摘要： A correction lens disposed between the exposure light source and a glass panel provided with a shadow mask at the exposure step of manufacturing a color television CRT and adaped to compensate for the tendency of the phosphor stripes being formed in a wavy configuration. The correction lens has such a characteristic that, when the light source is observed through the correction lens at the side of the shadow mask, the light source is viewed as displaced in appearance toward the correction lens by a certain constant distance on the optical axis independently of the viewing angle, whereby the image of a linear light source or the linear moving path of a point source of light is made to extend substantially in parallel with the length of the slot of the shadow mask.

摘要： In a cathode-ray tube provided with a direct-heating type cathode, a transformer through which the cathode is heated is disposed within the bulb of the cathode-ray tube. This improvement eliminates the instability of heating due to the contact resistance caused between the base pins of the cathode-ray tube to which the terminals of the cathode are connected and the socket pins to which the base pins are fitted.
