Abstract: An apertured shadow mask in a color cathode ray tube (CRT) serves as a color selection electrode in permitting each of the three electron beams to be incident only upon its associated color-producing phosphor elements on the CRT's display screen. The apertures are arranged in vertical columns and horizontal rows in the shadow mask with aperture spacing defined by a vertical pitch (P.sub.v) i.e., the vertical spacing between adjacent apertures within the same vertical column where the apertures in one row are in different columns than the apertures in adjacent rows, and a horizontal pitch (P.sub.h), i.e., the horizontal spacing between adjacent apertures in the same horizontal row. To increase the color purity adjustment margin particularly in the corners of the display screen while still maintaining sufficient vertical spacing between adjacent phosphor dot color trios for a high degree of video image resolution, P.sub.

Abstract: A holder for maintaining an apertured shadow mask in fixed relation to the display screen of a color cathode ray tube (CRT) includes the combination of a mounting stud attached to an inner portion of the CRT's glass envelope and an apertured resilient metal holder attached to the shadow mask's peripheral frame and adapted to receive the mounting stud in a tight-fitting manner. A plurality of such mounting stud/metal holder combinations securely attach the top, bottom and lateral edges of the shadow mask frame to adjacent inner portions of the CRT's glass envelope adjacent its display screen. Heating of the shadow mask caused by the CRT's electron beams incident thereon gives rise to heating and thermal expansion of the shadow mask metal holders.

Abstract: An arrangement for mounting a shadow mask, or color selection electrode, in the glass envelope of a color cathode ray tube (CRT) includes four resilient metal holders, each spot welded to a respective upper, lower or lateral portion of the shadow mask's skirt. Each holder is formed from a unitary metal strip which is shaped so as to include an inner mounting portion spot welded to the mask's skirt and an outer apertured portion adapted to receive a stud attached to and extending inwardly from the CRT's glass envelope. The shadow mask undergoes thermal deformation, or doming, when heated by electron beams incident thereon and transfers heat to each of the metallic holders. Each of the metallic holders, in turn, undergoes thermal deformation, but because of the shape and orientation of the holders relative to the shadow mask, the four holders deflect the shadow mask in a direction generally perpendicular to and outward from the CRT's glass display screen, i.e., along the CRT's Z-axis.

Abstract: A knife holder includes two transparent plates, a plurality of partitioning blocks, a plurality of securing blocks, and a plurality of larger securing blocks. The partitioning blocks are spaced equi-distantly apart between the plates such that the plates define a receiving space. Upper ends of the plates are provided with a plurality of pairs of opposite indentations. The receiving space and the indentations are sized to receive knives. The knives are divided by the partitioning blocks so that they do not overlap. The partitioning blocks have front and rear ends forming bolt portions that pass through corresponding through holes in the plates for screwable engagement with the securing blocks so that the plates can be screwably secured on the partitioning blocks. The larger securing blocks are secured at two lower corners of each plate so that the knife holder can stand on a planar surface.

Abstract: A shadow mask, or color selection electrode, in a color cathode ray tube (CRT) is in the form of a thin metal foil and includes a large number of apertures through which electron beams are directed onto the phosphorescent coating on the CRT's display screen for forming a video image. The apertured shadow mask is also used with a light source during CRT manufacture to form a large number of spaced phosphor elements in the phosphorescent coating. Ideally, all of the beam passing apertures and phosphor elements are circular in cross-section, but the shadow mask is stretched and maintained under high tension when mounted in the CRT causing some of the apertures, particularly those adjacent its four corners, to also become stretched and assume an oval shape.
