Title: Methods and apparatus for switching magnetic material
IPC: H03K17/84
Filed: 1957-11-18
Abstract: 845,604. Circuits employing bi-stable magnetic elements. SPERRY RAND CORPORATION. Nov. 18, 1957 [Dec. 7, 1956], No. 35905/57. Class 40 (9). [Also in Groups XIX and XXXV] A magnetic core storage element comprises a deposit of magnetic material having a square hysteresis loop and an easy direction of magnetization and superposed printed windings producing two magnetic field components, one in and one transverse to the easy direction, the switching of the core along the easy direction being facilitated by the transverse component. As shown in Fig. 8, a magnetic deposit 56 on a glass plate has superposed thereon a sense winding 58, two coincident current windings 60, 62, an inhibit winding 64 and a transverse field winding 66, producing fields as indicated at 78, 80, 94, and 76. Energization of the inhibit winding cancels one of the fields 78, 80 to prevent switching. The winding deposits may be divided as shown to prevent eddy currents, and the printed leads may be angularly displaced when the winding itself may also be displaced to give correct orientation to the field. Windings may be disposed both above and below the magnetic deposit, which may have single domain thickness. The winding 66 may be continuously biased to provide triple order coincident selection. The windings may be printed on bases of rubber-based phenolic resin or " Mylar " (Registered Trade Mark). Memory matrix.-In Fig. 11 is disclosed a matrix comprising magnetic elements 144, a sense winding on base 148, column and row windings on bases 150 and 152 and an inhibit winding on base 154. The sense column and row windings are shown more clearly in Figs. 12, 13 and 14, respectively. A magnetic layer 160 partially completes the flux path. The magnetic elements are formed with their easy directions at an angle # so that a separate transverse field winding is unnecessary. Fig. 15 shows a different sense winding in which the conductors are displaced at an angle a to eliminate noise effects.
