The adhesive bonding and sealing by application of adhesive material and sealing material at corresponding seams and joints, wherein the adhesive material is arranged to rest directly, at least in part, on the sealing material.

A method for manufacturing a check valve unit as a liquid flow path member, in which the liquid flow path member includes, in a flow path direction of ink, a first flow path member constituting one side of a flow path, a second flow path member constituting another side of the flow path, and a check valve including a valve body configured to stop a backflow of the ink in the flow path and a check valve holding member configured to hold the valve body, the method includes a welding step for welding the first flow path member or the second flow path member, and the check valve holding member together, and also welding the first flow path member and the second flow path member together.

Various components, such as radio frequency (RF) or thermal reflectors, may be constructed from joining of pre-formed tape. For reflectors, this process may reduce the number of ribs, only require partial ribs, or eliminate the use of ribs altogether. To build such a reflector, a spool of tape, a joining tractor, and a foundation ring may be employed.

Provided is a laser welded body which can be integrated through a laser-welding step without undergoing complicated steps even through use of the same or difference resin members each other, which has excellent welding strength between the resin members, which maintains the characteristics of a resin contained in the resin member and which exhibits the high welding strength by improving meltability of the resin members yet under a laser-welding condition of a medium and high scan speed.

A laser welded body comprises a resin member(s) which contains a thermoplastic resin and nigrosine sulfate having a sulfate ion concentration of 0.3 to 5.0% by mass and has an absorbance a of 0.09 to 0.9, an adjoined part where the resin member(s) is overlapped and/or butted, and at least a part of the adjoined part is laser-welded.

The present invention relates to a method for manufacturing a pressurizable cylindrical vessel for use in a pressure control system for maintaining a constant predetermined pressure in a fluid container configured to dispense when in use a fluid contained in said fluid container at said constant predetermined pressure, characterized in that the manufacturing is by injection moulding. The invention also relates to a method for assembling a pressurizable fluid container configured to dispense when in use a fluid contained in said container at a constant predetermined pressure. In addition, the invention relates to a pressurizable cylindrical vessel, a pressurizable unit, a pressure control system, a bottom plate and a dispenser; as well as their methods of manufacturing. In a final aspect the invention relates to uses of said parts in a bag-on-valve type packaging or metal can type packaging.

A composite vehicle driveshaft assembly includes a composite tube and a yoke bonded to one of the ends of the tube. The yoke has an inner sleeve that is concentrically received in the end of the tube. The sleeve has an outer peripheral surface that faces the inner peripheral surface of the tube with a cavity formed therebetween. An adhesive injection passage is formed in the yoke and extends at an acute angle from an inlet that is formed in an axial surface of the yoke to an outlet that is formed in the outer peripheral surface of the sleeve and that opens into the cavity. Also disclosed is a method of bonding a yoke of such a driveshaft assembly to a composite tube.

A blade shell part for a wind turbine blade and a wind turbine blade are disclosed. The blade shell part is made of a composite structure comprising a reinforcement material embedded in a polymer matrix, the blade shell part extending from a tip end to a root end, wherein the blade shell part comprises: a blade shell body with a leading edge and a trailing edge, and a first glue flange extending from the leading edge and having a first glue flange edge and a first glue surface with a first width, wherein the first glue flange is provided with one or more spacer elements. Further, a method of manufacturing a wind turbine blade is described.

The present invention relates to a method for producing a container which consists of a thermoplastic at least to some extent and comprises at least a first compartment element and at least a second compartment element joined to the first compartment element in a joining region by thermoplastic welding. The invention also relates to a plastic container which can be, and preferably is, produced according to said method.

A pipe coupler has: an axis; and a body portion surrounding the axis. A circumferentially segmented collar extends from a first axial end of the body portion and has an inner diameter surface and an outer diameter surface. A plurality of fingers project from a second axial end of the body portion, axially opposite the first end and have inward radial projections.
