Chapter 483 It’s finally Lao Li’s turn
“You mean that rotary scanning system? Well, it’s been made, but if you still can’t make it with the drawings, then it’s really better to go home and sell sweet potatoes. But it’s still being tested. , I guess it will be almost done after New Year’s Day.”
It’s good news when Lu Gong opens his mouth.
Then it’s almost time to test the core of the line scan thermal imaging camera. Although the semiconductor cooling has not been completed yet, we need to find a vortex tube compressed gas cooling device from the Guangdong Research Institute and connect it to a larger compressed air Gas bottles cannot be used in a short period of time.
Gao Zhendong put down the phone and rubbed his little hands excitedly.
Before I had rubbed it a few times, the phone rang again.
There are more and more things happening, Gao Zhendong sighed while picking up the phone.
The call came from comrades from the 12th Machinery Department. After more than ten days, they finally figured out the overall situation of domestic rotary encoders.
Putting down the phone, Gao Zhendong went to his e-mail and received a letter.
The letter has an attachment, which is an investigation report on rotary encoders.
Gao Zhendong opened it and took a look. The report was very detailed, but it could be summed up in just one word.
——Missing!
There is a lack of stable supply of rotary encoders in China. The limited ones are imported from abroad and there are no multi-turn rotary encoders that meet Gao Zhendong's requirements.
There is a rotary transformer, which is also a type of rotary encoder. It relies on the voltage waveform output by the rotating transformer to determine the rotation state. It is an analog encoder.
You can have multiple circles, generally speaking they are relatively coded, but the advantages and disadvantages of this thing are equally obvious, and Gao Zhendong cannot use that advantage.
It can be used for high speed, high and low temperature, and impact resistance, but this is of no use to Gao Zhendong's idea.
On the contrary, it is because the encoder itself is complex, the analog output is troublesome to solve, the requirements for the acquisition circuit are high, and the cost of the entire system is high.
Forget it. After all, Gao Zhendong wants to use a micro-projection lithography machine. The output of this thing will not be too high, and it is not unbearable to be expensive. The key is that the imported rotary transformer at this time is reliable. The performance and accuracy are quite mediocre, which is hard to bear.
In fact, there is another thing called a mechanical encoder, but it is basically not available in China. If it is available, it is some highly targeted specialized equipment that needs to be transformed into photolithography machines. The movement of B on the workpiece table seemed to Gao Zhendong more troublesome than getting a new photoelectric encoder.
After thinking for a while, Gao Zhendong began to write a reply on the computer.
Not long after, the typed copy of this letter was transferred to the desk of the leader of the 12th Machinery Department. He had told him that he must go to his place to see the news about Gao Zhendong from the 17th Machinery Department.
While reading it, the leader discussed the letter with the comrade who sent it.
“He wants a multi-turn encoder with stable performance and higher precision?”
The comrade who sent the letter said: “Yes, he asked us about it more than ten days ago. This is what he replied after receiving our survey results about the current situation of domestic rotary encoders."
"It seems that he is not satisfied with it now. Well, since the usage is not large, he suggested that it can be passed. The Ministry of Foreign Trade seeks imports from Oceanic Convention countries such as Gallic chickens, or East Hans cats. It seems that he is quite economical and uses less, so he directly seeks imports."
The comrade who delivered the letter shook his head: "Not entirely."
"Not entirely?" the leader of the 12th Machinery Department asked, turning a page, and then his eyes widened.
“If there is any disharmony regarding import matters, and those within the Twelve Machinery Department system who are interested in this matter, please contact me. I have some thoughts on this, and if many parties work together, we should be able to accomplish this. ”
Gao Zhendong follows Lou Xiaoe every day to read the thread-bound leisure books bought by Pan Jiayuan. His speech is normal, but when he writes letters, he gets a little lost in words. Fortunately, the leader of the 12th Machinery Department is also a former military officer. The kind who can command thousands of troops and thousands of horses, and can write thousands of words and ink, can understand it at a glance.
——I can do it. If you want to do it, come to me!
In his opinion, this is what Gao Zhendong meant.
He guessed right. For Gao Zhendong, as long as there is a factory willing to be a tool maker, it is not difficult to make a usable photoelectric multi-turn relative encoder. This thing does not even have much processing technology. High requirements.
The leader of the 12th Machinery Department immediately put the document: "Immediately send a notice to the factories that make electronic devices in the system to recruit talented people. Choose one who is willing to work with high enthusiasm and strong technical ability, and let them go Find Gao Zhendong!”
Gao Zhendong is a ruthless person, if you can’t do it, do it yourself!
He didn't doubt whether Gao Zhendong could make it at all. He probably asked the comrades from the 12th Machinery Department to find him simply because he was too busy with too many things, such as the rotary encoder. The things weren't big enough for him to do it himself.
