Abstract

1,088,682. Transformers. OSHIMA MUSEN CO. Ltd. June 2, 1965 [June 10, 1964], No. 23520/65. Heading H1T. A flexible synthetic resin holder has a plate portion 10c (Fig. 2) engaging the under surface of an insulating base-plate 2 to which there is bonded a core piece 4 with a winding 5, and integral opposed holding portions 10a, 10b extending beyond opposite sides of the plate 2, said portions 10a, 10b being internally threaded to receive an externally threaded movable cylindrical core piece 8. The holder plate 2 and core pieces 4 and 28 are fitted into a metal case 1 having an aperture 1a through which a screwdriver can rotate the core piece 8, relative rotation between case 1 and the holder being prevented by opposed lips 16a, 16b punched in the case 1. A recess 17 formed in the baseplate 2 may house a tuning capacitor 18 connected to the winding 5 to provide a resonant circuit.
