Abstract : Research is being directed toward the development of advanced parametron elements, configurations, circuit arrangements, and modes of operation suited to perform logic functions in data processing sub-systems. Emphasis is placed on the realization of reliable magnetic-film parametrons which lend themselves to large scale production at low cost. A part of the parametron design effort was a study of demagnetizing fields, which points to the feasibility of small coils with 3 by 3 mm film elements. Inductance measurements and operational tests of parametron coils have, so far, led to an optimum design having 34 turns of No. 44 wire. However, an effort is underway to reduce the number of turns, since the capacitance required for resonance at the 25-Mc signal frequency is small compared to the estimated wiring capacitance. A model incorporating proposed packaging techniques was constructed. The techniques include a printed circuit board for logic interconnections, a ground plane which both completes the logic signal paths and shields the signal circuits from the pump fields, and a miniature printed circuit parametron component board.
