Title: Echo canceller
Inventor: YASUKAWA HIROSHI
IPC: H04B3/23
Filed: 1985-11-01
Abstract: PURPOSE:To shorten a convergence time from an echo canceler through small hardware by using a noncorrelation signal calculated from a variable loop gain system and the primary selfcorrelation coefficient of an input signal. CONSTITUTION:The 1st register Xj is stored with continuous sample data on a receiver Rin-Rout signal. A subtracter subtracts the output Y'j of a variable coefficient filter from a transmit signal Yj to generate an error signal ej. The 1st multiplier multiplies the signal ej by the output primary forecasting residue signal of the 2nd register and inputs the result to the 2nd multiplier. A loop gain generating circuit inputs the error signal outputted by the subtracter to generate a loop gain. This loop gain is multiplied by the output of the 1st multiplier through the 2nd multiplier. A correlation coefficient calculating circuit, on the other hand, calculates the correlation between a receive signal and its primary delay signal. A noncorrelation circuit subtracts the signal obtained by multiplying one delay signal by a correlation signal from the receive signal and sends its output to the 2nd register. A coefficient updating circuit inputs the output of the 2nd multiplier and updates a coefficient.

Title: Single magnetic flux quantum circuit
Inventor: SUZUKI HIDEO
IPC: H01L39/22

Abstract: PROBLEM TO BE SOLVED: To reduce the space factor of a passive transmission line and to reduce the chip area by configuring a receiving circuit so that an input impedance can be greatest on the first stage and an equivalent impedance can be reduced toward following stages. SOLUTION: In a receiving circuit 10 composed of a Josephson transmission line in (n+1) stage configuration, when the critical current value of a Josephson junction J41 on the first stage is defined as Ic, the critical current value of a Josephson junction J42 on the second stage becomes βIc, the critical current value of a Josephson junction J4k (k is an integer from 1 to n) is βk-1Ic and the critical current value of a Josephson junction in the poststage is set so as to be enlarged by a factor of β for every stage.  Thus, the circuit is also functioned as an impedance transformed with which the input impedance is enlarged toward the first stage and the equivalent impedance is reduced toward the poststage, even when the characteristic impedance of a passive transmission line 9 is great, impedance matching with the receiving circuit 10 is attained and a single magnetic flux quantum inputted to a driver circuit 8 can be transmitted to a poststage circuit.
