  • Rotary anode for an x-ray tube and an x-ray tube having such anode
    Patent number: 4731805
    Abstract: A rotary anode for an X-ray tube is in the form of a disc (1) the surface of which has, at least partially, a blackening coating (2). The latter is in the form of a sintered porous composition of titanium grains, mainly of the dendritic structure, of a size from 0.5 to 150 .mu.m, and at least one high-melting metal having a melting point above 2500.degree. C., the quantity the high-melting metal in the composition being from 5 to 60% by mass.
    Type: Grant
    Filed: January 28, 1986
    Date of Patent: March 15, 1988

  • Grid-like electrode for electronic components and process for making same
    Patent number: 4469984
    Abstract: A grid-like electrode for electronic components having its grid portion made of fibrous carbon threads bonded by means of the coke of an organic polymer. The grid-like electrode is made by impregnation of each fibrous carbon thread with a liquid organic polymer containing at least 20% by weight of carbon. Then a grid-like electrode is shaped from these threads and subjected to heating until the polymer is irreversibly cured, followed by heating of the polymer to cause pyrolysis thereof to a glossy carbon state.
