Title: Suguru Sato: Innovator in Electrical Generating Systems

Introduction

Suguru Sato is a notable inventor based in Ohbu, Japan, recognized for his contributions to electrical generating systems. With a total of seven patents to his name, Sato has made significant advancements in the field of automotive alternators and current generating systems.

Latest Patents

One of his latest patents is a current generating system with an output winding switching device. This invention features a first and a second full-wave rectifying network connected to generating coils of a generator, which generates alternating current. The switching device includes normally closed contacts that maintain voltage differences among the input terminals of the second full-wave rectifying network at zero. This allows the coils to function as a star-connected current generating winding while the contacts are closed. When the generator's rotational speed exceeds a predetermined value, the contacts open, enabling the coils to act as an independently generating winding, thus increasing the output current.

Another significant patent is an electrical generating system specifically designed for automotive use. This system prevents unusually high or low voltage output from an automotive-type alternator in case of a failure in the connection from the alternator rectifier output to the vehicle battery. It includes a connecting network that links an auxiliary alternator output terminal to the voltage sensing circuit, which controls the field current to the alternator, preventing excessive output voltages. Additionally, a further voltage sensing circuit is connected to the auxiliary terminal to provide limited energization for self-excitation of the generator when the vehicle engine starts.
