摘要： This invention relates to an apparatus for production of metal powders of a low oxygen content, which are preferred as raw material powders for sintered bodies of a high toughness, according to the water atomizing method. More specifically, when a molten metal is sprayed in a limited space with use of a liquid crystal medium and cooled promptly, a metal powder results of a good moldability which has an oxygen content corresponding to 1/2 or less of the oxygen contents of metal powders prepared by conventional apparatuses and which is excellent in the size uniformity.

摘要： A directly heated cathode for electron tube having a stable electron emission characteristic is provided. The cathode comprises a base metal of Ni-W alloy consisting essentially of 20-30% by weight of tungsten, the balance being nickel and incidental impurities, said alloy being free from a reducing agent, and a layer of thermoelectron emission oxides laid directly and baked onto the flat part at the front side of the base metal. The layer of thermoelectron emission oxides is in direct contact with the flat part of the base metal.

摘要： The present cathode for cathode ray tube of directly heating type is characterized by comprising a cathode substrate body having two leg pieces extended in the same direction and a flat part connected to one end of each leg piece, prepared by shaping a flat metal plate of nickel- or cobalt-based alloy, a bonding layer having an uneven surface prepared by diffusion bonding by heating a powder layer comprising powders of alloy or mixture of nickel and cobalt formed on the flat part, to which a thermionic emission layer is to be bonded, and the thermionic emission layer, and has a very small deformation when used and a longer life.A cathode with much less deformation and much longer life can be obtained by using a cathode substrate body prepared from a flat metal plate provided with a thinner metal layer of at least one of nickel and cobalt on its surface than the flat metal plate by diffusion bonding.A cathode with much less deformation after the service for a long period and much longer life is obtained by using a cathode substrate body prepared from a flat metal plate provided with a metal layer of at least one of nickel and cobalt having a smaller thickness on its surface than that of the flat metal plate by diffusion bonding, and then applying a plastic working to the flat metal plate to a desired thickness.
