摘要:
A color selecting electrode assembly for color cathode ray tubes which includes an apertured grill composed of fine-strand grids, a frame over which the aperture grill is stretched and which provides a tensioning force to the apertured grill, and a supporting structure body which is mounted at one end to said frame and engages the other end with the panel side wall of a color cathode ray tube so as to support said frame, wherein the wall thickness of said apertured grill is not greater than 0.032 mm. To assure the characteristic frequency of the aperture grill, it becomes unnecessary to manufacture individually frames having rigidities corresponding to respective slit pitches of the apertured grill. The frame can be a general purpose one (i.e., one used in common with others), thereby allowing the manufacture to be simplified. Further, the suppoting member can be also used in common with others, thereby allowing the design to be simplified.

A color selecting electrode assembly for color cathode ray tubes includes: an aperture grill having thin slits; a frame over which the aperture grill is stretched; and supporting members in which a fixing portion at one end is attached to the frame and an engaging portion at the other end is engaged with a panel pin provided on a panel side wall so as to support the frame. An elastic portion of the supporting members is arranged in such a manner that boundary portions of the elastic portion with the fixing portion and the engaging portion become parallel to a longitudinal-direction of the slits. An engaging hole bored in the engaging portion is provided at such a position that the engaging hole intersects with an imaginary extension plane in which a joining portion of the frame and the aperture grill is extended in a direction parallel to a tube axis of a color cathode ray tube.
摘要:
An electronic apparatus receiving therein a plurality of electronic equipments, each of which has heat generating electronic parts and which are spaced from one another, has caused a problem that amounts of an air flowing into wind paths between the respective electronic equipments involve scatter. To solve the above-mentioned problem, the electronic apparatus is constructed such that the pressure-loss adjusting plates 12 are provided on the fins 5 facing those wind paths of large inflowing air volume among the wind paths formed between the respective electronic equipments 2 received in the rack 1.
摘要:
An electronic apparatus containing in a rack a plurality of electronic equipments each having heat generating electronic parts, and provided with fins for dispersing heat from the electronic equipment, involves a problem of low heat radiating efficiency. Providing a wind-path separation covers formed in a manner to cover top portions of the fins increases an amount of an air flowing into the fin-inbetween wind paths.
