Abstract: The present disclosure provides a medical instrument with a coating that provides excellent lubricity when wet. The medical instrument possesses a coating including a wet lubricating film with high peel durability and anti-eluting properties. In embodiments, an intermediate film made of bisphenol A type epoxy resin is coated on a base material of a medical instrument made of metal, and a wet lubricant coating produced by alkaline processing of a polymer alloy containing a methyl vinyl ether maleic anhydride copolymer and a polyether block amide is then applied thereto. Methods for making these medical instruments are also provided.

Abstract: When an organic EL device 9 is turned ON, an image of a design 2b of a design film 2 formed by light L2 emitted when light L1 generated in an organic layer 7 is transmitted through the design film 2 and a transparent member 3 and then enters a half mirror layer 4 and an image of the design 2b of the design film 2 formed by light L5 emitted when the above-mentioned light is reflected by the half mirror layer 4 and then reflected by a reflection electrode layer of the organic EL device 9 are shifted to each other in a horizontal direction without a loss. As a result, the design 2b drawn on the design film 2 comes up and is seen in three dimensions. When the organic EL device 9 is turned OFF, the light emission from a surface light-emission apparatus 1 stops so that the apparatus serves as a simple mirror by virtue of the half mirror layer 4.
