Title: Cardlike information recording medium
Inventor: IMATAKI HIROYUKI
IPC: G11B7/24012
Filed: 1993-10-22
Abstract: PURPOSE:To reduce warpage, deformation due to variations in a temperature, a humidity, a density by providing a layer having high rigidity in a long side direction of a cardlike information recording medium for recording/reproducing information. CONSTITUTION:A layer 14 having high rigidity only in a long side direction of a cardlike information recording medium is provided in the medium for recording/reproducing information. For example, glass fibers are aligned in a sheetlike state in parallel as a rear board, and a vinyl chloride sheet is press injected thereto, thereby manufacturing a rigid sheet 14. A 0.4mm PMMA transparent resin board 11 having an optically recording layer 12 is adhered to the board through an adhesive layer 13 in such a manner that a long side of a card is parallel to a fiber direction, and punched in a size of a card to obtain a cardlike optically recording medium. That is, since it can be reversibly deformed against an impact from an exterior during carrying, an irreversible deformation, a crack, peeling, etc., scarcely occur. Since rigidity of a long side direction of a recording/reproducing direction is high, stable recording/ reproducing can be executed.

Title: Image sensor
Inventor: WATANABE HIROYUKI
IPC: H01L23/29
Filed: 1986-11-07
Abstract: PURPOSE:To seal and fix an image sensor by using plural kinds of resins in mounting the titled image sensor formed into one sensor from plural image sensors adhered by adhesives while protecting joints sufficiently. CONSTITUTION:The hardness (JIS A) of a mold resin 5 is over 50, preferably over 80 and a mold resin 6 has the hardness of below 50, preferably below 20. The mold resin 5 limits the movement between two image sensors 1 to prevent the destruction of the adhesives at the joint and a bonding wire 2 is sealed and fixed by the resin 5. Since the bonding wire 3 is placed at both ends of the image sensor 1, a force due to the difference from thermal expansion between the image sensor 1 and the substrate 4 is not neglected. Then the parts other than the joint use a low stress mold resin 6 for sealing and fixing.
