摘要:
A falling-time measuring unit measures time for which a fall of a storage device is consecutively detected by a fall detecting sensor. A head-position detecting unit detects a position of the head on a storage medium at a time of starting measuring the time. A moving-time calculating unit calculates necessary time for moving the head from the detected position to a destination position. A first-threshold determining unit determines whether the measured time exceeds a threshold calculated by a threshold calculating unit. A head-movement processing unit moves the head to the destination position when it is determined that the measured time exceeds the first threshold.

A retraction control unit controls a retraction of a head of a storage device to a retraction position apart from a ramp by a predetermined distance. When the head is retracted from the retraction position to the ramp, a speed control unit controls a speed of the head to ascend the ramp to be constant by outputting a preset control signal.

A head retracting apparatus retracts a head on a storage medium upon detecting a fall. A counter-value calculating unit calculates a counter value that changes with an increase of a falling time and an increase of a non-falling time. A retraction determining unit determines whether to retract the head, based on the calculated counter value.

A movement controlling unit performs movement control of a head toward a target track on a magnetic disk medium driving a head actuator, and a position controlling unit performs position control of the head actuator in accordance with proportional integral calculations such that a deviation of a head position relative to a track center is eliminated when the moving head arrives at the target track. A gain retaining unit retains an integral gain of the proportional integral calculations in an increased state during a predetermined retention time from the start of the position control, and a gain switching unit switches the increased integral gain smoothly to the original integral gain when the retention time has elapsed.

A method, apparatus, and computer program product for transacting a product purchase by a user. The product purchase is processed by a purchase server that recorded a unique user identification and is connected to an information providing server and a client (connected to the user) via a network. The purchase server: receives (from the information providing server) purchase data including purchase identity information including a description of a product selected by the user for purchase; receives (from the client) redirect data comprising purchase identity information describing the selected product; sends (to the client) a request for the unique user identification; receives (from the client) identification data pertaining to the user; authenticates the received identification data pertaining to the user; and validates purchase identity information in the received redirect data. The purchase identity information in both the purchase data and the redirect data does not include the unique user identification.

Worm gear mechanism includes a driving worm, a torque delivering worm wheel meshing with the worm, and an auxiliary worm wheel superimposed on the torque delivering worm wheel. The auxiliary worm wheel has a pitch diameter greater than that of the torque delivering worm wheel. The auxiliary worm wheel is biased against the driving worm wheel via a biasing member in the form of a leaf spring.

There are disclosed a semiconductor integrated circuit device, a semiconductor integrated circuit wiring method and a cell arranging method, which can reduce delay in a semiconductor integrated circuit and improve noise resistibility, achieve facility of wiring design, and reduce production cost. The present invention forms an X-Y reference wiring grid using wirings of a total of M (M≧2) layers in which an n-th (n≧2) layer wiring intersects orthogonally with a (n−1)-th layer wiring, and forms an oblique wiring grid which intersects with the reference wiring layer to have an angle of 45 degree or 135 degree is formed by a (m+1)-th layer wiring and a (m+2)-th layer wiring which are intersected orthogonally with each other, such that the(m+1)-th layer wiring and(m+2)-th layer wiring in the oblique wiring grid has a wiring pitch of {square root over (2)} times of that of wiring in the reference wiring grid, and also wiring widths of {square root over (2)} times of that of wiring in the reference wiring layer.
摘要:
A data input/output control apparatus and a storage device accessing method are provided wherein multiple information is simultaneously supplied to multiple users. Multiple information to be supplied to users is stored distributedly in a plurality of storage devices. A slot allocating unit determines the number S of slots such that the value S is prime to the number D of storage devices, and groups time zones in which data is read from or written into the storage devices to S slots in access order. On receiving an access demand from a user, the slot allocating unit allocates slots to the user. When writing data into a specific storage device, an access control unit writes data into the specific storage device by using a specific slot for accessing the specific storage device, from among the slots allocated to the user, and a slot which is D-1 slots before the specific slot. Consequently, a plurality of groups (dependence rings) of mutually dependent slots are formed.
