Abstract: PURPOSE:To improve the temperature characteristic, to attain low loss and to increase the attenuation by providing an input electrode and an output electrode on both major sides of a piezoelectric substrate so as not to be opposite to each other, and forming an earth electrode in the middle layer of the piezoelectric substrate between the input electrode and the output electrode. CONSTITUTION:An earth electrode 2 is formed to the central layer of the piezoelectric substrate 1 in the internal broadwise direction, an input electrode 3 is provided to the major side of the piezoelectric substrate 1 opposite to a half side of one side of the earth electrode 2 and an output electrode 4 is provided to the rear major side opposite to other half side of the earth electrode 2. The input and output electrodes 3, 4 have the same electrode area and arranged symmetrically while being deviated to each other to avoid overlapping, then the vibration of the symmetrical mode and the asymmetrical mode is caused as a dual mode resonator. Moreover, since the earth electrode 2 is formed on the center layer of the thickness of the piezoelectric substrate 1, a double wave vibration having a wavelength of 1/2 of a fundamental wave is stimulated. Thus, a piezoelectric substrate material whose poisson ratio is 1/3 or below is used to improve the temperature characteristic, to attain low loss and to increase the attenuation or the like.

Abstract: PURPOSE:To increase the detecting accuracy and at the same time to decrease the power consumption for a flat plate type position detector, by detecting the potential of a conductive electrode which is in contact with plural thin electrode elements and ten detecting the pressed position. CONSTITUTION:An electrode plate 6 is formed in a plane form by laminating alternately the thin electrode elements 3-1-3-n and 5-1-5-n and the thin insulated members 4-1-4-n. A conductive plate 7 is in close contact with the plate 6. Then the different potentials are applied to those thin electrode elements respectively by means of a means such as a resistance voltage dividing circuit, etc. Thus the potential of the thin electrode element is transmitted to the plate 7 at the pressed area and only when pressure is applied. The pressed position is detected by detecting the potential of the plate 7. As a result, the equipotential line distribution can be set at each part within the position detecting surface in an accurate, parallel and even way.
