Abstract: A double male connector (1) includes a first male luer (10) on one end and a second male luer (20) on the other end. The first male luer (10) and the second male luer (20) are in communication with each other. An outer circumferential surface of the first male luer (10) constitutes a first tapered surface (12) whose outer diameter decreases toward a leading end of the first male luer, and an outer circumferential surface of the second male luer (20) constitutes a second tapered surface (22) whose outer diameter decreases toward a leading end of the second male luer. A tubular portion (15) surrounds the first male luer (10). A female screw (16) is formed on an inner circumferential surface of the tubular portion (15).

Abstract: A balloon including: a pressure-receiving portion formed of an elastic material and forming an enclosed space; and a tubular portion formed integrally therewith. The balloon is configured to detect the air pressure in the pressure-receiving portion due to communication with a pressure detector through an opening end of the tubular portion. A transverse cross-section of the pressure-receiving portion orthogonal to the axial direction of the tubular portion has a flattened outer circumferential shape with an oblateness f=(A?B)/A, where A represents the length of a major axis of the outer circumferential shape and B represents the length of a minor axis thereof, being set to a range of 0.1?f?0.7 at a position at which the length A is at a maximum. The air pressure can be changed significantly and stably, and the precision of the pressure measurement can be increased.

Abstract: A process for efficiently preparing an optically active chloropropanediol derivative, especially (S)-1-benzyloxy-3-chloro-2-propanol, which has a high optical purity and is useful as an intermediate for medicines. The process comprises treating an inexpensive racemic chloropropanediol derivative with a nitroxyl compound and an oxidizing agent to convert it into a chlorohydroxyacetone derivative and then stereospecifically reducing the carbonyl group of the chlorohydroxyacetone derivative by the action of either a carbonyl-reducing enzyme having the ability to stereospecifically reduce the chlorohydroxyacetone derivative or an optically treated culture of a microorganism having the ability to yield the carbonyl-reducing enzyme. Thus, an optically active chloropropanediol derivative is prepared.
