Abstract (en)
[origin: JPH01289655A] PURPOSE: To automatically measure the width of a gap and to keep it constant by providing a measuring device for measuring the width of the gap around the entire periphery of a container for accommodating workpieces and processing agents on a device for raising or lowering the casing of the container. CONSTITUTION: The dynamic pressure generated on a feed line 15 by a stationary flow is decreased as a gap 3 is expanded, and it is increased as the gap 3 is narrowed. The change of the dynamic pressure is measured by a pressure transducer 14 and is converted into an electric signal, and the electric signal is sent to an electric control device via an electric lead wire 18. A raising/ lowering device for a container casing 1 is electrically controlled by the control device, and the gap 3 around the entire periphery of a container is adjusted and is kept at the adjusted value.
