Title: Keitsugu Nohara: Innovator in PTC Thermistor Technology

Introduction

Keitsugu Nohara is a notable inventor based in Akita, Japan. He has made significant contributions to the field of thermistor technology, particularly with his innovative PTC thermistor design. His work has implications for improving the efficiency and reliability of electronic components.

Latest Patents

Nohara holds a patent for a PTC thermistor that ensures ohmic contact between the thermistor body and an electrode. This invention prevents deterioration in the appearance of the thermistor, ultimately increasing production yields. The PTC thermistor features a body, a first electrode made of plated nickel with a thickness of 0.2 to 0.7 micrometers, and a second electrode primarily composed of a metal with low contact resistance. During the formation of the first electrode, moisture can enter the thermistor body, which can lead to defects during the baking process of the second electrode. By reducing the thickness of the first electrode, Nohara's design facilitates the outward discharge of moisture, thereby minimizing the occurrence of surface craters.
