Title: Innovations of Hiroki Takahashi

Introduction

Hiroki Takahashi is a prominent inventor based in Kariya, Japan. He has made significant contributions to the field of engineering, particularly in the automotive sector. With a total of 15 patents to his name, Takahashi has developed innovative technologies that enhance vehicle performance and efficiency.

Latest Patents

One of his latest inventions is a valve timing adjustment device that utilizes Hall sensors to output measurement signals. These signals change according to the rotation position of an electric motor. A rotation signal generator within the drive circuit produces both a rotation speed signal and a rotation direction signal based on these measurement signals. Additionally, a control circuit generates control signals for the electric motor according to the edges of the output signals from the rotation signal generator. A signal corrector is also included, which adjusts for any excess or shortage of the signal edge when starting the electric motor, based on specific voltage levels and the rotation direction at the time of power source activation.

Another notable patent is also a valve timing adjustment device, where a drive-side rotor rotates synchronously with a crankshaft while a driven-side rotor is integrated with a camshaft. This invention features an internal gear section at the driven-side rotor and an Oldham coupling that synchronizes the rotation of the driven and drive Oldham flanges while allowing for eccentricity. The design ensures optimal performance and reliability in engine operations.
