Title: The Innovative Contributions of Toshitaka Yamada
Introduction
Toshitaka Yamada is a prominent inventor based in Nagoya, Japan, known for his significant contributions to the field of engineering. With a total of 17 patents to his name, Yamada has made remarkable advancements, particularly in the area of turbocharging technology.
Latest Patents
One of Yamada's latest patents is a rotational speed and position detector for superchargers. This invention involves a motor-assisted turbocharger that includes a turbine driven by exhaust gas energy, a compressor rotated by the turbine, and a rotary electric machine that assists the compressor's rotation. These components are interconnected by a common rotating shaft. A polygon nut with a magnetic member is attached to the rotating shaft's axial end, facing a fixed magnetic sensor. The magnetic field created between the magnetic member and the sensor changes with the rotation of the shaft, allowing for the detection of the compressor's rotational speed and position. The turbocharger's operation is electronically controlled based on these detected parameters.
Another notable patent is a rotation detector using a magnetoresistance element positioned in proximity to a toothed gear rotated by an engine. This element detects the angular position of the gear, even before the engine starts, by utilizing a magnetic field supplied from a bias magnet. An additional magnetoresistance element can be used to determine the exact angle of the gear once it begins to rotate.
