  • Structural component made of hard material for a wristwatch
    Patent number: 6746148
    Abstract: The invention concerns a structural component made of hard material for a wristwatch, characterized in that it includes a hole fitted with an inner threading which is integral with said component, said threading being directly obtained by injection and thus without removing any material of said component for example by machining.
    Type: Grant
    Filed: August 26, 2002
    Date of Patent: June 8, 2004
    Assignees: Montres Rado SA, Comadur S.A.
    Inventors: Michael Bach, Christophe Guerry, Olivier Bucher

  • Method of manufacturing semiconductors from homogeneous metal oxide powder
    Patent number: 5322642
    Abstract: A method of manufacturing metal alloys to obtain a homogeneous powder made up of oxides of the metals and applications thereof to the manufacture of semiconductors and superconductors comprises, after placing the various metals selected in a crucible, melting the metals in a neutral or reducing atmosphere while stirring the liquid to homogenize it, recovering the liquid alloy, spraying the alloy obtained to form homogeneous powder particles of determined particle size, and oxidizing the particles. It applies to the manufacture of zinc oxide-based varistor type semiconductor ceramics and to the manufacture of superconductor products or positive or negative temperature coefficient thermistors.
