Abstract: A base fabric for an air bag is provided which is light-weight, flexible, superior in stowability, air shieldability, heat resistance and flame retardancy, further superior in the adhesion to resin and difficult to undergo stitch dislocation and fray. The air bag base fabric comprises a synthetic fiber fabric at least one surface of which is coated with resin. The resin is present also over at least 85% of the total area of an intertwined portion interface as a warp-weft crossing portion of the synthetic fiber fabric.

Abstract: A sheet-shaped lightguide member has a first surface (11A), which is divided into at least two areas. The sheet-shaped lightguide member has the first surface (11A) and a second surface (11B) that face each other and a peripheral edge surface (11C). The lightguide member receives light through at least a part of the peripheral edge surface, guides the light, and emits the guided light from the first surface (11A) serving as a light exit surface. The lightguide member is divided into the at least two light exit areas (14A, 14B) and has a light-blocking part (18) provided along a boundary between mutually adjacent light exit areas to block transmission of light between the adjacent light exit areas.

Abstract: A planar light-emitting device includes a lightguide plate (7), a light source including at least one light-emitting package (6) that makes light enter the lightguide plate, and a reflecting sheet (10, 11) that returns light leaking from the light source. The lightguide plate has an upper surface as a light exit surface, a lower surface opposite to the upper surface, and a peripheral edge surface a part of which is disposed as a light entrance surface (7?). The light source includes at least one light-emitting package (6) having a substrate, at least one light-emitting element mounted on a mount surface of the substrate, and a light-transmitting resin provided on the mount surface to seal the light-emitting element. The reflecting sheet is disposed to face at least one of the upper and lower surfaces of the lightguide plate and to extend beyond the light entrance surface as far as over or underneath the light-transmitting resin.

Abstract: A lighting device illuminates an operation panel having a plurality of display area groups (2A, 2B) each including at least one display area. The lighting device can illuminate the operation panel with different light for each display area group. The lighting device includes at least two sheet-shaped lightguide members (4A, 4B) corresponding to the plurality of display area groups, respectively. The lightguide members are stacked at a back of the operation panel. The lighting device further includes light sources (5A, 5B) that are disposed to face at least one edge of the respective sheet-shaped lightguide members each guiding light from the respective light sources. The lightguide members (4A, 4B) have respective light-emitting areas (8) that deflect and emit the guided light toward the display areas of the corresponding groups (2A, 2B).

Abstract: A backlight unit is capable of preventing an error in positioning of a light-emitting diode light source. The backlight unit (1) includes a film-shaped lightguide plate (6) having at least one light source accommodating hole (6a), and at least one light source (L) having at least one light-emitting diode element disposed in the light source accommodating hole. A retaining portion (6b) provided on the peripheral wall surface of the light source accommodating hole pressingly engages the peripheral wall surface of the light source to support it.

Abstract: A backlight unit provided between first and second parallel liquid crystal panels to illuminate both of them has a light source and a light guide plate that receives light from the light source and that emits light for illuminating the two liquid crystal panels. A shielding-reflecting sheet having an opening is disposed between the second liquid crystal panel and the light guide plate. The light from the light guide plate passes through the opening toward the second liquid crystal panel. The light reflectances of surfaces of the shielding-reflecting sheet and the second liquid crystal panel that face the light guide plate are set substantially equal. An annular frame surrounds the peripheral edge of the light guide plate. The frame has a first end surface on the first liquid crystal panel side thereof and a second end surface on the second liquid crystal panel side thereof.
