The invention relates to a mold having an irregularly uneven surface structure in which an average inclination angle is from 20 to 80 degrees; an optical article having an irregularly uneven surface structure in which an average inclination angle is from 20 to 80 degrees; a method for manufacturing an optical article having an irregularly uneven surface structure by transferring an uneven structure of a mold; a transparent substrate for a surface light emitter which uses an optical article having an irregularly uneven surface structure; and a surface light emitter having a transparent substrate for a surface light emitter.

The invention provides a method of making ophthalmic lenses with an enhanced quality and enhanced yield achieved by using molds having been treated on back surface of mold with corona discharge technique. The method comprises the steps of obtaining a mold for cast-molding contact lenses from a lens formulation, wherein the mold comprises a first mold half having a first molding surface and a first back surface, a second mold half having a second molding surface and a second back surface, wherein when the first and second mold are configured to receive each other such that a lens forming cavity is formed between the first molding surface and the second molding surface and applying a corona discharge on one of the first and second back surfaces so that the molding surface of the mold with the treated back surface has an average water contact angle smaller than the molding surface of the mold with untreated mold by about 0.1 degrees to about 6 degrees.

A method for manufacturing a member with a concave-convex pattern includes: forming a first film on a concave-convex pattern formed on a surface of a mold; forming a second film on a base member; joining the first film and the second film by overlapping the mold with the base member; and releasing the mold from the first film joined to the second film. A method for manufacturing a functional member with a concave-convex pattern is provided.

A disclosed digital media device operational at user premises to receive media signals from a media source for presentation via endpoint devices such as a television display. The digital media device can include gateway and digital media management functionality and can be referred to as a gateway and digital media device. The device offers application services obtained over a wide area network and a user premises network. The digital media device may form a composite signal from the media signal and application service information, for example, for a composite audio and/or video signal for television type presentation to the user. The digital media device may receive a selection signal based on the presentation, for transmission to the application service provider device or to the media source. The media device also offers a GUI presenting a moveable arrangement of icons for selectively accessing application services.

Apparatuses and methods are described for distributing gas which may be applicable in the field of polymer oxidation and melt curtain ozonation in particular. Ozone applicators and other features of ozonation apparatuses, which may be used separately or in combination, are also described.

A method for manufacturing a joined body according to an embodiment of the present disclosure is a method for manufacturing a joined body in which composite materials in which fibers are impregnated with resins are heated and joined to each other. The method includes: a step of aligning the composite material with each of a plurality of molding dies, heating the molding dies, and semi-curing the resins of the composite materials; and a step of joining the composite materials to each other by combining and heating the molding dies with which the composite materials are aligned after semi-curing the resins of the composite materials. The molding dies used when semi-curing the resins of the composite materials and the molding dies used when joining the composite materials to each other are the same.

A joined body includes: a first compact that includes a fiber-reinforced resin and a fiber exposure portion where a fiber of the fiber-reinforced resin is exposed, the fiber exposure portion being formed on at least a part of a surface of the first compact; a second compact that is joined to the first compact at the fiber exposure portion of the first compact; and a joint portion that is interposed between the fiber exposure portion of the first compact and the second compact.
