A method of manufacturing a cathode ray tube, the color selection mechanism, as well as color selection mechanism for frame

摘要

A method of manufacturing a color cathode-ray tube which aimed to improve the temperature drift of the beam landing, color selection mechanism, as well as the present invention provides a color selection mechanism for frame. Has a frame-shaped frame made of elastic applying member and a pair of (42, 43) support members of the pair and (44, 45), the present invention, the color of the support members a pair (42, 43) between the I make up a color selection mechanism which is stretched is (49) for selection mask. Further, those positioned plate surface so that their faces and formed by a flat plate material, elasticity imparting pair of members (44, 45) of cross-section (42, 43) support members of the pair as the frame which is arranged to be tilted L-shape, to use a combination of the (42, 43) and the support member (44, 45) the two elastic applying member. The present invention to construct a color cathode-ray tube with a color selection mechanism like this.
