    Abstract: A cathode ray tube having, a panel portion provided with a phosphor screen on its inner surface, a neck portion provided with an electron gun in its inner space, and a funnel portion combined with the panel portion and the neck portion to provide an envelope, in which the electron beam emitted from the electron gun scans the phosphor screen and produces images, and the images are observed from the beam scanning side of the phosphor screen. In the cathode ray tube a thin metal oxide layer is formed on the beam scanning side of the phosphor screen.

    Abstract: PCT No. PCT/JP84/00131 Sec. 371 Date Nov. 21, 1984 Sec. 102(e) Date Nov. 21, 1984 PCT Filed Mar. 23, 1984 PCT Pub. No. WO84/03796 PCT Pub. Date Sep. 27, 1984.The present invention relates to a cathode ray tube suitable for use with a flat type cathode ray tube in which a material from which a secondary electron is emitted by the impingement of an electron beam is exposed on a surface of an area of a first panel portion (2) having on its inner surface formed a phosphor screen on which the electron beam from an electron gun impinges and an insulative material which forms a second panel portion (3) is exposed on an inner surface of the second panel portion (3) opposing the first panel portion (2) wherein the secondary electron is accumulated to present a predetermined high potential state so that an electric field is prevented from being disturbed in a path of the electron beam.

    Abstract: 1,130,720. Colour television tubes. SONY CORP. 13 April, 1966 [16 April, 1965], No. 16158/66. Heading H1D. In a method of making a multi-colour screen for a colour television display tube of the type utilizing a colour-switching grid of parallel wires or a similar post deflection focusing device adjacent the screen involving a photographic process in which areas of the screen are exposed to a point source of light through an optical mask having a pattern determined by the electron trajectories, the correct positioning of the mask is obtained by the preliminary use of a positioning plate provided with parallel opaque areas corresponding to the areas between the grid wires, this plate being adjusted until a spurious moire pattern resulting from light interference with the grid wires is removed and the plate then being replaced by the optical mask either in the same or an equivalent position. The optical mask may be prepared by first producing a negative by an electron beam printing method or by a photographic or tracing method depending on the scanning pattern of an electron beam and then producing the mask from the negative by a photographic process. After the first, red, phosphor areas are laid down on the faceplate, the remaining green and blue areas are successively laid down by a technique involving protecting certain areas by opaque material and exposing other areas to light from outside the faceplate without the use of a mask. The tube may be of the singlegun or plural-gun type.
