Chapter 318 Time is on my side (2-in-1)

The structure of a microwave oven is not complicated and consists of seven main parts.

The first is the oven cavity, which is the place where food is heated. It is made of non-magnetic metal. The size of the oven cavity is limited. The side length is generally a multiple of one-half the wavelength of the microwave guide wave. In this way, when the food is heated

, can maintain the resonance in the furnace cavity.

Next is the time power controller, which is the switch that controls the power and running time of the microwave oven.

Then there are the waveguide and the rotating table. The function of the waveguide is to transmit microwaves to the oven cavity to heat food; the rotating table is the rotating plate at the bottom of the microwave oven, which can be driven by a small motor.

The structure of these four parts is relatively simple, and the manufacturing process is not complicated. Even if it is handed over to a small workshop, there will be no problems at the technical level.

The real technical content is the other three parts, which are the three major parts of the microwave oven.

The first is the transformer. The transformer of a microwave oven is different from an ordinary power transformer.

The change of an ordinary power transformer is fixed, and the output voltage always follows the change of the input voltage according to the transformation ratio.

The magnetron of the microwave oven needs high voltage to start, and after starting, it operates at low voltage, so the microwave oven's transformer must have the characteristics of high no-load output voltage and rapid decrease in output voltage when the load is connected, which means that the transformer silicon steel core

The magnetic permeability is much higher than the silicon steel sheet of Pudong transformer.

At that time, domestic technology could still make microwave oven transformers. For example, when Galanz introduced microwave oven production technology, it found that the only thing it could make was transformers.

The second largest piece is the oven door of the microwave oven. The oven door is also the front wall of the microwave oven cavity and is the most important barrier to prevent microwave leakage.

The working principle of microwaves is to quickly vibrate the molecules of proteins, lipids, sugars, water and other substances in food, causing them to collide, squeeze, rub and rearrange with each other, thus generating a large amount of heat in a short period of time to achieve heating.

The purpose of food. This will obviously cause harm to the human body.

Therefore, the oven door of a microwave oven must play a role in blocking the penetration of microwaves. This is not just a simple door, but also includes safety protection measures such as oxygen carrier rubber, oven door sealing system, and door lock system.

The door glass of a microwave oven is not ordinary glass, but is made of multi-layer materials with a metal mesh, stamped metal plate or metal film in the middle to block microwaves.

Before the 1970s, microwave ovens could not be widely promoted because the oven door was not made well. Later, the door problem was solved, and household microwave ovens began to enter thousands of households.

The most important of the three major components of a microwave oven is the magnetron, which is also the heart of the microwave oven. The microwaves generated by the microwave oven are emitted by the magnetron.

Humans invented the magnetron thirty years ago. During World War II, magnetrons were mainly used in military radar transmitters and later in microwave ovens.

The technical difficulty in the production of microwave ovens is the adjustment of the magnetron, which is also the core content of the technical guidance provided by Nakano Co., Ltd.

Li Weidong owns a microwave oven production line and can produce microwave ovens, but whether the microwave oven produced is up to standard depends on how well the magnetron is debugged.

When Galanz first introduced the microwave oven production line, many of the first batch of microwave ovens produced were too powerful or started too slowly. The fundamental reason was that there were no technicians to debug the magnetrons.

Li Weidong spent a lot of money to hire Tang Renjie because Tang Renjie was an expert in microwave transistors at Component Factory No. 5. Microwave transistors are an upgraded product of magnetrons, and the principles between the two are similar.

Now, since Nakano Co., Ltd. wants to go back on its word, Li Weidong does not expect Masaki Nagai to provide technical support.

Even if Masaki Nagai provided technical support, Li Weidong would not dare to use it. If Masaki Nagai deliberately misbehaves in the name of providing technical support, it will be Li Weidong who loses in the end.

You still have to be wary of others!

Fortunately, Li Weidong still has backup. Tang Renjie has received a high salary and a house in Shanghai. Now it's up to him to play a role.

…

The next day, Tang Renjie brought the technical team to Qinghe. Immediately afterwards, Tang Renjie and the technical team were taken to the workshop.

Looking at the equipment in the workshop, Tang Renjie sighed softly: "Director Li, I think the equipment in your factory is more advanced than the equipment in our No. 5 Component Factory!"

"This microwave oven production line uses Hitachi's technology, which is relatively new in the world. Otherwise, I wouldn't have spent so much effort to import it from Japan." Li Weidong said.

"Hey! If our component factory No. 5 had been willing to spend money to update equipment, we wouldn't be like this half-dead state today!" Tang Renjie said with a sad look on his face.

Li Weidong persuaded: "Tang Gong, the nature of the company is different, and the times are also different. For companies like the Fifth Component Factory, it is not up to you to decide what kind of equipment to buy."

Semiconductor is an industry that is changing with each passing day. It is like sailing against the current if you do not advance or retreat. When you wake up and the emergence of a certain new technology, the entire industry will undergo a revolutionary technological innovation. Those companies with backward technology will inevitably be eliminated.

.

As the leader in the domestic semiconductor industry, Component Factory No. 5 once had its glory days. However, it was slow to catch up in the huge waves of the semiconductor industry. As a result, it was eliminated by the market in just a few years.

Li Weidong himself grew up in the environment of a state-owned enterprise, and he also knew that people of Tang Renjie's generation were full of affection for the company he had served his whole life. Even though Tang Renjie has retired, deep down, it is still difficult to let go of Component Factory No. 5.

Tang Renjie was melancholy for a few seconds, adjusted his mood, and then said, "Director Li, before I came here, I was a little worried about whether I could give you technical support. Now that I see your advanced production

I feel relieved about the equipment!"

