    摘要： An ultrasonic sector-scan probe comprises at least an array having a plurality of ultrasonic transducer segments, a window for transmitting and receiving ultrasonic waves and an ultrasonic wave propagation medium filled in a front space between the array and the window. A group of the ultrasonic transducer segments are selectively driven as an aperture and ultrasonic waves emitted therefrom are converged into a beam for transmission and reception. By partly or entirely changing the segments in the group with the ones outside the group the scan line is shifted to a new angle, and a member under test contacted with the window on the outside thereof is sector-scanned by the ultrasonic beam. The array is arranged so that scanning lines of the groups intersect at one point in the window or in its vicinity for sector scan. An acoustic lens is provided in the window or in its vicinity so that the ultrasonic beam may be converged over the measuring depth range of the member under test with or without phase control of the segments in the group. Furthermore, the array is arranged multidimensionally or in plural linear arrays so that the scanning lines of the groups intersect substantially at one point in the window or in its vicinity for sector scan, thereby performing sector scan of at least two sections and/or three-dimensional sector scan.

And an acoustic lens is provided in the window or in its vicinity so that the ultrasonic beam may be converged almost over the measuring depth range of the member under test with/without phase control of the segments in the group. Furthermore, the array is arranged multidimensionally or in plural linear arrays so that the scanning lines of the groups intersect substantially at one point in the window or in its vicinity for sector scan, thereby performing sector scan of at least two sections and/or three-dimensional sector scan.

    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： There is provided an ultrasonic printer in which convergent ultrasounds are radiated to emit an ink near a convergent point of the convergent ultrasounds in the form of an ink droplet and deposit the ink droplet on a recording medium such as a paper sheet, thereby performing a recording on the recording medium with multiple ink dots, with higher resolution. The ultrasonic printer has a plurality of ultrasonic transducers which transmit phase-controlled ultrasonic waves to form an convergent ultrasonic acoustic beam.

    摘要： Ultrasonic transducer having a plurality of piezoelectric elements arranged in a matrix, and a method for fabricating them. L shaped printed wiring boards are respectively bonded to each arrays of piezoelectric elements arranged in azimuthal direction. The bonding points of the L shaped printed wiring board to respective piezoelectric element are located at edge portion of respective back electrode. The other branch of L shaped printed wiring boards are stretched vertically to the surface of the piezoelectric elements matrix. A backing plate is formed by molding on the back side of the piezoelectric elements matrix leaving the top of the L shaped printed wiring board protruded from the molded surface of the molded backing plate. Such configuration prevents the reflection from the wiring plate of the piezoelectric element. A flexible printed wiring board is provided with wiring pattern having bonding areas positioned corresponding to the matrix of piezoelectric elements. So, the bonding of the printed wiring board to each of the piezoelectric element is easy. After the bonding, the printed wiring board is cut and bent vertically to the matrix surface to form the L shape. The matrix of piezoelectric elements may be cut out from a large size piezoelectric element before the molding of the backing plate or after its molding.

    摘要： An ultrasonic diagnostic apparatus including ultrasonic transducers. The ultrasonic diagnostic apparatus performs calculations for respective ultrasonic transducers to determine at which focal position a signal having just been received by the transducers is reflected in accordance with a lapse of time from a time when ultrasonic waves are transmitted. A delay time of respective received signals obtained from the transducers are determined in accordance with the results of the calculations. According to the present invention, control data which determines the delay time is stored in a first stored apparatus, compensation data which compensates the control data is stored in a second storage apparatus. The control data and compensation data read out respectively from these first and second storage apparatuses are added to one another, and the delay time for transmission and reception is determined according to the sum of the control data and compensation data.
