Title: Ultrasonic inspection equipment
Inventor: MIYATA TORU
IPC: G01N29/38
Filed: 1991-12-06
Abstract: PURPOSE:To allow high speed movement of a probe by inputting a gate delay time and a gate width thereby automatically setting the period of pulse train repetition frequency (PRF) and eliminating erroneous recognition between transmission pulse and echo thereof. CONSTITUTION:A gate delay time and a gate width, defining a gate timing, are inputted on an operating panel 8 to a gate time input program 6a in a memory 6 through an interface 7. The gate delay time and the gate width are then set in a gate circuit 2c using a gate setting program 6b. Furthermore, gate delay time + gate width + talpha is set, as the period of PRF, in a pulser 2a through an interface 4 using a PRF calculating/setting program 6c. In this regard, talpha represents a plus alpha time necessary and sufficient for separating between the gate and next transmission wave. Since the period of PRF does not shorter than the end point of gate, echo from a specimen follows after the transmission wave and thereby error is prevented.
