Introduction

Kazuhiko Koga is a notable inventor based in Toyohashi, Japan. He has made significant contributions to the field of electronic devices, holding a total of 4 patents. His work focuses on enhancing the performance and reliability of electronic components, particularly in relation to pressure detection and wire fatigue.

Latest Patents

One of Koga's latest patents is for a structure of an electronic device that provides decreased fatigue of wire. This invention involves a semiconductor pressure sensor that features a buffer within a resinous casing. The terminals extend through the casing and connect electrically with an electronic element mounted on the casing through wires. The buffer is made from a material with a smaller coefficient of thermal expansion than that of the casing body. This design minimizes undesirable movement of the terminals, which can lead to wire fatigue due to temperature changes. Consequently, it helps maintain the mechanical strength of the wires during thermal cycling.

Another significant patent by Koga is for a pressure detection apparatus that includes first and second cases defining a pressure detection chamber between them. The manufacturing method involves fitting an end portion of the first case into an opening of the second case, filling the defined space with adhesive, and hardening it. This process reduces variations in the volume of the sealed pressure detection chamber, leading to decreased output variations.
