    摘要： An ultrasonic imaging apparatus includes an ultrasonic transducer for outputting an ultrasonic beam and converting the echo of the ultrasonic beam into an echo signal, a transmitter section for supplying a drive signal to the ultrasonic transducer, a receiver section for receiving the echo signal output from the ultrasonic transducer and converting the echo signal into an image signal, and a coaxial cable for coupling the ultrasonic transducer to the transmitter and receiver sections. The ultrasonic transducer is constituted by a two-layer ultrasonic transducer having an impedance smaller than an impedance of the coaxial cable.

    摘要： A driving circuit controls a time for applying a drive signal to a piezoelectric element so as to bring a control in the number of ink droplets squirted from a liquid surface of liquid ink according to a gray scale level of an image to be printed on a printed object. According to application of the drive signal, acoustic waves emitted from a piezoelectric element array are focused in a main scanning direction, made incident to an acoustic lens via an acoustic matching layer, further focused in a direction orthogonal to the main scanning direction and focused in a vicinity of the liquid surface in a point form. In the vicinity of the liquid surface, an ink liquid mound is formed by means of pressure (discharging pressure) generated by the focused acoustic waves and then from a tip of the ink liquid mound an ink droplet according to the application time is squirted. The squirted ink droplet is ejected and stuck to the printed object. By performing main and subscanning to the printed object, a two-dimensional image is printed thereon.

    摘要： An ultrasonic diagnosing system includes a probe having an vibrator made of a plurality of spaced piezoelectric; material elements arranged in a matrix, first electrodes arranged on one surface of the vibrator in an array of rows parallel to each other, and second electrodes arranged on another surface of the vibrator in an array of rows parallel to each other and orthogonally to the first electrodes.Particularly, the piezoelectric material elements are spaced by spacer segments arranged between the electrode rows and formed from a high molecular weight material with less acoustic impedance than the piezoelectric material, a Shore hardness D50 or more (JIS) and a thickness of about 1/10 to 1/2 of the piezoelectric elements. The ultrasonic diagnosing system uses a phased array technique to provide tomograms at mutually orthogonal and spatially close positions with sufficient sensitivity.
