Abstract
1441192 Piezoelectric resonators DAINI SEIKOSHA KK 25 March 1974 [29 March 1973 (2)] 13098/74 Heading H1E A piezoelectric or electrostrictive laminar resonator is mounted by a layer 32 of adhesive on a pedestal 31 and is provided on one or both sides with electrodes 15, 26 which extend (e.g. at 20, 21, 22, 30) beyond the resonator. Leads are connected to the extensions of the electrodes. The resonator may be of the tuning-fork flexural type with two or three tines and Figs. 1, 2 show a typical electrode pattern. It may be made of quartz, barium titanate lithium niobate or lead zirconate. The ends of the tines 11, 12 may carry loading material 24, 25. The adhesive 32 may be raw rubber. The resonator is suitable for use in a timepiece.
