    摘要: Disclosed is a shadow-mask type color cathode-ray tube comprising a faceplate having a curved inner surface which prevents degrouping and a substantially flat outer surface. In this color cathode-ray tube, the resolution is not deteriorated in the peripheral portion and an inespensive flat material is usable as a glass plate provided with a reflection reducing coating or a touch panel attached to the outer surface of the faceplate. Since a shadow mask supported with a tension applied thereto is usable, the positional deviation of the apertures due to the expansion of the shadow mask during operation is prevented.

    摘要: An impregnated cathode which has a portion where no electron emissive material is present on the surface layer of the cathode base body that is to be welded, in order that the cathode base body impregnated with the electron emissive material, a cup and a cathode sleeve can be firmly welded together. The cathode base body which has no electron emissive material on the surface layer is obtained by washing the cathode base body in a solvent which is capable of dissolving the electron emissive material. Using this cathode base body, the impregnated cathode is fabricated.
