A pouch exterior material that enables an electrode assembly to be easily mounted on an accommodating portion at a proper position, having an integrated shape and including an inserting portion provided at a center of the pouch exterior material and having a width equal to a thickness of the electrode assembly, accommodating portions provided symmetrically at two sides of the inserting portion and gradually deepening from a portion corresponding to a width center of the electrode assembly towards a portion corresponding to an edge of the electrode assembly, and a triangular stepped portion provided at two ends of the inserting portion and having a depth gradually decreasing towards an end.

In the vicinity of an opening end of a first liner constituent member and a second liner constituent member made of a resin material, a flange portion is formed. After end surfaces of the opening end are abutted and joined to each other, the flange portion is removed in such a way that a part of a bottom portion remains. The remaining amount of protrusion is set such that the joint strength of a joint portion is not less than the tensile strength of the resin material or not less than the cohesion failure strength of the joint portion.

A unit (10) for the regulation or control of a fluid pressure, having at least one housing section (13, 14) and a switching film (22) connected to the at least one housing section (13, 14) for switching at pressure differentials relative to an ambient pressure acting on the switching film (22), and for the regulation, release or blocking of a flow of the fluid between an inlet (28) and a discharge (30) for the fluid. The switching film (22) is made out of a polymer material having fluorine and carbon, in particular a thermoplastic having fluorine and carbon. In this arrangement, a hole cross-section (40) of the at least one housing section (13, 14) is closed off by the switching film (22).

A stretch-blown plastic container, includes a container body which encloses a filling volume with a container bottom; a container neck which adjoins an opposite end of the container body, having a container opening and an integrated handle region, the handle region being hollow and joined to the filling volume which is enclosed by the container body; and between the handle region and the container body, a through opening recessed and bordered over its entire periphery by wall parts of the container body and of the handle region which have been welded to one another.

An axial alignment structure for a fluid pressure pump (100) includes: a first housing made of a resin; and a second housing made of a resin, in which a housing is configured in a state where the first housing and the second housing are joined to each other by thermal welding at a welding position, and a pump rotor is accommodated in the housing, and the first housing and the second housing have an axial alignment mechanism that axially aligns the first housing and the second housing such that axes of the first and second housings coincide with each other at the time of joining of the first housing and the second housing to each other by the thermal welding.

A rotation speed sensor, configured to detect a rotation speed of a rotating body, is composed of a cable composed of an electric wire including a conductor wire, and a sheath provided over the electric wire, a circuit substrate mounted with an integrated circuit thereon and connected to the conductor wire being exposed from the cable, and a housing including a first housing, which is configured to hold the circuit substrate therein, and a second housing, which is configured to hold the cable therein, with the first housing being welded to the second housing, and with the second housing being welded to a surface of the sheath of the cable.

According to one embodiment a plug-in connector is provided that includes a female connector and a male connector. The female connector includes a head configured for being connected to the male connector and a body fixed to the head which is configured for being attached to a pipe/hose. A contact area including a line of contact communicated with the inside of the female connector is defined between the head and the body. The plug-in connector also includes a sealing gasket configured for assuring leak-tightness between the female connector and the male connector, the line of contact being arranged in a previous axial position with respect to at least part of the sealing gasket in the direction of insertion of the male connector into the female connector, such that the sealing gasket itself also assures the leak-tightness in the line of contact.

A control rod for incorporation into a composite assembly with at least a first composite preform, a second composite preform, and a cured resin includes a shaft defining an axis, wherein the shaft is disposable within an aperture in the composite assembly, and a plurality of threads disposed on at least a portion of the shaft. The shaft is made from, among other materials, a thermoplastic material. The threads define a thread pitch that encompasses more than one individual fiber layer forming at least one of the first composite layer and the second composite layer.

A method is disclosed for manufacturing connecting members for connecting an aircraft wing to a center wing box, using preforms. The method involves a step of manufacturing at least one preform made of composite material forming the connecting member, and a step of assembling the preform or preforms by heat treatment to form the connecting member. The manufacturing method makes it possible, simply and quickly, to manufacture a connecting member that contributes to the connection between a center wing box of an aircraft and a wing of the aircraft.

A plastic tank is comprised of two parts, a base and a top, that are permanently joined to each other by welding at a circumferential joint formed by two mating flanges of the parts. Fusion weld elements are captured on the faying surfaces of the flanges of the assembled parts, and the elements melted by internal heating of metal portions of the elements. Before heating of the elements, the flanges are gripped by a clamp which applies a resilient force which, during welding, causes the flanges to move toward each other and thereby a good weld joint is formed.
