  • Publication number: 20080033638
    Abstract: To safely and easily provide information that an operator needs, when a mobile body has started to move, a first acquiring unit and a second acquiring unit respectively acquire corresponding image information. Using the acquired image information and map information, an extracting unit extracts map information identical to the image information of the scenery around the mobile body. A selecting unit selects, from the extracted map information, an object that coincides with the position of the point viewed by the operator in the image information of the scenery around the mobile body. An output unit outputs information concerning the selected object.

  • Publication number: 20070271574
    Abstract: A carrying section of a disk apparatus includes a pair of arms disposed in a substantially symmetrical relationship with respect to the carrying direction of a disk in the proximity of the opposite ends of an opening formed in a housing such that the arms pivot around end portions thereof adjacent the opening in synchronism with each other in directions toward and away from each other, and a biasing element which biases the arms in a direction in which ends of the arms remote from the opening approach each other. The arms individually have rollers provided thereon which grip and carry the disk to a predetermined position. At least one of the rollers is rotated by the driving member to carry the disk. A controller includes a state decision section which decides a carrying state of the disk and a driving control section which stops, if it is decided that part of the disk is carried out to the outside of the housing, the driving of the driving means in a state wherein the rollers grip the disk.

  • Patent number: 6865077
    Abstract: A personal computer provided with heat-generating parts such as a CPU, a cooling unit that releases the heat generated by the heat-generating part to the outside of the personal computer has a container structure so that the cooling liquid in the interior does not leak to the outside. Also, part of the container structure is provided with a heat connection part for receiving the heat transferred from the outside of the cooling unit. Furthermore, there is provided means of heat transfer for transferring the heat generated by the heat-generating part to the cooling unit, one end of this means of heat transfer being thermally connected to the heat connection part of the cooling unit and the other end thereof being thermally connected to the heat-generating part. This prevents troubles in the personal computer due to the moisture permeation of the cooling liquid of cooling unit and leakage of the cooling liquid. Also, disassembly and assembly is made easy by forming the cooling unit as a separate structure.
