Title: Id card and id booklet having said id card
Inventor: OBAYASHI KEIJI
IPC: G03D15/06
Filed: 1988-05-30
Abstract: PURPOSE:To effectively prevent forgery and modification and to obtain a high- quality product, by a method wherein, when a thermoplastic film is laminated on a thermoplastic resin of an image-recorded medium to be thermally fused thereto, a difference in solubility parameter between the thermoplastic resin and the thermoplastic film is specified. CONSTITUTION:An image-recorded body is obtained by recording an image in a layer of a thermoplastic resin (b) and/or on the thermoplastic resin (b) provided on a heat-resistant film substrate (a). On the thermoplastic resin (b), a thermoplastic film (c) is laminated to be thermally fused thereto, and an ID card is produced. At this time, a difference in solubility parameter between the thermoplastic resin (b) and the thermoplastic film (c) is specified to be not more than 1.0. When the thermoplastic resin (b) and the thermoplastic film (c) in this range are fused to each other under heat, they can be fused at a relatively low temperature. In addition, since a high mechanical strength can be obtained after fusion, the thermoplastic resin and the thermoplastic film cannot be released from each other even if the modification of the image is tried. Thus, it is difficult to forge and modify the card.

Abstract: PURPOSE:To improve dynamic characteristics of flotation and mass-productivity by composing an air bearing rail of an inflow side part, an outflow side part, and a coupling part and making the overall width of the coupling part narrower than that of any other part. CONSTITUTION:The air bearing rail 3 form the outside border of a slider main body 1 linearly and has the inflow side part A, outflow side part B, and coupling part C.
