  • Ultrasonic dimension measuring apparatus
    Patent number: 4800757
    Abstract: An apparatus for measuring a dimension of an object by using ultrasonic waves includes: a pair of probes spaced apart one of the probes being to face a top surface of the object and the other of the probes being to face a bottom surface of the object; control for choosing what to be currently measured from three kinds of travelling periods of time which ultrasonic pulses take: to propagate between the probes; to travel between the top surface of the object and the probe facing the top surface; and to travel between the bottom surface of the object and the other probe facing the bottom surface and apparatus responsive to the transmission and reception signals for evaluating the three kinds of travelling periods of time and for calculating the dimension of the object from the evaluated travelling periods, whereby the probes can be out of touch with the surfaces of the object.
