Abstract: The object of the present invention is to provide a polynucleotide which can be inserted into an expression vector and can enhance the transcriptional activity of a predetermined promoter under heart failure. The object is achieved by an enhancer polynucleotide comprising a polynucleotide consisting of a sequence having 80% or more identity with a sequence represented by SEQ ID NO: 1, or a polynucleotide consisting of a sequence having 80% or more identity with a sequence represented by SEQ ID NO: 2, wherein the enhancer polynucleotide responds to heart failure (where the enhancer polynucleotide excludes a polynucleotide having the same sequence as a sequence represented by SEQ ID NO: 13 and a polynucleotide having the same sequence as a sequence represented by SEQ ID NO: 12).

Abstract: A pinion shaft (7) formed using a non-refined steel as a material comprises a shaft section (71, 72) and a pinion teeth forming section (70) connecting with the shaft section (71, 72). The pinion teeth forming section (70) comprises pinion teeth (7a) and a tooth bottom (7b). The pinion teeth forming section (70) and the shaft section (71, 72) are provided with a hardened layer (80) that has been subjected to induction hardening and tempering. The steel contains 0.45 to 0.55% by mass of C, 0.10 to 0.50% by mass of Si, 0.15 to 0.25% by mass of Mo, and 0.0005 to 0.005% by mass of B. The surface hardnesses of the pinion teeth forming section (70) and the shaft section (71, 72) are 650 to 760 HV in terms of Vickers hardness.

Abstract: A CO.sub.2 deep sea throw-away system includes a floating offshore base (2), receiving liquefied CO.sub.2 carried by a liquefied CO.sub.2 carrier (1). The base has a throwing pipe (3) and a throwing pipe outlet (4) to deliver the liquified CO.sub.2 in an enclosing bag (11) in the sea at a depth where a liquid phase state of the liquified CO is maintained. An unmanned submersible working boat (10) is provided and has a plurality of capsules (26) mounted thereon. Each capsule contains an enclosing bag (11) to enclose the liquified CO.sub.2. The boat transports the capsules into the sea at a depth where a liquid phase state of the liquified CO.sub.2 is maintained and operates to enclose the liquified CO.sub.2 in the enclosing bags (11). The liquified CO.sub.2 in the enclosing bag (11) and the capsule (26) are then released so as to fall onto the sea bottom. Also, a control base (9) is provided on the offshore sea to control the unmanned submersible working boat (10).

Abstract: The present invention relates to a digitizing control apparatus for outputting smooth data along an original tracing path by correcting digitized data. Coordinate data of a digitized model surface is calculated by adding coordinate data commanding a tracing path on a model surface to the measuring displacements at trace measuring points of a sensor. Coordinate data of the respective trace measuring points is corrected to digitized data approximated by a new coordinate point on a tracing plane containing the tracing path. Corrected coordinate data is output as smooth digitizing data along the original trace path.

Abstract: A liquefied carbonated gas abyssal casting apparatus prevents freezing at an outlet of a casting tube and flotation of cast carbonated gas. The liquefied carbonated gas is fed from a reservoir to a single casting tube and discharged to the abyss through an inner tube of a double casting tube from a lower end of the single casting tube. A heat medium fluid is recirculated between the inner tube and an outer tube of the double casting tube. The liquefied carbonated gas which flows through the inner tube is heated to an abyssal temperature of from -1.degree. to 5.degree. C.

Abstract: A tracing operation by designating a region is performed after a wire limit. Tracing line segments (2a, 2b, 2c) parallel to the wire limit (1)are found connecting a plurality of points. The tracing operation is performed by moving a stylus on a path along the tracing line segments (2a, 2b, 2c), whereby a tracing region determined by a complex wire limit can be accurately traced.

Abstract: A contour profiling machine for the purposes of shortening the period of time for rough machining and forming a smooth machined surface in the execution of machining wherein the outer part or inner part of a workpiece is cut away along the contour of a model (MDL). The contour profiling machine according to the present invention includes a limit setting circuit for setting a limit as to one axis of a tracer head (TC), and for setting limits parallel to and limits orthogonal to a traveling direction within a movement plane which is determined by the first-mentioned limit. A polarity discrimination circuit discriminates the polarities of the limits set relative to the direction of movement of the tracer head (TC). A clamping ciruit clamps contour profiling within a range which is defined by the set limits.
