  • Patent number: 8380348
    Abstract: Provided is a robot capable of appropriately adjusting a position and the like of a main body in view of executing a specified task involving an interaction with a target object. While the position and posture of the main body (10) are being controlled according to a second target path, the robot (1) moves from a first specified area to a second specified area and stands there. In this state, a second position deviation (=the deviation of the position of the main body from a second target path) and a second posture deviation (=the deviation of the posture of the main body from a second target posture) are determined. According to the determination result, the second target path is corrected so that the subsequent position deviation and the like may be smaller.

  • Patent number: 8355224
    Abstract: Embodiments of the present invention help to prevent a head characteristic from being deteriorated by re-deposition or damage which occurs when a sensor film is etched, a track width is narrowed, and the head characteristic is stabilized. According to one embodiment, when it is assumed that the thickness of the sensor film on an air bearing surface is T, and a distance between an end of a medium layer that is interposed between a free layer and a pinned layer which comprise the sensor film and an end of the sensor film lowest portion, a relationship of 1.2×T?X?2.5×T is satisfied, and the ends of a pair of magnetic films which are in contact with both sides in the track-width direction through an insulator do not exist in the track central portion from the free layer end.

  • Patent number: 8339753
    Abstract: A magnetic read head having a novel magnetic bias structure that provides improved magnetic biasing for improved free layer robustness and reduced Barkhausen noise. The bias structure includes hard magnetic layer formed over first and second under-layers. At least a portion of the first under-layer is formed as discrete islands of material, and the second under-layer is formed over the first under-layer. The first under-layer has a thickness of 0.25 to 0.75 nm. The novel seed layer structure causes hard magnetic layer to have a magnetic anisotropy that is substantially parallel with the free layer of the sensor stack even in regions adjacent to the sensor stack.

  • Patent number: 8098042
    Abstract: A charging system for a walking robot which charges a battery mounted on the walking robot by connecting a power supplying connector provided in a charging station to a power receiving connector in the walking robot, wherein the walking robot is capable of moving without significant restrictions during charging. The charging system includes a lock mechanism for locking the power supplying connector to the power receiving connector. A connector holder holds the power supplying connector detachably, an advancing/retracting mechanism advances and retracts the connector holder in the anteroposterior direction, and a lock operation mechanism performs a lock operation and an unlock operation of the lock mechanism via the connector holder. After an advance of the connector holder, the lock mechanism performs the lock operation to lock the power supplying connector to the power receiving connector. Thereafter, the connector holder is retracted out of the power supplying connector.
