Abstract: A vehicle body rear structure in which a protruding structure is disposed further rearward of a camera device, so that water droplets dropping on the surface of the vehicle body roll and pass through the protruding structure and thus are prevented from adhering to the camera device. The vehicle body rear structure includes: a camera device disposed at the rear of a vehicle; an exterior member having a mounting surface on which the camera device is mounted and a tilted surface tilted from the mounting surface toward a rear upper part of the vehicle; and a protruding strip portion disposed at a position further rearward of the vehicle than the camera device and further forward of the vehicle than the tilted surface.

Abstract: A vehicle imaging apparatus is attached to a rear part of a vehicle and is directed to a vehicle rearward direction. The vehicle imaging apparatus includes: an imaging lens that faces a vehicle rearward direction; a casing that holds the imaging lens; and a flow adjustment protrusion. The flow adjustment protrusion protrudes to a vehicle downward direction from a lower position of the imaging lens of the casing.

Abstract: A camera image display apparatus including a display request output part outputting a display request of camera images, a power supply part supplying power to a display unit, and a power supply control unit controlling flow of electricity so as to supply activating power from the power supply part to the display unit at a first time point within a predetermined time from a completion of an engine starting, when the display request is output by the display request output part at the first time point, and to supply activating power from the power supply part to the display unit at a second time point after lapse of the predetermined time, when the display request is not output within the predetermined time from the completion of the engine starting.

Abstract: An optical disk drive capable of detecting occurrence of step-out or tooth jump in a mechanism for transferring an optical pickup. The optical pickup is transferred in a radial direction of the optical disk by means of a stepping motor. Upon receipt of a seeking operation command from a host machine, a control section drives the stepping motor by way of a controller, to thus cause the optical pickup to perform seek up to a target address. When logical contradiction has arisen in a stepper pointer showing the amount of rotation of the stepping motor, the control section determines that step-out or tooth jump has arisen. Moreover, even when a difference exists between an address indicated by the value of the stepper pointer and an actual address, step-out or tooth jump is determined to have arisen. When the step-out or tooth jump has arisen in the transfer mechanism, the rotational speed of a spindle motor or the rotational speed of the stepping motor is decreased.

Abstract: An optical disk drive capable of detecting occurrence of tooth jump in a mechanism for transferring an optical pickup. The optical pickup is transferred in a radial direction of an optical disk by means of a stepping motor. A control section having received a seek operation command from a host machine drives the stepping motor by way of a controller, to thus cause the optical pickup to perform seek up to a target address. The amount of displacement between a current address achieved after seek operation and a target address is computed. When the amount of displacement is equal to or greater than a pitch P of the transfer mechanism; namely, the pitch P of a lead screw, the tooth jump is determined to have arisen. Seek conditions are changed, and seek is reperformed.
