Provided herein is a spar cap having a profile for guiding and receiving a shear web for wind turbine blade. Particularly, the present disclosure provides a pultruded spar cap having a bond gap feature to maintain a uniform space for distribution of bonding paste between the spar cap and shear web. Also, the spar cap is formed with locating features which guide and receive placement of the shear web.

Provided is a welding joining method for joining end portions of first and second pipes made of polyamide resin by bonding the end portions to each other by pressure in a molten state. The welding joining method includes: a placing step of placing an infrared radiation lamp between the first and second pipes placed to face each other at an interval; a heating and melting step of heating and melting the end portions of the first and second pipes by emitting infrared; and a pressure bonding step of cooling down the molten end portions in a state where the molten end portions are bonded to each other by pressure.

In some examples, manufacturing techniques for implantable medical devices are described. An example method may including positioning a metal housing component adjacent to a polymer housing component so that there is an interface between the metal housing component and the polymer housing component; and forming a seal at the interface between the metal housing component and the polymer housing component to join the metal housing component and the polymer housing component, wherein the joined metal housing component and the polymer housing component form at least a portion of housing for the implantable medical device, wherein the housing of the implantable medical device contains electronic circuitry.

A new method for fully automatically manufacturing a fluid container with a pressure unit is described, which pressure unit is mounted in a fluid container. In a station the high-pressure container of the pressure unit is mounted with the closure and the bottom part and is clamped at the upper and lower ends by clamping means and is rotated by rotating means associated with the clamping means. The rotating pressure unit is welded by first laser means and by second laser means, whereas the laser beam of the first laser means being directed to a first joint area of the bottom part of the pressure unit with the container, and the laser beam of the second laser means being directed to a second joint area of the bottom part of the pressure unit with the container, which first and second joint area are separated at a distance to each other.

A bonding system includes a supporting jig having a mounting surface on bonding substrates which are mounted, a bonding device that sandwiches and welds the bonding substrates between itself and the mounting surface, an articulated robot to which the bonding device is attached, and a control unit that controls the articulated robot and the bonding device.

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.

A wind turbine blade and associated method of manufacture is described. The blade comprises an outer shell formed of first and second half shells joined together. A shear web is arranged inside the outer shell. The shear web has a web panel disposed between first and second longitudinally-extending mounting flanges. The shear web is bonded to inner surfaces of the respective half shells via a first adhesive bond line between the first mounting flange and the inner surface of the first half shell and a second adhesive bond line between the second mounting flange and the inner surface of the second half shell. One or more bond spacers are provided in the second bond line, and optionally in the first bond line. The bond spacers are compressed between a shear web mounting flange and an inner surface of a half shell and are plastically deformed. The method of making the shear web involves compressing and the one or bond spacers in the bond line(s) such that they undergo plastic deformation. This results in high quality bond lines.

This heat-caulking device is inserted into one or more holes penetrating a main plate having a substantially conical hollow portion, whereby one or more bosses of a blade protruding from an inner peripheral surface of the main plate toward the hollow portion are melted so as to join the main plate and the blade. A heat chip of the heat-caulking device has a substantially conical hollow main body portion, an outer peripheral surface of which conforms to the inner peripheral surface of the main plate. On the outer peripheral surface of the main body portion, a convex portion protruding toward the vicinity of the holes of the inner peripheral surface of the main plate is provided.

A globe assembly and method of manufacturing a raised relief globe including laminating the at least two plastic layer sheets as the printing sheet. The plastic sheet has the longitude and transverse. Both the two layers can have the same longitudinal strength and transverse strength. When laminating, maintain the longitude of first layer same direction as the transverse of second layer, so the transverse of the first layer has the same direction as the longitude of the second layer. A map design is then printed on the flat laminating plastic sheet. The plastic sheet is formed into a substantially hemispherical shape. A mold core is positioned on the back side of the sheet. A styrene backing is molded onto the hemispherical shaped sheet. A second molded hemisphere is produced in the substantially the same manner. The two hemispheres are then assembled as the raised relief globe.

The present invention relates to a cassette module for controlling fluid flows, in particular for use in blood treatment systems or in infusion systems, wherein the cassette module comprises at least one base body having means for the flow guidance of at least one fluid flow and at least two membranes which are at least sectionally directly or indirectly in contact with the base body, wherein at least one actuation element is arranged between the membranes by means of which the means for the flow guidance can be acted on.
