Title: Shuichi Ishii: Innovator in Clock Signal Technology

Introduction

Shuichi Ishii is a notable inventor based in Sayama, Japan. He has made significant contributions to the field of clock signal technology, holding a total of 3 patents. His work focuses on improving the efficiency and accuracy of clock signal supply methods and integrated logic circuits.

Latest Patents

One of his latest patents is a "Clock signal supply method and system." This invention provides a method for generating a reference signal, a synchronizing signal, and a clock signal at a clock signal generating source end. Both the reference and synchronizing signals have a longer period than the clock signal. The clock signal at the destination end is frequency divided in synchronism with the synchronizing signal, allowing for a sample to be compared with the reference signal. The resultant frequency-divided signal is then compared with the reference signal in phase, enabling delay control for the clock signal based on the comparison results. Another significant patent is for an "Integrated logic circuit with clock skew adjusters." In this invention, multiple clock skew adjusters generate clocks with coincident phases based on frequency and phase information from a clock source. The arrangement of the clock source and adjusters ensures that their individual signal delays are substantially equalized.
