Abstract
1313622 Watches SUWA SEIKOSHA KK 19 April 1971 [31 March 1970] 24342/71 Heading G3T In an electric timepiece having a balance comprising discs 21 which carry two pairs of magnets 23, 24 and 25, 26 to co-operate with driving and detecting coils 27, 28 respectively, the detecting coil 28 is so arranged that the peak values, e.g. V pos , V' pos , of the double and single pulses of voltage induced therein are substantially equal. The coils 27, 28 are wound concentrically on a frame with the detecting coil 28 comprising relatively few turns of relatively thick wire. The coils have a common terminal (31), Fig.6 (not shown) and may be used in a known transistor circuit see Fig. 3 (not shown).
