  • Publication number: 20150062135
    Abstract: According to one embodiment, a display apparatus includes a receiver, a display controller, a camera, a processor, and a generator. The receiver receives data corresponding to a plurality of images. The display controller displays different images to a plurality of viewpoints, respectively. The processor assigns a number of viewpoints to each of the plurality of display images based on an image captured by the camera. The generator generates a signal for displaying the plurality of images according to the number of viewpoints assigned to each of the images.

  • Patent number: 8932172
    Abstract: A differential includes a pinion shaft holder, a differential case, a first side gear, a second side gear, a first spring and a second spring. The differential case includes a first side boss portion and a second side boss portion. The first spring is interposed between the first side boss portion and the first side gear. The second spring is interposed between the second side boss portion and the second side gear. A recessed portion is provided on the pinion shaft holder and is configured to avoid interference with an auxiliary tool. The auxiliary tool maintains one of the first spring and the second spring in the compressed state.

  • Patent number: 8508090
    Abstract: PROBLEM TO BE SOLVED: A lubrication structure of a power transmission apparatus is provided with a lubricating liquid transport pipe for cooling a rotating electrical machine used to allow a lubricated member positioned axially outwardly of the rotating electrical machine to be lubricated in the axial direction. SOLUTION: A lubrication structure comprises an oil pipe 44 having discharge nozzles 44a, 44c positioned vertically above coil ends 20a, 20b and discharge nozzles 44d, 44e axially outwardly of the discharge nozzle 44c in juxtaposed relationship with each other at the other axial end portion of the oil pipe 44, and a guide member 22 radially extending between the discharge nozzles 44d, 44e in the axial direction of a motor M and having a radially inner peripheral portion covering bearings 24, 42. The guide member 22 has a guide rib extending axially outwardly of a flange portion 22a to guide the oil discharged from the discharge nozzle 44e in the axial direction.

  • Patent number: 8348800
    Abstract: A vehicle power transmission device includes: an input shaft; a planetary gear type speed reducer disposed concentrically to the input shaft to reduce and output rotation input to the input shaft; and a differential gear device disposed adjacently to the input shaft in a shaft center direction, the differential gear device being rotationally driven by the speed reducer to transmit a drive force to a pair of axles disposed on the shaft center while allowing a rotational difference between the axles, the speed reducer including a sun gear that is fit with a shaft end portion of the input shaft in a relatively non-rotatable manner, the sun gear being prevented from relatively moving toward the differential gear device by an annular snap ring fit and attached to an annular snap ring groove formed on an outer circumferential surface of the shaft end portion of the input shaft on the differential gear device side of the sun gear, the differential gear device including a differential case having a cylindrical end po

  • Patent number: 7818119
    Abstract: According to one embodiment, an electronic apparatus comprises a storage module, a location measuring module, a communication module, and a navigation image generating module. The storage module stores image data corresponding to respective symbols, and data of simplified diagram templates in each of which positions are set on an image showing a shape of a road, symbols being placed at the respective positions. The location measuring module measures a current location. The communication module transmits the current location to an external communication apparatus and receives navigation information on a navigation point corresponding to the current location, the navigation information including a simplified diagram template identification number, symbol identification numbers, and position specification numbers.
