Title: Shigeru Kawase: Innovator in Optical and Magnetic Technologies
Introduction
Shigeru Kawase is a prominent inventor based in Yokohama, Japan. He has made significant contributions to the fields of optical and magnetic technologies. With a total of 6 patents to his name, Kawase has developed innovative solutions that enhance the functionality of optical disc apparatuses and magnetic reproducing systems.
Latest Patents
Kawase's latest patents include an optical disc apparatus and an optical-pickup movement control method. This invention involves emitting a light beam to an optical disc from an optical pickup. The optical pickup is designed to move over the optical disc, allowing the light spot to cross tracks formed on the disc. Tracking error signals are detected from the reflected light beam, and track crossing pulses are generated based on these signals. The system determines if defects occur in the track crossing pulses and generates average or corrected average half periods accordingly. This method ensures that the optical pickup moves at a predetermined speed based on the generated reference half period.
Another notable patent is for a magnetic reproducing apparatus of a helical scan type. This apparatus features a rotary drum with a magnetic tape wound in a helical manner. It includes two sets of main and sub heads, each positioned closely together but with different azimuth angles. During special playback processes, the apparatus selects output signals from these heads to generate a reproduced signal, which is then processed to minimize timing differences in vertical sync signals.
Career Highlights
Kawase is currently employed at the Victor Company of Japan, Limited, where he continues to innovate in the field of technology. His work has significantly impacted the development of optical and magnetic devices, making them more efficient and reliable.
