Compact converter for magnetic bubble domains - has five magnetic element carriers with H:sections and I:sections to manipulate bubbles between various rest positions

摘要

Magnetic bubbles are moved into alternative paths by units containing four magnetic poles, defining resting points (1-4) for magnetic bubbles along a path (AB) which may be transferred to alternative points (1'-4') in an alternative path (CD). Movements are initiated by a rotating magnetic field. The paths are defined by H-section (10, 12) and I-section (14, 15). Field changes at domain boundaries are synchronised by a multiplexed signal system which causes the bubbles to be controlled on the first path by the first and third pole signals and on the second path by the second and fourth pole signals. All components are mounted on an integrated ship configuration.
