A composite member includes a metal sheet having a bent portion formed by bending, and a resin member joined to at least a part of the bent portion. The metal sheet includes an opening provided on an inner side of the bent portion, and a tapered recess that tapers off from an outer side of the bent portion toward the opening. The resin member includes an inner resin part filled in the recess, and an exposed resin part provided to be continuous with the inner resin part and to extend to an inner surface of the bent portion through an edge portion of the opening.

The invention relates to a nozzle for use in a device for administering a liquid medical formulation, to a method for producing the nozzle in the form of a microfluidic component and to a tool for producing microstructures of the microfluidic component. The nozzle is formed by a plastics plate with groove-like microstructures which are covered by a plastics cover on the longitudinal side in a fixed manner. The production method includes a moulding process in which a moulding tool is used, which moulding tool has complementary metal microstructures which have been produced from a semiconductor material in an electrodeposition process by means of a master component.

An implantable venous device includes a catheter including a passage; a locking nut including a channel for receipt of the catheter and an annular convex end; an injection seat including a base, a peripheral wall, and a mounting member projecting out of the wall; a connecting tube projecting out of the mounting member and including a bulged central portion and an annular curved outward end with the locking nut secured onto the bulged central portion; a base member including a groove; a housing including a top opening, a clamping portion on a periphery of the top opening, and a passageway through a bottom edge for receipt of the base member with the injection seat fastened in the housing, and with the locking nut in the groove; and an implant member in the top opening and including a peripheral flange urged downward by the clamping portion.

A method is disclosed for coating a projectile for use in an ammunition cartridge. A polymer jacket is applied to an undersized projectile core of a first standard caliber to bring the outer dimensions of the jacketed projectile into compliance with those of a second, larger caliber projectile. The polymer jacket coating may produce a non-uniform outer diameter of the polymer jacketed projectile and may include a plurality of circular cavities defined therein. The polymer-jacketed projectile may be a bullet for pistol or rifle ammunition, or a pellet, or shot for use in a shotgun shell.

Methods of embedding a heating circuit in an article fabricated by additive manufacturing. The methods describe techniques such as co-extruding a wire, capable of being heated, along with print material in additive manufacturing of the article, and placing a pre-shaped wire capable of being heated between adjacent layers of the article. A third method includes dispensing a wire, capable of being heated, during the additive manufacturing of the article, and compacting the wire into the printed material. An apparatus for embedding a heating circuit in an article fabricated by additive manufacturing. The apparatus contains a wire dispenser, a cutter to control the length of the wire dispensed, and a compactor capable of embedding the wire capable of being heated into the printed material. An article made by additive manufacturing is disclosed. The article contains at least one heating element embedded in the article during the additive manufacturing process.

An embodiment of an apparatus includes a raw material deposition head in communication with a working surface, an energy beam generator, a wire feed, and an ultrasonic head. The energy beam generator is directed toward the working surface for consolidating raw material disposed on the working surface by the raw material deposition head. The wire feed dispenses pre-formed wire to the raw material consolidated on the working surface by an energy beam from the energy beam generator. The ultrasonic head is directed to embed the dispensed pre-formed wire into the consolidated raw material.

An apparatus for roll forming thermoplastic composites comprises a plurality of thermoplastic composite material spools, a plurality of thermoplastic composite material rollers, a plurality of sheet metal spools, a plurality of welding rollers, an oven, a forming roller, a pair of pinch rollers. The thermoplastic composite material spools retain plies of thermoplastic composite material. The plies flow through the thermoplastic composite material rollers to form a layup. The sheet metal spools retain metal sheets. The metal sheets and the layup flow through the welding rollers to form a metal composite material laminate. The oven heats the metal composite material laminate. The forming roller imparts a curvature to the metal composite material laminate. The pinch rollers receive the metal composite material laminate from the forming roller, pull the metal composite material laminate, and output the metal composite material laminate in a heated and compressed state.

A syringe and needle assembly including a needle tube having a needle tip for puncturing a living body. A syringe is formed integrally with the needle tube. The syringe includes a main body to be filled with a drug and a securing section that is formed integrally with the main body. The securing section has a close contact area that has an outer peripheral surface that contacts an inner surface of a cap when the cap is attached, and a connection area that connects the close contact area and the main body to each other. A needle tip of the needle tube protrudes from the close contact area, and a parting line is formed on the securing section. The outer peripheral surface of the close contact area has no parting lines.
