20080259620 | Light emitting apparatus - A light guide unit which includes a front light emitting surface, a rear surface to which a light reflecting treatment is applied and a side end face which constitutes a light introducing plane and which is formed solid of a light transmissive material as a whole is divided by a vertical slit which reaches the rear reflecting surface. | 10-23-2008 |
20080291685 | Vehicle-purpose lighting tool - A vehicle-purpose lighting tool is featured by comprising: a light-conducting member having a front light-emitting plane, a rear plane having a concave/convex shape, and a side edge plane; and a light source arranged at a position opposite to the side edge plane; in which within external light which is entered via the front light-emitting plane into the light-conducting member, a portion of the external light which is directly traveled to the side edge plane is totally reflected on a boundary plane of the side edge plane portion; a plurality of reflecting portions are formed on the rear plane and are coupled to each other via a coupling portion in such a direction that the reflecting portions are separated apart from the side edge plane side; and distances between the plurality of reflecting portions and the front light-emitting plane are changed in a discontinuous manner along the separating direction. | 11-27-2008 |
20080303338 | Wheel for vehicle - A wheel for vehicle includes a wheel body, a decorated member, and a visible space. The wheel body has a rim, a hub, and a plurality of spokes connecting the hub and the rim. The decorated member is made from resin, is disposed on a surface of at least one of the spokes, and is retained to the wheel body. The visible space is disposed between the decorated member and the one of the spokes at least, exhibits a height in an axial direction of the wheel body, and is visible from an axial outer side of the wheel body. | 12-11-2008 |
20090027911 | Vehicular lamp - The invention is constituted by a vehicular lamp characterized in a lens having a first light source, a second light source, a front light emitting face, a side end face to which the first light source is opposed, and a rear face, wherein the rear face includes a lens having pluralities of reflecting portions and transmitting portions consecutively aligned alternately in a direction of being remote from the side end face, and a reflecting face arranged on a rear side of the lens, light of the first light source is incident on the lens from the side end face of the lens, reflected by an interface of the reflecting portion, thereafter, radiated from the front light emitting face, and light of the second light source is reflected by the reflecting portion, thereafter, incident on the lens from the transmitting portion and radiated from the front light emitting face. | 01-29-2009 |
20090127920 | Vehicle Wheel - The degree of freedom in design is increased while maintaining strength by enabling a decorative member to be disposed without thinning a wheel main body. | 05-21-2009 |
20100133894 | Vehicle Wheel - The degree of freedom in design is increased while maintaining strength by enabling a decorative member to be disposed without thinning a wheel main body. | 06-03-2010 |

20120010794 | CONTROL APPARATUS FOR AUTOMATIC TRANSMISSION AND CONTROL METHOD THEREOF - In an operation of controlling an automatic transmission, an engagement pressure for each hydraulic servo in a normal operation is determined so that none of friction engagement elements slips at each shift speed in the normal operation, and so that in case of a failure in which the friction engagement element that is supposed to be disengaged in the normal operation is engaged, one of the friction engagement elements slips, and thus one of the shift speeds is established. In the control operation, upon detection of a failure state in which a gear ratio after a shift operation is a gear ratio of a shift speed different from a shift speed to be established, the slipping friction engagement element is disengaged, and the shift speed that is different from the shift speed to be established is temporarily retained. | 01-12-2012 |
