Title: Hiromitsu Nakamizo and His Rotation Sensor Patent

Introduction

Hiromitsu Nakamizo is an inventor associated with Sony Corporation in Tokyo, Japan. His patent work includes a rotation sensor designed to detect both incremental rotation and angular position while reducing electromagnetic interference between its sensing circuits.

Latest Patents

Nakamizo is credited with 1 patent: “Rotation Sensor with Co-Planar Velocity and Position Responsive Elements.” The invention combines circuitry for sensing small rotational movements with circuitry for detecting a predetermined angular orientation. Its design places the full-ring rotation-sensing circuit and the narrower angular-position circuit at different radial positions, preventing them from overlapping radially.

Corresponding magnetic rings use alternating polarities to induce electrical signals as the circuits rotate. The patent also describes circuit connections arranged to reduce interference and improve their alignment with magnetic flux. Together, these features support the sensor’s ability to provide rotation and position signals through a shared electrical terminal.

Career Highlights

Nakamizo’s documented patent contribution reflects work on sensor design and the integration of rotational and angular-position detection. The patent identifies Sony Corporation as the company associated with his work.
