  • Publication number: 20210086844
    Abstract: A vehicle includes a rear lamp, a side surface, and a rear surface. The rear lamp is disposed on a rear end and an upper end of a lower side surface and a rear end and a side end of the vehicle, and includes a lamp body extending in a front-rear direction of the vehicle. The side surface includes the lower side surface bulging toward a vehicle-width-direction outer side with respect to the rear lamp at a front side of a height position overlapping with the rear lamp. The rear surface includes an extending surface extending toward the vehicle-width-direction outer side with respect to the lamp body in a top view of the vehicle from a lower portion of the lamp body. A side surface airflow is directed toward a vehicle-width-direction inner side through the extending surface and the generation of a large trailing vortex is suppressed.

  • Publication number: 20080180830
    Abstract: An emergency unload verification device verifies whether or not a control unit to control an emergency unload operation in a storage apparatus is abnormal. A storage section stores previous waveform information of a control signal to be sent out by the control unit for controlling the emergency unload operation. A waveform comparing section compares a waveform information of a control signal, sent out by the control unit for controlling the emergency unload operation when the emergency unload operation is executed, with the waveform information stored into the storage section. An abnormality determining section determines whether or not the control circuit is abnormal on the basis of the comparison result of the waveform comparing section.

  • Publication number: 20070280077
    Abstract: In order to decrease alternate processing when a verification error is detected for an optical storage medium, a position BS and a length BL of a defect are stored when a verification error is detected, and based on this stored information, rewriting is performed with increasing the write power for the defective section. Thereby even if an LD driver with simple configuration and low price, which is used for APC control for a digital feedback loop by firmware, is used, the emission power can be increased only for the defective section, and the reproducing waveform of the defective section can be increased, and the use of alternate sectors can be decreased when writing is retried.
