Title: Kazuhiro Okuda: Innovator in Piezoelectric Technology
Introduction
Kazuhiro Okuda is a prominent inventor based in Osaka, Japan. He has made significant contributions to the field of piezoelectric technology, holding a total of 4 patents. His work focuses on enhancing the performance and efficiency of electronic components.
Latest Patents
One of Okuda's latest patents is for a common mode choke coil and its manufacturing method. The objective of this invention is to provide a common mode choke coil with high impedance and minimal variation. This design includes a magnetic core with a winding core part and a pair of flange parts on opposite ends. External electrodes are formed on each flange part, and a pair of windings are wound on the winding core part, with each end connected to one of the external electrodes. Additionally, a magnetic plate is adhered to the flange parts, featuring specific surface roughness characteristics to enhance performance.
Another notable patent involves a piezoelectric porcelain composition, which includes three components: Pb(ZnNb)O, PbTiO, and PbZrO. This composition has a basic formula of Pb(ZnNb)ZrTiO, where the values of x, y, and z fall within a specified range. It exhibits excellent piezoelectric characteristics and heat resistance, with a low sintering temperature of about 900°C. The coupling coefficient Kp is not less than 0.50, and the Curie temperature is not lower than 300°C. This innovation allows for the use of inexpensive materials, such as silver and silver-palladium alloys, in the internal electrodes of piezoelectric devices.
