Abstract: A color selection apparatus for a cathode ray tube includes a tension mask including a plurality of electron beam passage apertures; and a frame including a pair of support members provided along opposite sides of the tension mask and applying a tensile force to the mask, and a pair of elastic members extending from one support member to the other at ends of the same, the elastic members maintaining a predetermined distance between the support members. Each of the elastic members is hollow and includes a base that is substantially parallel to the tension mask, with extensions formed substantially perpendicular to the base at both ends thereof, and bending portions integrally formed between the base and the extensions. Reinforcing elements are formed in proximity to the bending portions to increase the strength of the elastic members in the area of the bending portions.

Abstract: A color selection apparatus for a cathode ray tube. A mask frame having a pair of supporting members is disposed in parallel and spaced away from each other. A pair of elastic members is disposed between and coupled to the supporting members. A tensioned mask is coupled to the supporting members and is provided with a plurality of beam-passing apertures. A spring assembly includes a hook having a frame fixing part fixed on the mask frame and a spring fixing part and a spring fixed to the spring fixing part. The hook has a cut-away portion defined by cutting a portion of the frame fixing part. The cut-away portion forms a welding portion for welding the hook to the mask frame.

Abstract: A shadow mask/frame assembly for a color CRT includes a shadow mask including a hole portion having a predetermined curvature where a plurality of electron beam passing holes are formed and a bending portion extending from the edge of the hole portion by being bent at a predetermined angle, and a frame including a skirt portion coupled to the bending portion of the shadow mask, a flange portion extending from the skirt portion by being bent at a right angle thereto, a connection portion extending downward from the flange portion, and an extension portion extending from the connection portion, parallel to the flange portion.
