Title: Hideo Ishida: Innovator in Vehicle Power Systems

Introduction

Hideo Ishida is a notable inventor based in Nagoya, Japan. He has made significant contributions to the field of vehicle power systems, holding a total of 3 patents. His innovative designs focus on enhancing the efficiency and reliability of power sources in vehicles.

Latest Patents

One of Ishida's latest patents is a power source apparatus for vehicles. This apparatus includes first and second switch means that control charging currents flowing from a rectifier of a generator to two batteries with equal open terminal voltages. The design features a third switch means that regulates the current through the generator's field winding. This third switch is activated based on the lower voltage of the two batteries, ensuring optimal charging. Additionally, the first and second switch means operate according to a duty factor determined by the voltage difference between the batteries. This innovative approach prioritizes charging the first battery when its voltage drops to a critical level necessary for starting the engine.

Another significant patent by Ishida is a lighting control apparatus for signal lights. This apparatus detects disconnections in signal lights, such as vehicle flashers, using a detecting resistor element that converts the ON current into a voltage signal. The voltage signal is then compared to a reference voltage to identify any discrepancies. If a disconnection is detected, the apparatus doubles the oscillation frequency of the signal light, providing a clear warning to the driver. The design of the detecting resistor element allows for precise adjustments to ensure accurate detection of any issues.
