摘要： An eccentric-shape machining apparatus as well as an eccentric-shape machining method are provided which can efficiently and accurately bore, contour or thread a workpiece about any position other than the rotational center of the workpiece. The workpiece is rotatably driven while controlling the rotational phase of the workpiece. A rotating tool spindle adapted to mount a cutting tool is rotatably driven while controlling the rotational phase of the rotating tool spindle. The rotating tool spindle is mounted on a cutting head which is controllably fed and positioned in Z-axis extending parallel to X-axis perpendicular to the axis of the rotating tool spindle. During one complete revolution of the workpiece, the rotational phases of the main spindle and rotating tool spindle and the movement of the cutting head in the X-axis direction are simultaneously controlled such that the cutting tool is brought into contact with the inner and outer peripheries of the workpiece by a given depth of cut. At the same time, the movement of the cutting head in the Z-axis direction is controlled. As well as the work rotation mode described above, the work oscillation mode can be carried out.

摘要： To prevent adverse effect, on machining accuracy, of cogging thrust of linear motors when used in a combined linear motor driving a machine tool. Three linear motor movers are fixedly attached to a moving table of a machine tool, while three linear motor stators are fixedly attached to a base. The three linear motors are driven in parallel to thereby drive the moving table. The respective linear motor stators are fixed to the base so as to have fixed phases relative to the base, stepwisely displaced by an electrical angle 60° whereby cogging thrust is leveled in the entire combined linear motor.

摘要： A magnetic or optical disk apparatus having a flexible disk rotated at high speed and head sliders for reading and writing information on the disk, floating from both sides of the disk. The disk apparatus is also provided with straightening plates for keeping air flow in the radial direction of the disk as a laminar flow to surely prevent the disk from being vibrated at the time when the disk is rotated at high speed. As the result, positions of the head sliders relative to the disk can be surely and accurately maintained to provide heads with excellent recording and reproducing characteristics. Mass storage and high speed access can be thus achieved without damaging the flexible disk and the disk apparatus can be smaller-sized with lighter weight and lower cost.

摘要： A disk drive is provided which uses a disk having a maximal limit cylinder group formed based on an initially recorded servo data before being assembled in a drive body. A CPU sets an actually usable data recording area on the disk by seeking the head in a radial direction over the disk. Further, the CPU allows the generation of a translation table for obtaining a correspondence between inherent physical cylinder address information of an effective cylinder group contained in the set data recording area and logical cylinder address information set to identify the effective cylinder group and allows the translation table to be stored in a memory. The CPU refers to the translation table when, in response to an access request from a host system, control is made to position a head to a target position, and finds-physical cylinder address information corresponding to the target cylinder.
