A process of manufacturing a down product comprises at least one bonding pattern line for the compartment separation without forming sewing holes by printing and drying a heat-reactive adhesive on the inner surface of an inner fabric, an optional mesh material and/or an outer fabric in a predetermined pattern, laminating said inner fabric, optional mesh material and/or outer fabric, and then high-frequency heating them under pressing with a pressing pattern the same as the printing pattern to bond the inner fabric, optional mesh material and outer fabric. Accordingly, it is possible to manufacture a down product having a bonding pattern line composed of a bonding line with excellent adhesiveness and durability and an aesthetically excellent pattern line with good clearness and finishing quality as well as to achieve a mass production of down products by mechanization and automation.

An object of the present invention is to provide a process for producing a surface-modified molded article, whereby surface layer strength of a molded article can be enhanced, and a molded article containing an organic polymer compound with low adhesive property, such as a fluororesin, can be bonded to an adherend without the use of an adhesive, and whereby a treatment step or an apparatus in an atmospheric-pressure plasma treatment are not complicated, and to provide a process for producing a composite of the surface-modified molded article and an adherend. The present invention is a process for producing a surface-modified molded article wherein a surface of the molded article containing an organic polymer compound is subjected to an atmospheric pressure plasma treatment to introduce a peroxide radical with adjusting the surface temperature of the molded article to (melting point of the organic polymer compound −120° C. or higher.

A flow sensor includes an auxiliary channel having an opening into which a fluid to be measured is taken; a sensor element that measures the flow of the fluid to be measured; a housing that accommodates electronic parts; and a resin cover. The flow sensor is configured such that junctions of the housing and the cover are formed in locations where first target weld portions, which are formed so that the circuit chamber is surrounded, face each other and second target weld portions, which are disposed for additional reinforcement of the joints, face each other on a bonding face of the housing and a bonding face of the cover with a step being provided. The positioning of the housing and the cover is determined, and the first target weld portions are welded to each other and second target weld portions are welded to each other by way of laser radiation.

A food sterilization tube includes a layer including a fluoropolymer, wherein the fluoropolymer includes a copolymer of tetrafluoroethylene and perfluoropropyl vinyl ether (PFA), a fluorinated ethylene propylene copolymer (FEP), polytetrafluoroethylene (PTFE), or combination thereof, wherein the fluoropolymer has a dielectric constant of less than 3 as measured by ASTM D150.

A neurovascular catheter extension segment is provided, such as for distal neurovascular access or aspiration. The neurovascular catheter extension segment includes 1) an elongate flexible control wire having a proximal end and a distal end and 2) a tubular extension segment having a side wall defining a central lumen carried by the distal end of the control wire. The side wall of the tubular extension segment includes a tubular inner liner, a tie layer separated from the lumen by the inner liner, a helical coil surrounding the tie layer, and an outer jacket surrounding the helical coil. The extension segment may be introduced into the proximal end of a neurovascular catheter and advanced distally to extend beyond the catheter and thereby extend the reach of the catheter.

The present invention is a method for manufacturing inflatable bladders for use in articles of manufacture. The method includes the steps of providing a first polymer film, applying a curable release coating to the polymer film in a pattern that corresponds to the configuration of the inflatable bladder, curing the release coating to the first polymer film, providing a second polymer film with the first polymer film to form a layered element such that the release coating is disposed between the polymer films, positioning the layered element between two plies of material, applying heat and pressure to adhere the polymer films together except in the area where the release coating has been applied to form an inflatable compartment surrounded by a sealed perimeter, and removing the plies of material from the adhered first and second polymer films.
