Title: Preventing method for meandering of metal strip
Inventor: MIZUTA SHIGEO
IPC: B21B39/00
Filed: 1985-11-30
Abstract: PURPOSE:To easily prevent the occurrence of meandering, by a method wherein, in the central line of a passage for a continuously running metal strip, an eddy current is generated to the metal strip by extending through a given magnetic flux in the direction of the thickness of a plate, and braking is applied by means of the eddy current and the magnetic flux. CONSTITUTION:A metal strip 1 is caused to run in the direction of an arrow mark 5 along a central line 3 of the metal strip 1. A coil 2 is so set that a magnetic axis 4, connecting centers of N and S of the coil 2, crosses the central line 3 at right angles, and a magnetic flux is exerted through in the direction of the thickness of a plate. When the metal strip 1 is displaced in the direction of, for example, an arrow mark 14, the magnetic axis 4 extends through a running line central line 13 of the metal strip 1, an eddy current is generated around the magnetic axis to the metal strip 1, and an electromagnetic force 10 is generated in the direction of the thickness of a plate by a Fleming's let hand rule by means of the eddy current and the magnetic flux. Moment 15 is generated by means of the electromagnetic force 10 and the driving force in a direction 5 of the metal strip 1 to correct meandering 14 of the metal strip 1. This constitution enables easy and automatic prevention of meandering of the metal strip 1.

Title: Stepping motor and instrument using the same
Inventor: FUKUMAN ATSUSHI
IPC: H02K37/12
Filed: 1997-10-06
Abstract: PROBLEM TO BE SOLVED: To make it possible to obtain a desired step angle without placing any speed reducing mechanism in-between, by placing a stator inside and a rotor outside, and rotating the rotor around the stator. SOLUTION: In a HB-type stepping motor 1, a pulse-like driving current is sequentially passed through an exiting coils 7 of a pair of pole teeth 5a extending so that the pair of pole teeth go away from each other. Accordingly, the small teeth 5b at the tips of the pole teeth 5a of a stator 5 are magnetized, and the teeth 8a of a rotor 8 are attracted to cause the rotor 8 to rotate stepwise. Since the stepping motor is of so-called outer rotor type, that is, the rotor 8 is rotated around the stator 5 positioned at the center, the inside diameter of the rotor 8 and the outside diameter of the stator 5 can be increased, and thus the motor can be designed so that the number of the teeth of the rotor 8 and the number of the teeth of the stator 5 are large, as compared with conventional inner rotor type.  As a result, the step angle of the stepping motor 1 can be reduced and equalized with step angles required for driving the pointers of instruments.
