Title: Innovations of Yoshihiro Satou
Introduction
Yoshihiro Satou is a notable inventor based in Chiyoda, Japan. He has made significant contributions to the field of disk drive technology, holding 2 patents that showcase his innovative approach to engineering challenges. His work primarily focuses on improving the reliability and efficiency of disk drives.
Latest Patents
One of Satou's latest patents is for a disk drive with an unbalance correcting mechanism. This invention eliminates the need for running-in to stabilize changes in the correcting function caused by sliding between balls and a rolling groove. It prevents immobility and straying of balls, utilizing a unit mechanism assembled with 12 balls treated with heptadecafluorodecyltrimethoxysilane. The turntable is plated with a chemical nickel coating containing phosphorus and boron, achieving a thickness of 5 µm. Additionally, the design incorporates a recess in the sidewall of the rolling groove to extend the service life of the correcting function.
Another significant patent is for a disk type reproducing apparatus and revolution control method. This invention increases the number of revolutions of a disk to a level higher than the resonance frequency of the rotation support system at startup. Subsequently, servo control for a pickup actuator is activated to read information from the disk. This method enhances the reproducibility of disk unbalance correction, improves apparatus reliability, and allows for high-speed spinning of the disk without generating vibrations or noise.
