  • Patent number: 10072331
    Abstract: A formation method of a silicon film which contributes to improvements in cycle characteristics and an increase in charge/discharge capacity and can be used as an active material layer is provided. In addition, a manufacturing method of a power storage device including the silicon film is provided. The formation method is as follows. A crystalline silicon film is formed over a conductive layer by an LPCVD method. The supply of a source gas is stopped and heat treatment is performed on the silicon film while the source gas is exhausted. The silicon film is grown to have whisker-like portions by an LPCVD method while the source gas is supplied into the reaction space. A power storage device is manufactured using, as an active material layer included in a negative electrode, the silicon film grown to have whisker-like portions.

  • Patent number: 9988713
    Abstract: A method for preparing a device having a film on a substrate is disclosed. In the method, a film is deposited on a polymeric substrate. The film includes at least one metal. A metal in the film is converted to a metal oxide using microwave radiation. One example device prepared by the method includes a polyethylene napthalate substrate and a film on the substrate, wherein the film includes a semiconducting copper oxide and silver as a dopant.

  • Patent number: 9945507
    Abstract: An applicator machine and a process for heating and coating a section of pipeline. The applicator machine includes a frame configured to rotate about a section of pipeline to be heated and coated, rotating means operable to rotate the frame, and coating material applicators induction coils and radiant heaters mounted on the frame and rotatable therewith. The induction coil is configured to heat a section of pipeline adjacent to the induction coil to a coating material application temperature. The radiant heaters are configured to heat factory-applied coatings. Each coating material applicator sprays coating material through an aperture in a respective induction coil. The applicator includes an enclosure configured to surround a section of pipeline and provision for evacuating and collecting waste coating material. The coating material applicator may be configured to spray powder coating material, such as fusion bonded epoxy powder material and/or chemically modified polypropylene powder material.

  • Patent number: 9920431
    Abstract: A method of preparing a substrate to receive a metal coating deposited by thermal spraying, the method including the following steps: a) depositing a layer of adhesive on the zone to be coated, the layer having a uniform thickness greater than 10 ?m and less than 100 ?m; b) before the adhesive dries, cold spraying a metal powder onto the zone to be coated, so that powder particles become embedded at least in part in the layer of adhesive; and c) drying the adhesive in which the powder particles remain held captive, thereby forming an undercoat suitable for receiving a metal coating deposited by thermal spraying. The method is applicable to protecting the leading edges of fan blades.

  • Patent number: 9923200
    Abstract: A method for making a sulfur-graphene composite material is provided. In the method, an elemental sulfur solution and a graphene dispersion are provided. The elemental sulfur solution includes a first solvent and an elemental sulfur dissolved in the first solvent. The graphene dispersion includes a second solvent and graphene sheets dispersed in the second solvent. The elemental sulfur solution is added to the graphene dispersion, a number of elemental sulfur particles are precipitated and attracted to a surface of the graphene sheets to form the sulfur-graphene composite material. The sulfur-graphene composite material is separated from the mixture.
