Title: Shuuichi Kokubun: Innovator in Vehicle Charging Technology
Introduction
Shuuichi Kokubun is a notable inventor based in Naka-machi, Japan. He has made significant contributions to the field of vehicle charging technology, holding three patents that showcase his innovative spirit and technical expertise.
Latest Patents
One of his latest patents is a "Vehicle Use Charging Generator." This invention provides a vehicular charging and generating system capable of issuing an alarm to a driver even when a failure occurs in the rectifying apparatus. The failure detecting means issues an alarm when the difference between the output voltage of generated voltage detecting means and the output voltage of average phase voltage detecting means exceeds a first difference voltage or falls below a second difference voltage, both set when no failure is present in the rectifying element. Another significant patent is the "Control Device for Motor Vehicle Use Charging Generator." This control device takes into account the relationship between field currents flowing through field windings of charging generators with different generation powers and output currents. The field current is increased instantly at the time of loading, and the amount of increase is controlled to be proportional to the field current before loading. This innovation can be utilized for charging generators with varying power generation capacities, effectively reducing battery voltage drops when switching in a motor vehicle electric load.
