United States, Boeing Company.
U.S. Air Force Major General Arnold Jr., Virginia Advanced Circuits CEO Fernandez, and Boeing executive Collins were discussing a major decision related to the U.S. Air Force and Boeing.
"The U.S. Air Force discovered complete Chinese transistors, transistor amplification circuits, and computing circuits in North Korea. Then the Air Force handed over these samples to Virginia Advanced Circuits. After one year and four months, they successfully imitated the transistor." Arnold Jr. Said, "Except for some high-power amplifier devices, vacuum tubes have certain value, and all other places where vacuum tubes are used can be replaced by transistors."
Fernandez: "In the recent B-52A bomber upgrade project, we have all witnessed that this new electronic component has a great effect on aircraft performance and weight reduction. These components are produced by our company, or Our company produces modules and then supplies them to manufacturers of radios, alarms, etc. However, our company has a deep relationship with the US Air Force, and when we further expand our business, we will inevitably be affected by this relationship. This is what we propose Reasons to partner with Boeing.”
In fact, Arnold Jr. did not say a word. The reason why he planned to spin off Virginia Advanced Circuits was because Arnold Jr. used a vest to take up shares in the company.But a vest is a vest after all. If you investigate carefully, it is very likely that Arnold Jr. used the transistors seized by the U.S. Air Force to start a company, and it is very likely that it will be discovered.
Collins nodded.
If the talks go through, Collins will be director of Boeing's newly formed Electronic Circuits Division.
Fernandez took out a sample of the transistor produced by the company: "This is a crystal triode imitated by our company. It can be said responsibly that the workmanship is very good, no less than the Chinese transistor on the bomber we found. The manufacturing cost is now 5.5 US dollars each. Although the cheapest small vacuum tube only costs $3~4, the cost of a vacuum tube with a slightly anti-seismic structure can reach more than $6, and the structure of the crystal triode naturally has good anti-seismic ability, and it does not require any reinforcement. Vacuum tubes designed for shock resistance are stronger."
"This is just a consideration of the cost of a single device. When the size advantage of a transistor is used in a weapon system, the performance improvement brought by it is beyond the reach of a vacuum tube." Fernandez took out another small vacuum tube and put the thumb-sized glass Vacuum tubes sit alongside transistors that are a little smaller than a soybean.
Collins: "Boeing's plan is to acquire Virginia Advanced Circuits as a whole, including the company's technology, process, intellectual property, fixed assets, cash assets, and of course cash debt; the company's executives continue to serve in our Electronic Circuits Department, And ordinary employees of the company will consider whether to retain them depending on the situation..."
The three conducted several rounds of negotiations on the details of the acquisition and the amount of the acquisition.
Now that the details have been discussed, Arnold Jr. said: "The Air Force has three additional conditions regarding the transfer and acquisition of the company. Only when these three additional conditions are met, can Virginia Advanced Circuits be acquired by Boeing."
Collins: ?
Arnold Jr.: "First, Boeing's computers and other mechatronic products that use transistors cannot be used by or sold to the U.S. Navy; second, they cannot be used by or sold to the U.S. Army; third, they cannot For use by or for sale to the United States Marine Corps."

If Tang Hua knew that the hard imitation transistors in the United States were actually $5.5 each, he might immediately order Hon Hai to prepare dozens of boxes of second-generation transistors for sale in Hong Kong.
The price difference is so cool.
After the third-generation transistors were put into production, the production line of the second-generation transistors was gradually closed, and now there is the last one, with a monthly output of 5 to 6 transistors.
This was originally considered for use in equipment such as walkie-talkies that are likely to be lost and captured on the battlefield.It doesn't matter if you get caught like this.
Beginning in 1953, televisions and radios also adopted a mixed system of vacuum tubes and second-generation transistors.
And third-generation transistors now have to beware of leaks.Especially in the second half of 1952, planar technology was fully used in the production of third-generation transistors. If enough third-generation transistors were seized, it would be possible to analyze and find that the silicon grains at the core of these transistors seemed to be cut from a whole silicon wafer. of.
Then you can understand: China etched the core of many transistors on a large silicon wafer, then cut the large silicon wafer, cut it into small silicon grains and packaged it into transistors.
Then the Americans may continue to make up their minds...
Thus the secret of ultra-small but cheap transistors was revealed.
……
Televisions and radios were not only products sold to the Soviet Union and Eastern European countries, but also products sold to Europe and the United States from 1953 onwards.
Guangzhou.
In the middle of the night, a bulk carrier docked in Guangzhou. As soon as the springboard touched the wharf, a large team of stevedores quickly boarded the ship to unload the cargo. The cargo on board was unloaded in more than an hour.
Since three years ago, Chuanzai Huo has become a well-known shipping king in Hong Kong and Guangdong.
The maritime blockade was the most severe during the War to Resist U.S. Aggression and Aid Korea. Chuanzi Huo passed through the blockade of the British army in Hong Kong in the dark, and sent scarce supplies from Hong Kong to Guangzhou. For this reason, a ship was sunk by the military commander.
At that time, the only shipowners who dared to eat this bowl of rice were the Lu family. Among them, there were only two shipowners who were the most righteous and recognized by our party: the Huo family in Hong Kong and the He family in Macau.
