Latest Patents

Tadashi Yamada holds a patent for a "Method and apparatus for controlling electromagnetic valve in industrial vehicle." This invention addresses the issue of preventing a solenoid from overheating due to an exciting current. The method involves a controller that commands a high-side driver to send a moving current to the solenoid, allowing the valve body of the electromagnetic valve to move to a connection position. Once in position, the controller then commands the high-side driver to send a maintaining current to keep the valve body in place. Both the moving and maintaining currents are pulse waves, with the duty ratio of the maintaining current being smaller than that of the moving current. This innovative approach enhances the performance and reliability of industrial vehicles.
