The ups and downs of life in the Siheyuan

Chapter 252 Project worth 10

The sudden loud noise startled Li Yuan.

His expression did not change, "Okay, it's okay, the lift has been adjusted in place, don't move any more."

He looked at the vacuum furnace operator and said, "Activate the vacuum button."

She hurriedly pressed the switch, and after a few dozen seconds, the vacuum began to increase.

After 1 minute, the color of the regrown single crystal rod below the single crystal rod returned to normal.

This time, the vacuum furnace operator did not dare to look at the silicon liquid level or the single crystal rod and kept his eyes on the vacuum indicator.

Half an hour later, a standard-sized single crystal rod appeared on the workbench.

The only flaw is that one section is the wrong color.

"Master Xiao, you are the best at the next work. You can guide them."

Engineer Xiao smiled and said, "Push the single crystal rod and follow me to the cutting workshop."

The director of the branch factory only had eyes for the single crystal rod. Now his face was red with excitement and he followed into the cutting workshop.

Only the operator of the lift vacuum furnace remains here.

Li Yuan looked at the girl who controlled the vacuum just now, "I'm sorry, I was distracted just now."

"It's good to know the reason. You must pay attention in the future. Now is the practice period. There is no big problem. In the future, it will be officially put into production. You all have to pay 12% attention."

"I understand, Li Gong," they both agreed.

Cutting is relatively simple, just fix the single crystal rod and leave everything else to the machine.

The only thing you need to pay attention to is manually adjusting the feed.

The cutting machine has a sealed cover, and distilled water is continuously injected into the cutting position to ensure that no dust is generated.

All the problems encountered in cutting were solved during the prototype, so the cutting was very smooth.

After successfully cutting 5 wafers, the large team moved to the polishing workshop.

This level will test the operator's touch, and there are no shortcuts.

Unlike later generations, these have precision machining equipment and testing equipment sufficient to ensure acceptable polishing.

The two stayed in the factory for another two days, teaching them all the subsequent processes.

Returning to the underground laboratory of the maintenance plant, Representative Tong also came in.

"I heard that you are researching chips?"

Li Yuan looked up at him and said, "Representative Tong, you are well-informed.

We now want to design a dedicated chip for vacuum furnace automatic control."

Li Yuan did not hide it, because once the research and development is successful, the vacuum furnace of Factory 700 will definitely be upgraded.

“We now have a project, which is an anti-artillery radar, and the West is currently studying it, and we are also conducting preliminary research.

The biggest problem now is ballistic calculation. The most suitable one at present is the 911 computer.

Unfortunately, it is too bulky and cannot meet the needs of the battlefield.

Now we have begun research on transistor computers, which can be a good replacement for 911 computers.

However, we still feel that it is too large and consumes a lot of power, which is not conducive to use on complex terrain.

I heard that you are researching special chips, so I wanted to ask you if there is any way to solve our problem? "

Li Yuan fell into deep thought. Later generations saw a promotional video recording the development of our military's radar.

In the late stage of the self-defense counterattack in southern Xinjiang, our army's anti-artillery radar can identify the enemy's artillery positions within 10 seconds, and a counterattack can be launched immediately.

The fiercer the enemy's shelling, the more severe the losses. In the later stages of the war, the enemy did not even dare to fire.

It was imported from the Empire on which the Sun Never Sets at a high price. I can’t remember the specific model, but it’s really easy to use.

Thinking of the difficulties at the beginning of the southern Xinjiang campaign, he also wanted to contribute.

"How's our radar technology?"

"Currently, our most equipped equipment is the 314B medium-range air defense meter wave warning radar, which is a product produced by Dianke 14."

Then, he took out some information, including the structural block diagram of the 314B radar.

该雷达发射功率提高到了140-160千瓦，重达400多千克，具有80-100千米的飞机探测距离。

What surprised Li Yuan was that it was equipped with a flat position display.

Although I don’t understand the principles of radar, the basic circuit skills book is not free.

You will soon understand its working principle and interface definition.

At the back is a design diagram of an anti-artillery radar. The module marked with a question mark is the computing unit.

According to the program requirements, the principle of positioning artillery positions is relatively simple.

By identifying the three points of the artillery shell in the air and quickly calculating its trajectory, you can find the artillery position.

He closed his eyes and meditated, his brain simulated at high speed, and he quickly came to a conclusion.

"It can be done".

When Representative Tong heard this, he immediately sat up straight and asked, "How long?"

"Give me 3 months".

"Hahaha, great, do you know the research hours of the Computing Institute?"

Without waiting for Li Yuan to answer, he gave the answer: "Two years! 100 million R&D funds.

It's his grandma's, I have to go back quickly, I can't let them do anything wrong."

After saying that, he left in a hurry.

"There's a phone there," Li Yuanqing said calmly, which stopped him in his tracks.

He cursed secretly and ran to the phone in a few steps.

Ten minutes later, he returned to Li Yuan, staring directly at him.

"How sure are you?"

"9% or so."

"I'm not kidding you!" Representative Tong's eyes were a little red.

Li Yuan suppressed his smile and said, "I didn't lie to you, leaving one point is to respect the way of heaven."

"In three days, there will be a technical plan review meeting, and you have to attend."

"What do you mean?"

Li Yuan had just been released and hadn't seen Yang Ting for a long time. He originally planned to go find her in the evening, but another mission came.

"Three days later, there will be a plan review meeting in the Equipment Department. You will be temporarily added to compete with the Computing Center."

"Representative Tong, that's a computing institute, I'm crazy!"

"They want to develop transistor computers and they need funding. We need anti-artillery radar and we have funding.

But after listening to your plan, we want to compare it.

By the way, if you are researching chips, is 100W enough? "

Li Yuan's heart was beating wildly, 100W, what a huge amount of money this is. With this money, the laboratory's funding will be enough for the next few years.

But think about it, if you compete with computing institutes, you have to highlight the advantages of the laboratory.

After all, chips are too advanced. China is still stuck in the stage of replacing electron tubes with transistors and suddenly launched the chip concept.

He was worried that the judges would have other bad ideas.

Thinking of this, he felt that it was time to make a bigger move.

"100W! Not 100W, just 10W, take the chip home."

"What? How much did you say?"

"10W! No more!"

"I'm so confused, how can you let others play with you!"

After that, he left the laboratory in a hurry.

Li Yuan sat in the middle and slowly perfected the plan.

"Director, what were you discussing just now?"

Huang Yan stood behind Li Yuan with a smile, her eyes shining brightly.

“Hey, make money!

If this works, we won’t have to be so humble about applying for funding in the next few years.”
