Abstract: An indirect cathode sleeve and manufacturing method thereof capable of substantially reducing electric power consumption of a heater disposed inside the cathode sleeve and simultaneously reducing a picture-producing time by oxidizing an inside surface of the cathode sleeve and reducing an outside surface thereof. The cathode sleeve includes a heater disposed inside the cathode sleeve; a base metal formed at the top of the cathode sleeve; an electron-emitting material layer formed at the outside surface of the base metal; and an indirect cathode sleeve including a black inside surface and a white outside surface. The method for manufacturing the indirect cathode sleeve includes the steps of forming a structure of a cathode sleeve consisting of a bimetal which consist of a Nickel-Chrome alloy at an inside surface of the cathode sleeve and a Nickel alloy at an outside surface of the cathode sleeve; oxidizing the inside surface of the cathode sleeve through a high temperature wet hydrogen environment; selectively etching the outside surface of the cathode sleeve and, as a result, forming a base metal at the top of the cathode sleeve; and forming an electron-emitting material layer at the outside surface of the base metal.

Abstract: A cathode having a short heating time and a long lifetime for an electric discharge tube is provided. The cathode comprises a metal (particularly nickel) support base coated with a layer of potentially electron-emissive material, which support base has a thickness ranging between 20 and 150 .mu.m, while the metal crystallites have a size which does not permit of any further crystallite growth or recrystallization. Particularly, the crystallites of the support base have a size which corresponds to the thickness of the support base. The cathode is obtained by a method in which the recrystallization thermal treatment is effective to prevent additions in the metal of the support base from forming oxides to a depth which is further than 1 micrometer from the surface.

Abstract: A thermionic cathode of tungsten or molybdenum is made with an activating content of lanthanum oxide and is supplied with a carbonaceous reducing agent either by incorporation in the bulk material of the cathode body or by carburizing, so that the reducing agent comprises at least in part a carbide of the carrier metal. Lower operating temperatures and higher emissivity are obtained compared to thoriated tungsten filaments and longer useful life compared to other cathodes activated by other rare earth oxides. The temperature-emissivity characteristics are such that good results are obtainable even within the temperature range in which molybdenum is usable as a carrier material.

The closure is diversely shaped to have a mesa-like terminal portion, with the planar end surface thereof formed to provide a flat substrate area to accommodate the deposition of electron emissive material thereon. A strengthening transition portion extends from the periphery of the mesa-like portion to form an annular shoulder therearound. A peripheral skirt portion, extending downward from the shoulder, is of a length and internal diameter to facilitate encompassment and affixation to the terminal portion of the sleeve.
