    摘要： Magnetic bubble domains are propagated in a magnetic medium in a desired direction using in-plane magnetic fields which are time varying but which have no spatial gradients. In applications such as information storage, the need for conventional propagation structures, such as offset conductor loops, patterned magnetic elements, and patterned ion implantation regions is reduced. Bubble domains having unwinding pairs of Bloch lines in their wall magnetization can be moved by applying appropriate in-plane magnetic fields, without the need for spatial gradients or variations in the magnetic field normal to the plane of the magnetic medium. The continuous movement of these bubble domains occurs by a cyclic process where the Bloch lines switch between two configurations, in an asymmetric way in response to the time varying in-plane field.

    摘要： A technique for controllably providing state conversions between bubble domains having a common winding number S is described. In particular, controlled conversions between bubble domains having winding number S=1 is achieved by the application of spatially invariant, homogeneous magnetic fields. For the conversion of .sigma. bubbles (having two vertical Bloch lines) to .chi. bubbles (having no vertical Bloch lines), an in-plane field is not required and only a time varying perpendicular z-field is used. For conversion of a .chi..sub.+ bubble to a .chi..sub.- bubble, and vice versa, a time varying field pulse is applied, there being no requirement for an in-plane magnetic field. However, for the conversion of .chi. bubbles to .sigma. bubbles, an in-plane field is used simultaneously with a time varying z-field. For all controlled conversions, the applied magnetic fields do not have spatial gradients. The magnitudes of the applied magnetic fields and the rise and fall times of the z field are controlled within certain ranges in order to have controlled conversion of one state to another.

    摘要： The present disclosure relates to the field of drilling equipment for the discovery and production of hydrocarbons from the earth. In particular, this disclosure relates to a torque reaction device for coupling a pipe running tool to a top drive assembly on a drilling rig. In one embodiment, a system for coupling a pipe segment to a pipe string includes a top drive assembly, a pipe running tool, and a torque reaction device. The top drive assembly includes an output shaft and a link extending from the top drive. The top drive is operative to rotate the output shaft with respect to the link. The pipe running tool is coupled to the output shaft and is engageable with a pipe segment to transmit torque from the output shaft to the pipe segment. The torque reaction device couples the pipe running tool to the link.
