Title: Jun Toyoizumi: Innovator in Deterioration Regeneration Technologies

Introduction

Jun Toyoizumi is a notable inventor based in Makinohara, Japan. He has made significant contributions to the field of electrical connection technologies, particularly in the area of deterioration regeneration systems. With a total of 2 patents, Toyoizumi's work addresses critical issues related to electrical contacts and their performance.

Latest Patents

Toyoizumi's latest patents include a "Deterioration Regeneration System" and a "Deterioration Regeneration Method." The deterioration regeneration system features a pre-post regeneration determination part that assesses whether to execute a regeneration process for an electric contact. This process aims to restore connection performance that has deteriorated due to increased contact resistance. The system employs a second external action, which is larger than the first, to remove foreign objects affecting the electric contact.

His second patent, the "Deterioration Degree Diagnosis Device," includes a measurement unit and a diagnosis unit. The measurement unit evaluates the impedance related to contact resistance by measuring AC voltage and current between metal members. The diagnosis unit then determines the deterioration degree based on the reactance component value in the measured impedance.
