摘要： A drive system for a coincident-current magnetic core memory is disclosed which employs a fewer number of transistors to steer drive current of proper polarity through a selected line for read and write cycles. The lines are grouped into 2N groups of S lines, and the groups are associated in pairs. A given pair of groups is cross-coupled to the emitters of one of N pair of transistor switches by diodes, each poled for forward conduction when one of the transistors is activated depending upon both the direction of current flow desired and the group in which the particular line to be driven is. A voltage is applied to the activated transistor of proper polarity for the drive current, and one of S bipolar drive current sources is activated to uniquely drive current through the particular line in the desired direction.

摘要： Armatures of a printed-circuit form are produced on a woven glass fiber tube formed on a mandrel, plating a layer of conductive material on the tube, etching a plurality of grooves to form a first pattern of conductors, repeating the first four steps with a shorter tube of woven glass fiber to provide a second pattern of conductors insulated from the first, but connected thereto through rings of conductive material formed at each end by plating directly over end rings of the first pattern, and cutting axial slots in the end rings to a depth sufficient to disconnect adjacent parallel conductors of each pattern leaving juxtaposed ends of conductors at the ends. For a rigid armature, the layers of woven glass fiber are impregnated with a resin which is rigid when cured and for a flexible armature, with a resin which is flexible when cured.

摘要： Apparatus for contacting the miniature terminal pads of an integrated circuit, including a frame having a pair of thin glass sheets held a small distance apart by a thin spacer that extends along most of the periphery of the sheets, and a blade of thin conductive sheet material located between the sheets. The blade has a rear end with a recess that receives a bump formed on the spacer for pivotally mounting the blade on the spacer, and the blade also has a thin spring arm that bears against the spacer to urge the blade into firm pivotal engagement with the spacer bump and to bias the blade towards one direction of pivoting.

摘要： A matrix of magnetic cores is strung with electric wires by first laying the wires along with needles attached to their front ends on adhesive tape. The tape is pulled to advance the needles and wires towards the matrix, but the tape passes over an edge so that it separates from the needles and the needles then pass through rows of magnetic cores of the matrix.

摘要： A magnetic core memory line sink voltage stabilization system is disclosed using a current or voltage source to charge a group of selected lines. The sink ends through which the lines are charged are terminated with the approximate characteristic impedance of all lines connnected at their sink end to a common junction, and a balanced transformer is employed to keep the potential of the junction substantially constant when a current pulse is applied at the drive end of a selected pulse. The primary of the transformer is connected in series with a current pulse source, and the secondary is connected in parallel with the terminating resistor. The turns ratio of the transformer and polarity of the secondary winding are so selected as to inject a current into the common junction substantially equal to that driven through the line by the current pulse source, and of proper polarity, to maintain the potential of the common junction substantially constant.

摘要： Amplitude of a fast-rise pulse current is stabilized under varying load conditions by a transformer having a first winding connected in series between a pulse voltage source and a variable load. A square loop hysteresis core of the transformer is biased with regulated DC current in a second winding through a choke coil which stores energy while the bias field is being overcome by a voltage pulse, and restores energy to a power supply for the current pulse source at the end of the current pulse. In a core memory plane, the bias current source services current pulse sources of both polarities for all drive lines and adjacent bit lines are paired with current sources of opposite polarities during read and write cycles to provide tight controlled current loops. Positive and negative energy is returned to the power supply from the choke coil in a substantially balanced manner for both bit (y) and word (x) drive lines.
