Early the next morning, Ling Shizhe and Li Li came to the restaurant and found that Ling Zhigao had been in the restaurant for a while, with milk and a plate of fried poached eggs and a toast in front of him, and he was sitting on a chair wearing reading glasses and looking at the newspaper that had just arrived today.

"What's the news today?" Ling Shizhe sat next to him and asked.

"There is no big news, it's still the same, and the "Ming Pao" is criticizing the movement on the mainland, which has provoked the left, center and right factions in Hong Kong to fire at each other, and I am tired of watching it." After speaking, Ling Zhigao handed the newspaper in his hand to Ling Shizhe.

After taking the newspaper, I saw the cover of "Ming Pao", and there was a big headline on the front page of the editorial, "The Emperor Doesn't Like the Prince", predicting that Lin would not end well and would die without a place to be buried. It's no wonder that the left, center, and right will fight now, and the analysis of the whole article is as remote as it is reasonable. Ling Shizhe almost thought that this was an article written by a traverser, the above analysis was too accurate, and now he was indeed in full swing before he finished playing, and the time was not far away.

This old gentleman Zha is really not a peaceful lord, first offended Baodao, and now offended the north. Now that both sides have blacklisted him, this gentleman is not taking it seriously, and he is still trying his best to break the news, causing the left, center and right factions in Hong Kong to live in peace and fight each other into a pot of porridge.

Ling Shizhe didn't take a closer look, but just took a rough look, and after knowing which gentleman was right, he turned back and turned to the financial edition to see the report that it was Ambrera Company.

The report is a new PTC (PositiveTemperatureCoefficient) thermally ceramic resistor developed by Hong Kong Ambrera Industries a few months ago, which has been a great success in the market.

It is a kind of thermistor, composed of semiconductor ceramic materials, which is a typical semiconductor resistance with temperature sensitivity, when it exceeds a certain temperature (Curie temperature), its resistance value increases step with the increase of temperature.

"In August this year, the PTC thermally ceramic resistor developed by Ambrera Company has been a great success as soon as it is listed, and has been widely used in electric water heaters, electric kettles, refrigerators, microwave ovens, solar systems, freezers, photocopiers, etc., and has brought 30 million US dollars in global sales to Ambrella, and Ambrera has made a lot of profits. It has become another ceramic money-making weapon after the new mutton fat white jade ceramics. ”

Seeing this report, Ling Shizhe shook his head. "Why shake your head, your company's newly developed ceramics are selling well, you should be happy!" Ling Zhigao asked.

The industrial technology reported by the financial section of Ming Pao is too unprofessional compared to the political section of his own front-page report, and there are two kinds of thermistors researched by Ambrera, one is the PTC positive temperature coefficient thermistor reported above, and the other is the NTC (negative temperature coefficient) thermistor. But they only said the former, not the latter, but many of the above product applications are indispensable to the use of NTC, and many of the above are confused. ”

Seeing the confusion of Ling Zhigao and Li Li, Ling Shizhe gave them popular science: "NTC/PTC are both thermistors. PTC refers to the temperature coefficient thermistor; NTC refers to Negative Temperature Coefficient Thermistor; PTC is used for overload, overcurrent, overheat, and over-temperature protection, such as overcurrent, overload, and short-circuit protection for chargers, air conditioners, switching power supplies, degaussing circuits for color TVs, and starting circuits for refrigerator compressors. NTC is generally used for temperature measurement and control and suppression of inrush current, such as mobile phone battery protection and circuit protection of office automation equipment, electronic thermometers, air conditioners, refrigerators, water dispensers and other household appliances. You see, Ming Pao confuses these two types of citations. ”

Ling Zhigao and Li Li were dizzy when they heard it, and they felt that these two things were similar in application. Yes, not professionals, ordinary people are indeed easy to get dizzy, which is why Ling Shizhe said that "Ming Pao" is unprofessional. You just need to remember that PTC can be used for current protection in the circuit, and NTC is mainly for the suppression of switching inrush current. They also have a common role of temperature sensing and detection, just do it.

PTC is also studying the absorption of switch surges, but it is not too good to match the light, and NTC is generally used.

Zhang Yuzhen saw Ling Zhigao and Li Li on the side, and the more she listened, the more confused she became, knowing that Ling Shizhe's old mistake had been committed again. Ling Shizhe likes to deliberately make things mysterious, make customers stunned, make customers think that it is a very high-tech thing, give them a high, big, and upward influence and then bargain hard, and finally maximize benefits. In Hong Kong, Macao, Taiwan, and Southeast Asia, many businessmen fell for Ling Shizhe's way, and finally sold his goods at a high price.

But are these products really expensive? To tell you, the price is really not low, taking PTC as an example, it is Philips scientists and others in 1955 for the first time to discover the properties of PTC materials, its discovery for Philips to become the king of small household appliances in the world in the future laid a solid foundation.

As for NTC, he discovered it a little earlier, in 1834, scientists first discovered that silver sulfide has the characteristics of a negative temperature coefficient. In 1930, scientists discovered that cuprous oxide also has the performance of negative temperature coefficient, and successfully applied it to the temperature compensation circuit of aviation instruments. Subsequently, due to the continuous development of transistor technology, the research of thermistors has also made significant progress, and the first NTC thermistor was developed in 1960, and then NTC has been widely used in temperature measurement, temperature control, temperature compensation, etc.

