Filed: 1984-04-19
Abstract: PURPOSE:To prevent a winding of a motor from burning out due to a temperature rise owing to the repetition of starting operation by providing an over heat protecting circuit at starting time and an overheat protecting circuit at normal operation time. CONSTITUTION:When a starting pushbutton switch 32 is operated, an electromagnetic contactor 33 is operated to close a contact 33a, and an output from an inverter 5 is supplied to the winding 11 of a motor 1. When a yarn engagement is failed in the course of engaging the yarn so that a yarn strand is wound, a stop pushbutton switch 31 is operated to interrupt an electromagnetic contactor 33. When the strand wound on a roll is removed, a start pushbutton switch 32 is operated. When the starting operation is repeated during a short time to rise the temperature of the winding 11, the contact 2a of a temperature controller 2 opens, an auxiliary relay 35 operates to interrupt the circuit. On the other hand, when an abnormal current flows to the winding 11, an overheat protection sensor 12 operates to interrupt the circuit.

Title: Oscillation circuit
Inventor: ASAKAWA TATSUJI
IPC: H03L3/00
Filed: 1978-07-04
Abstract: PURPOSE: To obtain an oscillation circuit featuring a small amount of power consumption and low oscillation start voltage by using such circuit that features the effect equivalent to that obtained by increasing the resistance of the inverter comprising IGFET and the resistance.  
     CONSTITUTION: The power consumption is reduced since bias circuit C consisting of complementarily connected IGFET, main oscillation circuit A and output amplifier circuit B operate each near the threshold level. And the large amplified oscillation AC waveform is piled onto about 1/2 DC bias level of the power voltage and delivered to output out of circuit B. But output terminal out becomes the gate input of complementarily connected IGFET, and thus a perfect matching is secured for the logic level to the complimentary circuit. Furthermore, the current bias is constant for all circuits of C, A and B each since the output of circuit C is constant to the power voltage. As a result, the uniform oscillation characteristics can be obtained regardless of the level of the power voltage, thus obtaining an oscillation circuit featuring the low oscillation start voltage and reduced power consumption.
