  • Publication number: 20110156424
    Abstract: A pick-up style utility vehicle according to the present invention has a front seat, a rear seat, a cargo bed, a cabin frame surrounding a riding space, and a screen shield partitioning the cargo bed and a rear riding space in front of the cargo bed. The cargo bed can be changed between an expanded state in which the cargo bed is expanded in a front direction to the rear riding space and a non-expanded state not occupying the rear riding space. A backrest for the rear seat is attached to the screen shield. The screen shield can be shifted between a position in the expanded state and a position in the non-expanded state when a seat bottom and the backrest of the rear seat are changed between a retracted state in which the seat bottom and the backrest are erected on the same straight line and a seatable used state.

  • Patent number: 7913281
    Abstract: This digital broadcast recording device includes a tuner unit, a channel table recording unit, an image output unit, an OSD generation unit, an actuation unit, and a channel presetting unit. The channel table recording unit records a channel table. An auto presetting unit sets virtual channels. If the number of a virtual channel is duplicated upon several physical channels, the channel presetting unit commands the OSD generation unit to display an OSD to the effect that this number is duplicated. And, when the actuation unit has received a predetermined actuation input, the channel presetting unit searches for a vacant channel.
