Filed: 1988-09-02
Abstract: PURPOSE:To perform correct flaw detection of a target region when the flow detection of a part beneath a welded part is performed at a 0.5 skip by setting a position where ultrasonic wave beams are transmitted and received and a gate which receives the ultrasonic wave beams from the position of the welded part of a steel pipe.

IPC: G02F1/1368
Filed: 1987-09-04
Abstract: PURPOSE:To inhibit electric discharge by a liquid crystal layer of an image signal voltage written in each picture element without using an accumulation capacity, by specifying the resistivity of a liquid crystal. CONSTITUTION:It is prevented that impurities are mixed into a liquid crystal and a specific resistance is set to >=10<11>OMEGA.cm.
