Abstract: A data transfer device transfers a data signal being digital in synchronization with a clock signal and includes a delay section, a measurement section, and a control section. The delay section controls a delay amount given to the data signal. The measurement section acquires an acquisition timing of the data signal output from the delay section using test data transmitted at least once prior to data communication and the clock signal. The control section determines the delay amount for the data signal during a period of data communication based on the acquisition timing or a stored timing.

Abstract: The present invention relates to a monclonal antibody capable of suppressing the motility of cancer cells, a polypeptide recognizable by said anti-cancer antibody and its fragment peptides which is capable of suppressing the motility of cancer cells. The present invention also relates to a production and a use for preventing the matastasis of cancer thereof.

Abstract: A magnetic storage disc 1 has a plurality of concentric data tracks, with circumferentially staggered servo centering signals B, C recorded flanking each track in a sector shaped region of the disc. A rotationally driven spindle 2 positionally clamps the disc such that an index mark on the spindle base is sensed by a pickup 5 immediately following the servo sector. The pickup signal is reliably supplied to a host computer via a timer 16, a microprocessor 12 and a R/W interface 15 to enable read/write operations on an accessed track. A delayed output from the timer, at the end of the data portion of the track and at the beginning of the servo sector, terminates such operations, enables the R/W head 3 to be stepped to a next addressed track by an actuator 4 with coarse positioning, and initiates the accurate centering of the head by an open loop servo.
