Title: Haruo Nakatsuji: Inventor in Display and Digital Recording Technologies.

Introduction

Haruo Nakatsuji is an inventor associated with Ikoma, Japan. His recorded patent work covers cathode-ray-tube display screening and digital audio recording. He is associated with Sharp Kabushiki Kaisha Corporation and has 2 patents.

Latest Patents

Nakatsuji’s listed patents address two distinct technical challenges.

“Screening Structure for a Cathode Ray Tube Display” describes a structure that screens components of a cathode-ray-tube display. Conductive screening members envelop the pin socket, input pin, video amplifier section, and cathode section. The members are connected so they remain at the same high-frequency potential, and a low-impedance cable connects them to the display’s standard-potential part.

“Method for Recording Digital Information” concerns recording digital information immediately after a silence interval. The method records a signal sound at a predetermined level at the beginning of the digital information. It may also place a silence interval between that signal sound and the digital information.

Career Highlights

Nakatsuji’s patent portfolio reflects work on both electronic display design and recording methods. The display invention focuses on conductive screening and high-frequency potential, while the recording invention uses a signal sound to mark the start of digital information.

Collaborations

Toru Yasui and Toshiyuki Maegawa are identified as Nakatsuji’s coworkers. The available information does not specify their roles in the listed patents.

Conclusion

Haruo Nakatsuji’s recorded inventions span cathode-ray-tube display screening and digital information recording, reflecting contributions to two areas of electronics technology.
