As a modern industrial product, in its long process of development and improvement, with the continuous improvement of performance, it also brings about the increasing complexity of the product itself, from the early combination of optics and chemistry, and the subsequent continuous requirements for precision mechanical and electrical technical support, and later even the need for multidisciplinary technology intersection such as electronics and software.

The motor mentioned by Tu Zhenying belongs to the field of electrical technology, which is mainly used for the autofocus of the camera, which is generally installed inside the lens of the camera, and relies on the machine to provide a small amount of electrical energy to drive the motor, so as to realize the automatic focus of the camera.

Of course, the in-lens motor is just one of the many autofocus methods.

Autofocus technology originated in the sixties, and was first developed by Moving Energy and exhibited at the Cologne Fair in West Germany, followed by major camera giants in the seventies and eighties.

At this time, most of the autofocus technology used the fuselage drive scheme, for example, Minolta, which was in the limelight in the 80s, was the practitioner of the fuselage focus motor technology, and then Nikon and Pentax also followed suit, and they all used the built-in focus motor to achieve autofocus.

Why did Minolta, Nikon, and Pentax gain the upper hand in the 80s when autofocus technology was mature, and people can't help but ask, is it a dry meal for moving people at this time?

Obviously not, if you want to say the real reason, it is actually that at this time, Moving can choose a more radical, risky, and also superior solution in terms of performance: the lens has a built-in focusing motor.

The reason why the built-in focus motor of the lens is much more technically difficult than the built-in body is that the design of the lens is extremely compact, and almost everything is made around those few pieces of glass, so how can there be extra space for you to install the motor?

As an electromechanical product, the motor should reach the size of an ordinary No. 5 battery even if it is smaller, and this kind of thing is attached to the lens, so you can imagine what the hell it will look like.

Because of the size limitation of the focus motor, it is the best solution to install the motor on the body in order not to burden the lens.

Therefore, a large number of practical autofocus cameras in the 80s did this, such as Minolta, Nikon, and Pentax.

Compared with changing the installation place of the focus motor, Moving Energy chose to continue to bury its head in the focus motor slimming down the route, the traditional focus motor is the use of electromagnetic motor technology, due to the limitation of technical principles, it is impossible to make it smaller.

So, the moved energy that was obsessed with black technology pretended to be forced again, and this guy frantically got an ultrasonic motor out.

Before moving energy, ultrasonic motor has always existed only as a technical concept, although it has the advantages of small size, simple structure and large torque, but due to design problems, no one has ever made a physical object.

In the camera industry after 2000, when people chanted Suo Dafa's various black technologies, one thing could not be forgotten was that before Sony, it was actually moving to be able to be really obsessed with black technology, and this guy launched various technologies that really blinded people's eyes.

Now, Wang Zhengguo actually heard someone say that China is developing ultrasonic motors for camera lens autofocus, which is simply a thunderbolt from the sky, completely blinding people.

"What's the situation? You said that China is developing ultrasonic motors, and you have found Shuhang to invest?"

At this time, I can't take care of eating, if I can't figure things out quickly, I'm afraid I can't even sleep well today, so I have to disturb it, and it's not impossible to have a long talk all night.

This is an ultrasonic motor, to be able to break through this technology, Shuhang can definitely occupy a place in the domestic camera market, if it works well, it may even directly become the existence of setting industry standards.

"That's right, it's the ultrasonic motor, and the guy also said that it was designed specifically for the camera lens to be built-in, and now the detailed engineering design has been completed, but because there is no financial backing, it is impossible to actually build the product for testing and improvement. ”

Black technology like ultrasonic motors has no financial support, and there is already an engineering design plan, this Shudu Institute of Optics and Mechanics is really Ma Daha, such a promising good technology is not supported, it is really wasteful.

sighed: "It turned out to be a person from the Institute of Optics and Mechanics, no wonder, the people in this institute are engaged in black technology all day long, if you want to say that someone is developing ultrasonic motors, I believe it!"

Jokes, can be directly naked in the hall to do pure scientific research propaganda, the chief engineer changed careers to engage in adaptive optics, other departments research projects, often lithography machines, ballistic cameras and other things, this unit is fundamentally the main thing to do things.

The Shudu Institute of Optics and Mechanics is really good enough, and it is worthy of being able to develop into the largest research institute of the Chinese Academy of Sciences in the southwest region of the Republic of China.

"That's right, I remember that the man said in person that he happened to be a person from the ballistic camera department of the Institute of Optics and Mechanics, or because you introduced the CMOS laboratory of the School of Telecommunications Engineering to cooperate with the ballistic camera department, he only learned about our investment in the camera field from the CMOS laboratory, and then found us Shuhang Optics. ”

Tu Zhenying's words are completely puzzled by Wang Zhengguo, it turns out that in the final analysis, it is because of his own propaganda that this has attracted talents, yes, it seems that he will go out more in the future, and all major optical and optoelectronic units in China will go to see it, and no one can be missed.

Maybe there will be a surprise one day, who can say this?

"I see, what is the opinion of the company, what is the idea of this project?"

Considering that this is a direct formal channel to find Shuhang Optics, Wang Zhengguo does not plan to give his own views for the time being, he wants to hear how the company will treat this kind of door-to-door investment under normal circumstances, which can be regarded as an investigation of the decision-making ability of Shuhang Optics's senior management.

"That's right! I've been thinking about this project recently, whether to invest in him, and after determining the investment, how can we dig people into our Shuhang Optics, this kind of talent for camera design, we are now in great short supply of Shuhang. ”

Yes, it turns out that this is not just considering whether to support the ultrasonic motor project, this is directly preparing to poach people, it seems that Shuhang is indeed preparing to enter the camera industry, and this action force is really not covered.

"Two, all the dishes you ordered are ready, two meat and one vegetable, in addition, our store will send you another soup, use it slowly, and come often in the future!"

When it comes to the critical moment, the food in the store comes up again, I haven't smelled the food before, and I can still talk about business seriously, now.....

With a churning in the stomach, it seems that it is time to solve the physiological needs: "Come, let's eat first, and then talk in detail when we get back after eating, there will be more to talk about this later." ”
