Title: Innovations of Koji Kanbayashi

Introduction

Koji Kanbayashi is a notable inventor based in Chiba, Japan. He has made significant contributions to the field of display technology, particularly in cathode ray tube (CRT) systems. With a total of three patents to his name, Kanbayashi's work has had a lasting impact on visual display systems.

Latest Patents

One of his latest patents is for a CRT-matrix display with indexing and stair step vertical deflection. This invention provides a CRT-matrix type big screen display system that features self-emitting picture cells. It utilizes a sawtooth waveform for deflection and a step deflection waveform to eliminate scanning line inclination, thereby avoiding fluctuations in display brightness. This results in a satisfactory picture display. Additionally, the system incorporates index elements between primary color cells, which are scanned at the start of the operation to store positional information for video signal processing. Another significant patent is for a matrix array of cathode ray tubes display device. This invention consists of multiple cathode ray tubes arranged in an X, Y matrix, with each tube containing pixels that are designed for optimal viewing angles. The front panel of the cathode ray tube is engineered with a thinner portion to minimize spacing between adjacent tubes.
