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： 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： 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： 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.

摘要： In a beam irradiation device of the present invention, laser beams emitted from a semiconductor laser impinge on an irradiation lens supported by a lens actuator. The laser beams that have passed through the irradiation lens change in outgoing angle in the direction of a y-z plane as the lens actuator is driven. A laser beam scan in the target region is thus performed. A part of the laser beams that have passed through the irradiation lens is reflected and separated by a beam splitter. The separated beams are converged on a PSD through a converging lens. A DSP control circuit monitors a scan position of the laser beams that have passed through the irradiation lens based on a signal from the PSD. When an irradiation position has deviated from a scan trajectory, the DSP control circuit controls an actuator driving circuit to draw the irradiation position back onto the scan trajectory. This beam irradiation device can realize a smooth and stable beam scan operation with a simple construction.
