Title: Tsuyoshi Hiraki: Innovator in Signal Processing and Information Recording

Introduction

Tsuyoshi Hiraki is a notable inventor based in Osaka, Japan. He has made significant contributions to the fields of signal processing and information recording, holding a total of 2 patents. His work has been instrumental in advancing technology in these areas.

Latest Patents

Hiraki's latest patents include an interchannel skew adjustment circuit and an information recording system and method. The interchannel skew adjustment circuit is designed to adjust signal skew between a first channel and a second channel. This circuit features a phase adjustment circuit that receives a signal from the first channel, delays it by a discretely variable amount, and outputs a delayed signal. Additionally, it includes a channel coupling circuit that detects the phase difference between the two signals and a controller that adjusts the delay based on the detected result. This innovation effectively reduces circuit area and power consumption by adjusting interchannel signal skew at either the sender or receiver.

The information recording system is designed for recording information on an optical disc using a reference clock signal generated from a push-pull signal that includes a wobble frequency component. This system comprises an amplitude obtaining unit, a threshold calculation unit, and a noise reduction unit. The noise reduction unit generates a corrected push-pull signal, which helps in producing a reference clock signal based on the corrected data.
