A color cathode-ray tube has an evacuated envelope with an electron gun therein for generating an electron beam. The envelope further includes a faceplate panel having a luminescent screen with phosphor elements on an interior surface thereof. A focus mask, having a plurality of spaced-apart first conductive strands, is located adjacent to an effective picture area of the screen. The spacing between the first conductive strands defines a plurality of apertures substantially parallel to the phosphor elements on the screen. Each of the first conductive strands has a substantially continuous insulating material layer formed on a screen-facing side thereof. A plurality of second conductive wires are oriented substantially perpendicular to the plurality of first conductive strands and are bonded thereto by the insulating material layer. The insulating material layer is partially or slightly conductive to an extent sufficient to prevent an accumulation of a significant electrical charge.

A tension mask frame assembly for a color cathode-ray-tube including a frame having four respective sides, two of the sides paralleling each other and having insert receiving brackets for supporting strand termination inserts therein and vertical mask strands welded to said termination inserts. The strands have a plurality of cross-wires extending perpendicular to the strands and attached thereto by a conductive bonding material. The wires and termination inserts are composed of materials having a first coefficient of thermal expansion. The frame and receiving brackets are composed of materials having a second coefficient of thermal expansion. The termination inserts thermally expand and contract independently of the frame and receiving brackets, whereby movement of the strands in the horizontal dimension is controlled by thermal expansion and contraction of the termination inserts and cross-wires.

Tension mask frame assembly for a CRT

A color picture tube has a tensioned mask supported by a support frame mounted within said tube. The mask has a significantly lower coeffiecient of thermal expansion than the frame. Intermediary members are located between the mask and the frame. The intermediary members are of a material similar to that of the mask. Each of the members is attached to the frame at a single location and the mask is attached to edges of the intermediary members. Further included are guides for holding the intermediary members to the frame while permitting expansion of the frame relative to the intermediary members.

In an integrated thermal processing method the bulb is completely processed in a dedicated oven. The inside and outside of the bulb are simultaneously heated. The inside and outside are also simultaneously cooled. During the evacuation a temperature gradient is maintained across the face of the panel to reduce tensile stresses which develop in the bulb skirt area during evacuation.

In a method of manufacturing, the steps of: providing a workpiece comprising a main body and a machine-readable marking on a portion of the body, depositing on the marking and the surrounding surface an overcoating of a liquid polymeric composition that is curable by exposure to ultraviolet radiation, and then irradiating the liquid overcoating with ultraviolet radiation so that the overcoating cures to a solid nontacky, light-transmitting protective coating. The workpiece, with the cured protective coating thereon, may be subjected to processing steps wherein extraneous matter may adhere to the coating, and then be cleaned leaving the cured coating intact.

A workpiece having a machine-readable coded marking abraded into the surface thereof. The marking comprises a plurality of related marks, such as bar-code marking, which have substantially different light reflectances than the surrounding surface. The markings may be made by moving a means for abrading a defined surface area along a particular path with respect to the surface to be marked. The abrading means is selectively activated or deactivated according to a prearranged program to selectively abrade the surface.

A video disc record suitable for use with a video disc player apparatus is provided with a label for identifying the program material stored on the surface of the record. The label is formed in a machine readable format which comprises grooves in the surface of the record. In one format whorls of a spiral groove of a first pitch are spaced alternately with whorls of a spiral groove of a second pitch. A readout apparatus comprises a light beam which is arranged to scan the grooved label and a detector which is arranged to sense the light beam reflected from the disc record surface. Light striking a grooved section of first pitch is reflected in a substantially specular direction while light striking a grooved section of second pitch is substantially scattered out of the specular direction. The detector is arranged to collect the light reflected into the specular direction.

The marking comprises a plurality of related marks, such as a bar-code marking, which are recessed through the coating and which have substantially different light reflectances than the surrounding surface. The workpiece may include an integral undercoating between the coating and the main body with marks recessed into, but not through, the undercoating. The marks may be made by selectively removing material, as by abrasion or ablation, from defined surface areas and through the coating.

An electrochromic display device includes an electrolyte and at least one transparent electrically conductive electrode. An organic insulating layer e.g. a photoresist material, is disposed between the transparent electrode and the electrolyte such that no portion of the transparent electrode is in contact with the electrolyte. The insulating layer protects the transparent electrode from deterioration so as to increase the lifetime of the transparent electrode.
