Title: Akihito Sudo: Innovator in Cathode Ray Tube Technology
Introduction
Akihito Sudo is a notable inventor based in Mobara, Japan, recognized for his contributions to the field of cathode ray tube technology. With a total of five patents to his name, Sudo has made significant advancements that enhance the quality and efficiency of cathode ray tubes.
Latest Patents
Sudo's latest patents include innovative designs for cathode ray tubes. One of his patents focuses on a method for creating a punched electrode profile with a predetermined angular range. This method involves forming profile lines of plate-like grid electrodes through a first punching step, followed by the creation of separation lines in a subsequent step. The design ensures that the angle of the crossing portion between the profile line and the separation line is maintained between 70 and 110 degrees. This configuration reduces burrs on the plate-like grid electrode, which is crucial for the electron gun of a color cathode ray tube, ultimately enhancing the quality and reducing the manufacturing time of the cathode ray tube.
Another significant patent by Sudo describes a cathode ray tube featuring an improved electrode assembly. This design includes a phosphor screen and an electron gun, which consists of an electron beam generating section and a focusing section. The innovative assembly allows for precise focusing of the electron beam onto the phosphor screen, utilizing a compound electrode made from a thicker material than the other components. This design improves the overall performance and reliability of the cathode ray tube.
