Title: Step motor and rotating method for rotator
Inventor: HIRABAYASHI HIROYUKI
IPC: H02K37/04
Filed: 1992-10-09
Abstract: PURPOSE:To allow alignment of patterns with no positional shift in a step motor by specifying the number of rotor teeth, exciting the winding with single- phase or two-phase, and specifying the step angle and the number of steps of rotor. CONSTITUTION:A yoke 2 is provided with a four-phase winding 7 while a rotor 6 is provided with a rotator 11 and 21 pieces of patterns 12 are formed on the peripheral face 11a of the rotator 11. Interval (n) between the centers 12a of pattern is set constant. In case of four-phase winding, number of rotor teeth is set at 63 and the number of steps per single revolution is set integer times as large as the number 21 of the patterns 12. Assuming (n) is an integer, step angle 9 is determined by the number of phases of motor winding 7 according to a formula; 21Xn=360 deg./theta. In case of a four-phase step motor having number of rotor teeth equal to 63, single-phase excitation or two-phase excitation is employed over the entire periphery and a step angle theta=1.429 deg. is obtained for two steps according to a formula 21Xn=25. Consequently, conventional shift of one step angle is eliminated and the center of pattern can be matched perfectly.

Title: Controller of electric railcar
Inventor: UJIIE AKIHIKO
IPC: B60L3/00
Filed: 1984-12-24
Abstract: PURPOSE:To prevent a motor from flowing an overcurrent by setting a chopper conduction rate to zero at disconnecting time, and gradually increasing a motor current from zero to the prescribed value with a delay time at reconnecting time. CONSTITUTION:When a pantograph is disconnected so that the voltage VC of a filter capacitor 4 arrives at the lower threshold value of a comparator 27, switches 22, 24 are switched to L side to set a current command value IC to 0, and a chopper conduction rate alpha also becomes 0. After a short time, the pantograph is reconnected, and when the voltage VC arrives at the upper threshold value of the comparator 27, the switches 22, 24 are switched to H side after the prescribed time limit from this time. Thus, the value IC rises from 0 to the primary delay represented by the primary delay circuit 23. thus, the overshoot of the filter capacitor voltage at reconnecting time can be suppressed.

Title: Yarn guide
Inventor: MIHARA JUN
IPC: B65H57/24
Filed: 1993-10-29
Abstract: PURPOSE:To concurrently satisfy the improvement of yarn quality and the reduction of friction resistance and perform the fiber manufacturing process at a high speed by forming a yarn guide section with a composite ceramic containing free carbon, and specifying the center line average roughness (Ra) of the surface. CONSTITUTION:This yarn guide 1 is formed into a pin shape, and the whole is made of a composite ceramic containing free carbon. The center line average roughness (Ra) of the surface 1a guiding the yarn of the yarn guide 1 is set to 0.4mum or below to form a smooth face. When a fiber 2 is guided on the surface 1a, such trouble that fuzzing occurs on the fiber 2 can be prevented because the surface 1a is a smooth face. Since the yarn guide 1 itself contains free carbon having a self-lubricating action, the friction resistance with the fiber 2 can be reduced, and a high yarn feeding speed can be coped with. A metal oxide or a metal carbide such as alumina, zirconia, silicon carbide, or the like is used for the composite ceramic containing free carbon.

Abstract: PURPOSE:To record information with an optimum power at all times and to improve CN ratio by irradiating over entire sector with laser beams with outgoing power larger than the outgoing power at the time of erasure in the case when an unused magneto-optical disk is mounted. CONSTITUTION:After forming a film in the process of manufacture, the driving conditions of a disk stabilizing processing are recorded in the bender unique area of a specific sector in the magneto-optical disk 11. When the unused disk 11 is mounted on a device, the record information of the bender unique area is read with rated driving conditions. Then, basing on the read driving conditions, the laser beam with the outgoing power larger than the one at the time of the normal erasure is radiated over the entire sectors and at the same time, magnetic field in a direction same as the data erasure time is impressed. Thus, a recording layer is heated up to a high temperature, the amorphous structure of the recording layer is fluctuated and is stabilized. At this time, the data of the respective sectors are erased. Thereafter, the driving conditions are returned to the rated conditions and a normal operation is performed.
