Chapter 378: Sold

Wang Jishan frowned and thought for a long time, only to think that this person was vaguely familiar, but he couldn't remember when and where he saw him, but when he saw this person enter the door, he called himself "Pharaoh". Quite familiar.
Seeing that Wang Jishan hesitated, the man readily introduced himself: "Lao Wang, have you forgotten? I am Liu Weidong from Fengyun Factory. When you came to our factory to support you, it was the dormitory I arranged for you. "
When he said this, Wang Jishan finally remembered, and hurriedly stepped forward and held this person’s hand repeatedly apologizing:
I’m sorry, this man is old and his memory is not good. Yes, I will go in 60 years. Fengyun Factory was arranged by your old Liu. At that time, you were still a young man who had just started working. Oh, it's been more than 20 years since this moment."
Since he is an old friend, Wang Jishan immediately became more enthusiastic, took Liu Weidong's hand and greeted a few words, and then asked, "Lao Liu, what's the matter with you this time? And, this one again?"
Liu Weidong hurriedly introduced: "Oh, let me introduce you. This is Section Chief Fan Dingpan of the General Assembly Technology Department. We are here this time, specifically for your help."
Wang Jishan hurriedly shook hands with this one, and while greeted them to sit down and pour a glass of water for both of them, he rubbed his hands embarrassedly and apologized: "Look, you two came suddenly, I am not here. What preparation, not even tea."
Staff General Fan didn't care about this, but said with a smile: "I heard Director Liu on the way here, saying that Professor Wang doesn't like anything else. It's just a good wine, and it must be a high-quality white wine. If so, I’ll bring you some Erguotou from Beijing."
Wang Jishan said with a smile: "Really, it's been over 20 years. Old Liu still remembers my hobby. By the way, Old Liu, I haven't seen you in these years. You have become the director of 7055. ?congratulations!"
Liu Weidong hurriedly waved his hand and said, "Deputy, deputy, haha." But the triumphant look on his face couldn't hide it.
Also, the 7055 Factory, also known as the Henan Fengyun Equipment Factory, is a state-owned factory with a staff of more than 1,000 people. The main products are all kinds of power storage products, that is, batteries. Its product line includes various Class dry batteries, lead-acid batteries and nickel-cadmium batteries, etc., are China's leading backbone enterprises in the battery field.
The factory was built in 1960, and when the factory was built, Wang Jishan was one of the professional construction aid personnel transferred from all over the country. Some of those elderly people eventually stayed there to become the technical backbone of the factory, but After completing his work, Wang Jishan returned to Harbin Institute of Technology to continue teaching in accordance with the organizational arrangements.
To be the director of such a large factory, even if it is only a deputy, at Liu Weidong's age, it can be called "prosperous career", so it is natural to be a little proud. Wang Jishan didn't think about it either, but continued to ask, "What can I do for you? I remember, your technical strength is still quite strong?"
The one who answered him was General Staff Fan. He said,
That’s the case. Recently, our Technology Department hosted the upgrade research and development work of a certain type of main battle equipment. During the research and development process, it was discovered that the original equipment of this type of equipment had lead acid. The battery has the problem of too large weight and volume, and too long charging time. Therefore, after the demonstration, everyone agreed that the power supply part of this equipment should be upgraded and selected for lighter weight and higher energy density nickel-cadmium The battery is the goal."
Wang Jishan replied: "This is a good thing. Compared with lead-acid batteries, nickel-cadmium batteries can at least double the energy density, but the weight is only one-half of it or even lighter, and there are also faster charging speeds. The characteristics, considering only from the perspective of the battery, such a change should be reasonable."
Staff General Fan continued:
Yes, so we have drawn up the technical indicators and presented them to the battery production plant of the equipment, which is the 7055 plant where Director Liu is located. I hope they can develop a suitable one within the specified time. battery."
Wang Jishan said: "The 7055 factory is indeed the leading company in our Huaxia battery industry. It should be okay to hand it over to them?"
Staff General Fan said: "We originally thought so, but after more than one year of continuous technical research, the 7055 factory has not been able to completely solve the various problems of this battery, whether it is weight, energy storage density and instantaneous output. The maximum withstand current is far from the design index, and it has seriously affected the overall process of equipment research and development, so..."
"So, I was cheeky and came to your old Wang for help." Liu Weidong continued.
"Oh? So, then, Staff Fan, can you show me the technical indicators you proposed?"
"Of course we can. We are here for this. However, this is classified technical information, so after you read it, you must not pass it on." As staff member Fan answered, he opened his own pocket and read it. He pulled out a piece of paper and handed it to Wang Jishan.
Wang Jishan replied, "I know discipline, please rest assured, Staff Fan." He took the piece of paper.
The technical indicators were cut to the end, leaving simple target parameters. This is also one of the confidentiality principles. Wang Jishan lowered his head and calculated it carefully. He felt that this nickel-cadmium battery with a rated output voltage of 30 volts was not too much. Difficult, at least, after applying the new technology he just completed, the main technical parameters such as energy storage density, instantaneous output maximum withstand current, continuous output current, etc. should all meet the requirements, and individual parameters such as fast charging time even have some It may be greatly exceeded. Of course, it is really not easy to achieve this technical parameter if only according to the previous preparation process.
So, since it is a major event involving China's equipment, it is also necessary to make some contributions within its capacity.
Thinking about this, he raised his head and smiled: "Old Liu, and Staff Fan, it's a coincidence that you came here. I just developed a new production process that can compare the energy storage density of nickel-cadmium batteries. The current method has increased by 40%..."
At this point, he suddenly remembered something, and couldn't help but silence.
Liu Weidong hadn't heard the hesitation in Wang Jishan's words, and he couldn't help but exclaimed: "Counselor Fan, do you think Professor Wang has a way? Sure enough, our trip was not in vain!"
Fan Dingpan also smiled and asked with a smile: "Professor Wang, how far is your improved technology now? Can it be put into practical use?"
Wang Jishan didn't know how to answer for a while, and he hesitated for a while before he said: "The research and development has been completed, and the laboratory verification has been completed. It's just that..."
Liu Weidong urged: "Just what? Is there any technical problem? It doesn't matter, I can arrange for the technicians in our factory to come to you immediately and try to solve it as soon as possible."
Wang Jishan's face was reddened, and he hesitated: "There is no problem technically, but this technology has already been sold."
Hearing Wang Jishan’s answer, Fan Dingpan and Liu Weidong couldn’t help but look at each other. In the end, Fan Dingpan asked,
Sold it? Whom did you sell it to? Moreover, technology is not a real thing, even if it’s sold, you don’t know everything. Huh? Can't it be copied?"
Wang Jishan had no choice but to reply: "It was sold to a Xiangjiang company, and according to the contract, they already have all the intellectual property rights. If I leak this technology to anyone, it will be considered a breach of contract and infringement. Our school has to lose a lot of money."
"What? Xiangjiang Company?!"
