摘要： Piezoelectric ceramics containing PbO and TiO.sub.2 as its principal constituents, and further containing 0.5 to 3.7 mol-% of Nd.sub.2 O.sub.3 and 0.2 to 1.5 mol-% of MnO.sub.2. Since the piezoelectric ceramics is low in the dielectric constant and is especially small in the temperature coefficient of the delay of surface acoustic waves, it is suitable for a surface acoustic wave device. Piezoelectric ceramics in which 0.3 to 3.3 mol-% of In.sub.2 O.sub.3 is further added to the above-mentioned composition has a still smaller temperature coefficient of the delay of surface acoustic waves, and it is also possible to make this coefficient zero.
摘要翻译：含有PbO和TiO2作为主要成分的压电陶瓷，还含有0.5〜3.7mol％的Nd2O3和0.2〜1.5mol％的MnO2。由于压电陶瓷的介电常数低，表面声波延迟的温度系数特别小，所以适用于表面声波装置。在上述组合物中进一步添加0.3〜3.3mol％的In2O3的压电陶瓷的表面声波的延迟温度系数更小，也可以使该系数为零。

摘要： An apparatus for and a method of non-destructively determining properties of a SAW substrate, in which first and second interdigital transducers are formed in a spaced relationship on a single common piezoelectric substrate, a blocking member is formed between said transducers on the substrate for preventing an acoustic wave signal from being transferred between said transducers via the common substrate, spacers are provided for supporting a to-be-determined SAW substrate above the common substrate with a spacing left between the SAW substrate and the fingers of transducers, the SAW substrate to be placed on the spacers is positioned with respect to the transducers so that co-directional mode coupling will, in operation, effectively take place between the SAW substrate and the transducers, adherence between the SAW substrate and the spacers is secured to enhance the co-directional mode coupling, an electric signal is applied to the first transducer for transferring, due to the co-directional mode coupling, an acoustic signal to the SAW substrate along the surface of which the acoustic signal will propagate and will be transferred, due to the co-directional mode coupling, to the second transducer, and the output of the second transducer is measured.
