20130010253	POLARIZING LENS MADE OF AROMATIC POLYCARBONATE - The present invention relates to a polarizing lens molded by inserting a polarizing sheet bent into a sphere or an asphere after having an aromatic polycarbonate sheet bonded via an adhesive layer to both surfaces of a film with polarized nature into a mold, and injecting aromatic polycarbonate, wherein heat treatment at a temperature not less than a temperature of 50° C. lower than the glass transition point and less than the glass transition point for an appropriate time has been performed after injecting aromatic polycarbonate to approximate a designed value of the lens curvature.	01-10-2013
20130070196	POLARIZING LENS CONSTITUTED OF AROMATIC POLYCARBONATE - Provided is a polarizing lens which is excellent especially in terms of impact resistance, appearance, and prevention of eye strain and which has high precision of the surface shape. The polarizing lens is formed by laminating a sheet of an aromatic polycarbonate through an adhesive layer to each surface of a film having polarizing properties, curving the resultant laminate so as to impart spherical or aspherical surfaces thereto to obtain a polarizing sheet, inserting the polarizing sheet into a mold, and injecting an aromatic polycarbonate, wherein the polarizing sheet is obtained through the laminating so that the stretch axis of one of the aromatic-polycarbonate sheets is perpendicular to the absorption axis of the film having the polarizing properties.	03-21-2013

20090123876	Optical disc and method of producing the same - An optical disk has a first and a second intermediate disk structure. The first structure includes at least a first transparent substrate, a first recording layer, and a first reflective layer. The first substrate has a first surface and a second surface. The first surface is a beam incidence surface for a laser beam in recording or reproduction of data. The second surface has a first concave section and a first convex section formed thereon. The first recording layer and the first reflective layer are stack in order on the second surface via the first concave and convex sections. The second structure includes at least a second substrate, a second reflective layer, and a second recording layer. The second substrate has a second concave section and a second convex section formed thereon. The second reflective layer and the second recording layer are stack in order on the second substrate via the second concave and convex sections. The first and second structures are bonded to each other so that the first reflective layer faces the second recording layer, the first concave section becomes closer to the beam incidence surface than the first convex section does, and the second concave section becomes closer to the beam incidence surface than the second convex section does. The first recording layer has a first data-storage area on the first concave section. The second recording layer has a second data-storage area on the second concave section. Each of the first and second convex sections has at least one pre-pit formed thereon. The pre-pit carries auxiliary information related to the data to be recorded or reproduced.	05-14-2009

20150092526	MULTI-LAYER OPTICAL RECORDING MEDIUM AND OPTICAL RECORDING DEVICE - A multi-layer recording medium is constituted by guide layer-equipped optical disks having a plurality of recording layers and guide layers are integrated by bonding said disks to one another so as to produce a double-sided disk, both sides of which may be used for recording. With regards to the lead-in areas for the guide layers of the guide layer-equipped optical disks for both sides, single-sided disks and double-sided disks are identified, and face-management information for identifying the side surfaces in the case of a double-sided disk is recorded in advance in said lead-in areas using wobbles or the like. As a result, the likelihood of the occurrence of defective products caused by the inability to read the face information can be reduced.	04-02-2015
