Title: Ryoichi Yonezawa: Innovator in Malfunction Detection Technology

Introduction

Ryoichi Yonezawa is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of malfunction detection technology, holding a total of 3 patents. His work is particularly recognized for its accuracy and stability in detecting malfunctions in resolvers.

Latest Patents

One of Yonezawa's latest patents is a malfunction detection device for a resolver. This innovative device is designed to detect malfunctions in a resolver with high accuracy, even when the square sum values vary between normal and abnormal ranges. The device reads sine and cosine signals from the resolver. It determines whether a malfunction determination is prohibited based on these read values. If the determination is prohibited, the device accumulates a count value each time the test value falls outside the normal range. Once the count value reaches a specified threshold, the device concludes that the resolver is malfunctioning.
