    摘要: An acoustic matching member that is incorporated into an ultrasonic transducer for transmitting and receiving ultrasonic waves, includes: at least two layers including a first layer and a second layer that have different acoustic impedance values from each other. The first layer is made of a composite material of a porous member and a filing material supported by void portions of the porous member, the second layer is made of the filling material or the porous member, and the first layer and the second layer are present in this stated order. A piezoelectric member is disposed on a side of the first layer of the acoustic matching member to form an ultrasonic transducer or an ultrasonic flowmeter. The acoustic matching member does not have independent intermediate layers between the layers, so that delamination hardly occurs and the difficulty in the designing associated with the presence of intermediate layers can be avoided.

    摘要: An ultrasonic transducer according to the present invention includes: a piezoelectric body 4 to set up ultrasonic vibrations; an acoustic matching layer 3 made of a material with a density of 50 kg/m3 to 1,000 kg/m3 and an acoustic impedance of 2.5×103 kg/m2/s to 1.0×106 kg/m2/s; a lower acoustic matching layer 9 provided between the piezoelectric body 4 and the acoustic matching layer 3; and a structure supporting member 6 that supports the lower acoustic matching layer 9 and the piezoelectric body 4 thereon and shields the piezoelectric body 4 from a fluid that propagates the ultrasonic vibrations. The ultrasonic transducer includes a protective portion, which contacts with at least a portion of a side surface of the acoustic matching layer 4. This protective portion is defined by a portion of the lower acoustic matching layer 9 and forms an integral part of the lower acoustic matching layer 9.

    摘要: A method of preparing a composite sheet unit includes arranging a plurality of sintered piezoelectric thin wires in a uniform direction on a surface of a resin layer is prepared. A plurality of the same are laminated and integrated so that the sintered piezoelectric thin wires are positioned between the resin layers. Here, a curing resin may be impregnated therein so as to form resin-impregnated-cured portions. Then, the lamination is cut in a direction crossing a lengthwise direction of the sintered piezoelectric thin wires, so that a piezocomposite is obtained. Cut surfaces may be ground. By so doing, it is possible to provide a highly reliable piezocomposite having a fine structure at low cost, and to provide an ultrasonic probe for ultrasonic diagnostic equipment, as well as ultrasonic diagnostic equipment using the same.

    摘要: A composite material (10) includes a resin (12), and first inorganic particles (11) dispersed in the resin and containing at least zirconium oxide. The composite material has a refractive index at the d line nCOMd of not less than 1.60 and an Abbe's number νCOM of not less than 20, and satisfies a relationship nCOMd≧1.8−0.005 νCOM. This composite material exhibits both a high refractive index and low dispersion in good balance, and has excellent workability. Accordingly, using this composite material makes it possible to realize a small optical component having favorable wavelength characteristics.
