    摘要： A disc is provided which includes a disc body of disc shape having a center hole. An information recording area is formed on one side surface of the disc body. The information recording area has information thereon read by reflection of laser light. The information recording area has an inner circumferential edge positioned adjacent to the center hole. The disc body has a radius ranging from 39 mm to 80 mm, the center hole has a radius ranging from 7.5 mm to 7.55 mm, and the inner circumferential edge of the information recording area being positioned to extend from a radius of 15 mm to 22 mm from the center of the disc body. A disc may be manufactured by variations of the following disc manufacturing method including the steps of: supporting a stamper on a first mold by a supporting means; defining a forming space by clamping the first mold to a second mold; defining a center hole of the disc by advancing a center hole defining member into a center part of the forming space; connecting a injection means into the forming space by opening a gate member of a resin injection member and filling the forming space with a resin through a communicating hole from the injection means; and cooling the resin in the forming space after shutting off connection between the injection means and the forming space by closing the gate member of the resin injection member.

    摘要： A light guide plate is provided including a first lens portion comprising a plurality of recessed or projected lenticular unit lenses formed of the same resin as that of the light guide plate on a light emission surface. The plurality of lenticular unit lenses in the first lens portion are triangular prism portions whose respective vertexes have an angle of 125.degree. to 165.degree. and are so arranged that their respective ridge lines are nearly parallel to each other. Such construction makes it possible to set the number of lenticular lens sheets used to one or to further eliminate the necessity of the lenticular lens sheets, so that the cost of parts and the fabrication cost of the light guide plate can be reduced. A second lens portion may be provided on a light reflective surface opposite to the light emission surface on which the first lens portion is disposed, the second lens portion including a plurality of recessed or projected lenticular unit lenses formed of the same resin as that of the light guide plate. Alternatively, a light guide plate is provided having a plurality of grooves with approximately equal groove widths formed on a surface opposite to a light emission surface, the grooves being arranged substantially parallel to each other and the spacing between the grooves narrowing as the distance from the light incident surface increases, with the spacing from the far end of one of the plurality of grooves proximate to the light incident surface to the near end of a groove adjacent thereto farther away from the light incident surface being 5 to 15 times the groove width.

    摘要： 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.

    摘要： The present invention provides a light guide plate and a surface light source using the light guide plate to improve the utilization efficiency of external light and light from an internal light source and to achieve thinner width of the light guide plate. In this invention, internal light emitted from an internal light source 3 is brought to the inside of the light guide plate 1 from an internal light collecting surface 16 in the light guide plate 1, and external light such as natural light is brought to the inside of the light guide plate 1 from an external light collecting portion 11. The light brought to the inside of the light guide plate reflects and is converged several times from a reflective plate 15 mounted to the outside of the light reflective surface 14 and three side end surfaces 12 and is emitted from the light emissive surface 13 of the light guide plate 1 to a diffusing plate 6. The light incident to the diffusing plate 6 is diffused uniformly within the desired angle range by the diffusing plate 6 and a lens sheet 7, and is emitted from the lens sheet 7 as synthesized light.

    摘要： A seatbelt apparatus is provided which can constrain a passenger by ensuring removal of a slack of a lap belt when two pretensioners are activated under two different time frames. A pretensioner of a seatbelt retractor is activated first, and a shoulder belt and a lap belt are pulled in a direction toward the seatbelt retractor. Subsequently, a pretensioner of a belt anchor portion is activated and pulls a seatbelt toward the belt anchor portion, and hence a one-way tongue catches and locks the seatbelt. Accordingly, the shoulder belt is prevented from moving toward the lap belt through the tongue. Therefore, removal of the slack of the lap belt is ensured, and hence a lumber of the passenger is firmly fixed.

    摘要： The present invention was made to improve the strength, such as heat resistance, of a disc comprising a biodegradable resin. The optical disc according to the present invention is formed by bonding two substrates, at least one of the substrates having an information recording area. One substrate disposed on a light incident side of the optical disc is composed of a biodegradable resin that is uncrystallized and allows light to transmit therethrough. Another substrate disposed away from the light incident side of the optical disc is composed of the biodegradable resin having higher crystallinity than that of the substrate disposed on a light incident side of the optical disc.
