摘要： PROBLEM TO BE SOLVED: To reliably prevent buoyancy material from leaking out even if a joint part of the new pipe swells when a new pipe is given buoyancy and is jacked and inserted in a sheath pipe 1. SOLUTION: A water shut off member 12 on one end of the sheath pipe is formed as one unit of rubber, and consists of a cylindrical part 12a fixed on an inner surface of the sheath pipe 1 by a machine screw, a flap 12b facing an axial center of the sheath pipe on an inner circumference whole surface, and a solid cross section round rubber ring 12c of larger diameter than a tip end thereof on a tip end whole circumference of the flap 12b. The flap has normally flexibility and flexibly correspond to change, fluctuation of size (diameter) of the new pipe sliding in the annular shape part of the flap. Then since a solid cross section circular rubber ring is larger in a diameter than a flap tip edge, the flap is not easily influenced by bent of the flap, sure press contact to the new pipe outer circumference surface is maintained even if the flap is deformed to secure water tightness.

摘要翻译：要解决的问题：为了可靠地防止浮力材料泄漏，即使新管道的接头部分在新的管道被赋予浮力的同时膨胀并被套管并插入护套管1中。解决方案：A 护套管一端的隔水部件12形成为橡胶的一个单位，并且由通过机械螺钉固定在护套管1的内表面上的圆筒部12a，面向轴向中心的翼片12b 内管整体表皮上的护套管，以及在翼片12b的前端全圆周上比其前端大的直径的实心截面的圆形橡胶环12c。翼片具有通常的灵活性，并且柔性地对应于在翼片的环形部分中滑动的新管的尺寸（直径）的变化。然后由于固体截面的圆形橡胶环直径大于翼片尖端边缘，所以翼片不容易受到翼片的弯曲的影响，即使翼片变形，也确保与新管外周表面的压力接触以确保水密。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To obtain both non-staining property and transparency of a tube to be suitably used in a carrier system of food and drink by providing an internal layer in which an antibacterial agent of prescribed quantity is added to a transparent silicone rubber as a matrix, and an external layer made of transparent silicone rubber and formed so as to cover the internal layer. SOLUTION: A silicone rubber tube 1 is formed into a double layer structure of an external layer 2 made of addition reaction type silicone rubber with high transparency and an internal layer 3 made of a material in which the same silicone rubber is used as a matrix and an antibacterial agent 4 is added to the matrix. By using zeolite carrying metallic silver as the antibacterial agent and making the internal layer 3 considerably thinner than the external layer 2, high transparency is obtained as the whole of the tube 1. When the tube 1 is manufactured, powders of base polymer, cross-linking agent, platinum catalyst and antibacterial agent 4 are mixed with silicone oil and the obtained base compound is processed so as to be co-extruded and molded as a tube material.
