Abstract

1369302 Delay lines MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 2 March 1972 [3 March 1971 24 March 1971 (2) 31 March 1971] 9780/72 Heading H3U A delay line comprises an insulating core 10 with integral flanges 11a ... 11o between which serially-connected coil sections 13a ... 13n are wound, the ends of the overall coil formed by the sections being connected to insulated terminals 16, 17. The core 10 and flanges 11a ... 11o are coated with a conductive layer 12 preferably of silver particles bound in a resin, this layer forming one electrode of a distributed capacitor connected to a terminal 18. The other electrode of the capacitor is formed by the conductive core 14 of the wire comprising the sections 13a ... 13n and the dielectric of the capacitor is formed by resin coating 15 of the wire and by a polymer 20 with which the sections are impregnated. The delay line is mounted in a sealed insulating housing (Fig. 4, not shown).
