    Abstract: A structure wherein a cathode, which is made of a material, such as lanthanum hexa-borides, prone to react with metals at high temperatures and having a high electron emissivity, is held by a supporter which is made of an electrically insulating material. Concentric metal cylinders are arranged at the outer circumference of the supporter to surround a part of the cathode and a heating coil is arranged in the interstice between the metal cylinders. An electron-emissive metal oxide layer is formed on the inside surface of the inner metal cylinder. Thermions created from the oxide layer strike the cathode, and the cathode is heated by the heat of the electron bombardment.

    Abstract: An improved indirectly heated cathode structure is provided for use in an electron gun of a cathode ray tube. A cathode sleeve having top and bottom open ends has a terminal ledge formed at the open top thereof. A planar closure member, having a perimetric shape similar to that of the sleeve, is seated on and affixed to the ledge thereby providing a flat substrate upon which electron emissive material is subsequently disposed.

    Abstract: In a base plate assembly including an insulative substrate for a luminescence display tube and grid supports formed on the substrate along side edges thereof, a plurality of protrusions are extended sideways from the body of the substrate beyond the grid supports. When each of the grid supports has a protrusion left after cutting of the supports from two frames, the protrusions of the substrate are extended beyond the protrusions of the grid supports.

    Abstract: An electron gun filament support structure in which the electron-emitting filaments are held in place by a plurality of opposing leaf springs. In a preferred embodiment, the springs are mounted on a filament tray, with the leaf of each spring extending substantially perpendicularly to the tray. Each leaf has one or more slots in its upper edge. The arms of each slot curve substantially outwardly from the opposing leaf springs, whereby a filament having enlarged end portions inserted in the slots of opposing leaf springs is held firmly in place under tension. Damaged or destroyed filaments may readily be removed and new filaments inserted by pressing opposed leafs toward each other, removing one filament, inserting another, and releasing the springs.

    Abstract: An electron gun for a cathode-ray tube has a cathode centrally mounted in a ceramic ring. The ring has a metal holder comprising a flat plate with means extending about the periphery of the ring and forming a clamp against the other side. The cathode assembly is held in the electron gun assembly by embedding the edges of a flat plate extending from the ring into a pair of glass beads. The cathode is critically spaced from a grid comprising a flat apertured plate by having edges of the plate embedded in the same glass beads.

    CPC classification number: H01J29/04

    Abstract: A cathode assembly for use in an electron discharge device wherein one end of the cathode sleeve is closed by a cap having electron emissive material exteriorly disposed thereon. The end portion of the sleeve underlying the sidewall of the cap is formed as a shield to provide a space between the sleeve and the cap except for limited seating and bonding contact therebetween at substantially the rim portion of the cap. Since the cathode assembly so formed provides limited heat conduction and radiation between the sleeve and the cap, the emissive cap area receives the major portion of its operational heat by direct radiation from the heater oriented within the cathode sleeve.
