Abstract: PROBLEM TO BE SOLVED: To easily obtain a high purity alkali metallic cyanate in a state suitable for use as a starting material for producing a cyanuric acid derivative by allowing an alkali metallic carbonate to react with urea in an amide solvent to form a reaction product suspended in the solvent. SOLUTION: An alkali metallic carbonate [M2CO3 (M is Na, K or Li)] is allowed to react with urea [(NH2)2CO] in an amide solvent to obtain the objective alkali metallic cyanate (MOCN) suspended in the solvent. The amide solvent is preferably dimethylformamide and the amount of the solvent used is usually about 0.5-10 times (weight) the amount of the urea. The reaction is carried out by a batch system under atmospheric pressure or elevated pressure at about 100-200 deg.C for >=1 hr. When the suspended alkali metallic cyanate is allowed to react with an aliphatic halogenated compound such as a halogenated allyl, a halogenated 2-methylallyl or a propyl halide, the objective high purity cyanuric acid derivative is efficiently obtained in a high yield.

Abstract: PURPOSE:To enable highly accurate flaw detection with uniform sensitivity over the entire flaw detecting surface, by making a probe movable vertical to an object to be inspected follow up changes in the water distance. CONSTITUTION:A water distance measuring circuit 11 measures a distance to an object 2 to be inspected by an ultrasonic video signal (c) of a flaw detector (b) and set reference data to keep water distance constant on a compare circuit 12 beforehand.
