    Abstract: A method for manufacturing a mask for a color CRT. The mask comprises a plurality of mask members (1, 3) having a number of apertures for passing electron beems (33), and being spaced apart. The mask is produced by the steps of bringing the mask members (1, 3) into tight contact with an insulator (13) interposed between their peripheries; fixing them by an adhesive; press forming the entire composite; melting the adhesive; and shifting apart and fixing the mask members (1, 3) at a predetermined distance.

    Abstract: A color cathode-ray tube (20) in which, opposing to a color fluorescent screen (5) so configured that stripes (9) of luminescent materials each capable of emitting light of a color are arranged in parallel to each other in a predetermined order, an aperture grille (10) in which a number of slits (4) extending in the longitudinal direction of the stripes (9) are made in parallel to each other is provided, the aperture grille (10) is so configured as to stretch a thin plate (1) having the slits (4) on a frame (3) with a required tension in the longitudinal direction of the slits (4). The thin plate (1) is a thin high purity iron plate having a thickness of 0.05 mm or less. Since the controllability of the widths of the slits in manufacturing is improved by virtue of the specified thickness of the thin plate, the precision and productivity of the aperture grille can be improved and the weight thereof can be reduced. Further, a fine structure screen for color cathode-ray tubes can be manufactured.

    Abstract: Method of fabricating an improved multiple grid electrode having a plurality of discs by simultaneously forming a dimpled segment in a sandwich structure consisting of metallic discs (42, 43, 44) separated by spacer material (46, 47). The dimpled sandwich structure is then machined, forming a series of vanes on the dimpled portion by an appropriate method, such as electrical discharge. After machining, the spacer material (46, 47) is etched away, leaving only the vaned discs, (42, 43, 44) forming grid electrodes.

    Abstract: Spherically convex microgrids may be prepared from a flat microgrid structure by using a process depending on the differential thermal expansion between the material of the flat structure and a layer of other material applied thereto. A flat process blank 2 is etched with grid apertures in a microgrid area to which a curvature is to be added during fabrication. The blank is then subject to the deposition of a thin layer 4 of aluminium nitride (or other differential thermal expansion material having a positive thermal expansion mismatch with the material of the microgrid substrate) over at least the microgrid area (Step A). The differential thermal expansion layer is coextensively with the grid area, so as to confine the warping substantially to the grid area where curvature is desired. Curvature (Step B) is accomplished by a controlled heat warping step in an inert atmosphere (for a silicon microgrid structure of 250 micrometers thickness, heating at 1200C to soften the silicon). Permanent deformation, occuring as a result of the differential thermal expansion, is controlled by selection of temperature and time of heat treatment to achieve the desired curvature. The aluminium nitride layer (Step C) is removed prior to cooling.
