    摘要: The present invention is an improvement in a method of screening a line screen slit mask color picture tube that includes coating a faceplate panel of the tube with a photosensitive material, inserting a slit shadow mask into the panel and exposing the photosensitive material by passing light from a line light source through a misregister correction lens and through the slits of the mask. The improvement comprises positioning a skew correction lens between the line light source and the misregister correction lens during exposure of the photosensitive material. The skew correction lens has a surface with a general overall cylindrical shape with deviations from the cylindrical shape being in the four corners of the skew correction lens.

    摘要: The present invention provides an improvement in a color picture tube having a tensioned mask and support frame assembly. Each of the mask and the support frame is rectangular and has two long sides that parallel a central major axis thereof and two short sides that parallel a central minor axis thereof. The mask has a substantially cylindrical contour, being curved along the major axis and straight along the minor axis. The improvement comprises the frame including two first members that parallel the major axis and two second members, attached to the ends of the first members, that parallel the minor axis. Each of the first members includes a rigid section and a compliant section cantilevered from the rigid section. The mask is attached to the distal ends of the cantilevered compliant sections.

    摘要: An improved color picture tube includes an evacuated envelope having a rectangular faceplate panel. The panel includes a viewing screen on an inner surface thereof and a shadow mask assembly mounted therein by support means located at the four corners of the panel. The shadow mask assembly includes an apertured shadow mask and a peripheral frame to which the mask is attached. The frame is formed by four sections that are welded together at their ends. Two of the sections are longer than the other two sections and are constructed of a material having a different coefficient of thermal expansion than that of the other two sections. The frame reduces electron beam misregister with elements of the screen.

    摘要: The improved color picture tube includes an evacuated glass envelope having a rectangular faceplate panel with two long sides and two short sides. The panel includes a major axis paralleling the two long sides, a minor axis paralleling the two short sides and two diagonals that extend between opposing corners of the panel. The panel includes a shadow mask assembly mounted therein by support means that are located at the corners of the panel. The support means at each of the spaced positions includes a stud attached to the glass envelope and a spring having an aperture therein engaging the stud. The improvement comprises the studs being located slightly off of the diagonals of the panel between the diagonals and the major axis.

    摘要: The improved color picture tube includes an evacuated glass envelope having a rectangular faceplate panel. The panel includes a shadow mask assembly mounted therein by support means that are located at peripherally spaced positions within the panel. The support means provide compensation for thermal expansion of the shadow mask assembly. The compensation is a movement of the shadow mask assembly toward a screen of the tube as the shadow mask assembly expands. The support means at each of the spaced positions includes a stud attached to the glass envelope, a spring having an aperture therein engaging the stud, and a plate welded between the spring and the shadow mask assembly. The improvement comprises the combination of the spring being angled with respect to the shadow mask assembly to provide approximately half of the required compensation, and the plate being constructed of bimetallic materials and being of appropriate thickness and length to provide the approximately remaining half of the required compensation.

    摘要: In the novel method, the widths of the parallel luminescent stripes of a luminescent viewing screen are scanned by a beam of ultraviolet light whereby the stripes are excited to emit light along the path of scan. The emissions of the light in an identifying spectral band are sensed with respect to the position of the light beam on the screen and converted to a train of electrical signals. Then, the average width of the stripes identified by the spectral band is calculated from the distance over which the intensities of the signals are continuously above an assigned value.
