Title: Innovations of Yasuhumi Kawado

Introduction

Yasuhumi Kawado is a notable inventor based in Yamaguchi, Japan. He has made significant contributions to the field of sensor technology, holding a total of 7 patents. His work focuses on innovative methods for manufacturing sensors that enhance performance and reduce costs.

Latest Patents

One of his latest patents is a method of manufacturing a sensor having a magnetic film. This process involves crushing particles such as magnetic iron oxide to obtain minute magnetic particles, each not larger than 10 µm. These particles are mixed with a binding material like cobalt or nickel, and thermal spraying particles are produced from this mixture. The thermal spraying particles are then applied to components such as turbine shafts using a plasma spraying method to create a magnetic film.

Another significant patent is for a torque and rotating speed sensor. This invention features a pair of magnetic recording parts that are axially spaced on a rotating shaft. Magnetic heads are positioned to record and reproduce location signals from these parts. The torque of the rotating shaft is calculated based on the phase shift of the location signals, while the rotating speed is determined from the reproducing frequency of the signals. This design reduces the number of parts required for the sensor, making it more compact and cost-effective.