But this does not mean that the rotary encoder is useless. This thing has many uses in automatic control systems. Our country produces this thing. It is said that a special organization was originally established for this thing in 1965, but it was not until 1982 that it was Production officially started. In the view of the leaders of the 12th Machinery Department, any hesitation for a second about this good thing coming to their door would be disrespect for the rotary encoder.
Import? Importing wool requires foreign exchange. Wouldn’t it be nice to use it to buy food or something? Besides, it’s hard to say whether it will be sold or not, so I won’t bother the comrades from the Ministry of Foreign Commerce.
Gaul Chicken: Why the hell did you ask? How dare you assume I won't sell?
To be honest, Gallic chicken at this time, for things like rotary encoders, as long as it is available, it is really sold.
At this time, it was also the end of the year, and they were looking at the annual import and export list, feeling a very strong and strange emotion.
“My dear Le Goff, that country in the east is an agricultural country, isn’t it?”
“Yes, Mr. Senna, without a doubt.”
“ Compared to them, we are an industrial country, right?"
"This is an irrefutable fact, Mr. Senna."
"Then tell me why they export to us computers, intellectual property licenses, complete sets of computer software, and special steel, while what we export to them is urea, grain, urea, grain..."
< br>"This...this is only temporary. Moreover, we still exported some integrated circuit chips to them, sir."
"Then please explain why the things they shipped were all shipped on a cargo ship. It’s not enough, but we need a lot of ships to transport it? I have to remind you, it’s Citigroup’s, not ours!”
“Ours. The export volume of goods is relatively large, Mr. Senna. "
"Enough Le Goff, I am not one of those idiots in the House! Next year, this situation must be reversed, and we must deserve our status as an industrial country. "
"Okay sir, I will add this matter to my memo. This is their latest export product list. Are you interested in taking a look? There are some very interesting things." Legoff was very cooperative. He took note of Senna's words and then took out another document.
This made Senna furious: "Get out of here! Legoff! They won't even think of making another coin from me within this year!"
"As you said I hope Mr. Senna, we will discuss this matter next year.”
This list also flew to the other side of the ocean, but it was in the form of a film in a foreign affairs airmail package, but it was very fast and did not even last longer. The time it took for this list to circulate through the Gallic Chicken bureaucracy.
The Citizen was also very interested in the trade between the Gallic chickens and the Eastern countries on their backs.
"E-mail system? What is this?" asked an intelligence analyst at Langley Center, looking at the newly added items on the list. This was beyond the scope of his understanding.
"It seems that electronic technology is used to transmit emails. Maybe this is a telegraph system." Another employee who is more familiar with this gave his own opinion.
“HolyShit, this thing is actually more expensive than their computer!” An employee is sensitive to economic issues.
"Oh, then I think this thing should be called 'Advanced Telegraph System', or ATS (Advanced-Telegram-System) for short."
The Citigroup once again used their talent in naming , just like their future STEED (Silent-Tactical-Energy-Enhanced-Dismount, strength-enhanced silent tactical cart) with a research and development cost of 800 million U.S. dollars and a purchase price of 170,000 U.S. dollars.
Although everything is expensive if it has the word "tactical" in it, the two-wheeled bike Citigroup is obviously a bit ridiculously expensive. Maybe it's because the name is too good, or at least it's long enough.
For knowledge, when searching for "tactics XX" on shopping software, remove the word "tactics" and search again. You may be surprised.
“I think we should consult AIEE or IRE.” The Langley Center still has knowledgeable people, AIEE (Citigroup Electrical Engineers) and IRE (Institute of Radio Engineers), both of which are members of the IEEE predecessor.
"OK, I'll ask next year." The original employee joked, adding that it is now December 31, 1960, Saturday.
——
On the same day, Sha Zhu’s report on their self-heating food and fireless self-heating patch was brought to Deputy Director Li by Sha Zhu.
Although Gao Zhendong doesn’t take this thing seriously, for Lao Li, who is in charge of logistics, it is like a giant pie falling from the sky.
Deputy Director Li still got a bit of profit from the projects and topics that Gao Zhendong and the others worked on before, but unfortunately he was not in the technical line, nor in the production line, nor was he the number one, no matter how much he got involved , and he couldn't get the big head, which made him quite regretful.
Suddenly he saw the cook in the cafeteria coming to him with a scientific research project focusing on the cook, and also said that it was a serious project that Gao Zhendong of the No. 3 Factory proposed and personally approved and helped. This made him Deputy Director Li couldn't help but feel that "it's my turn."
Regardless of the size of these two topics, the fact that the research content really falls within the professional scope of the logistics system he is in charge of is enough for him to devote all his efforts to it. This is why Gao Zhendong just gave up and let Silly Zhu do it. The reason for looking for Lao Li.
