摘要： PURPOSE:To provide an insulation material which can easily form a closed-cell porous insulator of high mechanical strengths in good efficiency by integrating many low-permittivity microballoons by binding with a specified low-permittivity fluoropolymer and a specified fluorocopolymer. CONSTITUTION:A low-permittivity fluoropolymer (A) soluble in a fluorinated solvent (e.g. trademark Teflon AF 2400) is mixed with a low-permittivity fluorocopolymer (B) crosslinked into a substantially three-dimensional network structure (e.g. trademark Defenser 7702, a product of Dainippon Ink), a fluorinated solvent (C) (e.g. perfluorobenzene) and many low-permittivity microballoons (D) (e.g. glass microballoons). Component C is evaporated off from the mixture, and component D is integrated by binding with components A and B to produce an insulation material. When a solution of this insulation material is applied to a conductor, dried and cured, a high-strength closed-cell porous insulator can be easily formed.

摘要： PURPOSE:To obtain the tube being white and having a high contrast effect and to prevent it from being discolored with the lapse of time by constituting the tube by forming the inside layer by a tubular synthetic resin in which a fluid passage is formed in the inside, forming the intermediate layer by dispersing an X-ray contrast media in the synthetic resin and giving ultraviolet ray transmission resistance to the outside layer and forming the tube consisting of three layers. CONSTITUTION:An inside layer 1 consists of a tubular synthetic resin in which a fluid passage 4 is formed in the inside, and an ethylene tetrafluoride copolymerization resin is used. An intermediate layer 2 is formed by dispersing an X-ray contrast-media consisting of white bismuth into a synthetic resin, and a white bismuth compound is a white bismuth crystal consisting of bismuth oxide, bismuth nitrate and bismuth sulfate, and that which is 83-88weight% bismuth content is used, and by dispersing and mixing it is a synthetic resin within a range of 3-25weight%, the inside layer 1 is covered. The outside of the intermediate layer 2 is covered with an outside layer 3 formed by dispersing and mixing titanium oxide of 0.05-1.0mum particle size by 0.5-2.0weight% in the synthetic resin. In such a way, the appearance shows white and at the time of using it for the human body, there is no sense of incompatibility, ultraviolet rays are prevented as to its transmission by the outside layer 3, and yellowing of white bismuth is prevented.

摘要： PURPOSE:To make it possible to detect the leakage of fluid stably and highly accurately in a radiation environment by arranging a plurality of conductors in close proximity, and insulating the conductors with an inorganic insulating member which has radiation resistance property and can hold and secure the fluid. CONSTITUTION:Conductors 1 and 2 are combined in a cable shape, and a detecting element is formed. The conductor 1 is a high resistance wire, and the conductor 2 is a low resistance wire. The conductors 1 and 2 are surrounded with a detecting dielectric part 3 formed of glass fiber. The glass fiber has gaps which are suitable for holding and securing fluid. The conductors 1 and 2 having the dielectric parts 3 are surrounded with a first protecting braid 4 together, and the braid 4 is further surrounded with a second protecting braid 5. Thus the conductors are protected. When a point of the high resistance wire is electrically connected to the low resistance wire 2 through leaked water and the resistivity of the water is sufficiently low, both conductors are shorted. Therefore, when the resistances of the conductors 1 and 2 are measured, the resistance which is proportional to the length of the high resistance wire 2 to the leaking point is obtained and the distance can be simply operated.

摘要： PURPOSE:To enable long-period use, and also to maintain the flexibility of a tube in a good condition by providing hydroxyapatite powder on the wall surface of the tube consisting of polymeric materials, so that when the tube is inserted into the body, thrombosis can be hardly caused. CONSTITUTION:At least on the wall surface of a tube consisting of polymeric materials, hydroxyapatite powder is provided. Thereby the hydroxyapatite powder having a high antithromobotic property is dispersed at least on the wall surface of the tube, and since a part of particles is exposed on the surface, thrombosis is hardly caused. Further, since the hydroxyapatited is dispersed on the tube wall in a powder state, the flexibility of ther tube can be maintained in a good condition.
