Abstract: An object of the present invention is to provide a gas barrier laminated material which can be produced through a simple and easy process, and which can achieve stable gas barrier properties even at high humidity. The present inventors have made a gas barrier laminated material having a metal layer (A) formed by a vapor phase thin film formation method and a layer (B) formed from a compound having a carboxyl group in the structure thereof, wherein the metal layer (A) and the layer (B) are laminated, and thus can achieve a gas barrier laminated material which can be produced through a simple and easy process, and which can achieve stable gas barrier properties even at high humidity, and have solved the problems.

Abstract: A polyester resin composition according to the present invention includes a polyester polyol having a glycerol skeleton and a curing agent, wherein 5 percent by mass or more of glycerol residue of the polyester polyol is contained in the polyester resin composition. The resin composition can provide an adhesive exhibiting an excellent adhesive force. The adhesive has a gas barrier property or a water vapor barrier property and, therefore, a gas barrier or water vapor barrier film can be provided by using the adhesive.

Abstract: An optical disc unit is disclosed, comprising a turntable on which an optical disc is placed, an optical pickup, guide shafts for guiding the optical pickup radially of the optical disc, first and second support members, as well as third and fourth support members, for supporting the guides shafts respectively, the turntable, the optical pickup, the guide shafts, and the first to fourth support members being disposed on a chassis, the second and fourth support members being respectively provided with pawl pieces spaced a predetermined gap from end portions of the guide shafts. Near the second and fourth support members are disposed adjust screws for adjusting the height of end portions of the guide shafts, as well as torsion coil springs for urging the guide shafts elastically. When the above end portions of the guide shafts are displaced away from upper end faces of the adjust screws, the displacement is restricted by the pawl pieces of the second and fourth support members.

Abstract: There is provided an optical device in which a neutral position setting for each of the adjustment screws can be carried out easily and accurately while its workability is being superior and its cost is not being increased. There are arranged on a chassis formed by a sheet metal, a spindle motor on which a turntable for use in mounting an optical disk D is attached, an optical pickup, guide shafts for guiding the optical pickup in a radial direction of the optical disk D, the first and second supporting members and the third and fourth supporting members for supporting both ends of the guide shafts, and adjustment screws for moving a height position of one end of the guide shaft and the height positions of both ends of the guide shaft, and the chassis is provided with resin fixing members having fixing surfaces to attach and fix the spindle motor and resin reference members having reference planes within the same plane.
