Abstract: The present invention relates to a circuit controlling terminal equipment identifiers identifying said terminal equipment in a communicating apparatus wherein a number of the above-mentioned terminal equipment are connected to a network, and makes it possible to reduce the amount of hardware make the operation faster and facilitate the control of TEI assignment by using the address of a memory storing binary data as the TEI value.

Abstract: This invention relates to a standard cell system large scale integrated circuit which comprises arraying a plurality of standard cells that are equally dimensioned in at least one direction and interconnection said standard cells so as to constitute a logic device, whereby the improvement is characterized in that wiring carrying a heavy load and being connected at many places on the surface of the chip is located within each of the standard cells, furthermore said wiring carrying a heavy load and being connected at many places on the surface of the chip is a clock line, and said clock line is located between a power line and a grounding conductor provided within each standard cell.

Abstract: A superconducting integrated circuit device switches the state of a Josephson junction element in response to incident light by diverting a current to a superconducting control signal line from a superconducting control signal extracting line. The control signal extracting line becomes resistive when irradiated by a light.
