Chapter 227 National Security Warning!

"Phillip, you're here."

"Hey Philip."

…

When he arrived at his workplace, Philip Meng was welcomed by his colleagues and greeted them with a smile. His face was normal and there was no flaw in it.

Soon he came to his office. In fact, there were many computers here, and the staff were wearing headphones and working.

In fact, this office is the place used by the FBI for surveillance. Here, they can monitor the mobile phones of various targets, or monitor places where targets may appear.

Here, they seem to feel a sense of control over the world, because they can invade other people's privacy wantonly.

However, Philip Meng didn't like this feeling. Invading other people's privacy did not bring him any pleasure, but instead he felt a little guilty.

At first, he joined the FBI because he could do some work of arresting important wanted criminals. However, when he was later transferred to some power departments, they were able to enter ordinary people's homes at will, bully those ordinary people, and even accidentally killed some ordinary people. And they But he is not responsible for it at all, he just writes a report.

These things made him a little disgusted, and he even planned to resign. If he hadn't become an international fighter later, he would be willing to continue working.

Shaking his head, he stopped thinking about it and carried out his task honestly.

Time passed quickly, I finished my work in the morning and went to their restaurant for lunch at noon.

After finishing his meal and passing by his seat, he suddenly heard the person next to him mention "Israel".

Immediately, he raised his attention.

"I'm going on a business trip to Israel tomorrow. Let's go have a meal together tonight?"

"Okay."

“But the name of the city in Israel is really strange, Herzliya Pituya, have you heard of it?”

"No."

"All right……"

There were only a few words of dialogue that made him frown, and then he simply sat behind the person who said these words and continued to listen.

He didn't take the initiative to ask. In the FBI, if you don't have a good relationship, it is a "dangerous" thing to inquire about other people's missions, because it is likely to be suspected, especially since he is a Chinese.

But after that, he didn't get any other useful information, and there was no word "wolf".

Of course, at least he got some useful information. They really had a mission to go to Israel, and it might be related to this city called Herzliya Pituya.

After lunch, work continues.

He didn't get any useful information after that.

After get off work, he returned home as usual. After saying hello to his wife and daughter, he entered the study room, turned on his computer, and then went to the Amazon platform and logged in to an account.

This account is called [star-bookstore], which is the bookstore that sent him the book.

His account is the bookstore’s online store on the Amazon platform.

Then he went backstage and found the book "Weakness", then removed it from the shelves, and then re-listed a product called "Herzliya Pituya".

After doing all this, he quickly exited and deleted all kinds of data, including log files. After that, he let out a sigh of relief.

His mission was accomplished, I hope they can analyze some useful information.

Then, he walked out of the study and walked into the dining room.

"Dad, it's time to eat!"

When the daughter saw her father coming, she shouted.

Philip Meng walked over with a smile, picked up his daughter, kissed her forehead gently, and then said: "Oh, my little sweetheart is waiting impatiently, so hurry up and eat!"

"Um!"

His wife asked: "Why did you enter the study as soon as you came back today?"

Philip Meng smiled and said: "I bought a book today and went to the study room to read it for a while."

"So that's it." The wife nodded, without paying much attention, and said with a smile: "Then eat quickly, it's your favorite Chinese food."

…………

…

May 16th.

Although he is leaving for Israel tomorrow, Lin Xiao has already informed the Wolf Prize team of the relevant news, including the people accompanying him, his family, and some of his friends at Beijing University.

However, he still stayed in the laboratory and did not leave.

"Finally made."

Looking at a motor-like thing on the workbench in front of him, Lin Xiao let out a sigh of relief.

This is the encoder that he spent so long to build, and it took him a lot of effort. Of course, his kind of purely hand-made one is inherently very slow.

There are not many relatively precise things used in this encoder. He just needs to verify whether his structure can be successful. According to the configuration inside, the positioning accuracy of this encoder can only be maintained at 1 micron at most.

However, if the eight-point transmission structure he set up inside is used, the positioning accuracy should be controlled at 125 nanometers, which is one-eighth of 1 micron. Of course, considering the friction, the material is not absolutely rigid. There will be a certain amount of deformation when pulling, so the actual accuracy, according to Lin Xiao's calculations, is around 133 nanometers.

Therefore, if better accessories can be used in the future, this accuracy will be reduced again.

"Well, let's give it a try now."

With this thought in his mind, he found a servo motor, which he had originally bought just for today's test.

The specification accuracy of this servo motor is about 1 micron. Of course, Lin Xiao did not forget the actual accuracy test.

As for how to test the actual accuracy, it is obvious that the naked eye cannot tell the difference, nor can a microscope, because we do not have a scale accurate to the micron or even nanometer level.

Therefore, it is necessary to use a professional instrument called a laser interferometer for measurement. Let the servo motor send out a pulse. A pulse will cause it to move a minimum displacement, and then measure the wavelength level through the changes in the fringes formed by the laser interferometer. displacement to determine its positioning accuracy.

Soon, it was determined that the accuracy of this servo motor was indeed 1 micron.

Then he started to take out the encoder inside, and then replaced his own encoder.

Except for the different internal structure, the encoder he built is completely matched with the servo motor, so next, we just need to see if his new encoder can reduce the accuracy of the servo motor by one-eighth.

