Abstract: A stent 51c is formed by braiding a plurality of filament threads containing a biodegradable polymer into a cylindrical braid, and connecting points 53a-53d at end portions of the filament threads constituting the braid are arranged in two or more rows in a length direction of the braid. Elastic threads 54a-54d are each disposed outside at least a part of the stent 51c and along at least a part of the stent in the length direction including the vicinity of either one of end portions of the stent. One end of each elastic thread is fixed to the vicinity of the end portion of the stent, and the other end is fixed to any portion of the stent. In a state in which the stent is radially contracted, tension may be applied to the elastic threads. Thus, provided are a stent that is easy to load into a delivery system and also facilitates the expanding operation, as well as a medical device including the stent.

Abstract: An ultrahigh molecular weight polyolefin yarn of the present invention has been drawn and has a melting point that is determined as a maximum peak temperature measured by a differential scanning calorimeter (DSC) at a temperature rise rate of 20° C./min, and the melting point is higher than a melting point of the yarn before drawing. In a production method of the present invention, a drawing bath (3) that includes a hollow yarn path (14) and a jacket portion (13) in which a heated liquid circulates is placed in a drawing zone, and the yarn is heated and drawn while passing through the yarn path (14) in a non-contact manner. A drawing device of the present invention includes a feeder (1) for feeding a yarn, a drawing bath (3) for heating and drawing the yarn, and a winder (5) for winding up the drawn yarn. The drawing bath (3) includes a hollow yarn path (14) and a jacket portion (13) in which a heated liquid circulates.

Abstract: The present invention provides a resin composition suitable for molding a microscopic structure that has small cure shrinkage, good mold transfer properties and excellent properties for post-processing such as polishing processing and laser processing. Such a resin is a thermosetting resin composition comprising 95 to 35 wt % of a thermosetting resin and 5 to 65 wt % of organic filler having a particle size of 10 ?m or less. From such a resin, an ink ejecting apparatus having a microscopic structure, for example, a nozzle of a diameter of 30 ?m, is integrally molded.

Abstract: The present invention provides a method that allows ultra-precisely bonding by which a complete sealingly bonded molded article can be produced in a simple manner. This method includes (1) fixing an injection molded article (a) at a position (predetermined bonding position) formed with a mold; (2) mounting and moving a molded article (b) to be bonded to the injection molded article (a) to the predetermined bonding position within the mold; (3) positioning the molded article (b) at the predetermined bonding position; and (4) closing the mold for bonding.
