The composition contains components A, B, and C. A: an unsaturated monomer mixture, which includes 20 to 90% by weight of an unsaturated monomer including methylmethacrylate as a major component, and 10 to 80% by weight of an unsaturated monomer having at least two polymerizable double bonds in one molecule; B: a polymer of an unsaturated monomer including methylmethacrylate as a major component, which polymer includes 20 to 100% by weight of partially crosslinked polymer particles and 0 to 80% by weight of non-crosslinked polymer particles; and C: a polymerization initiator.

Abstract: A substrate 12 consists of a transparent plastic made from polylactic acid as a material, and an optical disc 10 provided with the substrate 12 is heated up to a heat deflection temperature. As a result, the substrate 12 is softened, and pits 22 formed on a signal recording surface 20 of the substrate 12 are erased. Thus, data recorded on the optical disc 10 is unreadable, and even if the disc 10 is discarded, the optical disc 10 is never read carelessly in accordance with the disposal of the optical disc.

Abstract: A display device includes a light guide plate. A light incident on the light guide plate from a linear light source is reflected by a reflecting surface of each of prisms and emitted from a lower surface of the light guide plate. The emitted light is irradiated onto a liquid crystal panel, reflected by a reflecting layer provided within the liquid crystal panel and advances toward a front direction of a screen. Herein, the light guide plate has on its lower surface as an emission surface a number of minute protrusions each having a shape of triangle in vertical cross-section in a manner that the protrusions cover with no space therebetween a whole effective area of the lower surface, and thereby to obtain an antireflection effect.

Abstract: A client terminal can obtain a spot-specifying code by accessing a server via the Internet. At first, when a user wants to obtain a spot-specifying code pertinent to a spot, the user appoints the spot on a map shown in a display of the client terminal. When the user appoints the several spots on the map, marks and numerals that indicate the appointed spots are displayed. Upon finishing appointment of all the spots, the user clicks a button of ‘ISUUE SPOT-SPECIFYING CODE.’ The server then converts coordinates of the appointed spots into the spot-specifying codes using a conversion table to make a file. The file is thereby downloaded to the terminal.
