摘要： PCT No. PCT/JP93/01028 Sec. 371 Date Jan. 23, 1995 Sec. 102(e) Date Jan. 23, 1995 PCT Filed Jul. 23, 1993 PCT Pub. No. WO94/02911 PCT Pub. Date Feb. 3, 1994An ultrasonic touch system including a substrate and at least an ultrasonic transducing system on one end surface Z1 of the substrate. The ultrasonic transducing system comprises at least an interdigital transducer P and at least an interdigital transducer Q corresponding to the interdigital transducer P. An electric signal having a frequency approximately corresponding to the interdigital periodicity of the interdigital transducer P is applied to the interdigital transducer P, causing the acoustic wave on the end surface Z1 with a high efficiency, the acoustic wave having a wavelength approximately equal to the interdigital periodicity of the interdigital transducer P. At this time, an electric signal having a frequency approximately corresponding to the wavelength of the acoustic wave generated on the end surface Z1 is detected at the interdigital transducer Q. When touching with a finger or other things on a part of the propagation medium of the acoustic wave on the end surface Z1, the electric signal detected at the interdigital transducer Q is decreased. A touch on the substrate by a finger or other things is accordingly detected with a high sensitivity and a quick response time under operation with low power consumption and low voltage.

摘要： An apparatus for generating electric energy comprises a vibration plate, a supporting board, at least one side-wall unit and at least one piezoelectric substrate having a first- and a second end surfaces covered with a first- and a second electrodes, respectively. They all together form at least one cavity resonator. If a sound pressure from the outside arrives at the vibration plate, an acoustic vibration is excited in the vibration plate, and thereby a resonance vibration is induced in the cavity resonator. In this time, the piezoelectric substrate responds collectively to the resonance vibration. Thus, a resonance energy occurred in the cavity resonator is converted into an electric energy, which is delivered through the first- and second electrodes.

摘要： An ultrasound radiation device comprises a piezoelectric substrate, an interdigital arrangement of two comb-shaped electrodes formed on an upper end surface of the piezoelectric substrate, a counter electrode formed on a lower end surface of the piezoelectric substrate, an interdigital transducer formed on said upper end surface of said piezoelectric substrate, and an amplifier between one of the two comb-shaped electrodes and the interdigital transducer. If an electric signal is applied between the counter electrode and one of the two comb-shaped electrodes, a longitudinal wave composed of the main lobe and grating lobes is radiated into a material in contact with the counter electrode, as well as a Lamb wave is excited in the piezoelectric substrate. The Lamb wave is detected as a delayed electric signal at the interdigital transducer. The delayed electric signal is amplified by the amplifier, and used as an input electric signal again.

摘要： An ultrasonic coding modem for digital network communication comprises a transmitting device having a first piezoelectric substrate, and a receiving device having a second piezoelectric substrate. If a message digital-signal is applied to the transmitting device, a SAW is excited on the first piezoelectric substrate and is delivered as a coded digital signal into a digital network. On the other hand, if the coded digital-signal is received at the receiving device from the digital network, a SAW is excited on the second piezoelectric substrate. In this time, if the SAW excited on the second piezoelectric substrate is corresponding to the SAW excited on the first piezoelectric substrate, an output digital-signal, which is equivalent to the message digital-signal, is delivered from the receiving device. As a result, it is possible to keep a base-band communication secret.

摘要： An ultrasonic touch panel system comprises a nonpiezoelectric plate, first- and second transducer-units, first- and second detecting-units, and a signal analyzer. The first transducer-unit consists of at least two input interdigital electrodes Txi (i=1, 2, . . . , m), at least two electrode groups Gxi (i=1, 2, . . . , m), first- and second piezoelectric substrates, and at least two uniting terminals Uxj (j=1, 2, . . . , n). When a first input electric signal is applied to two neighbors of the input interdigital electrodes Txi, a first SAW is excited in the first piezoelectric substrate, respectively, and is transmitted to the second piezoelectric substrate along the upper end surface of the nonpiezoelectric plate. The first SAW is transduced to a first output electric signal at the output interdigital electrodes Rxaj and Rxbj. If touching on the upper end surface of the nonpiezoelectric plate, a first delayed electric signal appears at one of the uniting terminals Uxj, and is converted into a first burst-signal via the first detecting-unit. A touch position is sensed in terms of an amplitude condition of the first burst-signal and that of a second burst-signal caused from a second input electric signal at the second transducer-unit.

摘要： An ultrasonic liquid-crystal display comprises a nonpiezoelectric bottom-plate, a piezoelectric substrate on a first surface-part of an upper end-surface of the nonpiezoelectric bottom-plate, at least one dispersive interdigital transducer on the piezoelectric substrate, a nonpiezoelectric upper-plate, a first conducting electrode, with which a second surface-part of the upper end-surface of the nonpiezoelectric bottom-plate is covered, a second conducting electrode, with which a lower end-surface of the nonpiezoelectric upper-plate is covered, and a liquid crystal between the first- and second conducting electrodes. The nonpiezoelectric bottom-plate and the nonpiezoelectric upper-plate have a transparency, respectively. When a first electric signal is applied to the dispersive interdigital transducer, an FM chirp-SAW is excited in the piezoelectric substrate. The FM chirp-SAW transmitted to the liquid crystal causes it cloudy. Supplying the first- and second conducting electrodes with a second electric signal, that is, applying electric field to the liquid crystal, makes the liquid crystal cloudless.

摘要： A recognition system for identification-card singularity comprises an identification card, a detail communication device attached to a detail computer, and a master communication device attached to a master computer. If the identification card is set in the detail communication device, a pulse is generated at the detail communication device at regular intervals. When the pulse is applied to the identification card, an individual SAW is excited therein. The individual SAW is converted into an individual double-coded digital-signal at the detail communication device and delivered into a digital network. When the individual double-coded digital-signal is received by the master communication device, the signal decoding is achieved, so that the identification-card singularity is recognized by the master communication device.

摘要： A vibration displacement sensing device comprises a piezoelectric substrate, an input interdigital transducer, a first output interdigital transducer, a second output interdigital transducer, and a signal analyzer. All the input-, the first output-, and the second output interdigital transducers are formed on one end surface of the piezoelectric substrate. If an input electric signal is applied to the input interdigital transducer, an elastic wave is excited in the piezoelectric substrate. A leaky component of the elastic wave is radiated effectively in the form of a longitudinal wave toward a first material located inside a second material which is in contact with the other end surface of the piezoelectric substrate and has an acoustic impedance different from that of the first material. The longitudinal wave is reflected by the first material. A reflected longitudinal wave is detected at the first output interdigital transducer as a first delayed electric signal. A non-leaky component of the elastic wave is detected at the second output interdigital transducer as a second delayed electric signal. A vibration displacement caused by the first material is sensed by the signal analyzer from a difference between the first- and second delayed electric signals.
