    摘要: A backlight 7 has light sources 2, a flat-plate-shaped light guide plate 3 for guiding the light emitted from the light sources 2 in a predetermined direction, a light shield louver 5, disposed so as to face the light guide plate 3, for shielding part of the light emerging from the light guide plate 3 according to angles of incidence, and a prism sheet 8 for converting the brightness distribution of the light incident on the light shield louver 5 into a predetermined brightness distribution. Owing to the prism sheet 8, the light incident on the light shield louver exhibits a brightness distribution such that brightness is at a minimum at an angle of incidence of 0°. Thus, the backlight 7, and a liquid crystal display device 1 employing it, permits light to emerge therefrom within a desired range of viewing angles while offering high brightness within that range, with reduced degradation of viewability.

    摘要: A lighting apparatus for irradiating a liquid crystal display panel from the back includes a light guiding plate having at least an end which is bent in a direction opposite to the liquid crystal display panel, and a light source disposed on the back surface of the light guiding plate with respect to the liquid crystal display panel. Light from the light source is incident on the bent section of the light guiding plate, reflected by a reflector covering the outside surface of the bent section, and then falls on a section corresponding to a data display space of the liquid crystal display panel. This structure enables an increase in the ratio of the area of a light emitting section to the area of the entire lighting apparatus.

    摘要: A controllable auto-heating type heat source is located at a periphery of a light source and light reflecting layers are placed between the light source and the controllable auto-heating type heat source. Therefore, use of a temperature detector and a control circuit in order to control the heat source are unnecessary, so that thermal runaway of the heat source is avoided. Further, the light reflecting layers reflect the light irradiated from the light source, so that the amount of the beam of light shielded by the heat source is decreased.

    摘要: A collision determination device includes a target cell designation unit that designates a target cell for a voxel model which represents the shape of a first object. A determination test point generation unit generates determination test points for the target cell. A spatial curve creation unit creates a spatial curve as the trajectory curve of a determination test point. A curve intersecting determination unit determines whether or not each boundary element of a boundary representation model representing the shape of a second object is intersecting the spatial curve. A distance computation unit computes the closest distance from the spatial curve to the boundary surface of the boundary representation model. A collision determination unit determines, based on the determination result and the computation result, whether there is a possibility of collision between both objects.
