  • Patent number: 10358794
    Abstract: A work vehicle, includes: a lift arm rotatably linked to a front portion of a vehicle body of a work vehicle so as to be allowed to swing along an up/down direction; an operation lever that can be operated within a range between a raising operation end position and a lowering operation end position, and is operated to raise and lower the lift arm; an up detent mechanism having a holding function for holding the operation lever at the raising operation end position once the operation lever is operated to the raising operation end position; and a down detent mechanism having a holding function for holding the operation lever at the lowering operation end position once the operation lever is operated to the lowering operation end position, wherein: when an angle of the lift arm becomes greater than a predetermined upper limit, the holding function of the up detent mechanism and the holding function of the down detent mechanism are disengaged.

  • Patent number: 7177528
    Abstract: A disk drive apparatus is provided which is capable of performing recording and playback processing of an AV data stream requiring real-time characteristics and processing in an operation mode suitable for battery driving. The construction is formed in such a way that a first operation mode in which a disk rotation speed is set to be low, to which error handling in which an upper limit of an error handling time is determined as an error processing method suitable for performing recording or playback of real-time continuous information is made to correspond, and a second operation mode in which the disk rotation speed is set to be high and in which retries can be performed repeatedly as an error processing method suitable for performing recording or playback of data having high reliability, can be set. Thus, lower power consumption of real-time continuous data processing in image recording and playback by battery driving, such as in a portable video camera, is realized.

  • Patent number: 6999389
    Abstract: A disk recording/reproduction device ideal for processing audio-visual data streams requiring real-time characteristics. A disk device has an operating mode ideal for recording and reproduction of motion image and audio data requiring real-time continuity by limiting the time needed for error processing, and the host incorporating the disk device can easily monitor the real-time continuity. The host can specify the urgency of individual recording and reproduction instructions to the disk so that control of real-time continuity can be actively implemented in better detail. A means for assigning a total number to a plurality of simultaneously recorded or reproduced data streams as well assigning individual data stream numbers allows informing the disk device of the throughput required by the host.

  • Patent number: 6754155
    Abstract: An information recording medium and information processing device are provided so that recording medium-identifying ID information cannot be rewritten. Unique ID information specific to a recording medium is recorded in a servo zone, which is not a data zone in which data recording/reproduction can be performed. After the medium is installed in the disk drive, a user cannot rewrite the recorded ID information and can only read it. When information distributed via a network is stored in a storage device, the ID in the servo zone is verified so that the information can be stored in the storage device only when the storage device is properly licensed.
