A functional element of metal having a flange of larger diameter from an attachment surface and a centering section arranged inside the attachment surface and extending away from the flange, characterized in that an adhesive is arranged around the cylindrical section and adjacent to the attachment surface.

An intravenous delivery system may have a liquid source containing a liquid, tubing, and an anti-run-dry membrane positioned such that the liquid, flowing form the liquid source to the tubing, passes through the anti-run-dry membrane. The anti-run-dry membrane may be positioned within an exterior wall of a drip unit, and may have a weld surface secured to a seat of the exterior wall via application of compression to press the weld surface against the seat, and application of coherent light or vibration. In response to application of the coherent light or vibration, localized melting may occur, causing the weld surface to adhere to the seat. The anti-run-dry membrane may be modified to have a melting point close to that of the seat. Ultrasonic or laser welding may be applied in a manner that causes portions of the seat to melt and flow into pores of the weld surface.

A resin joined body includes a thermoplastic resin molded body and a thermosetting resin molded body. The thermosetting resin molded body has a thermoplastic resin portion embedded in the thermosetting resin molded body and exposed at a portion of a surface of the thermosetting resin molded body. The thermoplastic resin portion of the thermosetting resin molded body is welded to the thermoplastic resin molded body thereby joining the thermosetting resin molded body to the thermoplastic resin molded body.

The disclosure relates to reversible bonded structural joints using active adhesive compositions that can allow for dis-assembly, repair, and re-assembly. The disclosure is particularly directed to the adhesive composition material, irrespective of the type of the substrate(s) being joined. The adhesive composition can include any thermoplastic adhesive material that can be remotely activated for targeted heating of just the adhesive composition (e.g., and not the surrounding substrates being joined) via the inclusion of electromagnetically excitable particles in the adhesive composition. The substrates can be any metal material, any composite material, any hybrid material, or otherwise. The disclosed adhesive compositions allow for recyclability of parts at the end of their lifetime and repair/replacement of parts during their lifetime.

A method of joining polymer components includes additively manufacturing first and second mating features on first and second polymer components such that a mechanical lock is created through undercut geometric features of an adhesive material when the polymer components are joined. Adhesive is added between the mating components to strengthen the joint.

A resin member contains a thermoplastic resin and is bonded to another resin member by ultrasonic welding. The resin member includes: a melting start portion to which contact pressure is applied during the ultrasonic welding; a groove unit that is formed around a periphery of the melting start portion; and at least one wall that is formed so as to cross a direction from the melting start portion toward an outside and partitions the groove unit.

The present disclosure relates to a battery module that includes a housing having a first protruding shelf along a first perimeter of the housing, a second protruding shelf along a second perimeter of the housing, where the first and second protruding shelves each include an absorptive material configured to absorb a first laser emission. The battery module also includes an electronics compartment cover configured to be coupled to the housing via a first laser weld, and a cell receptacle region cover configured to be coupled to the housing via a second laser weld. The electronics compartment cover has a first transparent material configured to transmit the first laser emission toward the first protruding shelf and the cell receptacle region cover has a second transparent material configured to transmit the first laser emission or a second laser emission toward the second protruding shelf.

A secondary battery includes an electrode assembly, a packaging bag, an electrode lead and an insulating member. The electrode assembly is housed in the packaging bag, an edge of the packaging bag has a sealing portion, and the electrode lead is connected to the electrode assembly and passes through the sealing portion; the sealing portion includes a main body region, a first step region and a first transition region, the first step region is located on two sides of the electrode lead in a thickness direction, the main body region and the first transition region are located on a same side of the first step region in a width direction, and the first transition region is connected between the first step region and the main body region; the insulating member surrounds an outer side of the electrode lead and isolates the sealing portion from the electrode lead.

A vehicle lamp 10 includes a lamp body 11, a sealing material 42, and a lens member 12 and a leg portion 41. A groove portion 31 is formed in the lamp body 11. The sealing material 42 is filled in the groove portion 31. The leg portion 41 is provided on the lens member 12. The leg portion 41 is inserted into the groove portion 31 to thereby fix the lamp body 11 and the lens member 12 together via the seal material 42. A narrow portion 51 is provided at a bottom side of the groove portion 31 and a wide portion 52 is provided at an opening 35 side of the groove portion 31. A gap of the wide portion 52 is wider than the gap of the narrow portion 51. The amount of sealing material 42 used in vehicle lamp 10 is limited while ensuring an easy assemblage.

A battery state detection device includes a casing (8) and a lid part (24). The casing (8) includes a board storage space (23) that stores a circuit board. The casing (8) includes an open mouth through which one side of the board storage space (23) is opened. The lid part (24) closes the open mouth of the casing (8). The lid part (24) is provided with a tapered surface (77). The casing (8) is provided with a contact portion (78) that can be in contact with the tapered surface (77). In a state where the tapered surface (77) and the contact portion (78) are in contact with each other, ultrasonic welding between the casing (8) and the lid part (24) is performed.
