Supersonic flaw detecting system
First Claim
1. A supersonic flaw detecting system having a probe that emits a supersonic wave towards an object to be inspected, scanning means for causing a relative movement between said probe and said object in two orthogonal directions, a pulser-receiver that supplys pulses to said probe and receive the supersonic wave from said object and produce an electric signal indicative thereof, signal processing means for converting said electric signal from said pulser-receiver into an image data signal for a C-scope display, oscilloscope means for conducting an A-scope display of said electric signal from said pulser-receiver, and a monitor T.V. having a screen for displaying the C-scope display of said image data signal from said signal processing means, said supersonic flaw detector further comprising:
- image memory means connected to said monitor T.V. and having addresses corresponding to the coordinate values of a coordinate system assumed on the screen of said monitor T.V.;
operation means for being operated by an operator and including position indicating means for allowing the operator to designate a desired position on the screen of said monitor T.V.; and
control means connected to said scanning means, said signal processing means, said image memory means and said operation means, and including;
first means for writing, when said probe and object are relatively moved by said scanning means, the image data carried by said image data signal from said signal processing means in the image memory means at a corresponding address thereof at each pitch determined such that the number of data pickups during the relative movement between said probe and object coincides with the number of the corresponding addresses in said image memory means, to thereby provide data for C-scope display of the image data to be produced on the screen of said monitor T.V.;
second means for allowing access to one of the addresses in said image memory means corresponding to said desired position on the screen designated by operation of said position indicating means, andthird means for computing, when said one of the addresses in said image memory means is accessed by the operation of said position indicating means, the amount of drive of said scanning means necessary for moving said probe relative to said object to a position corresponding to the designated position on the screen of the monitor T.V. from data on said pitch and said accessed address in said image memory means and driving said scanning means until said computed amount of drive is reached whereby said probe is automatically moved to and located at said position corresponding to the designated position on the screen of said monitor T.V. for allowing A-scope display at such a position to be successively followed.

Abstract
A supersonic flaw detecting system has a probe adapted to emit a supersonic wave towards an object to be inspected, a scanning device for causing a relative movement between the probe and the object in two orthogonal directions, a pulser-receiver adapted to supply pulses to the probe and receive the supersonic wave from the object and produce an electric signal indicative thereof, a signal processing device for converting the electric signal from the pulser-receiver into an image data signal for a C-scope display, an oscilloscope for conducting an A-scope display of the electric signal from the pulser-receiver, and a monitor T.V. having a screen for conducting the C-scope display of the image data signal from the signal processing device. A control unit when the probe and object are relatively moved by the scanning device, the image data carried by the image data signal from the signal processing device at a corresponding address in the image memory at each pitch which has been determined such that the number of data pickups during the relative movement between the probe and the object coincides with the number of the corresponding addresses in the image memory to thereby cause C-scope display of the image data to be effected on the screen. The is operative to compute, when the cursor is displayed on the screen by the operation device, the amount of operation of the scanning device necessary for locating the probe relative to the object at a position corresponding to the cursor on the screen and operate the scanning device by the thus computed amount to locate the probe at the corresponding position, thereby permitting A-scope display to be effected at such a position on the oscilloscope.
