Title: Koichi Itoigawa: Innovator in Gyroscopic Technology
Introduction
Koichi Itoigawa is a prominent inventor based in Aichi-ken, Japan. He has made significant contributions to the field of gyroscopic technology, holding a total of 11 patents. His innovative designs and inventions have advanced the capabilities of various devices, particularly in the realm of acceleration switches and oscillation gyros.
Latest Patents
One of his latest patents is an oscillation gyro equipped with a thin PZT film. This oscillation gyro includes a stainless steel base member shaped as a quadratic prism, featuring through holes that extend in directions crossing at right angles. The design incorporates slide plates that form parallel plate portions, with a titanium film created by sputtering on the outer surfaces. A thin PZT film is applied to the entire outer surface of the titanium film, and pairs of aluminum electrode films are formed on the respective thin PZT films. The electrode films have a thickness of several micrometers and the same area. Additionally, pads are formed at the lower ends of the base member, which serve as fixed ends and connect to extension portions from the electrode film. Lead wires connected to the pads help suppress changes in the rigidity of the parallel plate portions caused by the connection of lead wires.
Another notable invention is a small acceleration switch designed to toggle between ON and OFF states based on the magnitude of acceleration applied. This switch features a first contact on a substrate and a movable part formed on a semiconductor chip through surface micromachining. The movable part includes a second contact that engages with the first contact when acceleration reaches a predetermined value.
