Title: Shigeru Yasuda: Innovator in Disk Player Technology
Introduction
Shigeru Yasuda is a notable inventor based in Tokorozawa, Japan. He has made significant contributions to the field of disk player technology, holding a total of 9 patents. His innovative designs and methods have enhanced the functionality and performance of disk playing apparatuses.
Latest Patents
Among his latest patents, Yasuda has developed an "Apparatus for controlling rotation of disk player." This apparatus includes a lock detection unit, a memory unit, a comparison unit, and a control unit. When the lock detection unit identifies a lock state in the time base servo loop, it stores a voltage corresponding to the frequency of a read RF signal in the memory unit. The control unit then detects significant deviations in the spindle motor's rotation velocity and adjusts the motor's speed based on comparisons made with the stored voltage.
Another notable patent is the "Method for playback of a portion of a recorded disk played before." This method allows a disk playing apparatus to reproduce the last portion of a recording by memorizing the address data of the first recording position. When a last scene reproduction command is issued, the apparatus starts playback from a position before the first recording position, preventing any discontinuity in the program.
