IPC: G01N33/52
Filed: 1994-08-11
Abstract: PURPOSE:To provide a new water-soluble compound useful as a reagent for quantitative analysis of a dehydrogenase and a substrate. CONSTITUTION:This compound is expressed by formula I (R<1> is H or methoxy; R<2> is H, carboxyl or sulfonic acid). The compound is synthesized by oxidizing formazan of formula II with an oxidizing agent such as butyl nitrite in an alcohol solvent. Quantitative analysis of the concentration of a dehydrogenase is carried out by using this compound of formula I, reacting the dehydrogenase therewith and measuring the absorbance of the produced formazan. This compound improves water solubility of formazan, prevents precipitation onto a measuring equipment, has the maximum absorption band in a long wavelength region of 510 to 550nm and, therefore, is not interfered by a biological component such as bilirubin or hemoglobin. Accordingly, this compound is useful in clinical examination since it enables measurement by an autoanalyzer.

IPC: B22D11/08
Filed: 1994-08-11
Abstract: PURPOSE:To simplify the work to charge a dummy bar for continuous casting of a slab in a mold. CONSTITUTION:When a sealing material 1 is preliminarily fitted to an outer circumferential end part of a dummy bar 2 and the dummy bar 2 is charged from the upper part into a mold 3 where the clearance between the longer side and the shorter side is preliminarily set wider than that during the casting, a mechanism 6 to adjust the clearance between the dummy bar 2 and the mold 3 is set on one or more parts on the side of the head of the dummy bar at the lower part of the sealing material 1. A first mechanism of this clearance adjusting device 6 is of the inversely tapered shaped where the thickness of the upper part is increased while the thickness of the lower part is reduced, and is a projection made of the shrinkable material. The clearance adjusting device is a roller--shaped projection made of shrinkable material, and a spring mechanism is used as a supporting mechanism of this projection. This reduces the working load to charge the dummy bar for continuous casting the slab into the mold, and reduces the working time for preparing the casting work.
