Professor Tang took a closer look at the drawings and found that there were indeed some differences.
There are some circuit designs, Su Qiao's is a little more complicated, and Chen Xiao's is a little simpler.
But Chen Xiao simply looks more reasonable.
There are also slight differences in the content of some circuit designs.
On the surface, the results for both motherboards should be the same, but if the results are the same, why are there two designs? Is it just to avoid duplication of motherboard drawings?
Professor Tang's face darkened, and now he was a little confused.
If it is said that Chen Xiao plagiarized Su Qiao, then how can we say that Chen Xiao invented a very high-tech visual operating system for CNC machines?
The members of the expert group were also in an awkward position.
Chen Xiao's inherited circuit diagram was designed so cleverly that even experts could not tell the consequences of the difference between the two drawings.
At this time, Xiao Wang, an office worker, came in to pour water for everyone.
I had been listening to what they were saying about Chen Xiao and Su Qiao, and suddenly I remembered something.
Xiao Wang said: "Chief Luo, I think I got a letter for you from the guard some time ago. The signature on the envelope was called Chen Xiao, because my child is named Wang Xiao, so I still remember this name. "
Luo Hai was stunned for a moment and said, "You said Chen Xiao wrote me a letter? When was it?"
Xiao Wang thought for a while and said, "It's been a while, and I can't even remember it."
Luo Hai asked hurriedly: "So, where did you put that letter?"
Xiao Wang said: "It will be placed on your desk together with the newspaper that I usually give you."
Luo Hai quickly got up and went to the office.
There are many newspapers ordered by the bureau, and Luo Hai doesn't read every one.
He took out the ones he was more interested in and looked at, and threw aside the ones he was not very interested in. Someone would come over every month to collect them and sell them.
Sure enough, Luo Hai found the unopened letter in the corner of the office, between the two newspapers.
The signature of this letter is indeed Chen Xiao.
Luo Hai took the letter to the conference room.
He looked at the date the letter had been sent; it had been several weeks ago.
In front of everyone, Luo Hai opened the letter.
Inside there was a letter and a drawing.
The content of the letter is very short. Chen Xiao wrote: Xia is a country with a large population, and it will also be a big country in science and technology and industry in the future. CNC machine tools are one of the basic technologies for the development of industry. The core technology should not only be in the hands of Westerners. inside.
Chen Xiao wrote:
He is more interested in integrated circuits. After studying Demagee's five-axis CNC machine tools, he found that Demagci's CNC machine tool integrated motherboard design is complex and can be optimized.
Although the optimized motherboard occupies a larger area, the circuit diagram will be simpler.
Many Xia Guo electronic companies can produce this kind of simple circuit diagram, and this one is helpful to the development of Xia Guo's CNC machine tool industry.
Based on the above reasons, I sent the circuit diagram of the CNC machine tool motherboard I designed to the National Patent Office, hoping to make some contribution to the development of the country's CNC machine tools.
Chen Xiao's handwriting is not very good, and even has a bit of a squeaky feel, but every word is very simple and can fully express an ordinary high school student's desire for the country's scientific and technological progress.
Luo Hai expressed Chen Xiao's belief in public.
Then Luo Hai took out the circuit diagram inside the letter.
The experts immediately looked carefully at the drawings.
After careful comparison, everyone was surprised to find that although the drawing in the letter was a copy, the original was completely hand-drawn.
And this circuit drawing in Chen Xiaoxin. It is completely consistent with the drawings that Chen Xiao applied for a patent with ADLINK.
When Luo Hai looked at the postmark, it was weeks earlier than when Su Qiao applied for the patent.
This shows that Chen Xiao applied for a major earlier than Su Qiao applied for a major.
From this point of view, everyone has already concluded who invented the CNC machine tool motherboard first.
In fact, the expert group is already inclined to grant the patent to Chen Xiao.
Wu Geng, a microelectronics expert at Yenching University, said very excitedly: "Look at the application documents, Chen Xiao is just a senior in high school? Such an outstanding student must be well cultivated!"
Wu Geng said: "Professor Tang, there is no problem in recruiting students with special talents in advance, but you may have got the wrong person. This Su Qiao may not really be the inventor of CNC machine tools."
Wu Geng kept looking at the letter written by Chen Xiao, "I want to report this matter to the school. If Chen Xiao is really only a senior in high school, I strongly demand that Yenching University can admit Chen Xiao in advance! Such talents are rare!! "
If Professor Wu Geng knew that Yenching University took the initiative to eliminate Chen Xiao, I wonder if he would be so angry that he would vomit blood.
Professor Tang was already very embarrassed at this time, and even felt a little unbelievable.
Professor Tang said with some excitement: "It is very strange that two patents were applied for at the same time this time. We cannot make a judgment based on two patent application descriptions or a letter."
Experts also think this is true.
This patent application can be said to be very valuable, but it is very strange that two people applied for a patent at the same time, but the drawings are slightly different.
A member of the expert group suggested: "I think we should go to the site to take a look. Doesn't Su Qiao's patent application say it has been applied? We can go to the site to take a look and then we will know the answer."
After the panel made this recommendation, the decision was left to the patent office.
Zhang Bo said: “Our expert group reviews and evaluates invention patents, and one of the contents is that if necessary, we must go to see the patented product on site.”
"These two patents for CNC machine tools involve the development of our country's industry, and even more so the progress of the country's CNC machine tool industry. It can be said that they have a great impact!"
"Now that everyone has this request, I will immediately report it to the superiors. If there are no problems, we can set off to Jiangzhou and Jiangcheng in two days to check what is going on."
The National Patent Office went to Jiangzhou and Jiangcheng to check what happened.
At this time in Jiangcheng Machinery Factory.
Since Su Desheng has gone to Jiangzhou to take up a post, Director Liu, who has just taken office, is full of ambition and ready to do something in his career.
But he encountered a very difficult thing within just a few days.
The motherboards of more than a dozen CNC machine tools in the factory actually burned!
Director Liu was shocked.
He had just taken office, why did he encounter such a big thing?
No matter how stupid Director Liu is, he still knows that this batch of CNC machine tools is worth a lot of money.
He asked the factory's technical department to thoroughly investigate the cause of the accident.
At this time, Director Liu also received news.
This batch of equipment has been burned once before.
