An apparatus and method for terminating crosswires on a tension focus mask. The apparatus includes a set of base segment side rails each having a length and two respective ends. A pair of square tubes attached perpendicular to the respective ends of said base segment side rails to substantially form a rectangle. Also included are a pair of massive side rails having a length and two respective ends mounted above said base segments perpendicularly to said square tubes on each of the side rapid. Beam shield is offered to the massive side rail and insulating members are sandwiched between the side rail and a bus bar. Finally, a tension mask is attached and crosswires are laid and affixed to the bus bar.

A cathode-ray tube having a luminescent screen on a faceplate panel and a tension mask assembly, wherein the assembly comprises a pair of support blades for supporting a tension mask. The tension mask has a pair of mask borders each being fixed to a respective support blade and a plurality of strands extending between the mask borders. The mask further comprises cross wires extending generally perpendicular to the strands on a screen facing side and at least one shield assembly extending between and attached to the mask borders. The shield assembly has a sheath extending along one side of the mask in contact with at least one strand and a shield attached to the cross wires of the mask in overlapping relation to the sheath.

A color cathode-ray tube 10 has an evacuated envelope 11 with an electron gun 26 therein for generating at least one electron beam 28. The envelope further includes a faceplate panel 12 having a luminescent screen 22 with phosphor lines on an interior surface thereof. A uniaxial tension focus mask 25, having a plurality of spaced-apart first metal strands 40, is located adjacent to an effective picture area of the screen 22. The spacing between the first metal strands 40 defines a plurality of slots 42 substantially parallel to the phosphor lines of the screen. A plurality of second metal strands 60 are oriented substantially perpendicular to the first metal strands 40 and are insulated therefrom across the effective picture area by insulators 62. The second metal strands 60 are attached by a glass conductor layer 68 to respective right and left first metal end strands 140 outside the effective picture area to form busbars.
摘要:
The present invention provides an improved alkali metal dispenser which is pure and free of contaminant gases, and provides for controlled releasing, delivery and recycling of the alkali metal in multiple stages in a controlled manner. The present invention also provides an alkali metal pump or getter.
摘要:
An apparatus and method for dampening vibration of a television tube in a tension mask. The apparatus include a vibration reducing assembly that is affixed between a mask frame and a busbar assembly of a tensioned mask. The vibration reducing assembly is comprised of a tension coil spring with a pin inserted in the center of the coils. As the busbar assembly or mask is vibrated, the spring pulls and releases, allowing the internal pin to rub against the coils, scrubbing away energy. The busbar assembly and the mask are formed such that their independent resonant frequencies differ greatly from one another.

The invention provides a tension mask support frame assembly having a pair of support blade members attached to a frame. The support blade members are attached to opposite sides of the frame at a central location whereby each support blade member has a pair of distal ends extending from the central attachment point. A damping scrubber is disposed in the space between the support blade member and the frame near a distal end of the support blade members. Vibrations in the tension mask are thereby reduced through the transfer of the vibrations to the frame through rubbing action of the damping scrubbers.
摘要:
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.
