摘要： PROBLEM TO BE SOLVED: To provide a die for extrusion molding which can improve forceability, torque transmissibility, followability, kink resistance and the like without using a specific polymer such as a liquid crystal polymer and can perform a polymer orientation in a circumferential direction of a tube, and to provide a multilayer tubular product and its manufacturing method. SOLUTION: The die for extrusion molding has a tubular channel confluent part for polymer layers at which at least one of the die or a mandrel point can be rotated in the co-extrusion molding of a tubular laminated product with at least two or more layers. The method for manufacturing the tubular laminated product comprises the step of co-extrusion molding a material having a lower melt viscosity than that of inner and outer layer materials particularly for an intermediate layer.

摘要： PROBLEM TO BE SOLVED: To provide a thin heat pipe for regulating living body temperature that can be applied to a subject in which a heat receiving part and a heat radiation part are separated, and in which sufficient space is not provided between both parts.
SOLUTION: This thin heat pipe 51 is composed of a single turn part 53 (heat radiation part), a zigzag turn part 55 (heat receiving part) having a plurality of turns, and a straight part (heat transport part) 53b extended between both turn parts 53 and 55 to form a closed loop formed by communicating both ends of a single pipe with each other. The heat transport part is composed of two straight pipes, and the thin heat pipe 51 connects the heat receiving part and the heat radiation part to each other by one round. Due to connection by one round only, the heat transport part can be formed thin, thereby the heat receiving part and the heat radiation part separated through a narrow space can be connected for heat transport.

摘要： PROBLEM TO BE SOLVED: To provide a strong balloon having high separation resistance and wear resistance by composing it from an inner layer made of a crystalline plastic resin, an outer layer made of a highly soft resin, and an intermediate layer made of a relatively soft polymer alloy. SOLUTION: A balloon 1 is made of a three-layered thin-walled member consisting of an inner layer 7, an intermediate layer 8, and an outer layer 9. The inner layer 7, being the part securing the strength of the balloon 1, is given high strength and made thin as it is made from a crystalline plastic resin subjected to a drawing process. The intermediate layer 8, in order to serve to bond the outer layer 9 strongly to the inner layer 7, is made from a relatively soft polymer allay containing 60 to 70 parts by weight of the crystalline plastic resin used in the inner layer 7 and 30 to 40 parts by weight of a highly soft resin used in the outer layer 9. The outer layer 9, being the part protecting the inner layer 7 and serving mainly to ensure the flexibility of the balloon 1, is made of a material softer than the inner layer 7 and the intermediate layer 8, e.g., low density polyethylene.

摘要： PROBLEM TO BE SOLVED: To provide a catheter capable of weakening a jet of liquid discharged from the tip end of the catheter, preventing the tip end of the catheter from dropping out from the diverging point of a vessel, suppressing the reverse flow of the liquid, and decreasing the amount of the liquids leaked from the object position. SOLUTION: The catheter consists of a main body, a lumen 4 for guiding liquids that is made inside the main body and releases liquids to the tip end of the main body, a base 3 that connects with the base end of the main body and can introduce liquids to be poured into an organic body to the lumen 4 and side holes 5 that are set on the top end of the tube's main body and connected with the lumen 4. The side holes 5 are made as they incline to the longitudinal axis of the main body from the inside of the main body toward the outside at the tip end.

摘要： PROBLEM TO BE SOLVED: To facilitate the replacement of a guide catheter by arranging first and second coupling parts and a fixing mechanism to fix a guide wire on a main catheter or on an extended tube in a state where either or both of the first and second coupling parts are coupled. SOLUTION: A thread 11 is screwed down on a thread groove and as the screwing thereof proceeds, a tip taper part 12 of a first coupling part 6 advances inward to a connector and contacts a smaller diameter part of a second coupling part 8 to narrow the clearance of a slit 13. Then, the inner diameter of the tip taper part 12 also becomes smaller until the internal surface of the tip of the tip taper part 12 contacts a guide wire while the tip part holds the guide wire to lock. On the other hand, as the connector turns counterclockwise, the tip taper part 12 of the first coupling part 6 will not contact the second coupling part 8 and the clearance of the slit 13 expands to release the locking thereby enabling moving of the guide wire within the catheter 2.
