20100237725ROTATING ELECTRIC MACHINE AND DRIVE DEVICE - There is provided a rotating electric machine capable of preventing a coolant from being retained at an outer surface of a rotor. This rotating electric machine includes a rotation shaft provided so as to be rotatable, a core body secured to the rotation shaft, a permanent magnet embedded in the core body, and an end plate provided so as to be opposed to an axial end surface of the core body. A first coolant channel is formed in the rotation shaft to allow a coolant to flow therethrough. A second coolant channel is formed between the end plate and the axial end surface of the core body to communicate with the first coolant channel. A partition wall that partitions the second coolant channel in a circumferential direction and a path wall that guides the coolant in the second coolant channel toward an outer peripheral edge region of the axial end surface where the permanent magnet is placed are formed inside the second coolant channel.09-23-2010

20090158124DATA STORAGE APPARATUS AND DATA STORAGE METHOD - In the ordinary operation mode, a data storage apparatus writes data into a first flash memory, while writing ECC data, which is used for correcting the data written in the first flash memory, into a second flash memory. When there is no remaining storage space in the first flash memory, the data storage apparatus deletes existing ECC data previously written in the second flash memory and writes ordinary data into the second flash memory. This arrangement enhances the reliability of data and enables effective use of the original storage space in the system of data storage with multiple storage areas.06-18-2009
20090164538DATA STORAGE APPARATUS AND INITIALIZATION METHOD THEREOF - A data storage apparatus comprises a USB connector, a USB control circuit, a flash controller, and a flash memory. After the process of formatting the data storage apparatus by a host device, the flash controller forcibly rewrites FAT number data recorded in a bios parameter block area from ‘2’ to ‘1’ at the time of restoration of power supply. Such rewriting of the FAT number data causes the host device to identify the presence of only one FAT area. This arrangement desirably improves the data writing efficiency of the data storage apparatus configured to generate multiple management tables in the formatting process by the host device.06-25-2009

20080259620Light 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
20080291685Vehicle-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
20080303338Wheel 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
20090027911Vehicular 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
20090127920Vehicle 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
20100232174Front Grill - A vehicle front grill includes a grill main body and lamp housings that are integrally formed. A surface of the grill main body and surfaces of the lamp housings are coated with a single plating film, and light originating from the lamps accommodated in the lamp housings is reflected by the plating films of the lamp housings.09-16-2010
20100246205Vehicle headlamp - A vehicle head lamp comprising a first low beam member including a first light source part; a second low beam member including a second light source part, wherein the first low beam member and the second low beam member are arranged in a vertical direction and are both reflective type; a first frame including a partition, the first frame supporting the first low beam member and the second low beam member, and the partition separating the first low beam member and the second low beam member; and a storage provided in a rear side of the partition, the storage accommodating the first and the second light source parts.09-30-2010
