    Abstract: A cathode-ray tube eg. a shadow mask colour tube, includes a rectangular faceplate which has an exterior surface having curvature along both the minor (Y-Y) and major (X-X) axes wherein at least in the center portion of the faceplate, the curvature along the minor axes is greater than the curvature along the major axis (as shown in Figure 6). In a preferred arrangement the curvature along the minor axis is at least 4/3 greater than the curvature along the major axis. The arrangement provides a substantially rectangular contour near the periphery of the faceplate lying in a plane P thus creating an illusion that a picture produced on the faceplate is flat. The faceplate may be associated with a shadow mask which similarly has greater curvature along its minor axis than along its major axis. Variations in the thickness of the faceplate are also discussed.

    Abstract: The present invention provides an improvement in an apertured mask type color picture tube having a faceplate, a cathodoluminescent screen on the faceplate, a corrugated apertured mask adjacent the screen and an electron gun means for producing and directing a plurality of electron beams through the mask to impinge upon the screen. The mask is constructed by first forming the apertures therein and thereafter forming the mask in a corrugated shape. Aperture width in the apertured but unformed mask is adjusted to compensate for stretching and compression of the mask occurring during formation of the mask into a corrugated shape. Therefore, the corrugated mask is substantially free of aperture width variation from that desired caused by forming the mask in a corrugated shape.

    Abstract: The mount includes a plurality of springs interconnecting a yoke to a cathode-ray tube. The springs may be formed on a yoke housing and connected to a platform attached to the tube or connected directly to the tube. Alternately, the springs may be formed in the platform connected to the yoke housing.

    Abstract: Improvement is provided in the appearance of a color picture type cathode-ray tube including rectangular faceplate with an exterior surface having curvature along both the minor (Y-Y) and major (X-X) axes. At least in the center portion of the faceplate, the curvature along the minor axis is at least 10 percent greater than the curvature along the major axis. Points on the exterior surface near the ends of the major axis, at the edges of the screen, lie in a first plane (P1) perpendicular to the central axis (Z-Z) of the tube; points on the exterior surface near the ends of the minor axis, at the edges of the screen, lie in a second plane (P2) which is spaced from and parallel to the first plane; and points on the exterior surface near the ends of the diagonals of the rectangular faceplate, at the edges of the screen, lie in a third plane (P3) which is spaced from and parallel to the first plane. The three planes are spaced from the center portion of the faceplate in the order of second plane, first plane and third plane. Further relative dimensions are detailed.

    Abstract: A method of making a grid for a cathode-ray tube includes the process of etching an electrically conductive base member of a first material from two sides through related openings in electrically conductive layers of a second material which overlays the two sides of the base material. Etching continues until an aperture of sufficient size is formed that the overlying layers overhang the aperture in the base member.

    Abstract: Essentially, the device comprises a rigid transparent substrate, such as glass, and a nonsolarizing polymer layer, such as silicone resin, on the substrate. An effective surface is formed on the surface of the polymer layer opposite the substrate.
