Introduction

Masayuki Ishitaki is a notable inventor based in Nagaokakyo, Japan. He has made significant contributions to the field of acoustic wave devices, showcasing his expertise through innovative patents. His work is particularly recognized for its application in advanced technology.

Latest Patents

Ishitaki holds a patent for an "Acoustic wave device including multiple regions with multiple acoustic velocities." This invention features an interdigital transducer electrode situated on a piezoelectric film. The design includes a first busbar, a second busbar, multiple first electrode fingers, and multiple second electrode fingers. The overlapping of the first and second electrode fingers occurs in a region where an acoustic wave propagates. This region consists of a central area, a first edge region between the central region and the first busbar, and a second edge region between the central region and the second busbar. Notably, the acoustic velocity in the edge regions is lower than that in the central region, while the busbar region exhibits a higher acoustic velocity than the central region. This innovative design enhances the functionality of acoustic wave devices.
