Abstract: A program development support device that manages program components on a project basis includes: a program component creating unit that adds a name to each of the program components; and a program component managing unit that identifies identity between a plurality of the program components when the program components are combined, based on a program component name and specification information, the program component name being the name added by a user to corresponding one of the program components by using the program component creating unit, the specification information being creation information specified by the user among a plurality of types of the creation information that is information relating to creation of the corresponding one program component.

Abstract: A piston ring for use at temperatures above 350° F. at pressures greater than or equal to about 2000 psi, comprising a gap having a gap width about 1.4 to about 2.0 times greater than a thickness of the piston ring; a height about 4.5 to about 6.4 times larger than the thickness, and a leading edge characterized by an arc having a radius of curvature of less than or equal to about 4 times the height. The piston ring may be formed of a material comprising cobalt, chromium, tungsten, and carbon. A gas compressor and method of sealing a piston using the above piston ring is also provided for.

Abstract: In a crushable plastic bottle, a plurality of foldable creases are formed on a wall surface of a body of the plastic bottle so as to in a longitudinal direction thereof in parallel. The foldable creases are formed so that wide and narrow creases are arranged alternately so as to form inequilateral lambda's (&Lgr;'s). When the foldable creases are folded, the narrow creased are roughly turned over in such a way that each inner surface of the narrow crease is brought into contact with the inner surface of each outward adjacent wide crease. Thus, with each narrow crease sandwiched between the two adjacent wide creases, the wide crease are overlapped with each other and fixed in shape as they are.

Abstract: A beverage can that is capable of crushing easily in the axial direction is provided. The beverage can is designed to contain a beverage and has a roughly circular cylindrical shape with, at a prescribed portion on one end surface thereof, an operational portion for forming a beverage-input port. A side wall of the can has a bellows-like structure provided with score lines.

Abstract: The present invention is a device that can obtain fresh water from fog. The fog water collecting device comprises a vertical shaft, windmill elements for producing rotational force from wind, a cylindrical rotating structure supported so as to rotate about the vertical shaft, a water collecting vessel secured at the bottom of this rotating structure, a plurality of flexible rods one end of each is fixed at the upper portion of the rotating structure and the other end of each is directed toward the water collecting vessel and, a receiving conduit for obtaining water collected in the water collecting vessel. When the rotating structure turns from fog containing wind, water droplets sequentially adhere and accumulate on the flexible rods, then collect in the water collecting vessel, and are subsequently directed toward an external destination via the conduit.

Abstract: The efficiency of silver recovery from photographic processing solutions is improved by the installation of a silver recovery water tank between the fix or blix tank and the wash water tank, which is provided with a mechanism for maintaining the silver concentration of said recovery tank at a substantially constant value, said mechanism comprising a detecting means for measuring the amount of the photographic material treated by the processing line involved and a means to supply water thereto operatable by signal from said detecting means.
