Title: Masakazu Yoshio: Innovator in Piezoelectric Technology
Introduction
Masakazu Yoshio is a prominent inventor based in Toyama-ken, Japan. He has made significant contributions to the field of piezoelectric technology, holding a total of 6 patents. His work focuses on enhancing the performance and efficiency of piezoelectric resonators.
Latest Patents
Yoshio's latest patents include a piezoelectric resonator and a method for producing the same. This invention aims to reduce frequency variations caused by changes in frequency constants and suppress unnecessary vibrations. The piezoelectric resonator features vibrating electrodes that face each other, formed on two major surfaces of a piezoelectric substrate. The substrate has a constant thickness, but its frequency constant exhibits a gradient in the surface direction. By designing the vibrating electrodes with a gradient thickness, unnecessary in-band vibrations are minimized, leading to reduced frequency variations.
Another notable patent is the energy trap type piezoelectric resonator component. This component utilizes a third overtone of thickness longitudinal vibration. It includes a piezoelectric substrate and first and second vibrating electrodes, which are elliptical in shape and arranged to face each other. The design allows for a compact resonator that effectively controls the fundamental wave of thickness longitudinal vibration while meeting various frequency requirements.