In later generations, PTC and NTC have made many major technological breakthroughs after decades of research, the theory is becoming more and more mature, the application range is getting larger and larger, the process is becoming more and more mature, and the manufacturing cost is getting lower and lower, so the price is also very cheap in price, of course, there are also expensive, but the price is generally not high in the field of ordinary household appliances and consumer electronics.

It's different in this era, what era is it now? At the end of 70 and the beginning of 71, PTC and NTC were still a novelty, and people's research on them was still basically in the early stages, and the scope of application was limited, so the price was naturally high. But what kind of person is Ling Shizhe, he crossed over, he brought the extremely mature TBC and NTC thermal sensitive technology to this era, just the production cost instantly killed all the thermistor companies in the world, Ambrera company's thermistor varieties are much more than other companies, and the application range is naturally wider than the market of other companies.

How profitable? The price of one of the cheapest thermal sensitive resistors is 3 US dollars, the profit is 500%, others still think it is very cheap, when Li Li reported the profit margin of thermal sensitive ceramics, Ling Zhigao and Zhang Yuzhen were both stunned, they couldn't imagine that a small thermal sensitive resistor actually contained such a big profit, and the money grabbing was not so powerful. "Is it really so profitable for high technology?" Ling Zhigao has been engaged in factories, and never thought that a high-tech factory could have such a large profit margin. The factories he used to build did not have any technical content, and he did it with a speculative mentality.

"Li Li is right, she is my help, responsible for the financial aspect, PTC and NTC two kinds of thermistor ceramic resistors how profitable, she can't be clearer." Ling Shizhe said lightly.

Ling Zhigao suddenly had a feeling that he had lived in vain in his life, he worked hard to get acquainted with senior officials of the Hong Kong government everywhere, and pulled relationships everywhere, and finally successfully developed a piece of real estate, with a gross profit of up to 50%, which was still the result of great luck, which is usually 35%; Have you ever opened a factory with such a high profit before, generally 5% of the gross profit, and there is still a lot of competition between them; His own son opens a factory casually with 500% profits, this person has to die more than others, and the goods have to be thrown away!

"Old Seven, what do you think of me opening such a high-tech factory?"

Ling Shizhe saw Ling Zhigao's appearance and knew that his speculative mentality had germinated again, he was either speculating or speculating all his life, when did he feel at ease and engaged in industry, that is, he opened a factory with a speculative mentality, and he didn't seriously consider how the factory should go in the future. If you want him to build a laboratory, engage in scientific research for ten years, and wait for the last ten or twenty years, and make huge profits after success, he definitely does not have the patience, not counting the risk of all the money for development failure. To put it bluntly, Ling Zhigao is just a speculative gambler. This is also the mentality of most Hong Kong enterprises now, so they can only play in the end finance, real estate, entrepot trade and other industries with little investment, quick results, and no technical content.

Even as long as you have a strong relationship and a good enough brain, you can have an empty glove white wolf, and the real estate he develops is not like this. I took land from the government, went to the bank to get a mortgage to build a house, and I got land from the government, and there was a loan...... Typical of a white wolf with empty gloves.

"And what kind of high-tech do you want to drive?" Ling Shizhe looked at Ling Zhigao and asked with a smile.

"Oh, what do you think of a dead old man, can you run a high-tech factory? Is that something that people can do casually? You just see Shizhe making money, have you seen him invest a lot of money into the laboratory every year, all tens of millions of dollars, this is dollars! Not Hong Kong dollars. Can you vote? Before you can make money, you will first throw yourself to death, no! Zhang Yuzhen snapped.

She and Ling Zhigao have known him very well for decades, and when she heard that the gross profit margin of the thermistor produced by her son's company was 500%, she saw the old man's eyes shining, and knew that he wanted to get involved. It's a pity that he mixed it?

A few years ago, when the son made a new type of mutton fat white jade ceramics, there were many Hong Kong, Taiwan and Southeast Asian manufacturers who wanted to make his ceramic varieties, what was the result, not a sound could be heard, they also dug up their son's technical personnel and what about it, or even a sound could not be heard, and finally Ling Shizhe's company sued them for infringement, and instantly made their chickens and eggs beat, I don't know how many people went bankrupt and jumped off the building, many people asked friends to intercede, he was just unmoved, and his son's heart was ruthless. Now in the whole of Hong Kong, Taiwan and Southeast Asia, except for the Zhaofeng Ceramics that produces ceramic sanitary ware and the son's ceramic factory, it is not a gluttony.

Now the mutton fat white jade ceramics and the new enamel porcelain developed on this basis have been the absolute field of Ambrera company, and no one in the world, including Japan and Southeast Asia, dares to touch it. Under the complete patent barrier established by Ling Shizhe and the butcher's knife of the patent stick, the result of their touch is a dead end.

Hearing his wife's reminder, Ling Zhigao came to his senses, stopped thinking about the high-tech factory, and began to eat under Zhang Yuzhen's service.

Seeing his mother and a maid feeding Ling Zhigao spoonful by spoonful, Ling Shizhe turned his head to look at Li Li. Li Li knew his dirty thoughts, and reached out to twist his waist vigorously, ah! Ling Shizhe screamed.

"What are you doing, you haven't eaten yet." Zhang Yuzhen looked at Ling Shizhe and said angrily.

"Eat, eat, eat. If you don't do it, don't do it, why are you so fierce. Ling Shizhe complained quietly. It's a pity that his words were still heard by someone, and his waist was twisted again.

Yes! Another scream, Ling Zhigao, Zhang Yuzhen turned his head to look at him, Ling Shizhe didn't dare to eat in a hurry when he was funny, and his waist was blue again.
