    Abstract: A magnetic data embedding system (or disk servo writer) includes a stack with a master disk (3) and a plurality of magnetic disks (4) mounted on a shaft of a spindle motor (6), and a rotary positioner (11) which integrally holds one or more read-only heads (71 to 74) for reading the master disk and a plurality of groups of servo heads (101 to 104) and which simultaneously turns both of the kinds of heads. The groups of servo heads have access to the top and bottom sides of the magnetic disks. The servo heads are made carry out writing to the same (top or bottom) side of each of the disks in parallel, within assigned track ranges for the respective servo heads. In order to make the servo heads on the same side of the disks carry out writing correctly in their assigned track ranges in several of the disclosed embodiments, an address correction data memory (23) supplies information about track position errors between the read-only heads and their associated servo heads to a servo head address deriving unit (24), which corrects track addresses of items of servo information read by the read-only heads and transmits the corrected track addresses to a servo pattern generator (9) to make the servo heads write the corrected address. This shortens the time needed for writing servo patterns to magnet disks with high density and high accuracy.

    Abstract: A first sample hold circuit or S/H, for holding an amplitude value at a predetermined phase of pipe vibration waveform, detected by both sensors and, a second S/H for re-holding the value at the predetermined phase, a comparator for comparing second S/H output with a set value, an differential amplifier for amplifying a difference value thus obtained, and an exciter circuit for increasing and decreasing the vibration amplitude of the pipe responsive to this amplified difference value are provided so as not to cause any change in exciting frequency characteristic, even when outside vibrations are added to the pipe. The present invention enables oscillation waveform to be less distorted and a more stable operation to be achieved even when responsibility, relative to outside vibrations, is increased.

    Abstract: The present invention provides a method of cutting a workpiece efficiently with high accuracy by utilizing tension adjusters to approximate tension in a wire in a wire saw to a predetermined target tension while effectively reducing only tension in a winder-side wire. The method comprises a forward-driven cutting step of cutting a workpiece while moving a wire forward, a first switching step of reversing a driving direction of the wire, a backward-driven cutting step of cutting the workpiece while moving the wire backward, and a second switching step of reversing a driving direction of the wire and returning to the forward-driven cutting step, the steps being repeated in this order. In both switching steps, only tension in a winder-side wire is reduced by tension manipulators. A reduction in target wire tension therefor is performed after completion of deceleration of the wire in each switching step.
