摘要： The present invention improves the stability among the qualities of the electron tube cathodes in which the barium scandate is dispersed and contained in the alkali earth metal oxide layer provided on the surface of the base metal, by making the shape and average particle size of the barium scandate similar to those of the carbonate used to form the alkali earth metal oxide, and it avoids the deterioration of the electron emission property for a long time, by setting the concentration of the barium scandate in the alkali earth metal oxide layer to zero at the position close to the surface of the base metal.

摘要： A color cathode ray tube has an electron gun in its neck portion. Its focus electrodes and anode are fixed by two insulating support rods. A voltage-dividing resistor is disposed in the vicinity of one of the insulating support rods for producing an intermediate voltage applied to a first one of the focus electrodes adjacent to the anode by dividing an anode voltage. The voltage-dividing resistor includes an insulating film, a resistance pattern, an insulating substrate, and a second film containing an oxide of transition metal, in the order named from the insulating film toward the inner wall of the neck portion. A metal conductor surrounding the voltage-dividing resistor and the one of the insulating support rods is fixed to a second one of the focus electrodes which is disposed upstream of the first one of the focus electrodes in a path of the electron beams.

摘要： A dark heater is produced by a method which comprises coating the first coating layer made of an insulating material with a suspension containing heat-resistant particles having a high thermal emissivity, such as W particles, while 0.5 to 1.5 wt. % of a volatile matter such as water remains in the first coating layer to form a dark coating layer. Since the suspension having a low viscosity can be used, the thickness of the dark coating layer can be made highly uniform and the emission characteristics of the heater can be stabilized.
