Patent JP-H04138055-A (JP)
Title: Single-phase synchronous motor
Inventor: MIYAZAWA HIROSHI
IPC: H02K21/14
Filed: 1990-09-27
Abstract: PURPOSE:To obtain a cheap single-phase synchronous motor, which can be started always by an initial signal despite single constitution, by providing a rotor multiple-magnetized, stator having an equal number of pole teeth in a circumferential direction opposed to poles of a rotor magnet and permanent magnets for giving a bias field to the specific pole tooth. CONSTITUTION:A magnetic circuit is constituted by arranging pole teeth 5 of a stator alternately built in opposed to poles of a rotor magnet 1 multiple- magnetized in a cylindrical permanent magnet. Since the pole teeth are formed to serve as an N or S-pole by permanent magnets 7 for giving a bias field, repulsion and attraction are performed in accordance with the pole of the rotor magnet to place a stable point of rotor rotation in a position where the pole teeth 5 and the pole of the rotor magnet are determined. When a coil is excited, force acts in one direction. When the coil is started excited, a direction of flowing a current in the coil is determined to always first excite the pole teeth, opposed to the rotor magnet N pole, to an N pole and reversely the pole teeth, opposed to the rotor magnet S pole, to an S pole, so that self starting is made possible without a mistake.

Patent JP-H04135203-A (JP)
Title: Grid shift system
Inventor: ISOBE SHINICHI
IPC: G05B19/18
Filed: 1990-09-27
Abstract: PURPOSE:To easily change a reference point beyond an inter-grid distance by neglecting the grid signals equivalent to the quotient of the division among those detected grid signals, and stopping a machine movable part at the reference point set on the basis of the shifted grid point. CONSTITUTION:A programmable machine controller RMC 15 reads a deceleration signal *DECX out of an input/output circuit 23. Thus a limit switch 3 is detouched from a dog 2 and the reference point return processing is carried on until the switch 3 reaches the grid position set right after the switch 3 is turned off. A processor 11 divides the shift extent obtained right after the switch 3 is restored by the inter-grid signal distance produced in proportion to the shift extent of a machine table 1. Based on the quotient of this division, a position control circuit 18 neglects the grid signals equivalent to the division quotient. Therefore the table 1 returns to the reference point based on the positions of grids in number equal to (quotient + 1). In such a way, the reference point is easily changed.