The goods delivered by Chuanzihuo are never sloppy, such as penicillin, he tries to get the best quality medicine from the general agent.Never take advantage of difficulties to raise prices.The He family in Macau has more imaginative sources of goods. For example, they got a batch of fine rubber seeds from Malaysia, and six months later they simply got another batch of rubber saplings (this is a highly sensitive embargoed material). In 1952, they simply opened up the military supply depot of the Portuguese Army in Macau, and sold thousands of first-aid kits containing penicillin, morphine, hemostatic powder, and bandages.
"Boss Huo," on the pier, the cadre in charge of the handover shook hands with Chuanzi Huo, "It's dark and the waves are rough, and it's not an easy boat trip. Thank you for your hard work."
"Where is it, it is much safer now than last year and the year before last," Chuanzi Huo said, "You have taken care of Taiwan, and all the military and central reunifications have disappeared. Now I don't have to worry about the ship being bombed anymore."
"When we settle down in the future, if there is a chance, we will invite Boss Huo to come here as a guest, maybe we can meet the chairman and the prime minister," the cadre said, "There is another thing. Before your return trip, you transported some groceries and special products. Now The superior has a policy, and the TV, tape recorder, and mini radio are also yours."
In the past, a British company secretly imported TV sets from Guangzhou, but now the British company is too frightened to come here.
"Television? Just the kind of remote-control TV?" Although Chuanzihuo didn't watch TV himself, he knew about it.
"From now on, these goods will be packaged by your Huo family and the Macau He family. You can do business by yourself, and you can throw your hands when you go ashore. You can sell your hands when you go ashore. A TV set can earn about two hundred. Radios and tape recorders, our secretary said , I will give you one each to listen to and play by yourself.”

August 1953, 8, Soviet Union, Semipalatinsk nuclear test site.
The Soviet Union's first thermonuclear weapon, the RDS-6C, has been hoisted on the tower, and only the final detonation order is waiting.
Next to RDS-6C, there are piles of test buildings and test props. The test props include 1300 measuring instruments and cameras, 1700 test objects, 16 aircraft, 7 tanks and 17 artillery pieces.
The RDS-6C is strictly a thermonuclear weapon rather than a hydrogen bomb. ——If the definition of a hydrogen bomb is to ignite fusion material in the form of radiation implosion, resulting in a larger equivalent explosion, then the RDS-6C is not yet.
The radiation-imploding hydrogen bomb Sakharov's team had made a breakthrough, but there were still a few last minor problems to be solved.In this case, using the RDS-6C to explode a shot first can show the public that the distance between the Soviet Union's nuclear weapons research and the United States is actually very close.
The RDS-6C does not use the principle of radiation implosion, but the principle of "thousand-layer cake".In the middle of the bomb is a [-]-ton atomic bomb, which is covered with a layer of lithium deuteride.
After the atomic bomb is detonated, this layer of lithium deuteride will have a small amount of fusion reaction.This fusion reaction is definitely not enough, but fortunately, it can continue to be added.
A layer of uranium-238 is wrapped outside this layer of lithium deuteride.This thing is not a fission charge, and it should have stayed there quietly, but after the nuclear fission of the atomic bomb and the fusion reaction of some lithium deuterides, a large number of neutrons are released. If a neutron reflective layer is wrapped outside the uranium-238, the effect will be better. good.The neutron hits the uranium-238, the uranium-238 decays into plutonium-239 once, and the plutonium-239 undergoes nuclear fission again.
Then you can wrap a layer of lithium deuteride on this layer of uranium-238, and then wrap a layer of uranium-238 outside the lithium deuteride...
That's what it means.
It is generally believed that the puff pastry is an "enhanced atomic bomb", and a fusion bomb that implodes with radiation is called a hydrogen bomb.
The yield of a pure fission atomic bomb is between 1.5 and 6 tons, and it is difficult to make a fission bomb with a larger yield. It is too difficult to arrange uranium blocks so that they do not interfere with each other before they detonate.The enhanced atomic bomb can expand the upper limit of the yield to about 50 tons, but no matter how big it is, it should not work.
The upper limit of the power of a radiation imploding hydrogen bomb is almost infinite.
But the enhanced atomic bomb has one advantage, that is, it is better designed.Isn't it just layer by layer and layer by layer?Even India and Pakistan can do it.
In addition, this RDS-6C has another advantage, that is, it has been made into the shape of an aerial bomb, and it can be dropped by simply stuffing it into the stomach of a Tu-16 medium-range bomber. Ivy Mike" is still an experimental device connected to a cryogenic system.
……
At 8 am on August 12, RDS-10C was detonated.After the powerful flash, a huge mushroom cloud rose that the Soviets had never seen before.
The railway bridge 1 km away from the blast center was pushed away 200 meters, and the brick-and-earth building 4 km away from the blast center was knocked down by the shock wave. The equivalent measured by the instrument in real time was about 40 tons.
There was a bang at the Semipalatinsk nuclear test site, and the Soviet Pravda immediately sent a newsletter saying that the Soviet hydrogen bomb test was successful.
Anyway, whether it's puff pastry or a radiation imploding hydrogen bomb, no one is sure now.
