Introduction

Kunihiko Fujii is a notable inventor based in Osaka, Japan. He has made significant contributions to the fields of video signal processing and injection apparatus technology. With a total of 3 patents, his work has had a lasting impact on various industries.

Latest Patents

Fujii's latest patents include a vertical synchronizing signal generation apparatus and a video signal processing apparatus. The vertical sync signal generator features a vertical sync signal separation circuit that separates a vertical sync signal from an input luminance signal. It outputs the separated signal as a first vertical sync signal. Additionally, it includes an automatic frequency control circuit that generates a second vertical sync signal with a repeat frequency corresponding to the average repeat frequency of the first vertical sync signal. A vertical sync signal phase detection circuit detects whether the first vertical sync signal has two different periods repeated alternately, outputting the detection result as a decision signal. A selector receives both the first and second vertical sync signals, selecting the appropriate signal based on the decision signal.

Fujii's injection apparatus includes a first switching valve that connects to various injectors, allowing for efficient delivery of sample liquids into selected columns. This sequential switching of valves enables the sample liquids packed in the injectors to be effectively dispensed or analyzed by a chromatograph.
