摘要:
The present invention relates to a method and a device for assembling two tubes (1, 2), comprising a tubular joining sleeve and a conduit internal lining tube made from thermoplastic materials, by laser welding of two rotation contact surfaces (1-1, 2-1) applied against one another at the ends (1a, 2a) of the tubular sleeve of said lining tube, coaxially overlapping.

The present invention provides a resin part having high quality and produced by a simple manufacturing process, a photoelectric sensor using the resin part described above, and a method of manufacturing the resin part. A resin case includes a case (31) having a bonding surface (31c), and made of resin; an intermediate case (41) bonded to the bonding surface (31c) by welding, and made of resin that can transmit laser light; and a cap cover (21) arranged on the opposite side of the case (31) with respect to the intermediate case (41), standing on the intermediate case (41), and made of resin. The cap cover (21) includes a side portion (21a) standing from the intermediate case, and a top portion (21b) crossing the side portion (21a) on the position facing the bonding surface (31c) via the intermediate case (41). The height of the position (H) where the side portion (21a) and the top portion (21b) cross each other with the bonding surface (31c) being defined as a reference is the same on any position facing the bonding surface (31c).
摘要:
A laser beam is applied to surfaces to be welded to heat them, and welding between a metal member and a resin member or between a resin member and another resin member is completed, thereby providing an air-tight assembly. A laser beam is allowed to pass through a laser-transmitting resin and applied to a laser-absorbing material in contact with it to heat the latter, the heat then being used to fuse the laser-transmitting resin and the laser-absorbing resin. A laser-applying spot is moved to sequentially fuse and cure different portions. The upper portion (216) of a case (202) is made of a laser-absorbing resin, while the lower portion (218) is made of a laser-transmitting resin. With the case (202) fixed onto a laser-absorbing housing (200), a laser-applying position is moved along the side-wall (206) of the case (202) as much as one round at a constant speed while a laser beam is being applied to a contact surface (268) from an upper oblique direction external to the case (202) to complete welding. With a laser-transmitting-resin-made lid (204) fixed onto the case (202), a laser beam is applied to a contact surface (272) from the above to weld it.

In manufacturing a resin mold assembly, a first weld region of a light transmitting resin member (22) and a second weld region of a light absorbing resin member (21) are disposed facing each other, the first weld region of the light transmitting resin member (22) and the second weld region of the light absorbing resin member (21) are brought into pressed state in mutually facing direction, and a laser beam (12s) is scanned to make the laser beam (12s) be incident upon the light transmitting resin member (22), and repetitively radiated on the second weld region to heat and melt a whole of the first and second weld regions simultaneously, thereby welding the light transmitting resin member (22) and the light absorbing resin member (21).
摘要:
A catheter assembly comprising a first polymer, a second polymer and a first weld region. The first polymer forms a balloon having a first waist. The second polymer forms a catheter shaft. The first waist is positioned about a portion of the catheter shaft thereby forming the first weld region. The first weld region comprises a first weld and a second weld which engage the first waist to the catheter shaft. The first weld has a first longitudinal position and the second weld has a second longitudinal position, where the first longitudinal position is different from the second longitudinal position.

An article (10) is provided. The article includes a plastic material, and an expanded polytetrafluoroethylene (ePTFE) laminate (16) coupled to the plastic material, wherein the ePTFE laminate is laser welded to the plastic material.
摘要:
It is an object of the present invention to provide a container in which it is difficult for liquid to drip at a mouth portion having a good touch sensation by forming a structure in which a welded portion that was laser welded in a sealed container does not form a flange, and to carry out the achievement of making polymer material unnecessary and making excessive material in the wind-fastening portion unnecessary. Further, it is also an object to construct the lid and barrel of the vessel by using the same material, thereby facilitating the recycling of material. The sealed container in which a container body 1 having an opening 9 is sealed by a lid portion 3 which closes and covers said opening, comprising a welded portion 4, 14 in which an outer wall surface of a peripheral portion 2 of said opening or an edge 12 surface of said opening and an inner wall surface of said lid portion are laser welded in order to make it possible for at least an inner wall surface of the peripheral portion of said opening from an inner wall surface 6 of said container body to make contact with container contents.
