    Abstract: The conventional cathode for electronic tube has such a problem that the metal constituting the base material of the tube is thermally deformed and the fluctuation of the cut-off voltage becomes relatively large when an electronic tube is operated for a long time. In order to solve this problem, a cathode for electronic tube which can reduce the thermal deformation of the base material and does not allow the large fluctuation of the cut-off voltage is provided. The coefficient of thermal expansion of the metal constituting the base material (1) is made even by mixing the same metal (14) as that of a metallic layer (13) formed on the base material (1) in the metal constituting the base material (1), and the deformation of the base material (1) is suppressed by preventing the diffusion of the metal of the layer (13) to the base material (1).

    Abstract: PROBLEM TO BE SOLVED: To provide an X-ray cathode system and a method for manufacturing an X-ray cathode. SOLUTION: The disclosed embodiment includes an embodiment such as an X-ray tube cathode filament system. The X-ray tube cathode filament system includes a substrate and a coating (74) disposed on the substrate. In this cathode filament system, electron beams (18, 90) are emitted from the coating (74) but not from the substrate. The electron beams (18, 90) are generated by the use of the thermionic effect.

    Abstract: PURPOSE:To check a wasteful thermal loss from outside of a sleeve, while moreover missing no former function regarding a quick action thus realizing a fixed cathode structure by selectively blackening only the inside of a sleeve to form a blackened layer. CONSTITUTION:The present cathode structure consists of an emitter part 1, a sleeve 2 for supporting the emitter and of a heater (not illustrated) heating cathode. The heater is inside of the cylindrical sleeve 2 and when the heater is red-heated by the applied electric power, the sleeve indirectly-heated thereby heats a heated emitter part to emit electrons therefrom, whereby a blackened layer 2 is formed exclusively inside of the sleeve 2.
