Abstract
1348501 Electric watches JUNGHANS GmbH Gebr 19 April 1971 [27 Feb 1970] 20629/71 Heading G3T [Also in Division H1] A Piezo-electric tuning fork, possibly of quartz, and intended for use in watches has its arms 11, 12, mechanically decoupled from its mounting 15 by narrow portion 13e and an elastic member 14. Member 14 may be T-shaped, in the form of a simple plate (41) Fig.4 (not shown) inserted into a slot in the base of the fork, or in the form of two parallel plates (30), (31) Fig. 3 (not shown). Narrow portion 13e also reduces the effect of leads 20, 21 on the resonant frequency. Member 14 is preferably more resilient than portion 13e and arranged in such a way that it is considerably more resilient than portion 13e in the direction of oscillation of the arms i.e. along Z, Fig.2. The resiliency of member 14 should normally be comparatively small in the direction X, Fig.2, perpendicular to the direction of oscillation. Electrodes 16-19 and 24 are formed by vapour deposition through a mask or some similar process and may be disposed only on those surfaces of the arms parallel to the direction of oscillation as shown (and in the embodiment of Fig. 9, (not shown)) or on all the surfaces of the arms (embodiments of Figs.3-7, (not shown)). Power supply leads 20, 21, are soldered to the electrodes 16, 17 and 18, 19 respectively, member 14, if conductive, e.g. of steel, being soldered at 25 to electrode 24 and therefore constituting a further lead. Weights 22, 23 may be provided on the arms and are easily removed or eroded to facilitate either balancing of the arms or fine adjustment of the resonant frequency. The further embodiments Figs.3-9, (not shown) have electrodes disposed in various configurations about the arms. The tuning fork may be hermetically sealed in a housing possibly of steel Fig.10 (not shown), the housing being evacuated or filled with a gas.
