    Abstract: PROBLEM TO BE SOLVED: To provide a machine tool capable of surely preventing occurrence of phase shift between a hob and a workpiece when the tooth part of the workpiece is re-machined.SOLUTION: A machine tool 1 re-machines a workpiece after positioning drive motors 21 and 27, the hob H and the workpiece W by stopping the drive motors 21 and 27 in a state that the rotational positions of the drive motors 21 and 27, the hob H and the workpiece W are coincident with their respective zero positions. For this purpose, a drive control section 33 recognizes, based on the rotational-speed ratio of the drive motor 21 and the hob H and/or the rotational-speed ratio of the drive motor 27 to the workpiece W, and detection signals obtained from detection sensors 28 and 29 detecting that the rotational positions of the drive motors 21 and 27 are at their respective zero positions, detection signals when the rotational positions of the drive motors 21 and 27 and the rotational positions of the hob H and the workpiece W are coincident with their respective zero positions, and stops the drive motors 21 and 27 so that the rotational positions of the drive motors 21 and 27, the hob H and the workpiece W are coincident with their respective zero positions.

    Abstract: PROBLEM TO BE SOLVED: To provide an angle detector easy to be manufactured and assembled, and manufactured at a low cost. SOLUTION: A circumferential face of a ring of a rotor constituting a magnetic angle detector is worked into an irregular shape of a gear shape by gear work (a). A groove 1 is worked in the axial-directional central part (b). Protrusion parts in an axial-directional half part are cut out while remaining only one protrusion, to form the rotor 10 having integrally a one-rotation signal generation part 10b obtained by the protrusion in a only one portion in the whole circumference of the ring, and an angle signal generation part 10a having gear-shaped unevenness over the whole circumference (c). A process for attaching the rotor 10 onto a rotary shaft requires only one process thereby. Only one magnetoresistive element is required thereby to generate a one-rotation signal.
