Title: Masashi Nakayama: Innovator in Electrical Engineering
Introduction
Masashi Nakayama is a notable inventor based in Shizuoka-ken, Japan. He has made significant contributions to the field of electrical engineering, particularly in the development of innovative devices and systems. With a total of 5 patents to his name, Nakayama has demonstrated a commitment to advancing technology.
Latest Patents
One of Nakayama's latest patents is a wire harness that includes a relay box designed with a frame to which either a mechanical relay cassette or a communication-function-provided relay cassette can be replaceably attached. This wire harness also features a junction connector that has a space for installing a communication module, along with a junction box equipped with a microcomputer that operates a communication function optionally.
Another significant patent is for an overcurrent protection device and system. This invention provides time differences among the timings for executing retry operations among multiple overcurrent protection devices connected to a common power supply. When the battery voltage drops to a threshold value after an FET of an IC circuit is activated, all FETs of the respective IC circuits are turned off. The system clocks the time until the battery voltage decreases below the threshold. If this time is less than 400 microseconds, the count value is incremented. The FETs are then turned on again after a randomly set standby time. If the count value reaches 7, the FET of the IC circuit remains in the off state, allowing only the load-driving circuit experiencing a dead short to stop while continuing the operation of other circuits.
