摘要： A shadow mask for a color cathode-ray tube including a first portion on which a plurality of electron beam through holes are formed; and a second portion on which no electron beam through holes are formed, the second portion surrounding the first surface portion, wherein each of the plurality of electron beam through holes includes an electron beam exit hole, each of the electron beam exit holes of electron beam through holes formed at a periphery of the fist portion near the second portion having a first length Dh in a direction facing away from the center of the shadow mask that is greater than a second length Dv perpendicular to the direction facing away from the center of the shadow mask. Therefore, a vibration generated on the shadow mask is attenuated within an elastic range of shadow mask, and thereby the shadow mask is able to endure an external shock and a permanent distortion to the shadow mask can be prevented to ensure color purity of the color cathode-ray tube.

摘要： A color selecting apparatus for a cathode-ray tube including a frame, and a mask supported in the frame with tension along a minor axis, where the mask having a rectangular hole part formed with a plurality of electron beam-passing apertures, a non-hole part surrounding the hole part, and a pair of vibration attenuating members attached at both ends of the surface of the non-hole part, facing each other along a major axis, for attenuating vibration waves which transmit along the major axis. The vibration attenuating members are made of a metal having a greater mass than the non-hole part, and attached by spot-welding so that they are away from the non-hole part by a predetermined gap at every portion except the welding points. Therefore, the vibration attenuating members serve as a damper to attenuate vibrations which are transmit in the major direction, particularly vibrations generated by the speakers.

摘要： The present invention provides a method of attaching a tension mask to a frame to achieve desired tensions at a plurality of locations across the mask, wherein the frame has two opposite sides between which the mask is to be attached. Specific forces are applied from each of a plurality of separate actuators at positions, along each of the two opposite sides of the frame, that affect the mask tensions respectively at the plurality of locations across the mask. Each of the actuators is individually controlled to apply a specific force to a frame side that is directly related to the desired mask tension required at a particular mask location. While the specific forces are applied by the actuators, the mask is attached to the two opposite sides of the frame. Thereafter, the forces on the sides are released.

摘要： In order to prevent doming effect in a shadow mask of a color cathode ray tube caused by thermal expansion of the shadow mask structure produced by heating of the shadow mask due to impingement of the electron beam thereon, the shadow mask is provided with a skirt portion along at least one side thereof. The skirt portion includes a long projection portion where the shadow mask is welded to the frame, an adjacent inclined portion which decreases in length in a direction away from the projection portion. Further, a short portion is disposed therebetween the inclined portion. The inclined portion decreases in length linearly or non-linearly.
