摘要： A plurality of rectangular piezo-electric ultrasonic sector transducers are aligned to form an array, and each transducer has first and second electrodes on its radiating surface. The first electrode is located on a center line of the sector transducer's length, and has a first length in the longitudinal direction and a first width along the center line. Two of the second electrodes are arranged outside the first electrode, symmetrical to the center line. The two second electrodes have a second length in the longitudinal direction longer than the first length, and have a second width which is almost the same as the first width, along a line near the center line. Thus, diamond-shaped electrodes excellent for providing a beam narrow in the longitudinal direction can be employed as the first electrode, and the combination of the first and second electrodes can be connected to each other. The first electrode is designed to provide an ultrasonic beam narrow at a distance shorter than a focal length of an acoustic lens provided on the transducers, and the combination of the first and second electrodes is used to provide an ultrasonic beam narrow in another distance substantially longer than the focal length, so that a sharp beam can be delivered for both the short distance and the long distance.

摘要： An ultrasonic probe includes a housing, a piezoelectric element provided in the housing, the piezoelectric element emitting an ultrasonic beam, and a refracting member rotatably provided in the housing. The refracting member has a first surface opposite to the piezoelectric element and a second surface at which the ultrasonic beam emitted from the piezoelectric element and passing through the first surface is deflected in a state where a deflection angle between an axis perpendicular to a surface of the piezoelectric element and a deflected ultrasonic beam changes as the refracting member rotates.

摘要： An acoustic coupler, combined with an ultrasound probe, is made of a gel a part of which is hardened for providing holding means for holding the probe for lifting up the probe with the coupler and another part of which is used to form an acoustically transparent path between the probe and a surface of an object to be acoustically inspected. Poly vinyl alcohol (PVA) is a typical material for the gel, and the coupler is fabricated by molding a PVA solution by partially increasing concentration of PVA and/or a repeating frequency of refrigerating and thawing the PVA solution, compared with those for the transparent path, in a molding process of the coupler.

摘要： A method of fabricating an ultrasonic coupler to a specified configuration such that the ultrasonic coupler is fabricated by freezing and defrosting an aqueous solution containing a polymer. A surface of the fabricated ultrasonic coupler is made to be smooth. The ultrasonic coupler is fabricated using an ultrasonic coupler fabricating die including members each made of silicone rubber which varies in compliance with the expansion and the contraction of the aqueous solution. To fabricate the ultrasonic coupler, the aqueous solution containing a polyvinyl alcohol (PVA) is poured into the die. Then, the die is subjected to the process of cooling to below the freezing point and the process of recovery to room temperature so as to progress a bridging of the PVA, thereby progressing a gelling of the aqueous solution.
