Title: Chojiro Terao: Innovator in Television Technology
Introduction
Chojiro Terao is a notable inventor based in Amagasaki, Japan. He has made significant contributions to the field of television technology, particularly in the synchronization of horizontal deflection signals. With a total of 2 patents to his name, Terao's work has had a lasting impact on the industry.
Latest Patents
Terao's latest patents focus on an apparatus and method for synchronizing a horizontal deflection signal. This innovation is part of an automatic frequency control circuit designed to synchronize the horizontal deflection current of a television receiver with a horizontal sync signal. The system produces a bi-level signal that assumes either of two levels when the flyback pulse is at or below a threshold value. Additionally, it generates a wider sync signal in synchronism with the horizontal sync signal, which has a pulse width wider than the horizontal sync signal and is equal to an odd multiple of the operating clock period. A phase comparator is utilized to detect the difference in the number of clock periods between specific periods of the sync signal and the bi-level signal. This detected difference is then used to control a voltage-controlled oscillator (VCO). In an alternative configuration, a digital signal indicative of the magnitude of the flyback pulse during its rising or falling slope at the edge of the horizontal sync signal is produced for VCO control.
Career Highlights
Terao is currently employed at Mitsubishi Electric Corporation, where he continues to innovate in the field of electronics. His work has been instrumental in advancing television technology, particularly in enhancing the synchronization processes that are crucial for optimal performance.
