  • Publication number: 20150224895
    Abstract: An electric driving wheel type work vehicle has a traveling motor 21, an inverter 313 for supplying the motor with three-phase power converted from DC power, a pre-driver circuit 312 for supplying a gate signal 316 to the inverter 313 on the basis of an input PWM signal, a controller 311 for outputting to the pre-driver circuit the PWM signal 315 for controlling the driving of the motor 21, parking brake means 10, and parking brake condition detection means 12 that detects the condition of the parking brake means 10. When the parking brake condition detection means 12 detects the parking brake means 10 has been operated, the pre-driver circuit 312 cuts off the output of the gate signal 316, or the input of the PWM to the pre-driver circuit 312 is cut off.

  • Patent number: 8742360
    Abstract: Plural camera heads are each placed in a position capable of detection of radiation emitted from a radiation source. Compton cones obtained from the detection data output from each of the plural camera heads are projected onto three-dimensional space and an image based on the radiation source is reconstructed. In addition, projected images from projecting Compton cones obtained from the detection data output from each camera head onto two-dimensional planes are also employed for determining a three-dimensional space excluding regions where the radiation source is not present. Reconstruction of images based on the radiation source is then performed within the determined three-dimensional space.

  • Publication number: 20110131115
    Abstract: A purchase type determining unit 244 determines whether content is rental content, which has a valid time limit for enjoying, from purchasing type information included in the license information. An icon image processing unit 352 disposes an icon image of the content in a menu screen. In case the content is determined to be rental content by the purchase type determining unit 244, a rental mark disposing unit 356 disposes a rental mark indicating that associated content is rental content near the icon image of the content or disposes the rental mark so as to overlap with the icon image of the content.

  • Publication number: 20060212404
    Abstract: A content reproduction apparatus and method is disclosed wherein the user can grasp complicated licenses or a relationship of licenses of a plurality of contents intuitively and with certainty from a time line representation. The content reproduction apparatus reproduces a content based on a license for permitting reproduction of the content and includes a content storage section configured to store contents and licenses. A reproduction schedule display section displays a reproduction schedule wherein, where any of the licenses includes a reproduction permission period for a corresponding one of the contents, the reproduction permission period for the content is represented as a time line. A content reproduction section reproduces the content only within the reproduction time period in response to a request from a user, and a content display section displays the reproduction schedule or the content.
