The object of the present invention is to simplify the process of connecting a reservoir for charging and discharging 2 or more fluids with a pipeline for conveying said fluid and to assist the automation of this process.In the present invention, a reservoir, having, at its end face, 2 or more openings for fluids for charging and discharging 2 or more fluids respectively, is connected with pipelines by using a connecting means having flow paths for 2 or more fluids and, at its end face, 2 or more openings for fluids corresponding to each of the flow paths, and each of the respective fluids is passed, when by aligning the center of 1 of the openings for fluids of the reservoir end face with 1 of the openings for fluids of the connecting means end face and by linking said openings for fluids to each other, closed passage spaces are respectively formed which are common to the 1 or more other opening(s) for fluids of the reservoir end face and to the 1 or more corresponding other opening(s) of the connecting means end face respectively, and each fluid is passed via said spaces respectively.

A rib of an airplane wing is prevented from deforming due to a machining load when machining a rivet hole in parts where the rib and a skin are joined. With regard to a rib that provides a connection between first and second spars of the airplane wing, the rib is formed with mounting flanges secured to a skin via a rivet, a stringer through hole for a stringer to be positioned through, and first and second cutouts facing parts where the first and second spars and the skin are connected. Since reinforcing beads are formed along the mounting flanges and reinforcing flanges are formed so as to extend in the span direction from the edges of the stringer through hole and the first and second cutouts and be connected integrally to the mounting flanges, the stiffness of the rib toward a load in the vertical direction when drilling a rivet hole can be enhanced.

The present invention relates to a process for recovering and reusing a resist composition which comprises the steps of (a) collecting resin composition scattered from a spinner during application of the resist composition onto silicon wafers and otherwise no longer used and to be disposed of as waste liquid; (b) introducing the resist composition into a recovery tank; (c) introducing, while measuring the viscosity of the resist composition in the recovery tank, a solvent into the recovery tank in accordance with the measured viscosity until the resist composition shows a predetermined viscosity; (d) discontinuing the solvent supply when the viscosity of the resist composition has reached a predetermined value; (e) transferring the resist composition with the predetermined viscosity to a storage tank; and (f) taking out, whenever necessary, the resist composition from the storage tank for reuse.

In primary press forming process, a piece of blank sheet metal is draw worked so as to form a preformed work piece (Wb) provided with a bent portion (a) substantially conforming to a three dimensional contour of a leading edge of a blade to be protected and extending along a longitudinal direction, and a pair of planar portions (b and c) extending from either side of the bent portion. In a secondary press forming process, the planar portions (b and c) of the preformed work piece are stretch formed into a final shape that conforms to the corresponding profile of the blade while the bent portion (a) of the preformed work piece is clamped and protected from deformation. In other words, the bent portion of an edge protector (100) is already given with the final shape of the edge protector by the primary press forming process while the planar portions (b and c) thereof are given with the final shape by the secondary press forming process so that the two press forming processes can be executed without interfering with each other, and only two relatively simple press forming processes are required for forming the complex three dimensional shape of the edge protector.

A sticking material for hemostasis has a flexible strip-shaped base member having a high recovery property, a main surface, and side edges extending in a first longitudinal direction. An adhesive layer is disposed on the main surface of the base member. A pad is disposed on the adhesive layer and extends in a second longitudinal direction substantially transverse to the first longitudinal direction such that a space is defined between the pad and each of the side edges of the base member. The pad is of a size sufficient to exert pressure at a puncture area including punctures of both a blood vessel and a skin surface. The pad has a slight elasticity and a hardness capable of securely exerting pressure on the punctures by a shrinking action of the base member when the base member is adhered to the skin surface while being stretched to secure the pad over the punctures. A pressure plate having a width equal to or less than the width of the base member may be interposed between the base member and the pad to enable the pad to be more strongly pressed against the puncture area. The pressure plate has a size greater than the size of the pad. Hemostasis is conducted readily and effectively without the possibility of blood leaking from the puncture area.

The present invention provides a method for manufacturing a steel plate-shaped component which can increase the yield and the working efficiency. When a steel plate-shaped component (1) such as a pole parking is manufactured, a steel disk-shaped initial material (10) is vertically placed in a cavity (41) of a dice (40) of a cold forging die so that the thickness direction of the initial material (10) is perpendicular to a pressing direction. The initial material (10) is pressed through cold forging against the peripheral side portion (11) by a punch (42) while the initial thickness of the initial material (10) is maintained substantially as it is, whereby an approximate component (20) approximating the plate-shaped component (1) is obtained. Subsequently, a margin portion (25) of the approximate component (20) is removed, whereby a half-finished product (30) is obtained. The half-finished product (30) is subjected to cutting work, carburizing processing, and so on, whereby the plate-shaped component (1) is obtained.

A method of manufacturing an elliptic deep-drawn product including a first step of providing an intermediate product and a second step of providing an end product. In the first step, a rotary forming die is used to form in a blank a substantially round formed portion of a U-shaped cross-section. In the second step, the formed portion is deformed at its semicircular portion by press working to form an elliptic portion, being formed into a final shape.
