Abstract: An on-chip current regulator for a superconducting logic circuit isolates the superconducting logic circuit from external noise, reduces the effects of process fluctuations on the performance of the logic circuit and significantly reduces total circuit power requirements. The on-chip current regulator in accordance with the present invention includes one or more hysteretic Josephson junctions each connected in parallel with a resistor forming a resistively shunted junction (RSJ) or includes a self-shunting junction. One RSJ may be coupled between an off-chip current regulator and the hysteretic Josephson junction that functions as a current limiting resistor and provides improved isolation from external noise.

Abstract: An end portion of a multiconductor cable (16, 18) is formed about an edge portion (28) of a sheetlike core (27) with portions of bared cable conductors (26) facing outwardly. The other cable (20, 22) is similarly arranged about an edge of a core (34). On the connector parts- (12, 14) being mated the bared cable conductors of cable (16, 18) are brought into contact with the bared conductors of cable (20, 22).