"Then it's up to you, Mr. Tang!" Li Weidong paused, and then asked: "Mr. Tang, I am a layman in terms of technology, so I would also like to ask a layman, how long does it take you to complete the adjustment of the magnetron?

?”

Tang Renjie thought for a while and said: "It will take a month no matter what! I can't guarantee the specific time. No one can say for sure about scientific research and technology."

Li Weidong breathed a sigh of relief. The contract signed with Nakano Co., Ltd. stipulated that the production line would be activated within three months. Now it seems that there is still plenty of time.

…

Li Weidong did not tell Nagai Masaki about the arrival of Tang Renjie and the technical team. This involved commercial secrets and must be kept confidential.

Not only must it be kept secret, Li Weidong must also continue to deal with Nagai Masaki, giving Nagai Masaki a false impression and making him think that Nakano Co., Ltd.'s plan is being implemented smoothly.

Before Tang Renjie's team completes its work, Li Weidong will definitely not reveal his trump card. If Masaki Nagai realizes in advance that there is a technical team behind Li Weidong and goes back to report to Nakano Co., Ltd., Nakano Co., Ltd. may come up with another conspiracy.

Invite.

So the next day, Li Weidong started negotiations with Nagai Masaki again.

…

"Mr. Nagai, we really can't fulfill the request you made. Enlarging the windows and treating the ground with static electricity are fine, but installing air conditioning is simply impossible!"

Li Weidong paused and then said: "China is still relatively poor. For the Chinese, air conditioning is still a relatively luxurious household appliance. Most families cannot afford to install air conditioning, so I would like to ask Mr. Nagai to consider China."

national conditions!”

Nagai Masaki still insisted and shook his head: "No, the construction of the factory must strictly follow the standards!"

"Mr. Nagai, why don't we put aside the issue of installing air conditioners first? It's autumn now, and winter is about to enter. Even if we install air conditioners, it doesn't make sense. Let's put the production line into operation first, and the air conditioners will wait until summer.

Install!" Li Weidong said.

"Haha, don't think that you can deceive me with this delaying strategy!" Masaki Nagai thought to himself, and then shook his head firmly: "If even the factory buildings are not up to standard, my team will not be able to carry out the next step of the work.

"

"Mr. Nagai, I think Nakano Co., Ltd. also hopes that the microwave oven production line can be opened as soon as possible, right? If you start the production line one day earlier, you can supply Nakano Co., Ltd. one day earlier. You, Nakano Co., Ltd. will also get profits earlier, and you can't be more rigid.

In a factory!" Li Weidong said.

"Of course we at Nakano Co., Ltd. hope that the production line can be started earlier, but we need products that meet standards. If we don't have a factory that meets standards, how can we produce products that meet standards?" Masaki Nagai said with a look on his face.

Said calmly.

Li Weidong deliberately emphasized his tone: "Mr. Nagai, my factory can fully meet the production needs. Otherwise, I would not be able to become the foundry of Xizhi Electric! I don't think you, a company mainly engaged in agricultural machinery, have higher standards than Xizhi."

The electrical appliances are even higher!”

Nagai Masaki chuckled and continued to practice Tai Chi: "Mr. Li, every company has different standards. I won't comment on the standards of Nishiba Electric, but the standards of our Nakano Co., Ltd. are like this."

Li Weidong's face darkened, and he deliberately said in a stern tone: "Mr. Nagai, I think you are deliberately making things difficult for me!"

"How could this happen? I was performing my job." Masaki Nagai spread his hands.

Li Weidong said coldly: "Mr. Nagai, if you insist on installing air conditioning in the factory, I will report this matter directly to Nakano Co., Ltd."

"It's up to you!" Nagai Masa pouted, as if he was a dead pig not afraid of boiling water, and then said: "I believe that the club will recognize my serious and responsible work attitude!"

…

After walking out of the negotiation conference room, Li Weidong's originally angry expression returned to normal in an instant.

Ma Zhongyi, who was standing next to him, came up and asked, "Weidong, what should we do next?"

"Let him dry out for a few days!" Li Weidong said calmly.

"Then do you really want to go to Nakano Co., Ltd. to report this matter?" Ma Zhongyi asked again.

Li Weidong nodded: "Of course, I always do what I say! I will write a letter later and send it to Nakano Co., Ltd.!"

"Write a letter? Isn't this too slow? Don't you have the phone number of Nakano Co., Ltd.? Can't you just call?" Ma Zhongyi asked subconsciously.

"What I want is to be slow!" Li Weidong smiled slightly and continued: "Otherwise, how can we delay it for a month? By the way, the letter must be stamped, so that it looks like a formal document!"

…

Masaki Nagai, who had been left out for more than a week, was holding a telephone receiver, and opposite him were senior officials of Nakano Co., Ltd.

"Nagai-kun, that Li Weidong did complain against you, but he didn't call you. Instead, he wrote a letter of complaint and sent it to our club. We just received it this morning." said the other end of the phone.

.

"Writing a letter? That's so slow. No wonder I waited for a week! This is such a waste of time!" Nagai Masaki said jokingly; "Doesn't he have our club's phone number? If I had known this, I would have

Tell him your phone number!"

"The letter of complaint against you has a seal on it. I think the Chinese regard it as a formal official document!" said the other end of the phone.

"How are you going to reply to the Chinese?" Nagai Masaki said.

"We will tell the Chinese people that you are doing your job conscientiously. The headquarters appreciates your work attitude very much and recognizes your work performance." The other party paused and then said; "We have also made a plan.
