Filed: 1986-03-31
Abstract: PURPOSE:To reduce the temperature coefficient of a hysteresis voltage by inserting respectively a resistor of emitters of transistors (TR) of differential pair and adding a new TR to a current mirror circuit so as to widen the setting of the hysteresis voltage. CONSTITUTION:Resistors Rl,R2 are inserted respectively to emitters of TRs Q1,Q2 constituting the differential pair. A constant current source 7 is connected to the connecting point between the resistors Rl and R2. TRs Q15,Q18 are added newly to current mirror circuits 14,15 respectively. When an input voltage is a prescribed value or over, the TR Q2 is turned off and the 1st stable state is attained. When the input voltage goes low, the collector current of the TR Q1 is zero, power is applied only to the circuit 15 to form the 2nd stable state. Thus, the setting of the hysteresis voltage is widened and the temperature coefficient of the hysteresis voltage is decreased.

Abstract: PURPOSE:To reduce the loss resulting from a leakage flux, by accommodating a winding inside a tank, filling the tank with insulating oil, and providing a tank magnetic shield on a tank wall closer to the winding and a clamp magnetic shield on the clamp of a core on a tank wall remote from the winding. CONSTITUTION:By virtue of the fact that tank walls 11b, 11c closer to windings 13 are also provided with respective tank magnetic shields 17b, 17c, there is no possibility of an abnormal temperature-rise of the tank walls 11b, 11c, clamps 23, 24 and clamp arm parts 26 on both sides of a clamp 21 due to the leakage flux from the windings 13 on both sides. Since a clamp 22 on the side of a tank wall 11e which is remote from the windings 13 has clamp magnetic shields 30 respectively provided on clamp arm parts 26-2, 26-3, 26-4 and 26-5, any leakage flux from the windins 13 is absorbed by the clamp magnetic shields 30 and turned to a core 12. Accordingly, it is possible to reduce the loss due to the heat generated particularly in clamp plate parts 25 of the clamp 21 and the clamp arm parts 26-2, 26-3, 26-4 and 26-5, and there is therefore no possibility for the overheating to occur.
