Thermoplastic resin composition
The present invention is to provide a thermoplastic resin composition capable of obtaining a molded article that is excellent in appearance after laser welding and a color tone and has sufficient impact property as a resin member. In addition, the present invention is to provide a molded article that is excellent in appearance after laser welding and a color tone and has sufficient impact resistance as a resin member. As a result of intensive studies, the present inventors have found that the above problems can be solved by controlling a thermoplastic resin composition containing rubber-containing graft copolymer to have appropriate reflectance in the visible light and absorptivity in the near-infrared region, and have completed the present invention.

BALLOON CATHETER AND METHOD OF MANUFACTURING BALLOON CATHETER
A balloon catheter is disclosed which allows easier fusion-bonding between an inner tube shaft and an outer tube shaft and in which the inner tube shaft can be prevented from being warped when the inner tube shaft passes through a stenosed site, and a method of manufacturing such a balloon catheter. The balloon catheter includes an inner tube shaft having a first layer and a second layer located on an inner surface side of the first layer. The outer tube shaft is fusion-bonded to the first layer and recessed toward the inner tube shaft side. The first layer is formed of a material having higher optical absorption property than the outer tube shaft and the second layer. The second layer is formed of a material having a melting point higher than that of the first layer.

HIGH STRENGTH POLYMER METAL COMPOSITES AND METHODS OF MAKING THEREOF
The present invention provides polymer-metal composites free of adhesives and methods of making same. In particular, the present invention takes advantage of a unique metallic bonding surface created by exposure to a laser whereby micron-sized fragments are fixed to the metallic bonding surface such that a high strength bond with polymeric material is created upon exposure to a second laser.
FILTRATION DEVICE
The present disclosure relates to a filtration device comprising a plurality of hollow fiber membranes, a process for its production, and its use for the dead-end filtration of infusion liquids.
Laser welding system and method using cooling mask to control the width of the weld
A laser welding method and system for joining portions of first and second workpieces of thermoplastic material that is partially permeable to a laser beam but absorbs radiation from the laser beam. The first and second workpieces, which are made of material that absorbs radiation from a laser beam, are clamped together. A mask is placed on a first surface of the first workpiece, the first surface being opposite the surface engaging the second workpiece. The mask is impermeable to a laser beam and forms a slot for passing a laser beam to the portion of the first surface of the upper workpiece exposed by the slot, so that heating and melting of the material of the workpieces is limited to the width of the slot. A laser beam is directed onto the slot and moved in a manner to illuminate the slot to melt and join the workpieces.
METHOD FOR CREATING A CONNECTION BETWEEN COMPONENTS CONSISTING OF DIFFERENT PLASTIC MATERIALS AND ASSOCIATED CONTAINER WITH POURING ATTACHMENT
A method for creating a connection between components of different plastics. A first section can consist of a first plastic whose main constituent is polarised plastic, and a second section can consist of a second plastic whose main constituent is non-polar plastic. The method includes creating the connection between the first section and the second section with help of beamed-in laser energy; subjecting the first section to incident laser energy, the first section being at least partly transparent with regard to the incident laser energy; and absorbing beamed-in laser energy at least partly in a joining region, in which the first and the second sections bear on one another in an overlapping manner amid action of force, to create a positive, unreleasable connection between the two components.
System And Method For Simultaneous Welding Of Plastic Bags Using A Carrier Film
A laser welding system is directed to simultaneously joining respective layers of a first bag and a second bag. The system includes a first film layer adjacent to a second film layer for forming the first bag, and a third film layer adjacent to a fourth film layer for forming the second bag, each layer of the plurality of film layers being made of a thermoplastic material that absorbs laser radiation having a wavelength of about 2 microns. A non-absorbing carrier film layer is positioned between the second film layer and the third film layer, the non-absorbing carrier film layer being made of a material that transmits substantially all energy of the laser radiation. A laser source applies the laser radiation toward portions of the plurality of film layers to be joined, forming the first bag generally simultaneously with the second bag.
