摘要： An ultrasonic transducer unit for use in pulse-echo ultrasonic investigation has a plurality of components including a piezoelectric ultrasonic wave transmitting element, an acoustoelectric ultrasonic wave receiving element and electrodes therefor. To provide a compact and efficient transducer, these components are bonded together in an integrated multilayer structure in which the transmitting element and receiving element are superimposed in the direction of propagation of transmitted and received ultrasonic waves. The receiving element may be a ZnO single crystal. An insulating layer isolates two components from each other.

摘要： An apparatus for transmitting and receiving ultrasonic waves has a transmitter for sending a pair of ultrasonic waves to a sample. The pair of ultrasonic waves have substantially symmetric waveforms with respect to zero sound pressure. One of the ultrasonic wave is separated from the other ultrasonic wave. An acoustoelectric, ultrasonic transducer receives the pair of ultrasonic waves affected by the sample. The acoustoelectric, ultrasonic transducer converts the pair of ultrasonic waves into a pair of electric signals accompanied by phonon-charge carrier interaction. Each of the electric signals includes an acoustoelectric signal insensitive to phase and a piezoelectric signal sensitive to phase. A processing device processes the pair of electric signals so as to remove the piezoelectric signal and obtain the acoustoelectric signal. The initial ultrasonic waves have opposite phase so that superimposition of the pair of electric signals by the processing device offsets the piezoelectric signals, thereby obtaining the acoustoelectric signals.

摘要： A solid oxide fuel cell including a flat plate-shaped solid oxide fuel cell element. The cell element is composed of an ion-conductive ceramic plate formed with ribs connected with each other in a plane, an air electrode formed on one main surface of the ion-conductive ceramic plate, and a fuel electrode formed on the other main surface of the ion-conductive ceramic plate. In producing the fuel cell, a flat plate-shaped green sheet made of an ion-conductive ceramic molding material is press contacted with a rib-forming green sheet made of a material of the same kind and having a unitary shape formed by connecting elongated portions to each other. The contacted green sheets are sintered together to form an ion-conductive ceramic plate. In an alternative, a flat plate-shaped green sheet and a rib-forming green sheet may be separately sintered and then bonded with each other to form an ion-conductive ceramic plate. The ion-conductive ceramic plate is formed with an air electrode surface and a fuel electrode on opposite main surfaces, respectively.
