IPC: H02P9/08
Filed: 1985-09-12
Abstract: PURPOSE:To prevent an output voltage of a generator at voltage rising time such as an operation starting initial time from overshooting by starting a voltage regulating operation in the rising portion of the output voltage of the generator. CONSTITUTION:When the output voltage of a generator G rises, the reference voltage VZ1 of the prescribed voltage level specified by a Zener voltage is formed at a connecting point A at relatively early time after rising the output voltage V0. As a capacitor Cs is charged, the DC voltage level of a connecting point C gradually falls from the level of the voltage VZ1 and becomes substantially stable when the charge of the capacitor Cs is completed. The pulsating voltage level of the detected voltage Vc divided by a voltage divider 7 from the voltage of the point B rises or falls the Zener voltage level of a Zener diode ZD to regulate the voltage.

Abstract: PROBLEM TO BE SOLVED: To improve the responsiveness and the detection sensibility with respect to the tension variation by definitely regulating the tension based on the rotation torque with a tension regulating means of a wire installed between a winding means of the wire and an un-winding means. SOLUTION: When winding a yarn solder 2 is instructed from an operation table, an un-winding motor 3 is controlled so as to synchronize to the rotation of a spindle motor 7, the transferable tension variation applied on the yarn solder 2 in the beginning time of winding is restricted largely and the yarn solder 2 is prevented from loosing. When the winding of yarn solder 2 is started, the tension of the yarn solder 2 hung around an arm 4a is changed, the arm 4a is displaced in the arrow mark X2 direction, the displacing amount is outputted to a winding controller. The driving current of the unwinding motor 3 is controlled so that the displacement of the arm 4a is returned to the origin and the tension of the yarn solder 2 is kept definitely. Therefore, the responsiveness to the tension variation is improved and winding is executed without giving the stress on the wire.
