摘要： A method of making a plurality of masks for a mask-focusing color picture tube is described. A plurality of apertured flat masks are aligned and stacked. The stacked flat masks are contacted by magnetic force and welded together. The welded flat masks are pressed into a predetermined curved shape at the same time. Next, the welded portions are cut off to separate each mask.

摘要： A method for manufacturing a mask for a color CRT. The mask comprises a plurality of mask members having a number of apertures for passing electron beems, and being spaced apart. The mask is produced by the steps of bringing the mask members into tight contact with an insulator interposed between their peripheries; fixing them by an adhesive; press forming the entire composite; melting the adhesive; and shifting apart and fixing the mask members at a predetermined distance.

摘要： A beam index color cathode ray tube is provided with a screen arranged on the inner surface of a face plate portion and an electron gun arranged in a neck portion thereof. This screen comprises phosphor stripes and index stripes. The electron gun comprises at least a cathode and two electrodes forming a focusing lens. The focusing lens of the electron gun is formed between at least two electrodes provided with transversely elongate openings having their direction of elongation in the width direction of the phosphor stripes or index stripes.
