Patents by Inventor Christian Bianchin

Christian Bianchin has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Transparent material having electrical conductivity which is dependent on the dose of optical radiation received
    Patent number: 4421677
    Abstract: The transparent material is constituted by a thin film of a substoichiometric amorphous oxide of molybdenum or tungsten, the electrical conductivity of the material being dependent on the dose of optical radiation which it has received. The potential applications of the material include the fabrication of memory devices and image converter devices.
    Type: Grant
    Filed: June 28, 1978
    Date of Patent: December 20, 1983
    Assignees: Commissariat a l'Energie Atomique, Agence Nationale de Valorisation de la Recherche (ANVAR)
    Inventors: Christian Bianchin, Alain F. Deneuville, Philippe Gerard
  • Electrochromic and photochromic material and a method of fabrication of said material
    Patent number: 4096087
    Abstract: The material is constituted by a sub-stoichiometric amorphous oxide doped by hydrogen corresponding to the formula MO.sub.x H.sub.y, where M is a metal of group VI such as tungsten, with 2.6 < x < 2.8 and 0.3 < y < 0.6. The method of fabrication of the material involves a cathodic reactive sputtering operation which is carried out by subjecting a target having a base of a metal of group VI such as tungsten or a metal oxide to an ion bombardment in the presence of a reactive gas which consists in particular of oxygen and hydrogen.
