  • Patent number: 8043668
    Abstract: Provided is a method for depositing a fluorine-doped silicon oxide film on the surface of a substrate made of a material comprising at least 50 mass % of an ethylene/tetrafluoroethylene copolymer. This method comprises flowing a mixed gas into between electrodes, exposing the mixed gas to electric power applied between the electrodes so that the electrical power density between the electrodes becomes from 0.5 to 1.1 W/cm3 to cause discharge, and forming plasma of the mixed gas and depositing the fluorine-doped silicon oxide film on the surface of the substrate. In this method, the mixed gas for forming the fluorine-doped silicon oxide film comprises silicon tetrafluoride, oxygen and a hydrocarbon, the atomic ratio of oxygen atoms to carbon atoms (O/C) is from 1 to 10, and the atomic ratio of oxygen atoms to silicon atoms (O/Si) is from 1.7 to 25 in the mixed gas.

  • Patent number: 7296850
    Abstract: A vehicle roof structure is provided with a roof panel dampening bracket which adds mass to a roof panel in order to control the resonance frequency of the roof panel. The dampening bracket has a base part, a mass adding part and a connecting part. The base part is joined to a roof bow. The mass adding part is joined to the undersurface of the roof panel by an adhesive agent in at least two points in both end parts of the vehicle in the front to aft direction. The connecting part extends in the front to aft direction of the vehicle to interconnect the base part and the mass adding part. The connecting part has at least one bent part that extends in the lateral direction of the vehicle.

  • Publication number: 20070228617
    Abstract: To provide an ethylene/tetrafluoroethylene copolymer molding, and a method for producing the ethylene/tetrafluoroethylene copolymer molding in which the operation for the production is simple, and the surface can be highly hydrophilized. An ethylene/tetrafluoroethylene copolymer molding is produced by conducting discharge treatment of a surface of a molding to be treated, under reduced pressure in a mixed gas containing oxygen and a hydrocarbon, said surface being made of a material comprising an ethylene/tetrafluoroethylene copolymer as the main component.

  • Publication number: 20070202340
    Abstract: To provide a process for producing a fluorocarbon film, which is capable of constantly forming a fluorocarbon film excellent in durability and functionality. The process for producing a fluorocarbon film of the present invention is a process for producing a fluorocarbon film at least a part of which is chemically bonded to a substrate surface, and is characterized by conducting, in sequence, step (a) for applying plasma to a substrate surface in a continuous or pulse manner to form active points on the substrate surface and step (b) for applying plasma to the substrate surface in a continuous or pulse manner in the presence of a gas of a fluorocompound represented by the formula CxFy and/or CxFyOz under such a condition that active species impinge on the substrate surface at a relatively lower collision energy than in step (a).
