Title: The Innovations of Masao Kurisu

Introduction

Masao Kurisu is a notable inventor based in Anjo, Japan. He has made significant contributions to the field of engineering, particularly in the development of advanced valve timing devices. With a total of 3 patents to his name, Kurisu's work has had a considerable impact on automotive technology.

Latest Patents

One of his latest inventions is a valve timing adjusting device. This device features a second rotation body that includes a second sun gear part located inside a first rotation body. It is connected to a drive shaft or a driven shaft through the sprocket part, allowing it to rotate in correspondence with the drive or driven shaft. When the second rotation body contacts the sprocket part, its rotation relative to the first rotation body is restricted. Additionally, a planetary rotation body is involved, which includes a first planetary gear part engaged with the first sun gear part and a second planetary gear part engaged with the second sun gear part. This design enables a sun-and-planet motion that alters the phase of relative rotation between the two rotation bodies.

Another significant patent is the variable valve timing controller. This innovation allows an engine to utilize a variable valve timing device that transmits rotational force generated by a motor via a motor drive circuit to a cam shaft. This mechanism changes the rotational phase of the cam shaft relative to the crank shaft. The engine's ECU plays a crucial role by cooling the motor and motor drive circuit when a change in the rotational phase is detected, ensuring optimal performance.
