  • Photovoltaic generator
    Patent number: 4244750
    Abstract: A basic photovoltaic stack is constituted by a semiconducting layer interposed between a layer forming an ohmic contact and a layer forming a Schottky contact. A second photovoltaic stack having the same structure as the basic stack is formed on this latter and includes one of the layers forming an ohmic or Schottky contact. The layer or layers forming an ohmic contact are connected together so as to constitute a first output terminal of the photovoltaic generator. The layer or layers forming a Schottky contact are connected together so as to constitute a second output terminal of the generator.

  • Evaporation source for vacuum deposition
    Patent number: 4113978
    Abstract: Evaporation source for vacuum deposition, comprising a refractory crucible provided in its outer surface with conducting members traversed by an electric current and able to raise the crucible temperature by Joule effect, in which the said outer surface is coated, prior to fitting the conducting members, with a thin intermediate coating layer which does not react with the crucible but which is in intimate contact with the latter.A particular application is the vacuum heating to elevated temperature of crucibles.

  • Magnetic circuit having low reluctance
    Patent number: 3961299
    Abstract: A magnetic circuit which exhibits low reluctance on the path of a magnetic flux and comprises at least one anisotropic thin film formed of an iron-nickel-chromium alloy through which said magnetic flux passes in the hard direction of magnetization of the film.

  • Integrated magnetic head having alternate conducting and insulating layers within an open loop of two magnetic films
    Patent number: RE29326
    Abstract: The open-loop magnetic circuit of an integrated magnetic head for reading and/or writing is made up of two magnetic films which are joined together at one end, the other end being placed in proximity to the writing and/or reading surface and substantially at right angles thereto. In order to form the electric winding for writing and/or reading, the magnetic head comprises within said loop and in an alternate arrangement a succession of electrically conducting and electrically insulating film layers which are at least partially superposed in a direction substantially at right angles to the plane of the two magnetic films.
