Abstract: An inner shield for a cathode ray tube comprising a plurality of rectangular segments parallel to the tube axis; a flange joined to each of the rectangular segments and bent in a right angle for mounting on a mask frame; a trapezoid portion joined to each of the rectangular segments, being arranged slantwise along an inner circumference of a funnel; and a pair of holes formed in the two adjacent trapezoid portions to decrease a deflection in a East-West direction of an electron beams. Since an undesirable affection on the electron beams caused by the earth magnetic field is decreased, a pin-cushion distortion and barrel distortion of the electron beams are highly decreased.

Abstract: A dispenser cathode comprises an electron emissive material including at least one selected from the group consisting of Ba and Ba oxide, a porous metal base body having a plurality of diffusing cavities and positioned on the electron emissive material and an alloy thin film layer consisting of scandium tungstate and tungsten which is disposed between the electron emissive material and the porous metal base body. Instead of the alloy thin film, a pellet containing scandium tungstate may be interposed between said electron emissive material and the porous metal base body. The activation aging time of the dispenser cathode of the present invention is greatly shortened as compared with the conventional dispenser cathode, and the damage of Sc by ion bombardment is prevented, and thus the stable thermoelectron emission can be obtained.
