Abstract

A lumped constant type electromagnetic delay line employs an inductive device consisting of a plurality of turns of electroconductive wire in combination with chip capacitors connected to a plurality of taps provided in the inductive device so as to form a ladder circuit consisting of a plurality of delay circuit sections. The coil wire ends and the taps of the inductive device of the present invention are all twisted and extended in the same direction, and are all provided with a uniform and sufficient rigidity. Therefore, the process of connecting these taps and coil wire ends to the corresponding electrodes is simplified, and is therefore made better adapted for automatization. During the process of manufacture, a series of inductive devices can be fabricated as a continuous process of winding a coil wire around an elongated bobbin, and all the taps and coil wire ends are laterally extended and twisted in the same manner so that the entire process is significantly simplified. After the process of winding the continuous coil and extending the taps, the continuous bobbin is cut into individual inductive devices.
