Method for joining a fluid conduit and a connection hub. There is provided a method for joining a fluid conduit 2 and a connection hub 7, wherein a fluid 2 conduit is provided having an at least partially transparent end section 1. Also provided is a connection hub 7 comprising a hub cavity 9 having a shape complementary to a shape of the end section of the fluid conduit 1. The end section of the fluid conduit 1 is at least partly introduced into the hub cavity 9 through an opening in the hub, wherein a contact interface between at least a lateral wall part of the end section 1 and a hub cavity 9 wall is established. The method includes heating a target zone 27 in the contact interface, for joining the fluid conduit 2 and the connection hub 7 at the target zone 27, by directing a light beam 29 across the at least partially transparent end section 1 of the fluid conduit 2 from a side of the fluid conduit 2 which is opposite a side of the target zone 27.

A method for joining two components of a meltable material comprises the steps of providing a first component having a first border region and a second component having a second border region, placing the second component relative to the first component so as to form an overlap between the first border region and the second border region under a gap between the first border region and the second border region, continuously heating opposed sections of the first border region and the second border region at the same time through at least one energy source arranged in the gap at least partially, continuously providing a relative motion of the at least one energy source along the first border region and the second border region in the gap, and continuously pressing already heated sections of the first border region and the second border region onto each other.

A laser-welded body includes at least three of resin members, which contain a thermoplastic resin including: a first resin member which is a laser-irradiated subject, has an absorbance a.sub.1 of 0.01 to 0.12; a second resin member which has an absorbance a.sub.2 of 0.1 to 0.9 and includes a butted part where ends of one or more resin members are brought into contact with each other; and a third resin member which has an absorbance a.sub.3 of 0.2 to 3.8, and the absorbances a.sub.2, a.sub.3 exhibited by the second resin member and the third resin member are attributed to the inclusion of nigrosine as a laser beam absorbent therein, and the resin members are overlapped in the above mentioned to form contacted parts at these interfaces, at least a part of the butted part and/or the contacted parts are laser-welded.

In order to thermally cure a thermosetting adhesive quickly and with less energy, the bonded article (10) according to the present invention comprises an adherend member (1) having a thermal conductivity of 1 w/m.Math.K or more, an adherend member (2) made of a material which can adhere to the adherend member (1), and an adhesion portion that is formed of a cured product of a thermosetting adhesive (3) and that is in contact with both the adherend member (1) and the adherend member (2), wherein the adherend member (1) has a heat transfer-inhibiting structure (4) which inhibits the transfer of heat from a portion thereof in contact with the adhesive (3) to a peripheral portion thereof.

An optical cable and method for forming an optical cable is provided. The cable includes a cable jacket including an inner surface defining a channel and an outer surface and also includes a plurality of optical fibers located within the channel. The cable includes a seam within the cable jacket that couples together opposing longitudinal edges of a wrapped thermoplastic sheet which forms the cable jacket and maintains the cable jacket in the wrapped configuration around the plurality of optical fibers. The method includes forming an outer cable jacket by wrapping a sheet of thermoplastic material around a plurality of optical core elements. The method includes melting together portions of thermoplastic material of opposing longitudinal edges of the wrapped sheet such that a seam is formed holding the sheet of thermoplastic material in the wrapped configuration around the core elements.

There is provided container sealing apparatuses and methods for sealing openings of containers with film. The apparatuses comprise: a pressing member configured to press a film into contact with a container; and a sealing beam source configured to emit one or more sealing beams, each of said sealing beams being incident on the container and/or the film, each of said sealing beams being incident local to a respective part of the pressing member which engages the container so as to join the film to the container; the container sealing apparatus being configured to move the container relative to the pressing member, such that a region of the container which is engaged by the pressing member changes.

A method for processing a resin member includes: irradiating a first member comprising a resin with first light of a first wavelength that causes electronic excitation of the resin; and irradiating the resin electronically excited through irradiation with the first light with second light of a second wavelength longer than the first wavelength. A wavelength range of the second wavelength is within a wavelength range in which light absorption of the resin increases through electronic excitation of the resin.

A welding device includes a pair of pressure rollers for pressurizing a web and a strip member, a feed device configured to intermittently or continuously feed the web and the strip member through the pair of pressure rollers, and the laser device configured to irradiate the web or the strip member with a laser beam at a position upstream of the pair of pressure rollers. The welding device may include a movement device configured to move the pair of pressure rollers upstream with respect to the web and the strip member during pause or stop of feed. Alternatively, the feed device may pause or stop the web and the strip member after retracting the web and the strip member by a certain length.

The present invention relates to a pouch-shaped secondary battery sealing apparatus and a pouch-shaped secondary battery manufacturing method capable of radiating an infrared laser to a sealed portion in an overlapping state, whereby it is possible to increase sealing force, to prevent occurrence of wrinkles, and to reduce sealing time when forming a sealed portion of a pouch-shaped secondary battery case.

A woven fabric seam area is provided including a top surface and a bottom surface, with the woven fabric being formed of warp yarns interwoven with weft yarns in a repeating pattern, and either the warp yarns or the weft yarns are formed at least in part of a laser energy absorbent material. Within the fabric seam area yarns formed of laser energy transparent material can be bonded to yarns being formed at least in part of a laser energy absorbent material by laser welds in order to maintain or achieve a desired flexibility and/or shear resistance of the fabric. A method of forming such a fabric seam area is also provided.
