    • A method for examining a layer having defects and in particular the thickness of a machining damaged layer on a surface of a sample by means of a focused ultrasound beam and a device for realizing the method are disclosed, in which a focused ultrasound beam is generated and ultrasound reflected by the sample is detected. Curves (called V(z) curves) representing the relation of the distance between a transducer detecting the reflected ultrasound and the sample versus the detection output are traced while varying the distance and this measurement is repeated while varying the frequency of the focused ultrasound beam. The propagation velocity of surface acoustic wave in the sample is calculated on the basis of the period in each of the plurality of V(z) curves and a frequency dependence characteristic curve for the propagation velocity is obtained. The thickness of the machining damaged layer in the surface portion of the sample is evaluated from inflection points in the frequency dependence characteristic curve.

    • An ultrasonic diagnostic apparatus is disclosed for transmitting ultrasonic waves and receiving echo signals. The apparatus includes an ultrasonic probe having transducers whose sensitivity can be controlled in accordance with bias voltage. Echo signals output from the ultrasonic probe are amplified so that an image can be constructed according to the amplified echo signals and displayed. A probe gain control device is used for controlling the bias voltage in accordance with the elapsed time from receiving the echo and matching the intensity of the echo signal output from the ultrasonic probe with the input range of a preamplifier. During a reception period while a strong echo signal is received from a superficial portion of body surface of an examinee, the reception sensitivity of the ultrasonic probe is controlled so that the echo signal level input to the preamplifier will not exceed the input range of the preamplifier.
