Title: Kohji Aoki: Innovator in Motor Control Technology

Introduction

Kohji Aoki is a prominent inventor based in Nagoya, Japan. He has made significant contributions to the field of motor control technology, holding a total of 7 patents. His innovative designs focus on enhancing the efficiency and functionality of DC motors.

Latest Patents

One of Aoki's latest patents is a "Rotational pulse generating circuit for commutator DC motors." This invention features a filter device that eliminates noise from the motor, with a variable cutoff frequency depending on an external signal. Additionally, it includes a pulse shaping device that generates a ripple pulse indicative of the motor's rotational number by wave-shaping the output of the filter device. A clock generating device is also part of this invention, producing a clock signal based on the ripple pulse and the motor's rotational condition signal, which is fed back to the filter device to adjust its cutoff signal.

Another notable patent is the "Control device for movable member." This device utilizes a DC motor to establish position transfer for a movable member. It allows the movable member to return to a previously stored first position, even if it is currently at a second position, upon manipulating a switch. The motor pulse generating circuit in this invention generates a cutoff frequency that varies based on a ripple pulse frequency indicative of the motor's rotational number.
