technology. Therefore, if you don’t apply for the patent first, it will definitely be registered by others in the end.

Lin Xiao smiled and said: “Academician Tan, just don’t worry. I will definitely not ignore this kind of problem. The relevant patents have been applied for, both domestically and abroad.”

Then he said: “So, now I have a proposal.”

“The validity period of patents is basically 20 years at home and abroad.”

“This structure can basically be used for 20 years, so I do not plan to license this patent to foreign countries.”

“In addition, I am willing to license this patent to relevant domestic manufacturers for free.”

“I hope that this patent can inspire major manufacturers in my country to invest in this, so that our encoders in China can catch up with foreign countries, and then drive the development of other aspects!”

“All academicians should be familiar with those qualified manufacturers, and I hope all academicians can pass this news on to them.”

Lin Xiao’s eyes were very serious.

He had thought carefully about this plan before and made a decision.

Because of the development of China’s basic industrial technology, some energy needs to be invested in it to promote the development of the entire industry.

He cannot push it alone and can only make efforts in key areas. This requires the entire Chinese industry to promote it. One person’s efforts will not be as good as the efforts of everyone.

Domestic industrial technology development is stagnant and unable to keep up with foreign countries, precisely because of the lack of driving force.

But there is nothing we can do about the lack of motivation.

Domestic scientific research potential in this kind of industrial technology is not inferior to that of foreign countries. For example, in high-end machine tools, if we are really willing to put in some effort, it is not impossible to develop it.

But the current situation is that this kind of “making more efforts” has not happened. This is also because the country has been suppressed by foreign countries.

For example, in machine tools, if domestic companies spend a lot of effort to make breakthroughs in machine tool technology, foreign companies will immediately reduce the price of related technologies for domestic sales. Because of the concepts of “foreign quality is better” and “foreign technology is more advanced” , relevant domestic purchasers will give up purchasing domestic technology and choose to purchase foreign technology.

Therefore, the company that originally spent a lot of effort to achieve a breakthrough in this technology may go bankrupt because the investment is not proportional to the return. So other companies with this intention saw that other companies were so miserable, so they also I will give up this idea and settle down with peace of mind.

When domestic companies are in bad shape, the salary levels of technical personnel are also “bad”, and naturally they have no intention to contribute to technological breakthroughs.

After all, this is a market economy.

This is also the sinister intention of foreign companies. Foreign countries have united to restrict the development of China.

This is why Lin Xiao is willing to license this technology to domestic manufacturers for free. You must know that with this technology, he can cooperate with some foreign companies. Maybe he can earn tens of millions or hundreds of millions every year just from the licensing fees.

But obviously, it was impossible for him to do such a thing.

Don’t say that he spent the country’s money to research this technology. Even if he spent his own money, he would not specifically license this technology to foreign companies and let them continue to make money from China.

The economy is circulating, so every time it comes, it means that what he earns is still domestic money.

And he licensed the technology to the country. Since his technology is only a change in the mechanical structure, it does not bring much improvement to the production cost, but it can effectively catch up with the advanced foreign technology. There is a huge hidden hidden in the middle. profit difference.

By then, when domestic companies see opportunities to make money, it is entirely possible that they will work hard to research on this. When the technology breaks through, they will make foreign money.

Domestic companies have made money. As long as they are not the kind of companies that have no future, they will always think about going further. Even if only two or three companies have this idea, it is meaningful.

In this way, the domestic basic industrial technology research environment has been slightly improved, and it will inevitably not become a spark that starts a prairie fire in the future.

This is what Lin Xiao wants to do.

When several academicians heard Lin Xiao’s decision, their eyes were already shocked.

Lin Xiao actually plans to share such an important technology with domestic manufacturers for free?

And his purpose is to stimulate domestic development?

“Professor Lin, are you sure?”

Academician Tan couldn’t help but ask.

“Of course.”

Lin Xiao said.

“There’s a lot of money to be made from this technology.”

Lin Xiao shook his head: “I spent the country’s money to develop this technology. This technology naturally belongs to the country. Even if I make money, it still belongs to the country.”

“But rather than using it to make money, I think this patent should play a more important role.”

Listening to Lin Xiao’s words, several academicians were finally convinced that he was serious.

Several older academicians, such as Academician Tan, who is almost 70 years old this year, came from that difficult era. People at that time still had faith. How is it like now?

But at this moment, he saw the brilliance of faith in Lin Xiao.

Beside the wrinkled eyes, the light seemed to waver slightly.

Then, he walked up and held Lin Xiao’s hand tightly, “Comrade Lin, you have worked hard. I will tell the domestic manufacturers about your request, and I will also thank you for your contribution on their behalf.”

Several other academicians were similarly moved and expressed their agreement.

At this time, they all had sincere admiration for the young man in front of them. Before, it was admiration for his talent, but now, it is respect for other spirits.

They couldn’t help but reflect on themselves. If it were them, could they make Lin Xiao’s decision?

Finally, they sighed softly. They suddenly felt that they did not have that confidence.

Lin Xiao smiled, and then said: “Okay, fellow academicians, it’s almost dinner time now, shall we go have a meal together? I’ll treat you.”

Hearing what Lin Xiao said, the academicians also smiled.

The atmosphere just now changed to relaxed and normal.

“good.”

“Professor Lin is treating me to a treat, I must go.”

“Are you leaving now?”

“let’s go.”

Then, they all tidied up and headed to the restaurant.

In the restaurant, the topics they talked about became more casual.

“Professor Lin, your incident has caused quite a big fuss recently? Is it really an American?”

Lin Xiao smiled and said, “If nothing else happens, basically yes.”

The call Guoan made to him was just the first call, and there were several more calls after that.

There are many ways to determine whether a message is true.

Embassies of various countries will more or less carry out some intelligence activities, so their ambassadors to Israel can learn about one aspect of things and naturally discover some clues.

In particular, the FBI’s trip to Israel requires the cooperation of multiple departments, such as the public security department.

So this news can easily be verified as true.

In this regard, Lin Xiao was also very happy that he did not go.

Of course, as he told Director Ma before, he wanted to win the award so that the country could better support him, but when the country directly spent billions to build a research institute for him, these awards were lost to him. attractive.

After all, pursuing the truth is what he wants.

After hearing Lin Xiao’s affirmation, several academicians started to curse.

“Those white-skinned guys are really determined to kill me. Sooner or later, I have to make them look good.”

Similarly, some people were concerned about Lin Xiao: “Professor Lin, public opinion seems not to be very good to you recently. Don’t be affected by those things on the Internet.”

Lin Xiao smiled: “Don’t worry, it won’t happen. What’s more, the country will also stand up for me.”

In such a matter, it is impossible for the country not to help him clear his name.

“That’s good.”

The academicians all nodded.

…

Hua Guo moved quickly to clear Lin Xiao’s name.

A few days later, the Ministry of Foreign Affairs formally raised the incident at a regular meeting.

[It has been verified that on the day that Chinese scientist Professor Lin Xiao planned to go to accept the Wolf Prize, FBI personnel went to the Israeli airport to wait. Considering that FBI personnel had repeatedly framed Chinese scientists, after communicating with Professor Lin Xiao , Professor Lin Xiao decided to refuse to accept the award.

At the same time, we hereby lodge a solemn protest. If such actions continue to pose a potential threat to our scientists, we will also take reciprocal measures. We hope that this will not be unforeseen! 】
