    摘要: Provided is a 2-dimensional virtual array probe for 3-dimensional ultrasonic imaging. The probe includes: an ultrasonic transducer; a metallic probe body including an ultrasonic wave emission surface in which a plurality of wave-guides are arranged in 2-dimensional array and a ⅛ sphere-shaped recess for irregularly reflecting ultrasonic wave emitted from the ultrasonic transducer in an inside thereof; a piezoelectric sheet arranged on the ultrasonic wave emission surface to make contact with an object to be inspected and configured to pass the ultrasonic waves emitted from the probe toward the object to be inspected and output a signal by detecting the ultrasonic waves reflected from the object to be detected; and a control unit configured to control the ultrasonic transducer so that the plurality of wave-guides sequentially generate ultrasonic wave.

    摘要: Disclosed therein is a valve control apparatus for a tank lorry. The valve control apparatus for the tank lorry includes a first control valve for opening and closing the oil feed valve by supplying compressed air to the oil feed valve or discharging the supplied compressed air to the outside, a second control valve for actuating the first control valve by the user's manual manipulation, an automatic closing valve for actuating the first control valve, a third control valve for selecting an operation of the automatic closing valve, and a pneumatic circuit for realizing functions of the control valves, wherein the control valves are general direction conversion valves for converting a flow of the compressed air and can be controlled on the road. So, a user can carry out a loading work in more convenient and safe when the user loads oil articles or chemicals on a storage tank mounted on the tank lorry.
