Title: Innovations of Yu Iwai in Piezoelectric Technology
Introduction
Yu Iwai is a notable inventor based in Saitama, Japan, recognized for his contributions to the field of piezoelectric devices. With a total of five patents to his name, Iwai has made significant advancements in the production and design of piezoelectric vibrating devices. His work has implications for various applications, enhancing the performance and durability of these essential components.
Latest Patents
Iwai's latest patents focus on methods of producing piezoelectric vibrating devices. One of his exemplary processes involves creating piezoelectric vibrators with a tuning-fork configuration. This process includes preparing a flat plate of piezoelectric crystal material that exhibits anisotropic etching properties. A corrosion-resistant film is formed on both major surfaces of the piezoelectric material. A first coating of photoresist is applied to the surfaces of the corrosion-resistant film, followed by a lithographic exposure of the pattern of a piezoelectric vibrating device on one side of the piezoelectric plate. After developing the photoresist, the corrosion-resistant film is removed, allowing for the first etching of the piezoelectric material.
Another significant patent by Iwai involves piezoelectric devices that have improved impact resistance. This exemplary device features a lid plate, a chip plate with a tuning-fork type vibrating piece surrounded by an outer frame, and a package base that sandwiches the chip plate between the lid plate and package base. The tuning-fork type piezoelectric vibrating piece is supported by arms connected to the outer frame. A base-movement buffer extends from the inner edge surface of the outer frame toward the side edge of the base, with its height in the X-direction being proportional to the distance from the buffer to the point where the vibrating piece is coupled to the outer frame.
Career Highlights
Throughout his career, Yu Iwai has worked with prominent companies in the industry, including Nihon Dempa Kogyo Co., Ltd. and Nihon Dempa Kogyo, Ltd. His experience in these organizations has contributed to his expertise in piezoelectric technology and device manufacturing.
