Abstract: A directly heated cathode structure includes a porous pellet impregnated with a cathode material, a first metal member fixed to a surface of the porous pellet, a second metal member welded to the first metal member, and a filament interposed between the first and second metal members. A method for manufacturing a directly heated cathode structure includes manufacturing a porous pellet having a multiplicity of cavities, welding a first metal member to a surface of the porous pellet with a brazing layer, impregnating the cavities of the pellet with an electron radiating material, and welding a second metal member to the first metal member with a filament disposed between the first and second metal members. The useful life of the cathode structure is prolonged since thermions are not emitted through the surface of the pellet covered by the metal member.

Abstract: A display apparatus for displaying pictures virtually instantaneously adopts a direct-heating type cathode of an impregnated structure, and includes a cathode ray tube having a dispenser cathode wherein a cathode material is filled in pores of a porous body and a porous heater is directly connected to the cathode material. A voltage generator of the apparatus produces a first voltage for driving the heater. A video signal supply portion supplies a video signal to the cathode, while a deflector deflects horizontally and vertically an electron beam generated from the cathode to produce a raster by scanning the fluorescent surface of the cathode ray tube. A flyback transformer generates a second voltage to be supplied to the anode and one or more grids of the cathode ray tube using a horizontal deflection output signal supplied from the deflector. With the described arrangement, an electron-emitting velocity of an electron gun reaches its maximum value within about one second after power is applied. Thus, the display apparatus can be adapted to an HDTV requiring high current density electron-emitting characteristics.

Abstract: An improved scandate cathode is made from a hollow cylinder of a metal thatill not react with Sc.sub.2 (WO.sub.4).sub.3. The first step in making such a cathode is to insert a metal plug at the bottom of the cylinder to a height that will allow the remaining volume of the cylinder to be filled with the reactants WO.sub.3 and Sc.sub.2 O.sub.3. Next, the reactants are heated in a vacuum to about 1100.degree. C. to form the reaction product Sc.sub.2 (WO.sub.4).sub.3. The plug is then removed from the cylinder, the cylinder is inverted, and BaH.sub.2 is added to the volume of the cylinder that had been occupied by the plug. Finally, the cylinder is heated to decompose the BaH.sub.2.

Abstract: A cathode and a process of manufacturing the same are disclosed, the cathode comprising; a molybdenum cup having a convex portion, free barium atoms produced through reactions with an impregnation compound, a porous metal layer sealingly welded to the top of the cup, and a heating member having an uppermost head portion inserted into the lower space of the convex portion of the cup.

Abstract: Porous agglomerates are made from pure tungsten by sintering fine particles together and mechanically breaking down the mass to form some agglomerates considerably larger than the particles. These agglomerates are mixed with fine iridium powder and sintered to form a porous mass. The mass is machined to the cathode shapes and impregnated with an alkaline earth aluminate. The large agglomerates alloy with the iridium only on their outer surface. Their pure tungsten interior provides the surfaces to reduce the alkaline earth oxide to the metal which activates the cathode.