After tightening the last screw, Lin Xiao held the rather heavy servo motor and placed it next to the laser interferometer again.

After everything is ready, the measurement begins.

First, send a pulse to the servo motor on the computer to make its rotor rotate once.

Then, he immediately opened the software of the laser interferometer and took a look at the change in wavelength. Then based on this change, he began to calculate, and finally calculated the actual distance traveled by a pulse.

"137...Nano!"

Seeing this result, Lin Xiao's face suddenly showed a smile.

Perfect!

Although there was still a slight difference from his previous theoretical calculation, the difference was only a few nanometers, which was enough for him to ignore it.

This also shows that his encoder "eight-point" structure has been successfully verified.

This structure can obviously be used in various encoders. Not only the encoder he is building now, but also the accuracy of various other encoders can be directly reduced by nearly one-eighth like this. Regardless of whether it is in the future Servo motors used in photolithography machines, or servo motors that may be used in machine tools in the future, especially these two servo motors, both pay attention to accuracy. Why can Huaguo Machine Tools only make mid-to-low-end products?

First of all, it has a lot to do with high-precision encoders. The encoder first determines the accuracy, and then other auxiliary technologies. Therefore, as long as this structure is applied to the encoders of those machine tools, at least for domestic machine tools It is also an improvement.

Therefore, the eight-point structure is the best way that Lin Xiao can think of to bring huge improvement to China based on the current strength of China's basic industry.

In addition, after applying for a patent for this structure, earning patent licensing fees can also bring a lot of income.

But obviously, Lin Xiao does not intend to license this patent to foreign manufacturers, but only to domestic manufacturers, at least so that their domestic encoders can be ahead of foreign manufacturers.

Lin Xiao smiled slightly, and at this moment, the system's voice rang: "Congratulations to the host for designing a wonderful mechanical structure, which has greatly improved the accuracy that ordinary machinery can achieve. This time the physics award is 600 experience points, 400 material science experience points, 20 truth points, [Machine Overall Optimization Guidance*1].”

Hearing the voice of the system, Lin Xiao couldn't help but be stunned. Can he still get rewards from the system?

Looking at the rewards, there are a total of one thousand experience points, which is not bad. The problem he solved is the application of physics and materials knowledge, so rewarding him with physics experience and materials experience is within expectation.

But, why can't he be rewarded with 200 more points of physical experience?

He still has 200 experience points before he can upgrade his physics to level 5 and gain 0.6% brain development.

Unfortunately, the system said whatever it said, and there was nothing he could do about it.

Then, he turned his attention to this [Machine Overall Optimization Guidance].

He asked in his mind: "What is [Mechanical Overall Optimization Guidance]?"

System; “When the host uses [Mechanical Overall Optimization Guidance] and selects a mechanical instrument, it will be able to get guidance on overall optimization of the mechanical instrument. The guidance includes but is not limited to mechanical structure, mechanical power, energy scheme, For the optimization of key components and other aspects, the host can freely make choices based on these guidance. Note: If the host has its own ideas before optimizing the machinery, there is a chance that the host will receive guidance in this regard."

Lin Xiao's eyes suddenly lit up when he heard the effect of this reward.

What a good thing, it can actually guide him to directly optimize the overall optimization of a machine?

"Then can I use it on this servo motor?"

Lin Xiao started to think, but soon he slapped his head again.

It's just optimizing a servo motor, which is nonsense.

For such a good thing, the more important it is to optimize, the better. He can directly optimize the lithography machine.

Or the fighter jets can also be optimized.

Even if the servo motor is optimized, the value is still not as high as directly optimizing the final products.

"Then let's wait until later."

After all the basic components are built, he can optimize the entire photolithography machine.

However, just as he was thinking this, the phone suddenly rang.

"Huh? Whose phone number is this?"

In doubt, he answered the phone and heard the other person say: "Is this Professor Lin Xiao?"

"It's me, who are you?"

"Hello, Professor Lin, I am a staff member of the National Security Bureau. My police number is There are no other targets in Asia that require the FBI to act like this, and in the next few days, it is the Wolf Prize Award Ceremony, in which only your identity deserves their treatment, so we judge that they may cause harm to you, for your safety , we now remind you not to travel to Israel, and at the same time, your visa to Israel has been rejected by our Ministry of Foreign Affairs."

Hearing what the other party said, Lin Xiao was shocked and frowned: "Is this news confirmed?"

"Please just trust us and we can confirm."

"I understand, thank you very much."

After hanging up the phone, Lin Xiao shook his head.

Unexpectedly, the other party actually did this.

Although this is just a guess, there is obviously no other reason to explain why the FBI would send personnel to Herzliya Pituya just as the Wolf Award ceremony was about to begin.

The National Security Bureau determined that there was no other target worthy of such treatment by the FBI during this time period, so he, a Chinese scientist, undoubtedly became the most likely target.

Then his eyes narrowed, "You want to catch me? I'll make you regret it!"

Originally he wanted to keep a low profile, but now even if he keeps a low profile, it seems that the other party has already set his sights on him.

Looking at the servo motor next to him, he wanted to introduce to that group of people what a surprise is!
