  • Publication number: 20130146860
    Abstract: The present invention provides: a method of manufacturing a gas barrier film, which is manufactured at high productivity, and has extremely high gas barrier performance and stability thereof with time, excellent surface smoothness and bending resistance, and high durability; a gas barrier film obtained using the method; and an organic photoelectric conversion element using the gas barrier film. In the method, after forming a coated layer by applying a coating liquid containing polysilazane to a substrate, a gas barrier layer is formed by applying vacuum ultraviolet light to the coated layer surface thus formed. The method is characterized in that the coated layer is irradiated with the vacuum ultraviolet light, while drying the solvent in the e coated layer.

  • Publication number: 20090122359
    Abstract: An object of the invention is to provide an reading glass, an reading apparatus comprising the reading glass and an image forming apparatus comprising the reading apparatus, the reading glass which reduces attenuation of a light, which is of a light source or reflected by a document, passing through the reading glass, reduces attachment of paper powder and the like, and thus can provide high quality images. The present invention is characterized in that a glass member positioned between the document and the light source of the reading apparatus for optically reading the document has an antireflection function.

  • Publication number: 20080138612
    Abstract: The object of the present invention is to provide: a glass member characterized by excellent friction resistance property, and antifouling property; a reading glass wherein, when this glass member is used as the reading glass of a scanner or a copier, toner, dust or adhesive does not easily deposit on the reading glass, with the result that deterioration in the copied image quality such as black spots or black streaks can be avoided; and a scanner or a copier wherein the glass is used. The glass member including a glass substrate including a fluorine containing film coated directly, not through any other layer interposed, on at least one surface of the glass substrate, wherein an element composition of the fluorine containing film is characterized in that a content of fluorine atoms exceeds 30 atomic percent, and an atomic ratio of oxygen atom to fluorine atom (O/F) is between 0.2 and 1.0.
