Filed: 1978-03-25
Abstract: PURPOSE:To prevent oscillation when an inductive load is OFF, by connecting Zener diodes between the collector and emitter of a drive-stage transistor simultaneously with the diffusion of the base and emitter of a transistor constituting a Darlington circuit. CONSTITUTION:On one surface of collector 10, drive-stage transistor Tr1 and output-stage transistor Tr2 are both formed.

Abstract: PURPOSE: To obtain a Josephson circuit wherein a superconductive closed circuit is formed by four or more Josephson junctions so that a predetermined function is achieved by making use of the characteristic that the fluxoid quantum is preserved without any inductance element.  
     CONSTITUTION: Four or more Josephson junctions J 1 , J 2 ...JN are connected successively to form a superconductive closed circuit M. The first current line 21 is derived from the neutral point A of connection between the junctions J 1  and J 2 . Similarly, a second and third current lines 22 and 23 are derived from the neutral points B, C of connection between the junctions J 2  and J 3  and between the junctions J 1 , JN, respectively. In the first step of the operation, the circuit M is supplied with only the electric current IB through the lines 21, 23 at a value of a point P enclosed by curves 24, 25. Then, current IN is supplied at a value represented by a point Q which is outside the region of the curve 24 but within the region of the curve 25. As a result, such a state is created that only one fluoxid quantum resides in the circuit M. This quantum is extinguished when the values of the currents IB and IN are changed to that represented by a point R. The predetermined circuit function is thus obtained.
