Kind Code:
A
Abstract:
A transmission system for magnetic bubbles in a magnetic plate by use of a number of hold sections closely disposed on the magnetic plate, in which the hold sections are drive sections excited by three phase drive currents. The drive sections are formed into a cascade arrangement of a plurality of unit circulating loops, each of which comprises three drive sections excited respectively by the three-phase drive currents and disposed adjacently to one another, so that a magnetic bubble circulates in each of the unit circulating loops while a magnetic bubble held in a drive section (excited by a drive current of phase I by way of example) of a unit circulating loop can be shifted to a drive section (excited by a drive current of phase II succeeding to the phase I) of an immediately adjacent circulating loop. If an input magnetic bubble is applied to one of the unit circulating loops, an output magnetic bubble can be simultaneously obtained from another of the unit circulating loops by successive shift of magnetic bubbles from a preceding one to a succeeding one of the unit circulating loops. The drive sections may be formed into an alternate cascade arrangement of the unit circulating loops and auxiliary drive sections.
