Title: Satoshi Hitomi: Innovator in Rotational Speed Control Systems
Introduction
Satoshi Hitomi is a notable inventor based in Shizuoka, Japan. He has made significant contributions to the field of internal combustion engine technology. His innovative approach has led to the development of a unique rotational speed control system.
Latest Patents
Satoshi Hitomi holds a patent for a rotational speed control system for internal combustion engines. This system is designed to prevent dead time or dead sections during the control of engine rotational speed. The technology utilizes an integrating circuit controlled by a comparator that compares a rotational speed detection signal with a target rotational speed setting signal. This process generates an integral voltage that varies based on the relationship between the detection signal and the target setting. The comparison of this integral voltage with a sawtooth signal voltage results in a pulse signal subjected to pulse width modulation. This pulse signal is then used to control the actuator driving circuit, ensuring efficient on-off control of the drive current. Additionally, voltage limiting circuits are integrated to maintain the variation of the integral voltage within a specific amplitude range, effectively eliminating dead time or dead sections.
