Logical element

Claim 1

A LOGICAL ELEMENT COMPRISING FOUR MAGNETIC CORES HAVING RECTANGULAR HYSTERESIS CHARACTERISTIC, EACH OF THE FOUR CORES BEING PROVIDED WITH SIGNAL INPUT COILS OF ODD NUMBER, A WRITING AND RESETTING COIL, AND AN OUTPUT COIL, THE COILS OF THE SAME KINDS VEING CONNECTED IN SERIES TO FORM, RESPECTIVELY, INPUT WINDINGS, A WRITING AND RESETTING WINDING AND AN OUTPUT WINDINGS, AND ALL THE SAID COILS VEING WOUND ON RESPECTIVE CORES IN SUCH A MANNER THAT THREE KINDS OF THE COILS OF ONE CORE ARE WOUND ON SAID CORE IN THE SAME DIRECTION, ONE OF THREE KINDS OF THE COILS OF EACH OF THE OTHER THREE CORES IN WOUND IN THE DIRECTION REVERSE TO THOSE OF THE REMAINING TWO KINDS OF THE COILS AND EACH OF SAID INPUT WINDINGS WRITING AND RESETTING WINDING AND OUTPUT WINDING INCLUDES ONE OF SAID REVERSELY WOUND COILS; ERASING COILS WOUND ON EITHER ONE PAIR OF TWO PAIRS OF THE FOUR MAGNETIC CORES, THE RESPECTIVE INPUT AND OUTPUT COILS OF THE SAID PAIR OF CORES HAVING THE SAME WINDING DIRECTION, ONE OF THE SAID ERASING COILS BEING WOUND ON THE SAME DIRECTION AS THE INPUT COIL OF THE SAME CORE AND THE OTHER OF SAID ERSING COIL OF THE SAME CORE; A RESET PULSE CURRENT MEANS INPUT COIL OF THE SAME CORE; A RESET PULSE CURRENT MEANS SUPPLYING A RESET PULSE CURRENT TO THE WRITING AND RESETTING WINDING FOR MAGNETIZING TWO CORES TO A SIMILAR POLARITY AND THE OTHER TWO CORES TO THE OPPOSITE POLARITY; WRITING PULSEL CURRENT MEANS SUPPLYING, AFTER SAID RESET PULSE CURRENT, A WRITING PULSE CURRENT FOR PRODUCING A MAGNETIC FORCE EQUAL TO CORECIVE MAGNETIC FORCE OF EACH OF THE SAID MAGNETIC CORES TO THE WRITING AND RESETTING WINDING IN THE DIRECTION OPPOSITE TO THAT OF SAID RESET PULSE CURRENT; INPUT SIGNAL PULSE CURRENT MEANS IMPRESSING SIMULTANEOUSLY WITH THE SAID IMPRESSION OF SAID WRITING PULSE CURRENT, INPUT SIGNAL PULSE CURRENTS HAVING, RESPECTIVELY, THE SAME AMPLITUDE AND A POSITIVE OR NEGATIVE POLARITY CORRESPONDING TO THE DECISION BY MAJORITY OF THE INFORMATION SIGNALS TO THE SIGNAL INPUT WINDINGS, WHEREBY MAGNETIZATIONED STATES OF ONLY TWO CORES AMONG FOUR CORES ARE CHANGED AND THOSE OF THE OTHER TWO CORES ARE UNCHANGED, THUS CAUSING THE WRITING OF THE INFORMATION SIGNALS IN THE FORM OF POLARITY OF THE RESIDUAL MAGNETIZATION; AND READ-OUT PULSE CURRENT MERANS IMPRESSING A READING-OUT PULSE CURRENT TO THE ERASING WINDING FOR INDUCING AN ELECTRIC VOLTAGE ACCORDING TO POSITIVE OR NEGATIVE POLARITY OF THE WRITING CONDITION IN THE ONE OR THE OTHER OF THE OUTPUT COILS WOUND ON THE CORES HAVING THE ERASING COIL WHEREVY AN OUTPUT PULSE CURRENT HAVING A POSITIVE OR NEGATIVE POLARITY IS OBTAINED AT THE TERMINALS OF THE OUTPUT WINDING, SAID RESET PULSE CURRENT MEANS BEING IMPRESSED, THEREAFTER FOR RESETTING THE MAGNETIC CORES.
