Title: Innovations of Hidehiko Kikuchi
Introduction
Hidehiko Kikuchi is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of technology, particularly in signal conversion methods and power conversion devices. With a total of 3 patents to his name, Kikuchi's work reflects his expertise and innovative spirit.
Latest Patents
Kikuchi's latest patents include a telecine signal conversion method and an improved short-circuit protection for DC/AC power converters. The telecine signal conversion method is designed to convert an interlaced scan telecine signal generated by a 2-3 pull-down system. This method involves converting the first frame into an interlaced signal of the first and second fields, while the second frame is converted into an interlaced signal in the third, fourth, and fifth fields. The process includes detecting the pull-down phase of the interlaced scan telecine signal and generating progressively scanned telecine signals from the specified fields.
The improved short-circuit protection for DC/AC power converters consists of a power conversion device that includes semiconductor power elements and fuses connected in series. Feedback diodes are connected in antiparallel with the semiconductor power elements. This innovative layout prevents the fuses from melting during a D.C. short-circuit, as the current flows through a feedback diode or a bypass diode instead of the fuses.
