Abstract: An antistatic film installed in an airtight vessel containing an electron source of an electron-generating device such as a picture display unit has a structure comprising an image of conductor or semiconductor particles with particle diameters of 0.5 to 10 nm dispersed in a medium containing a nitride, an oxide or both; and thereby improves controllability for a resistivity value, stability and reproducibility, and the adequate temperature characteristics of resistance.

Abstract: A spacer, disposed between first and second substrates of an electron emission display, includes a main body, a resistive layer arranged on a side surface of the main body, a secondary electron emission preventing layer arranged on the resistive layer, and a diffusion preventing layer arranged between the resistive layer and the secondary electron emission layer. The diffusion preventing layer prevents interdiffusion between the resistive layer and the secondary electron emission preventing layer.

Abstract: A partition member for a gas discharge display panel having a front substrate with at least one main discharge electrode spaced from a back substrate having at least one auxiliary discharge electrode so as to delimit a gap therebetween. The partition member is adapted to extend substantially parallel to and between the front and back substrates for forming a main discharge space on a front substrate side and an auxiliary discharge space on a back substrate side, the partition member being a metal material member. A gas discharge display panel incorporates the partition member and a system is provided for driving the gas discharge display panel. Also, a manufacturing method is provided for the partition member and gas discharge display panel.

Abstract: A discharge display apparatus includes a plurality of first address electrodes (1) and a plurality of second address electrodes (2) both of which are disposed adjacent to each other so as to cross each other through a partition (6) and memory electrodes (3, 4) which have a plurality of apertures provided therethrough and are entirely covered with respective insulating layers (3a, 4a). The plurality of first and second address electrodes (1, 2) and the memory electrode (3, 4) are successively laminated and sealed into a tube body having discharge gas.

Abstract: A television pick-up tube includes a mesh assembly comprising a pair of superimposed support members having mutually adjacent support surfaces with a mesh electrode secured therebetween. Each of the support members has a centrally disposed aperture therethrough. The apertures are of a different size so that a portion of the support surface of one of the support members extends radially inwardly of the aperture in the other support member. The radially inwardly extending portion of the support surface has a fusion-resistant film of material thereon to prevent the mesh electrode from sticking thereto during the mesh assembly procedure. A method for forming the fusion-resistant film is also disclosed.

Abstract: A low volume, lightweight, high voltage electron gun having an overall size and weight of approximately 50% the size and weight of a conventional electron gun of the same output. This is accomplished by interposing between the cathode and the walls of the housing of the electron gun a thin piece of dielectric material of preselected breakdown strength. The dielectric material is in direct contact with both the cathode and the housing of the electron gun, with the voltage stress between the walls of the housing and the cathode being such that it does not exceed the breakdown strength of the dielectric material.

Abstract: A mesh electrode for a c.r.t. display device consists of a number of coplanar portions of mesh insulated from each other and secured to a support plate by means of a refractory compound incorporating particles larger than the pitch of the mesh. These particles space the mesh away from the support plate and allow the electrode to be easily fabricated.

Abstract: An improved transverse-discharge gas laser tube is provided by positioning thermionic cathodes diametrically opposite each other across the plasma location with anodes positioned at 90.degree. to the cathodes all contained within an electron repelling envelope. Laser configurations for both large and small circular cross-section plasmas are disclosed. A thermionic cathode plasma slab laser with a magnetic field that may be modulated to provide modulation of the laser beam is also disclosed.
