Title: Innovations by Yoshihiro Yamashita: Pioneering Power Transmission Technologies

Introduction

Yoshihiro Yamashita, an influential inventor based in Anjo, Japan, has made significant contributions to the field of power transmission systems. With a total of four patents to his name, Yamashita's inventive work focuses on improving the efficiency and reliability of internal combustion engine systems.

Latest Patents

Yamashita’s latest patents include a groundbreaking design for a power transmission apparatus that enhances the performance of internal combustion engines. His innovative power transmission system transmits power from the engine to auxiliary devices through an endless transmitting member. Notably, before an engine start request is issued, the system actuates the first auxiliary device to position a tensioner pulley, which increases the tension of the member. This preemptive action ensures that the drive shaft of the engine is rotated quickly when the start request is made, resulting in a reduction of the time taken to start the engine.

In another significant patent, Yamashita developed a system where power from the engine's drive shaft is transmitted to auxiliary devices through a belt. This design features an auto-tensioner that adjusts the belt's tension effectively. A controller manages the rotation of the auxiliary device to loosen the belt as needed, maintaining an increased tension and preventing slippage on pulleys during engine startup. This innovation simplifies the operational demands on the auxiliary device, enhancing the overall efficiency of the power transmission process.
