Abstract

A switching system for a bidirectional propagating device includes a skyhook element in a minor loop corner. As shown in the drawing, the switching system 10 has a Y-bar type switch 12, an I-bar element 14, and a skyhook element 16 having an end portion 17 positioned between elongated bar elements 18A and 18B. A conductor 20 is used for switching the bubble from the switch 12 to the I-bar 14.

Switch Design for Bidirectional Propagating Bubble Device

A switching system for a bidirectional propagating device includes a skyhook element in a minor loop corner. As shown in the drawing, the switching system 10 has a Y-bar type switch 12, an I-bar element 14, and a skyhook element 16 having an end portion 17 positioned between elongated bar elements 18A and 18B. A conductor 20 is used for switching the bubble from the switch 12 to the I- bar 14.

A bubble is switched from position A on Y-bar switch 12 to position B on I-bar element 14 and then to position C on skyhook element 16 by pulsing a current in conductor 20. The bubble continues under the influence of a clockwise rotating inplane magnetic field to move to position D and then E on skyhook element 16. Once the bubble is in the minor loop at position E, Bubbles will propagate around the corner from G to E to F in one direction, and from F to E to G in the other direction. Whereas prior-art corner elements permitted bubbles to move near I- bar element 14 causing strip out from that position, the skyhook element 16 does not permit bubbles in the minor loop to propagate near the I-bar element 14.
