    摘要： In an idle state, servo information from all sectors is not used, but the servo information from every other sector or from every three or more sectors is used so that head positioning can be performed with only a minimum amount of servo information. The power to the electric circuitry of a write or read system and a servo system, which is not needed in the idle state, is interrupted, from the arrival of the selected servo information to the arrival of the next selected servo information, by a power control signal generated in accordance with the timing of the sectors. The power consumption can be reduced by the amount corresponding to turning off the circuitry not needed, plus the amount needed for computing for position control.

    摘要： A method and apparatus, in a direct access storage device including a head positioned for interaction with a data storage medium mounted on a rotating spindle, an actuator for positioning the head, and a servo control loop for positioning the actuator. The improvement comprises: a narrow band gain enhancing filter for connection in the servo control loop. The filter has a response frequency related to the rotational frequency of the spindle. The filter has programmable initial states. Also provided is a switch for switching in the narrow band filter as the head approaches a target position on the data storage medium. Initial states of the filter are determined and supplied to program the filter. At least one additional filter having a peak response frequency at a harmonic of the frequency of rotation of the spindle, may be provided. Initial states of the additional filters are determined and supplied to program the additional filter. The filter may include successive delay circuits for inputs to the filter, which circuits provide delayed outputs; multipliers for multiplying selected delayed outputs by a constant; and a summer for summing the delay outputs after the delayed outputs are multiplied by the multipliers. The initial states may be stored as phase, frequency and amplitude of a sine function.

    摘要： A disk drive with reduced seek acoustic noise and a method for implementation, without any additional hardware or mechanical modifications to the actuator includes a filter such that servo-loop stability is unaffected. The filter is inserted outside the existing servo loop to reshape the existing velocity profile in real time and to facilitate the suppression of forcing components that produce seek acoustics. A weighting factor may be used to provide a weighted average of the filtered and unfiltered velocity reference signal to the servo loop so that at the end of a track seek operation, the unfiltered reference signal is applied to the velocity servo, and there is almost no change in settle-out performance when the target track is reached. It is not necessary to store large volumes of velocity profile data to deal with different seek lengths.

    摘要： To obtain a fuel filler structure for a fuel tank wherein when causing an opening and closing valve to close, it can be ensured that the opening and closing valve does not rapidly rotate to a closed position in which it closes a fuel fill inlet, and when causing the opening and closing valve to open, the opening and closing valve can be opened with a small force. A fuel filler structure is equipped with a damper on the near side of a flapper valve in the insertion direction of a fuel nozzle. When the flapper valve rotates to an open position, the damper does not act on the flapper valve, and when the flapper valve rotates to a closed position, the damper acts on the flapper valve.
