Latest Patents

One of Ezaki's latest patents is an analog amplification vacuum tube. This invention suppresses the influences of filament vibration on amplification characteristics. The design includes a filament, an anode, a grid, and a vibration-proof part. The filament is tensioned linearly and emits thermal electrons, while the anode is positioned parallel to the filament. The grid is strategically placed between the filament and the anode to enhance performance. The vibration-proof part features a thin film that is usable in a vacuum environment, which contacts part of the filament.

Another significant patent is for an electrode for an electron source, along with a method for producing the same and an electronic tube utilizing this technology. This invention aims to decrease the thickness of the electron emitting source and improve the current distribution percentage. The electronic tube consists of a substrate, an electron emitting source area, and a shield area surrounding the electron emitting area. The shield area is made from a material that does not produce an electron emitting source when the electron emitting source is created by a dry method. This innovation enhances the percentage of anode current in the total current, thereby improving overall efficiency.
