摘要： 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.

摘要： The present invention includes a three-dimensional base body (40) having a curved surface allowing definition of a circular orbital band (B), an electroacoustic transducer (21) arranged on the orbital band (B) of the three-dimensional base body (40) and configured to excite surface acoustic wave to perform multiple roundtrips along the orbital band (B), and a sensitive film (25) formed on at least a part of the orbital band (B) of the three-dimensional base body (40) and configured to react with a specific gas molecule. The surface acoustic wave experienced the multiple roundtrips along the orbital band (B) is then converted into a high frequency electric signal again by an interdigital transducer (21). The resulting high frequency electric signal is transferred to a detection/output unit (24) via a switching unit (23) and then detected by the detection/output unit (24).

摘要： The present invention relates to an elastic surface-wave device, and more particularly to an elastic surface-wave device of a greatly increased performance, compared with a prior art elastic surface-wave device, and which is compact. The elastic surface-wave device includes a substrate including a surface having a region which is formed by at least a part of a spherical surface and is circularly continuous, and a surface acoustic wave generator which is provided in the surface region of the substrate and generates surface acoustic waves propagating in a continuous direction of the surface region. The surface acoustic wave generator generates surface acoustic waves in such a manner these waves can propagate only in the continuous direction without being diffused in a direction crossing the continuous direction along the surface region.
