The SR100 which opened the history of electronic valves
Fujikin has developed valves equipped with various sensors to meet customer's needs.
For example, the electronic valve "PRETRONIC® SR100" has a built-in potentiometer which detects the opening degree of the valve, and that opens and closes a valve by electromagnetic control is one of them. The time from fully open to fully closed is less than 0.6 seconds and it is possible to achieve the desired flow rate quickly and accurately.
This valve is accurately controlled by computer with technology developed by Fujikin, and a patent was applied for in 1978. It was the period when computers finally made their debut in the market in Japan. 6 years later in 1984, Japan's first internet experiments started by connecting Tokyo University, Tokyo Institute of Technology and Keio University, and another 14 years later in 1998, the rate of internet penetration in general households exceeded 10%.
The IoT era arrived with various things connected by the internet, and the concept of IoT was introduced to valves in this completely unimaginable era. Fujikin's breakthrough technology realized flow rate control of valves with computers by using wired analog signals.
Afterwards, in order to control valves accurately at high speed as computer processing speeds increased, various technology and devices were added to the structure and machining method of the valve, and Fujikin accomplished the evolution of its electronic valves.
Supporting semiconductor manufacturing and building the AI・IoT era with FCS®
40 years have passed since the development of the electronic valve, and now the world of semiconductor manufacturing is on the main stage.
Computers and mobile phones are a certainty, and even home appliances, automobiles and medical equipment in our daily lives are using semiconductors, and are an essential existence in our current lives and society. The future of the highly anticipated AI・IoT cannot be thought about without the evolution of semiconductors.
Every year, the number of elements integrated on to the chip of a semiconductor is rapidly increasing, and the width of the elaborate circuits on the latest semiconductor chips have now become even smaller than a virus. In semiconductor manufacturing which requires such precise technology, the "Flow Control System FCS®" series is used to skillfully control ultra-small amounts of gas to form extremely thin films and conduct the etching process.
By combining an ultra-precise electronic valve and pressure sensor for the flow rate controller, it provides the ability to accurately control the flow rate of the output gas even when there are pressure fluctuations in the supply gas, and it plays an important role in semiconductor manufacturing process.
Furthermore, Fujikin also developed the "Integrated Gas System IGS" which integrates multiple such equipment and can control a wide variety of gases in a small space. Fujikin's ultra-precise valves and systems contribute to the full-scale AI・IoT era through semiconductor manufacturing.
