摘要： A large number of oxide cathodes are aligned in an oxide cathode aligning/fixing jig which is formed in a plate shape composed of an upper member and lower member. The horizontal positions of the oxide cathodes fit in the cut holes are fixed by the upper member. The height of the upper surface of the metallic body of each of the oxide cathodes, on which a carbonate paste is to be printed is fixed by the lower member of the jig. By performing the screen printing for the metallic bodies in a state where the upper surfaces thereon are at equal heights, misalignment in printing pattern or variation in the thickness of the printed carbonate films can be suppressed. Thus, the screen printing can be carried out for the large number of oxide cathodes at a time at precise positions and with a uniform thickness of the carbonate layer.

摘要： A cathode for an electron tube including a base body having nickel as a major component and including at least one kind of reducing agents, a metal member in a layer-like shape, which has as a major component a metal provided with a reducing power equivalent to or smaller than a reducing power of the at least one kind of reducing agents included in the base body and larger than a reducing power of nickel and which is formed on faces of the base body, an electron emitting substance layer formed by depositing alkaline earth metal oxides including barium on the metal member, wherein the metal member is formed on the faces of the base body such that the base body is restrained from deforming by thermal stresses of intermetallic compounds formed at portions of the base body bounded with the metal member.
