The ups and downs of life in the Siheyuan

Li Lou was a figure in the emperor's period. He could see everything clearly from a hundred steps away.

The clairvoyant in Journey to the West refers to Li Lou.

When determining the model, people in the laboratory participated in collective discussions, and finally decided that the unit name was HB, which stands for Huaxia Semiconductor.

LL is the pinyin initials of Li Lou.

Li Lou was proposed by Teacher Ai. He had done a lot of research on Journey to the West and felt that clairvoyance was more suitable for this chip.

So everyone passed it unanimously.

HB was proposed by Huang Yan. Li Yuan felt that the name was a bit too big, but everyone else agreed.

They clamored very confidently that 621 Laboratory is definitely the leader of China Semiconductor.

When Representative Tong saw the five chips, such a steady person, his face flushed.

"How to use this?"

"Wait a minute, I'll write the instructions right away." Li Yuancai remembered that there must be instructions when delivering.

While writing the instructions, Li Yuan suddenly stopped writing.

Representative Tong, who had been standing by his side, immediately asked: "Is there any difficulty?"

"Representative Tong, what are you going to do with it when you take it back?"

"Solder it directly. This is much easier than soldering a large number of components!"

He has been staying in the laboratory recently and has a very clear idea of ​​the chip design.

When he first listened to the technical PK meeting, he just knew that the chip was a bit powerful.

As he learned more about the plan, he had a clear understanding of the chip, and he was even more impressed by this genius idea.

When he went back to report midway, he seemed to have become an expert on chips.

Those researchers were so itchy that they wanted to go to the laboratory to study.

But it has never been approved.

Let's go back to the lab.

When Li Yuan heard what Representative Tong said, he knew that they didn't know how to use the chip.

"Senior Brother Gong, how is the research on the circuit board going?"

"We will definitely be able to determine the craftsmanship in another month!"

"It's too late, let's do this. Brother Gong give me some copper-plated plates first."

With doubts, Gong Liming took over a one-foot-square copper-plated plate.

Li Yuan picked up the pen and began to design the circuit on the scratch paper.

As a result, he was just as stunned as he was holding the pen, and he found that everything had to start over.

The working voltage of this chip is 5V, but the power supplies used on site are all kinds of strange.

供电电压有24Vdc、25Vdc、28Vdc、48Vdc、60Vdc。

"Representative Tong, please help me ask, what is the power supply voltage of the radar display unit?"

"Okay!" Representative Tong ran towards the welding machine excitedly.

"Wait a minute," Li Yuan had to stop Representative Tong again.

It suddenly occurred to him that there seemed to be no concept of EMC in China at present.

For electronic products, EMC is the biggest threat.

For example, power surges, static electricity, electromagnetic radiation, signal conduction, etc., all of which will affect the normal operation of electronic products.

It may even directly burn the equipment.

Therefore, he must consider EMC protection.

The most direct method at present is definitely the Faraday cage, which is to wrap the entire circuit with a metal shell.

At the same time, EMC protection needs to be considered on the interface side.

With this in mind, he began to draw.

Before noon, he put the drawings in the drawer.

"Guys, I will officially get married tomorrow. I will get off work early today and go home to prepare."

When everyone heard this, there was a burst of congratulations.

"The current situation is special and I won't be hosting a banquet, so I won't invite everyone tomorrow."

"Ah!" Everyone actually wants to attend tomorrow's banquet.

Everyone knows that the current situation is indeed not easy to handle.

"As compensation, I will pay for extra food tomorrow."

"Then we will wish the director tomorrow." Everyone sent their blessings one after another.

After Li Yuan left in the afternoon, Representative Tong answered a phone call and left the laboratory with three chips.

Li Yuan first went to the department store to find Brother Yang and bought a new bicycle.

The bicycle I have been riding now is too old and it seems inappropriate to use it to pick up relatives.

Then I went home and prepared a chicken, a 5-pound carp, 13 pounds of pork, and some common vegetables such as cabbage, potatoes, dried mushrooms, fungus, and yuba.

I found the big red words "Happy" that the third aunt helped to cut out, and prepared the paste, just waiting to be pasted on the window tomorrow morning.

Lay out the red quilts and mattresses, and put on the mandarin duck pillows.

These were sent over by my mother-in-law’s family a few days ago.

Under the watchful eyes of the neighbors who entered the compound for the second time, Li Yuan moved the dowry bedding home.

Of course, in Courtyard No. 95, it was also rumored that Yang Ting's parents were very particular people and were willing to spend money on their daughter's wedding.

Yang Ting can hold some other bits and pieces tomorrow.

At 4 o'clock in the afternoon, the third uncle returned to the compound on time. Instead of going home, he knocked directly on the east wing.

"Third uncle, as agreed with you before, you three uncles in the courtyard will help me bear witness tomorrow.

We will open a table tomorrow and He Yuzhu will help manage it. I will leave the rest to you, Third Uncle."

"Don't worry, I'll go find Lao Yi and Lao Liu later."

"No, to show respect, I will invite you in person later."

"Don't do it. If you don't do anything, I'll be the one to notify people. Otherwise, when you go to Lao Yi's house, why don't you call me Auntie?"

It's different when I go, I can tell who to invite directly."

Since we live in a compound, for such a big event as a wedding, we must invite three uncles.

Although he looked down on the other two, he didn't want to break the rules of the courtyard for such a festive event.

Thinking of this, he had to consider the situation of other residents in the courtyard.

It is customary to send gifts or food stamps to attend a wedding.

Gifts usually include washbasins and kettles. Warming kettles are too expensive, so several people usually work together to buy them.

Now that supplies are so scarce, no one can bear to ask them to pay for this.

He doesn't need to accept gifts. There are enough supplies in the space, so he can treat everyone in the hospital to a meal without any pressure.

However, marriage in this period was given too much revolutionary color. Low profile overwhelms everything.

Therefore, when Yan Fugui proposed that he would arrange everything, Li Yuan nodded in agreement.

"Others in the courtyard, please help explain. Now that supplies are tight, it is not appropriate to hold a large wedding."

"Don't worry, the third uncle will take care of this for you."

Then, Li Yuan explained tomorrow's guests.

Such a number is actually quite a lot.

There are three uncles in the courtyard, He Yuzhu's family, Director Wang from the street, and Uncle Song.

Counting him and Yang Ting, there are 10 people in total.

Fortunately, the long table in the living room is long enough, so I can sit there when the time comes.

Sunday, May 1963, 1.

Early in the morning, after Li Yuan finished his morning classes, he started boiling water, cleaning the house, and scrubbing the bicycle.

At 7 o'clock in the morning, Yan Fugui and Shazhu's family came over at the same time.

He Yuzhu went directly into the kitchen to start making preparations, and Tian Xiujuan started to post happy words.

Yan Fugui helped check the items needed to bring to the wedding: 1 catty of bacon, 1 catty of candy, 2 catties of cakes and a carton of Hongtashan cigarettes.

These must be carried in net bags so that all neighbors can see them.

As everyone gets busy with their work, the atmosphere at home becomes more and more intense.

"The auspicious time has arrived, and it's time for Li Yuan to set off to pick up the bride," Yan Fugui promptly informed Li Yuan.

"Order!"

A handsome young man, dressed neatly, with a red flower on his chest and a brand-new bicycle on his crotch, appeared on the road with a grin on his face.
