摘要： An ultrasonic piezoelectric transducer and a method for measuring and/or monitoring the thickness of a wear member, in-situ, and the amount of wear that has occurred thereto, is disclosed. The transducer includes a sleeve which is received in a blind bore provided in the wear member, a piezoelectric element positioned within the blind bore, and an aligning spacer means interposed between the end of the sleeve and the piezoelectric element. By the application of appropriate voltage pulses to the piezoelectric element, the wall thickness between the bottom of the blind bore and the inner surface of the wear member can be measured.

摘要： The present invention relates to a system and method for detection of contraband such as concealed explosives, drugs, smuggled goods, etc., through the use of an acoustic frequency detector having a crystalline transducer module and mass comparator. The present invention can be employed in a non-destructive manner for the mobile and stationary inspection of object such as luggage, person, containers, etc., through a combination of computer-aided electron counting and mass analysis techniques combined with a crystalline and oil enhanced transducer that, upon return of a system-generated acoustic signal, are used to screen and confirm explosive threats and/or other contraband.

摘要： A piezoelectric element has a diaphragm, a first electrode on the diaphragm, a piezoelectric layer on the first electrode, and a second electrode on the piezoelectric layer. The piezoelectric layer is a stack of multiple piezoelectric films and is made of a perovskite composite oxide containing lead, zirconium, and titanium and represented by the general formula ABO3, with the molar ratio of the A-site to the B-site (A/B) in the perovskite composite oxide being 1.14 or more and 1.22 or less. In current-time curve measurement, the activation energy calculated from relaxation current using an Arrhenius plot is 0.6 [eV] or less. The relaxation current is the amount of current at the time at which a downward trend in current turns upward.
