Abstract: A heat transfer tube for a falling film type evaporator, in which water spreading characteristics, particularly the water spreading characteristics in the tube axis direction, enhancing the heat transfer ability. Three types of projections 2, 3, and 4 are formed on an external surface 1a of a heat transfer tube body 1. A respective plurality of projections 2 to 4 are arranged spirally in parallel to one another, forming projection groups 2a to 4a. The number of each projection group 2 to 4 is one. Pitches P2 to P4 for the projections 2 to 4 are in the range of 0.35 mm≦P4<P3<P2≦5.95 mm. Heights h2 to h4 of the projections 2 to 4 are in the range of 0.1 mm≦h4<h3<h2≦0.5 mm. Pitches for the projection groups 2a to 4a is in the range of 0.72 to 1.12 mm.

Abstract: A outerwear comprising of a front body cloth, a rear body cloth, right and left flank cloths having a predetermined width and right and left sleeve cloths, one edge of each right and left flank cloth is sewn to the front body cloth and the other edge of each right and left flank cloth is sewn to the rear body cloth such that each sewing line does not coincide with right and left flank lines, each of the right and left flank cloth is extended to the under-sleeve part sewn to the sleeve cloth; an elongation percentage of each of the front body cloth and the rear body cloth is set high in a horizontal direction thereof.

Abstract: A cap heat-sealing apparatus for containers comprises a stationary pressing member (18), and movable pressing members (19) arranged around the stationary pressing member (18) and identical in number to the number of corners of a container opening fitting portion (8) of a polygonal cap (5) formed at its periphery for heat sealing. The stationary pressing member (18) has an outer periphery shaped in conformity with the shape of the inner periphery of the fitting portion (8). Each of the movable pressing members (19) is movable toward or away from the stationary pressing member (18) in a horizontal direction through the center of the stationary pressing member (18) and the corner thereof opposed to the movable pressing member (19).

Abstract: Disclosed herein is a magnetic recording medium, (1) in which a magnetic layer is formed by coating a magnetic paint containing a magnetic powder and a binder as its main components on a non-magnetic base material; (2) which is featured by containing as said binder a polymer having an alkenyl phenol as one of the components of the polymer; and (3) which has markedly improved effects in the dispersibility of the magnetic powder in said medium and in the abrasion resistance and flexibility of the magnetic layer.
