Introduction

Yasuhiro Matsufuji is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of magnetic sensor technology, holding a total of 5 patents. His innovative work has advanced the capabilities of inspection devices and flaw detection systems.

Latest Patents

Matsufuji's latest patents include a sensitivity calibration method, an inspection device, and a magnetic sensor group. The inspection device features multiple magnetic sensors, wiring for calibration, and a controller. The wiring for calibration is strategically arranged relative to the magnetically sensitive portions of each sensor. The controller is designed to obtain initial output values from the sensors and applies a current to the calibration wiring before the electrical steel sheet passes the sensors. This process allows for accurate measurement corrections based on the outputs obtained before and after the calibration.

Another notable patent is the leakage-flux flaw detection device. This device includes several leakage-flux flaw detectors positioned away from the steel strip, arranged across its width. Each detector features a rotating disk that faces the surface of the steel strip and includes multiple defect detection heads. These heads perform direct-current magnetization and detect leakage flux from linear defects, with some heads having unique inclination angles to enhance detection accuracy.
