摘要： A control method for an optical disk drive is disclosed. In the control method, first and second light beams output from an optical head are irradiated to an optical disk. Information is recorded or reproduced using the first light beam, and information is deleted using the second light beam. The control method consists of steps described below. At a step, the moving velocity of the first light beam is calculated, and the moving velocity of the first light beam is controlled so that the moving velocity varies in conformity to a first velocity profile predetermined. Herein, the first velocity profile is pre-set to assist the first light beam in reaching a target track for the shortest time. At the next step, the position of the optical head is controlled so that the optical head follows the first light beam. At the next step, if the first light beam is accelerating or traveling at a constant velocity, the position of the second light beam is controlled so that the second light beam follows the optical head. At the next step, if the first light beam starts decelerating, data of a distance of the second light beam to the target track is updated using data of a distance of the first light beam to the target track. At the next step, if the first light beam is decelerating, the moving velocity of the second light beam is calculated. The moving velocity of the second light beam is controlled so that the moving velocity varies in conformity to a second velocity profile predetermined.

摘要： A digital servo circuit for an optical disk player having a tracking actuator utilizes a digital filter for alternately extracting from a tracking error signal a frequency component within a specified band and a high-frequency component. In response to the high-frequency component, a braking force is applied to the tracking actuator when a brake ON command is issued. Coefficient values in the digital filter are set up depending on whether the brake ON command is issued.

摘要： An optical disk player provided with a digital servo circuit uses a time-sharing multifunctional digital filter, in which a plurality of filter functions are realized with a single filter. By lowering the sampling frequency of the plurality of digital filter functions than the master clock of the signal processing circuit and operating the plurality of digital filters on a time-sharing basis, the number of steps of the signal processing command can be decreased and the circuit scale can be reduced. By constructing a High Pass Tracking Zero Cross HPF and an anti-shock BPF of a digital filter using the same step, reduction in the circuit scale and increase in the sampling rate can be attained.

摘要： When rolls in a rolling mill are repaired, a roll stand is first dismounted from the rolling mill. Then the dismounted roll stand is secured and the rolls are brought near to a housing of the roll stand in the axial direction of the roll. In this situation the rolls are cut. After the rolls have been cut, the roll stand is released from being secured. Then the roll stand is mounted on the rolling mill.A cutting apparatus used for cutting rolls comprises a base frame and a stand mounted on the base frame for placing the roll stand thereon. The housing of the roll stand placed on the stand is secured against the base frame. Furthermore, the rolls of the roll stand are brought near to the housing in the axial direction of the roll and are located. In the situation located against the housing, the rolls are rotated by a roll rotating apparatus and cut with a cutting tool.

摘要： In the fabrication of a plastic sleeve by heat sealing overlapped ends of a plastic film blank wrapped around a mandrel, a part of the underlying overlapped end is often melted inadvertently and adheres to the mandrel, obstructing easy stripping of the sleeve off the mandrel. Accordingly, a tensioning groove is formed in the mandrel surface, and a pressing-in bar is pressed thereinto over the sleeve while a part of the sleeve is held stationary against the mandrel by a holding plate to pull the sleeve part thus adhering sidewise in the peripheral direction of the mandrel and thereby to peel away and free the same.
