  • Patent number: 10096462
    Abstract: A substrate processing method and apparatus for preventing evaporation of an anti-drying fluorine-containing organic solvent from a substrate during transportation of the substrate into a processing container and can prevent decomposition of a fluorine-containing organic solvent in the processing container. A substrate, the surface of which is covered with a first fluorine-containing organic solvent, is carried into a processing container. The first fluorine-containing organic solvent is removed from the substrate surface by forming a high-pressure fluid atmosphere of a mixture of the first fluorine-containing organic solvent and a second fluorine-containing organic solvent, having a lower boiling point than the first fluorine-containing organic solvent, in the processing container e.g. by supplying a high-pressure fluid of the second fluorine-containing organic solvent into the processing container.

  • Publication number: 20180031833
    Abstract: The problem addressed by the present invention is to provide a head-up display device suitable for a curved windshield in a head-up display device provided with a combiner and a cover wherein the cover moves in the longitudinal direction of the vehicle. A front part of a guide rail extending in the longitudinal direction of the vehicle is curved downward. A cover, which moves along this guide rail, is moved by a drive link and a driven link. Because the curved guide rail is used, the dimension of a head-up display device in the longitudinal direction of the vehicle can be reduced, a large inclined surface can be provided on the upper front part of a housing, and the head-up display device can be placed close to a curved windshield.
