    • A balloon catheter having multiple tubular members, an adaptor member connected thereto and a balloon for dilation of constricted blood vessel, wherein the peeling strength of the balloon surfaces when adheres to each other is 0.06 N or more and the modulus of the balloon in the axial direction is 100 N/mm2 or more, and wherein the coated resin composition contains a hydrophilic resin that is lubricating when wet. Furthermore, the outer surface of the balloon is made of a polyamide elastomer resin composition having a durometer hardness of 55 D or less. Thus, there can be provided a balloon catheter excelling in handling property, for which keeping the balloon highly penetrable through the stricture site as the accordion phenomenon of the balloon is prevented, and simultaneously preserving the other properties of the balloon (flexibility of balloon, wrapping dimension, and dilation/shrinkage response etc.).
    • 具有多个管状构件的球囊导管,连接到其上的适配器构件和用于扩张收缩血管的气囊,其中当彼此粘附时球囊表面的剥离强度为0.06N以上,并且球囊在轴向上的模量 方向为100N / mm 2以上,并且其中涂布的树脂组合物含有在湿润时润滑的亲水性树脂。 此外,球囊的外表面由硬度为硬度为55D以下的聚酰胺弹性体树脂组合物制成。 因此,可以提供一种气囊导管,其处理性能优异,保护气囊能够通过狭窄部位高度穿透,因为防止气囊的手风琴现象,同时保持球囊的其他特性(球囊的柔韧性 尺寸和膨胀/收缩响应等)。

    • A device for continuously measuring and correcting a tackiness of a sheet of rubber material including a feeding unit for continuously feeding an unvulcanized rubber sheet along a flat support surface and a rotatable roller in contact with the unvulcanized rubber sheet, whereby the roller is rotated by the movement of the unvulcanized rubber sheet, and entrained in the sheet feed direction due to a tackiness of the unvulcanized rubber sheet. A load cell is connected to the roller via a linkage, for measuring a resistance to the rolling of the roller, i.e., a change of a position of the roller entrained in the sheet feed direction. The device also includes a correcting unit for correcting a tackiness of the sheet of unvulcanized rubber material, the correcting unit being controlled by a control element in response to an output from the measuring unit, in such a manner that the correcting unit acts on the surface of the unvulcanized rubber sheet of rubber material when an output from the measuring unit is outside a predetermined range of tackiness.
    • 一种用于连续地测量和校正橡胶材料片的粘性的装置,包括用于沿着平坦支撑表面连续供给未硫化橡胶片的进料单元和与未硫化橡胶片接触的可旋转辊,由此辊由 未硫化橡胶片的移动,并且由于未硫化橡胶片的粘性而夹带在片材进给方向。 负载传感器通过连杆连接到辊子上,用于测量辊的滚动阻力,即夹带在送纸方向上的辊的位置的变化。 该装置还包括校正单元,用于校正未硫化橡胶材料片的粘性,校正单元由控制元件响应于来自测量单元的输出而被控制,使得校正单元作用在表面上 当来自测量单元的输出超出预定的粘性范围时,橡胶材料的未硫化橡胶片。
