摘要： A double tube from which a balloon catheter having a high rigidity and a low fluid resistance can be easily produced by means of an extruder or the like, an apparatus for producing the double tube, a balloon catheter produced by using the double tube, and a process for producing the balloon catheter are provided. The double tube comprises an outer tube having a lumen extending from the distal end to the proximal end, and an inner tube which is provided within the outer tube and has a lumen extending from the distal end to the proximal end, wherein a longitudinal member in the strip form is provided as a connecting member which continuously connects the inner surface of the outer tube to the outer surface of the inner tube in the axial direction. A balloon catheter can be easily produced by using this double tube. An apparatus for producing a double tube is also provided which comprises a first extruding means for extruding a resin for forming an outer tube portion, a second extruding means for extruding a resin for forming an inner tube portion, and a die for forming into tubes respectively from the resins extruded from the first extruding means and the second extruding means.

摘要： A parallel robot comprises a base, three set of arm assemblies disposed on the base at a predetermined spacing, and a bracket member which is supported by the arm assemblies and to which an end effector is attached. Each of the arm assemblies comprises a pair of motors mounted on the base to face each other with a predetermined clearance and a pair of arms which are supported by the motors to be swung, respectively. Each of the arms comprises a first arm portion and a second arm portion. The first arm portion and the second arm portion of each arm are connected with each other through a first joint means, and the second arm portion of each arm is connected with the bracket through a second joint means.

摘要： A wheelchair fixing apparatus (2) according to the present invention includes belts (21) having connecting members (23) which can be attached to and detached from fixing hardware pieces (3) installed on a floor and winding devices (22) for winding up and accommodating the belts (21) and the winding devices (22) are disposed on the wheelchair (1). Therefore, the fixing hardware pieces (3) to which the belts (21) are connected through the connecting members (23) suffice as the floor-side equipment. Moreover, with this apparatus, a user of the wheelchair can perform the fixing operation by himself/herself. Even when a caretaker performs the operation, the burden on the caretaker in performing the operation can be reduced. Furthermore, the apparatus need not be carried by the caretaker, nor need it be ready in advance in a place where the wheelchair (1) is to be fixed.
摘要翻译：根据本发明的轮椅定影装置（2）包括具有连接构件（23）的带子（21），该连接构件可以安装在安装在地板上的固定五金件（3）和用于卷绕的卷绕装置（22）并且容纳皮带（21）和卷绕装置（22）设置在轮椅（1）上。因此，带（21）通过连接构件（23）连接的固定件（3）足以作为地面侧设备。此外，利用该装置，轮椅的使用者可以自己进行定影操作。即使看守员执行操作，也可以减轻看守人在执行操作中的负担。此外，该设备不需要由看守者携带，也不需要事先在轮椅（1）固定的地方准备好。
