Title: Michiyori Miura: Innovator in Magnetic and Elastic Surface Wave Technologies
Introduction
Michiyori Miura is a notable inventor based in Yokohama, Japan. He has made significant contributions to the fields of magnetic recording and elastic surface wave devices. With a total of 3 patents to his name, Miura's work has had a considerable impact on technology.
Latest Patents
One of Miura's latest patents is a thin-film-type magnetic head device. This device is designed for magnetically recording and reproducing signals in a magnetic recording medium. It features a lower magnetic layer, an insulating layer, a thin-film-type coil, and an upper magnetic layer, all formed sequentially on a substrate to create a magnetic circuit. The upper and lower magnetic layers partially abut each other, providing magnetic coupling. Additionally, at least one slit is formed in the region where the layers meet to suppress the generation of eddy currents.
Another significant patent is for an elastic surface wave device. This invention aims to eliminate disturbance signals caused by reflections from the unitary stem areas of comb-like electrodes in an interdigital transducer. The design includes at least one pair of partial edges on the edges of the unitary stem areas, with their positions differing by (2n+1)·λ/4 in the surface wave propagating direction. The lengths of the partial edges in each pair are equal, where n represents a non-negative integer and λ represents the wavelength of the elastic surface.
