Latest Patents

One of Masumitsu Ino's latest patents is focused on heat treatment by light irradiation. In this invention, a thin film of silicon is formed on an electrically insulating substrate, such as transparent quartz, through methods like glow discharge or chemical vapor deposition (CVD). Although the thin film typically lacks a monocrystalline structure, this method allows for the formation of silicon films over relatively large surface areas. The substrate, now coated with the thin film, is placed on a support plate, preferably made of silicon wafer. A blanket light irradiation is then performed using multiple tungsten halogen lamps. The light is preferentially absorbed by the silicon wafer, which heats up and transfers heat to the thin film through conduction. This process ensures that the thin film is uniformly heated, allowing for desired properties to be achieved, such as uniform monocrystallization.

Another significant patent by Ino is for a full-size optical sensor device that features improved driving means. This device includes a sensor array with numerous photoelectric conversion elements, divided into several groups. Each group contains multiple photoelectric conversion elements. The optical sensor is equipped with a driving circuit that selectively activates these elements based on an external control signal and the shifting operation of a shift register. The circuit includes multiple sets, each connecting a bit of the shift register to a group of photoelectric conversion elements, allowing for precise selection and control.
