First Claim
Patent Images
1. An open coil field network comprising:
- at least first and second core means aligned in substantially adjacent planes with respect to one another;
coil means having terminal means,said coil means wound respectively around each of said first and second core means;
said terminal means adapted to receive a signal to energize said coil means and thereby induce a magnetic field between said adjacent first and second core means having a planar direction substantially coincident with that of said core means; and
at least one magnetic bubble domain device disposed in the induced magnetic field between said adjacent first and second core means.

Abstract
A unique and compact open coil rotating magnetic field network structure to efficiently package an array of bubble domain devices is disclosed. The field network has a configuration which effectively enables selected bubble domain devices from the array to be driven in a vertical magnetic field and in an independent and uniform horizontal rotating magnetic field. The field network is suitably adapted to minimize undesirable inductance effects, improve capabilities of heat dissipation, and facilitate repair or replacement of a bubble device.

9. In combination:
-
at least one core means; first and second coil means having terminal means; said first and second coil means orthogonally wound with respect to one another around said at least one core means; first and second non-magnetic shield means aligned in substantially parallel planes with respect to one another; said terminal means adapted to receive a signal to energize said coil means and thereby induce a uniform magnetic field between said core means and said first and second shield means; and at least one magnetic bubble domain device disposed outside the windings of said first and second coil means and between said core means and at least one of said first and second shield means in the region of said induced magnetic field. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
