Title: **Masayoshi Minakuchi: Innovator in Electrical Steel Technology**

Introduction

Masayoshi Minakuchi is a prominent inventor based in Kitakyushu, Japan, known for his significant contributions to the field of electrical steel technology. With a total of two patents to his name, Minakuchi has developed innovative processes that enhance the performance and characteristics of electrical steel sheets, which are crucial in various applications, including transformers and electrical components.

Latest Patents

The first of Minakuchi's latest patents is titled "Process for production of oriented electrical steel sheet." This invention focuses on a method where a slab for an electrical steel sheet is heated at a temperature of 1280°C or below and subsequently hot-rolled. The process involves cold-rolling the hot-rolled steel sheet once or at least twice, with intermediate annealing between rollings. Following cold-rolling, the steel sheet undergoes decarburization and nitriding to establish an inhibitor. By measuring specific parameters during the nitriding treatment, Minakuchi's method ensures optimal grain characteristics in the final product.

His second patent, "Process for preparation of grain-oriented electrical steel sheet," employs an improved technique for heating an electrical steel slab at lower temperatures. This process results in a grain-oriented electrical steel sheet with outstanding magnetic and film properties. The slab used in this method is composed of carefully balanced constituents, ensuring maximum efficiency during the heat treatment and nitriding stages.
