Title: Masayoshi Yamada: Innovator in Circuit Board Testing Technology

Introduction

Masayoshi Yamada is a notable inventor based in Shiga-cho, Japan. He has made significant contributions to the field of circuit board testing, holding 2 patents that showcase his innovative approach to technology.

Latest Patents

Yamada's latest patents include a circuit-based testing apparatus and method for testing a circuit board. This apparatus is designed to test the continuity and/or short-circuit of wirings formed on a circuit board. It features an electromagnetic wave irradiator that irradiates the first terminals of the wirings with an electromagnetic wave, allowing electrons to be discharged from these terminals through the photoelectric effect. The discharged electrons are then trapped by an electrode, which is electrically biased to have a higher potential than that of the second terminals of the wirings. This process causes an electric current to flow through the wirings via the electrode. The existence of open-circuit and/or short-circuit conditions in the wirings is determined based on the current flowing through them.
