Abstract
Magnetic bubble functional elements are implemented by aperture patterns in a single layer of electrically-conducting material. The operations of the elements are compatible with single-level conductor driven bubble memories described in A. H. Bobeck patent applications, Ser. Nos. 857,921 now U.S. Pat. No. 4,143,419 issued Mar. 6, 1979 and 856,925, filed Dec. 6, 1977, and in A. H. Bobeck-F. J. Ciak patent application, Ser. No. 899,578, filed Apr. 24, 1978 now abandoned.
