VARIABLE-INDUCTION PICKUP Russian patent published in 1994 - IPC

FIELD: electrical engineering. SUBSTANCE: variable-induction pickup has printed-circuit board on which layers flat spirals are placed in pairs in opposition to each other. Inner turns of spirals are interconnected via lands and junction metallized holes made in them. Vertical current-conducting wires to which outer turns of spirals of matrix columns are connected are arranged in first layer along matrix columns. Horizontal current-conducting wires to which outer turns of spirals of matrix lines are connected are positioned in second layer of printed circuit board along matrix lines. EFFECT: facilitated manufacture. 5 dwg
