    • In an elastic wave device that significantly reduces and prevents deterioration of a frequency characteristic without roughening an undersurface of a piezoelectric substrate, a structure is bonded to a surface of a piezoelectric substrate other than a main surface of the piezoelectric substrate on which IDTs are located. The structure is provided so that a path difference is defined between a first component and a second component of a bulk wave that is excited by the IDT and propagates in the piezoelectric substrate toward the bonding surface. The first component of the bulk wave is reflected from the bonding surface. The second component of the bulk wave enters the structure from the bonding surface, propagates in the structure, enters the piezoelectric substrate from the bonding surface, and propagates in the same direction as that of the first component reflected from the bonding surface in the piezoelectric substrate.

    • The present invention provides a composite structure having a supporting substrate between a piezoelectric substrate and a compensation layer. The materials used to form the piezoelectric substrate and the compensation layer in isolation, have higher thermal coefficients of expansion (TCE) relative to the TCE of the materials forming the supporting substrate. Once the composite structure is created, the piezoelectric substrate and compensation layer tend to expand and contract in a similar manner as temperature changes. The expansion and contraction forces applied to the supporting substrate by the piezoelectric substrate due to temperature changes are substantially countered by similar opposing forces applied by the compensation layer, resulting in the opposing forces substantially counteracting one another. Due to the counteraction, the composite structure resists bending or warping, reducing expansion and contraction and increasing stress of the piezoelectric substrate, and thus reducing the effective TCE and TCF of the piezoelectric substrate.
    • 本发明提供了一种在压电基片和补偿层之间具有支撑基底的复合结构。 用于形成压电衬底和补偿层的隔离材料相对于形成支撑衬底的材料的TCE具有较高的热膨胀系数(TCE)。 一旦形成了复合结构,压电基片和补偿层就会像温度变化一样膨胀和收缩。 由于温度变化而由压电基板施加到支撑基板的膨胀和收缩力通过由补偿层施加的相似的相反力基本抵消,导致相反的力基本相互抵消。 由于反作用,复合结构抵抗弯曲或翘曲,减小压电基板的膨胀和收缩并增加应力,从而降低压电基板的有效TCE和TCF。

    • A surface acoustic wave device includes a three-dimensional substrate having an annular curved surface enabling to propagate a surface acoustic wave, and an electro-acoustic transducing element, which excites and propagates the surface wave along the surface, and receives the propagated surface wave. The substrate is made of a Li2B4O7, Bi12SiO20, LiNbO3, LiTaO3, or quartz crystal, and the element propagates the surface wave along a line of intersection between a crystal face of the crystal and the surface, and the line of intersection is defined as an outermost circumferential line of the surface. An environmental difference detecting apparatus uses the device having a plurality of propagating surface zones and compares surface acoustic wave reception signals of electro-acoustic transducing elements in the propagating surface zones of the device with each other, and detects an environmental difference in space portions with which the propagating surface zones come into contact.
