Title: Innovations of Yoshihiro Nakamura
Introduction
Yoshihiro Nakamura is a notable inventor based in Gifu, Japan. He has made significant contributions to the field of electrical engineering, particularly in the development of safety mechanisms for electrical devices.
Latest Patents
Nakamura holds a patent for a sign lamp lighting transformer with protective functions. This innovative device includes an abnormality detection circuit that identifies issues related to ground faults in the secondary winding circuitry of the transformer. It also detects non-grounding faults of the transformer assembly casing and false connections of the AC power source in reverse polarity. The interrupter circuit is designed to turn off a switch in response to any detected abnormalities, effectively interrupting the supply of AC power to the transformer. When the power supply is interrupted, the switch connects to a restart circuit, allowing a charging current to flow to a capacitor. This capacitor is connected in series within the drive current path of a drive circuit, with a time delay of approximately 0.5 to 1.0 seconds determined by the delay circuit. The charging current activates a restoring circuit, which temporarily controls the interrupter circuit to restore the switch to its "on" condition only once.
