Abstract: At least an effective region of the face of a panel of a cathode ray tube is held within a vacuum chamber. After the vacuum chamber is hermetically sealed from the outside of the vacuum chamber, a thin film is formed on the face of the panel by using a film-forming means.

Abstract: A cathode assembly (27) includes a thermally conductive insulating substrate (21) having a pair of opposing surfaces. A cathode base member (24) is formed on one surface of the insulating substrate, and a heating member (25) for heating the cathode base member is formed on the other surface of the insulating substrate. A heater electrode terminal (26) is fixed to the electrode of the heating member through a metal layer (26a). A first grid (30) is fixed to the insulating substrate to oppose the cathode base member through a predetermined space.

The coupling assembly includes a rotatable shaft mechanism having at least one shaft rotatable about an axis thereof in response to operation of the control lever assembly, an arm swingable about the shaft in response to rotation of the shaft for tilting the mirror holder, and a clutch assembly for selectively disconnecting the control lever assembly from the mirror holder, the clutch assembly including a cam on the shaft and a flat spring assembly between the arm and the shaft for resiliently engaging the cam.

Abstract: An automotive rearview mirror assembly includes a mirror housing adapted to be mounted on a fixed member of an automobile outside of the passenger's compartment, a mirror swingably disposed in the mirror housing, a control mechanism including a control lever adapted to project from the housing into the passenger's compartment, and a rotatable shaft mechanism pivotally coupled to a rear surface of the mirror at a plurality of positions thereon, the rotatable shaft mechanism being rotatable in response to control movements of the control lever, for vertically and laterally adjusting the angle of the mirror with respect to the mirror housing. The mirror housing is angularly movable about the axis of the rotatable shaft mechanism in unison with the mirror within the mirror housing.

Abstract: An indirectly heated type cathode assembly comprises a cathode sleeve having a heater within itself and having an emitter-impregnated type cathode disc fitted at one end, a plurality of straps connected at one end to a lower end portion of the cathode sleeve, and a cylinder holder whose upper end is connected to the other end of each strap, the holder being located outside the cathode sleeve such that it is spaced a predetermined distance apart from the cathode sleeve. A heat reflecting cylinder is located between the cathode sleeve and the holder of the indirectly heated type cathode assembly such that it is coaxial with the cathode sleeve and holder. The heat reflecting cylinder is supported by the holder and each strap extends such that it is not in contact with the heat reflecting cylinder. The strap is made of a Ta-W alloy or a Ta-W-Hf alloy.

Abstract: According to the present invention, an impregnated cathode is provided wherein an alloy layer of iridium and tungsten is formed on a surface of a porous pellet impregnated with an oxide of an alkali earth metal, wherein a crystal structure of the alloy has an .epsilon.II phase comprising an hcp structure whose lattice constants a and c satisfy 2.76.ltoreq.a.ltoreq.2.78 and 4.44.ltoreq.c.ltoreq.4.46, respectively. The impregnated cathode of the present invention maintains stable electron emission characteristics from an early stage of operation.

Abstract: An output phosphor film used in an output screen of an image intensifier is made of ZnS or (Zn, Cd)S host material and at least one activator element selected from the group consisting of Cu, Ag, Au, Al, and Cl. The phosphor film is formed on a face plate by means of chemical vapor-deposition, or physical vapor deposition in an inert-gas atmosphere having a pressure of 1 Pa or more, and is heat-treated. The formed phosphor film has hexagonal (Wurtzite-type) crystal and/or cubic (sphalerite-type) crystal structure. These crystals are orientated such that the (002) planes of the hexagonal crystals and/or the (111) planes of the cubic crystals are substantially parallel to the face plate.

Abstract: An indirectly heated cathode structure for electron tubes comprises a cathode supporting sleeve, an electron emission section fitted on a part of the supporting sleeve, and a heater arranged inside the supporting sleeve, the supporting sleeve being an alloy containing niobium as a main component, more particularly more than 85 weight % of niobium. As an additive, at least one metal selected from titanium, zirconium, hafnium, vanadium, tantalum, molybdenum and tungsten is used.

Abstract: A support and drive unit for a mirror device having a housing and a mirrored mirror holder, includes a casing adapted to be disposed in the housing, a support structure adapted to pivotally support the mirrored mirror holder, and means for adjusting the mirror holder. The adjusting means comprises first and second actuating rods axially movably mounted on the casing, and a pair of motors disposed in the casing for moving the actuating rods, respectively, through coupling means. The actuating rods have front ends adapted to be pivotally coupled to the mirror holder, and are spaced substantially right-angularly from each other around the center of the support structure.

Abstract: A getter device is disclosed in which at least on the exposed surface of a getter material filled in a metal getter container and containing a barium-aluminum alloy powder and a nickel powder is formed a gas-impermeable film of a boron compound or a mixture of a boron compound with silicon oxide.
