Abstract

PURPOSE:To simplify the manufacutring process of a helix type delayed wave circuit and improve its yield by making active metal adhere on the surface of a dielectric bar by the dry type plating method. CONSTITUTION:Gold or copper plating is applied by several mum on the surface of a helix 4 consisting of molybdenum tape and a waxing material layer 7 is formed. On the other hand, a titanium or zirconium deposited film 8 of some thousand angstrom in thickness is coated on the surface of a dielectric bar 3 by the vacuum deposition method and a gold or copper deposited film of some thousand angstromes in thickness is further coated on it to form a waxing material layer 9. The helix 4 and the dielectric bar 3 on which each metallic layer is coated are combined using a proper jig, heated in vacuum, and waxed by solid-phase diffusion. As a result, a helix type delayed circuit is obtained by inserting the helix 4 and the dielectric bar 3 joined by diffused waxing in a metallic cylindrical enclosure 2.
