Abstract: A clock signal supply system provides for automatic accurate phase adjustment of clock signals. The system includes an oscillator that produces clock signals and a reference generator that generates a reference signal that has a predetermined relationship with respect to the clock signals produced by the oscillator. At each location where the clock signal is to be received, an adjusting circuit is provided to adjust the phase of the received clock signals. Such an adjusting circuit may include a variable delay circuit which receives the clock signal and produces an output which is constituted by the clock signal having a varied delay, to the remainder of the attached circuits. Further, the output of the variable delay is fed back to a phase difference detection circuit. The reference signal is second input to the phase difference detection circuit.

Abstract: A superconducting logic circuit is configured by using two kinds of input-output type quantum flux parametrons (QFP), that is, a periodically excited input-output type QFP and an arbitrarily excited input-output type QFP. The periodically excited QFP is excited by periodically varying exciting magnetic flux to amplify a binary magnetic flux. The arbitrarily excited QFP is excited by magnetic flux output signals of upstream QFPs.

Abstract: A connector structure comprising an electrically conductive plate having a plurality of through holes formed therein, an electrically insulated film formed on the inner wall of at least one of the through holes, an electrically conductive film formed on the inner wall of at least one other through hole, and an electrically conductive material of a low melting point provided within the through holes. The low melting point material provided in the through holes whose inner walls are coated with an electrically insulating film is insulated from the electrically conductive plate and such through holes may serve to receive signal propagating pins.

Abstract: A semiconductor integrated circuit structure including a semiconductor substrate having a large area adapted for a large scale integration, a circuit formed in the substrate for generating a pair of complementary signals, a pair of common potential level layers with an electrically insulating layer interposed therebetween, the common potential level layers being formed above and being electrically insulated from the substrate, and a pair of electric conductor pattern layers formed in the insulating layer for conducting the pair of complementary signals. The electric conductor pattern layers are arranged so as to be overlapped with each other in a direction substantially perpendicular to the large area substrate and so as to be substantially parallel with the large area substrate.
