    • PROBLEM TO BE SOLVED: To provide a SAW sensor capable of measuring both of distortion and temperature by one SAW device.SOLUTION: A SAW device 1 is arranged on one surface 201 of a measurement object 20, and structured so that an area 102a which is located right under a propagation path 13 of a substrate lower surface 102 of the SAW device 1 is fixed to the measurement object 20, and areas 102b, 102c which are located right under a drive electrode 11 and a reflector 12 of the substrate lower surface 102 are not fixed to the measurement object 20. In this structure, when distortion is generated in the measurement object, the distortion is generated only on the propagation path 13 on a substrate upper surface, and phase variation is generated in surface acoustic waves reflected by the reflector 12. Since the phase variation at this time is hardly affected by temperature variation, the distortion of the measurement object can be measured from the phase variation. In addition, in this structure, since a resonance frequency of the SAW device 1 varies due to the temperature variation, and is not affected by the distortion of the measurement object, temperature can be measured from variation of the resonance frequency.
    • 要解决的问题:提供一种能够通过一个SAW器件测量失真和温度两者的SAW传感器。 解决方案:SAW器件1布置在测量对象20的一个表面201上,并且构造成使得位于SAW器件1的衬底下表面102的传播路径13正下方的区域102a被固定 并且位于驱动电极11正下方的基板下表面102的反射体12的区域102b,102c不固定在测量对象20上。在该结构中,当在测量中产生失真时 目的是仅在基板上表面的传播路径13上产生失真,并且由反射器12反射的表面声波产生相位变化。由于此时的相位变化几乎不受温度变化的影响,因此, 可以从相位变化来测量测量对象。 此外,在该结构中,由于SAW器件1的谐振频率由于温度变化而变化,并且不受测量对象的变形的影响,因此可以根据谐振频率的变化来测量温度。 版权所有(C)2013,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a power-transmitting device for transmitting power with high transmission efficiency even if a transmission distance between a power transmission resonance coil and a power receiving resonance coil is changed, and to provide a power-receiving device and a power transmission system.
      SOLUTION: In the power-transmitting device 24, a position of the center of gravity O2 of a power transmission pickup coil 23 is adjusted, thus changing a state of magnetic flux passing through the inside of an outer enclosure of the power transmission pickup coil 23 in magnetic flux generated by the power transmission resonance coil 22, and hence increasing or decreasing a boosting ratio of the power transmission resonance coil 22 to the power transmission pickup coil 23 to adjust an impedance ratio of the power-transmitting device 24. In the power-transmitting device 24, the impedance of the power transmission pickup coil 23 seen from the power transmission resonance coil 22 is adjusted by changing the state (interlinkage state) of the magnetic flux passing through the inside of the outer enclosure of the power transmission pickup coil 23, thus maintaining high transmission efficiency η.

    • PROBLEM TO BE SOLVED: To allow more effective use of the energy of surface acoustic waves than conventional types, in a flat planar type surface acoustic wave element forming electrodes on a flat plane of a substrate. SOLUTION: The surface acoustic wave element forms an IDT3, which can generate or receive surface acoustic waves, and a reflector 4 on the flat plane of the substrate 2. The IDT3 is constituted, by arranging a plurality of electrodes 11 of circular shapes enclosed by curve lines concentrically and at predetermined intervals. Moreover, the reflector 4 is constituted, by arranging a plurality of electrodes 12 concentrically of the shapes which are identical to that of the first electrode 3 and at predetermined intervals with respect to the IDT3. According to the method, generation of diffraction phenomena can be suppressed, and the energy of the surface acoustic waves can be used effectively, as compared to conventional types, since the shapes of the IDT3 and the reflector 4 are of enclosed circular shapes in which end parts do not exist.
