摘要： 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).

摘要： The invention relates to the field of production of barium-scandate dispenser cathodes or other barium-scan-date materials. A target (66) containing a mixture of BaO, CaO, Al2O3 and SC2O3 tends to be more stable, the higher the scandia (scandium oxide) content is. However, an increased scandia content results in a reduced emission capability. A destabilizing effect of BaO and CaO reactions is counteracted by the more inert SC2O3 and also AI2O3 components, as not only an increased scandia content stabilizes the material but also an increased alumina (aluminum oxide) content improves the stability.

摘要： The present invention relates to a lighted switch used in input sections of various kinds of electronic devices, and a uniformly luminous EL sheet diaphragm and a lighted switch which is of a thin structure using the same are provided. The uniformly luminous EL sheet diaphragm is formed by molding a diaphragm portion 2 in a diffusion-type EL sheet which comprises a transparent electrode layer 4 formed on a transparent film 3, a light emitting layer 5, a dielectric layer 6, a rear electrode layer 7 and an insulating layer 8 in such manner that a light emitting surface is in a convex side, and the switch is provided by an electrode contact layer 9 newly formed on the insulating layer 8 in a concave side of the EL sheet diaphragm and an opposed electrode contact layer 11 formed on an insulating film base 10 opposite thereto, so that the thin structure can be achieved. Further, the transparent electrode layer 4 of the EL sheet diaphragm is formed by printing and drying a paste prepared by dispersing conductive powders that has a visible light transmittance in an insulating resin, and a high dielectric constant and flexible resin selected from vinylidene fluoride rubber and a blended resin of cyanated pullulan or cyanated cellulose and cyanated polyvinyl alcohol is employed as a binder resin for the light emitting layer 5 and dielectric layer 6, so that light emission failures due to wire breakage in the diaphragm portion 2 can be reduced, and a high quality EL sheet diaphragm and a switch using the same can be provided.
