Title: Innovations of Tatsuo Okamoto

Introduction

Tatsuo Okamoto is a notable inventor based in Nagaokakyo, Japan. He has made significant contributions to the field of semiconductor technology, holding a total of 6 patents. His work primarily focuses on motor driving control apparatuses and amplitude regulation circuits.

Latest Patents

One of his latest patents is a semiconductor integrated circuit that includes a motor driving control apparatus featuring an amplitude regulation circuit. This circuit incorporates a maximum detection circuit that outputs a maximum signal, MAX, which may be distorted during the transition of the highest-level signal. Additionally, it includes a minimum detection circuit that outputs a minimum signal, MIN, which also experiences distortion during the transition of the lowest-level signal. These distortions help reduce variations in the amplitude detection signal, AMP, which represents the difference between MAX and MIN. The amplitude regulation circuit amplifies rotor position signals based on the amplitude detection signal according to Automatic Gain Control (AGC), ensuring that the amplitudes of the signals remain constant while preserving sinusoidal waveforms.

Another significant patent by Okamoto is a motor driving control method and apparatus that also features an amplitude regulation circuit. Similar to his previous patent, this circuit includes maximum and minimum detection circuits that manage signal distortions effectively. The design aims to maintain consistent amplitudes of the signals while ensuring the integrity of the sinusoidal waveforms.
