| 20100020007 | DISPLAY DEVICE, DISPLAY METHOD, AND ELECTRONIC DEVICE - There is provided a display device, including a display panel; a first light emitting unit for inputting a first input light to the display panel based on a first light emitting signal; a second light emitting unit for inputting second input light to the display panel based on a second light emitting signal; and light emitting control unit for outputting the first light emitting signal, the second light emitting signal, the image signal corresponding to the first input light, and the image signal corresponding to the second input light; where the light emitting control unit performs output of the first light emitting signal and the image signal of the color corresponding to the first input light in synchronization in a first sub-frame, and performs output of the second light emitting signal and the image signal of the color corresponding to the second input light in synchronization in a second sub-frame. | 01-28-2010 |
| 20100302477 | OPTICAL ELEMENT, ILLUMINATION DEVICE AND DISPLAY DEVICE - An optical element for an illumination device, an illumination device, and a display device using the illumination device is capable of performing surface light emission by utilizing a plurality of light guide members, and suppressing generation of color unevenness. | 12-02-2010 |
| 20110038178 | PLANAR ILLUMINATION DEVICE - A planar illumination device includes: a light guide plate formed by arranging a plurality of unit light guide plates each having a light emission surface as a front surface and a reflection surface as a back surface so that facing end surfaces of adjacent unit light guide plates of the plurality of unit light guide plates are closely arranged; and one or two or more light sources arranged on a side surface, in a direction where the plurality of unit light guide plates are arranged, of each of the plurality of unit light guide plates, in which a projection section is arranged on one of facing surfaces of two adjacent unit light guide plates in the arrangement direction and a recession section in which the projection section is engaged is arranged on the other of the facing surfaces of the two adjacent unit light guide plates. | 02-17-2011 |
| 20110109533 | SURFACE LIGHT SOURCE DEVICE AND DISPLAY - There is provided a surface light source device having a configuration where light sources are arranged on both of a pair of side surfaces of a light guide plate and allowed to independently form nonuniform light emission intensity distributions in which light emission intensity is lower and higher at places closer to and farther from each of the light sources. Light guide control sections controlling guiding of light from light sources are arranged on a reflection surface of a light guide plate. The light guide control section is configured of concave sections, and the concave sections include inclined surfaces facing the light source and inclined surfaces facing the light source, respectively, and the heights of the concave sections increase with increasing distance from the light source. A nonuniform light emission intensity distribution in which light emission intensity is lower and higher at places closer to and farther from the light source is formed by lighting of the light source. As the inclined angles of the inclined surfaces are larger than the inclined angles of the inclined surfaces, an influence of the light guide control section on light from the light source is reduced. | 05-12-2011 |
| 20110122652 | DISPLAY DEVICE AND OPTICAL DEVICE - Disclosed herein is a display device including, a visual target, and a backlight adapted to illuminate the visual target from the rear, the backlight including, a plurality of first light sources, second light sources, and a light guide plate, wherein the light guide plate has a plurality of projecting portions on a side surface portion thereof upon which the light, produced by the plurality of first and second light sources is incident, the projecting portions being arranged, along the side surface portion and project toward the one side of the given direction, the plurality of first light sources are disposed to be opposed to the tip surfaces of the plurality of projecting portions, and the second light sources are disposed to be opposed to the bottom surfaces of recessed portions formed between the plurality of projecting portions. | 05-26-2011 |

| 20080214390 | Catalyst For Purifying Exhaust Gas - The formation of H | 09-04-2008 |
| 20090082199 | Catalyst for Purifying Exhaust Gases - A catalyst for purifying exhaust gases includes a carrier substrate and a catalyst layer which is carried on the carrier substrate and contains a noble metal, a porous oxide and an addition oxide containing at least one selected from the group consisting of Ni, Bi, Sn, Fe, Co, Cu and Zn. Only a downstream section of the carrier substrate, which is located on a downstream side of an exhaust gas stream contains the addition oxide, whereas an upstream section of the carrier substrate does not contain the addition oxide. With this arrangement, in the upstream section of the carrier substrate, the noble metal and the addition oxide do not exist together so that the noble metal is not deteriorated with the addition oxide. As a result, in the upstream section, the purification performance as a three-way catalyst is favorably achieved, thereby restraining the emission of H | 03-26-2009 |
| 20090124494 | Catalyst For Purifying Exhaust Gases and Exhaust-Gas Purification Controller Using the Same - A catalyst for purifying exhaust gases includes a support substrate, and a catalytic loading layer. The support substrate has an exhaust-gas flow passage. The catalytic loading layer is formed on a surface of the exhaust-gas flow passage, and is composed of a porous oxide support and a catalytic ingredient. The catalytic loading layer includes an Rh area, and an oxidizing area. On the Rh area, rhodium is loaded as the catalytic ingredient. The oxidizing area is formed on an exhaust-gas flow downstream side with respect to the Rh area. On the oxidizing area, a catalytic ingredient exhibiting an oxidizing activity at least is loaded. Also disclosed is an exhaust-gas purification controller using the same. | 05-14-2009 |
| 20090163358 | Exhaust Gas Purifying Catalyst - In a three-way catalyst for purifying exhaust gases from internal combustion engines, scattering of bismuth components can be suppressed by employing a Bi—Ti composite oxide at a predetermined ratio. Accordingly, the effect of suppressing hydrogen sulfide emissions can be retained for a long time. This catalyst comprises a support substrate, and a catalyst layer formed on the support substrate and including a noble metal, a porous oxide, and a Bi—Ti composite oxide, and satisfies 0.3≦R≦1.5, where R is the molar ratio of the Bi content to the Ti content per unit volume of the support substrate. | 06-25-2009 |
