Title: Mamoru Tsuzurabara: Innovator in Electron Tube Technology
Introduction
Mamoru Tsuzurabara is a notable inventor based in Mobara, Japan. He has made significant contributions to the field of electron tube technology, particularly in the design and production of magnetrons. With a total of 3 patents to his name, Tsuzurabara's work has had a lasting impact on the industry.
Latest Patents
One of Tsuzurabara's latest patents is for a cathode structure of an electron tube. This innovation focuses on a thermal electron emitting cathode of a magnetron, designed to prevent damage and breakage due to mechanical vibrations. The invention includes a spacer that is interposed between a center lead and a lower end shield, effectively mitigating vibration through the center lead. The antivibration effect is achieved by arranging the spacer with an aperture that allows the center lead and a side lead to extend, ensuring contact with the inner wall of a shielding member that forms part of the vacuum envelope of the magnetron.
Another significant patent is a method of producing magnetrons. This method involves incorporating a getter on at least one of the opposed surfaces of two end shields of a cathode. The getter is applied in a paste form containing getter metal powder, which is coated on the end shields and dried before the cathode filament is carburized. During the magnetron's exhaustion process, the dried paste is sintered to create a solid getter substance.
