Magnetic thin film shift register having unidirectional transmission elements
Abstract
Abstract A DIGITAL SHIFT REGISTER PROPAGATING INFORMATION AS REGIONS OF REVERSE MAGNETIZATION HAS A SUCCESSIVE ARRANGEMENT OF A FIRST BIDRECTIONAL TRANSMISSION ELEMENT FOR RECIPROCAL PROPAGATION OF THE MAGNETIC REGION, A FIRST UNIDIRECTIONAL TRANSMISSION ELEMENT FOR NON-RECIPROCAL PROPAGATION OF THE MAGNETIC REGION, A SECOND BIDIRECTIONAL TRANSMISSION ELEMENT, AND ANOTHER UNIDIRECTIONAL TRANSMISSION ELEMENT IN EACH OF A SERIES-SUCCESSION OF STAGES, WITH ALL UNIDIRECTIONAL TRANSMISSION ELEMENTS HAVING THE SAME DIRECTION OF FORWARD PROPAGATION. A MAGNETIC FIELD SOURCE APPLIES A MAGNETIC FIELD TO THE TRANSMISSION ELEMENTS TO ADVANCE REGIONS OF REVERSE MAGNETIZATION FROM ONE BIDIRECTIONAL ELEMENT, THROUGH THE UNIDIRECTIONAL ELEMENT IN THE FORWARD DIRECTION, TO THE NEXT BIDIRECTIONAL ELEMENT. A FURTHER MAGNETIC FIELD ERASES THE REGIONS OF REVERSE MAGNETIZATION FROM THE ELEMENTS IN EACH STAGE EXCEPT THAT IN ONE INSTANCE THE REGIONS PRESENT IN THE FIRST BIDIRECTIONAL ELEMENTS ARE NOT ERASED AND IN ANOTHER INSTANCE THE REGIONS IN THE SECOND BIDIRECTIONAL ELEMENTS ARE NOT ERASED.
