Title: Eiji Munemoto: Innovator in Display Technology

Introduction

Eiji Munemoto is a notable inventor based in Kanagawa, Japan. He has made significant contributions to the field of display technology, particularly in the development of cathode-ray tubes and discharge display devices. With a total of 2 patents, Munemoto's work has had a lasting impact on the industry.

Latest Patents

One of Munemoto's latest patents is a color cathode-ray tube with an electron beam selection mask support. This invention features an electron beam selection mask with an aperture grille type beam selection electrode made from a thin metal plate. The mask is supported by stud pins engaging with support springs, ensuring stable positioning opposite a color luminescent screen. The design includes projections and recesses for engagement, coated with solid lubricant films to maintain proper positioning despite external impacts. Additionally, the elasticity constant of the frame can be adjusted with reinforcing plates, preventing vibration of the beam selection mask. Rotary mechanisms are also incorporated to shift the frame toward the panel surface, preventing mislanding of the electron beam due to temperature changes.

Another significant patent by Munemoto is a method of producing a discharge display device. This method allows for the formation of a satisfactory LaB6 cathode without the use of a glass binder. The process involves applying a conductive paste, temporarily drying it, and then forming a LaB6 layer without a glass binder. Both layers are burned simultaneously, and the LaB6 layer is activated after an exhausting step by gas discharge with large current, resulting in the formation of a LaB6 cathode.
