Abstract:
PROBLEM TO BE SOLVED: To provide a high pressure tank with a simple construction and a low cost which is durable to such a high pressure as 35 to 75 MPa despite of light weight. SOLUTION: A cylindrical reinforcing collar 10 is fitted to the gas extraction port 5 of a tank body 2, and the reinforcing collar 10 is fitted by shrink fit to the whole outside periphery from the gas extraction port 5 for taking out gas in the tank body 2 to an end plate 4.

Abstract:
PROBLEM TO BE SOLVED: To easily and inexpensively provide a high pressure tank endurable against high pressure not less than pressure until now. SOLUTION: This high pressure tank 1 projects a gas takeout part 5 on one end of a cylindrical body part 2 via a bowl-shaped mirror part 4 by plastically deforming a metallic short cylindrical blank material. The gas takeout part 5 is set in the thickness of at least three times the body part 2. The bowl-shaped mirror part 4 is gradually increased to the thickness of the gas takeout part 5 from the thickness of the body part 2 for going to the gas takeout part 5 from the body part 2.

Abstract:
PROBLEM TO BE SOLVED: To provide a compact and lightweight high-pressure tank excellent in pressure resistance. SOLUTION: A reinforced fiber layer 23 for coating an outer peripheral surface of a liner 2 of the high-pressure tank 1 is constituted of a first inner fiber layer 24 and a second inner fiber layer 25 composed of high rigidity fiber with a Young's modulus of 300 Gpa or more and a tensile strength of 3 Gpa or more, in which a thermosetting resin is impregnated and cured, and an outer fiber layer 26 composed of fiber with a breaking elongation of at least 2%, in which the thermosetting resin is impregnated and cured.

Abstract:
PROBLEM TO BE SOLVED: To provide a high pressure tank device A provided with a high pressure tank with high pressure gas filled, and a valve mechanism including a regulator valve for depressurizing a gas pressure in the tank, capable of reducing a size, preventing damage or the like of the valve mechanism, and facilitating handling of the valve mechanism or the like. SOLUTION: The valve mechanism 10 is provided on a gas outlet 3 of the high pressure tank 1 so as to be located in the tank 1. The valve mechanism 10 is provided with a capsule 11 mounted and fixed so as to be air-tight to the gas outlet 3 and face to an inside of the high pressure tank 1. A shut-off valve 20 for communicating and shutting off communication between an inside and outside of the tank 1 by opening and closing, and the regulator valve 31 for depressurizing the high pressure gas in the tank 1 are provided in the capsule 11.
Abstract:
PROBLEM TO BE SOLVED: To provide a high pressure tank having a smaller size, a lighter weight and superior pressure resistance. SOLUTION: A reinforcing fiber layer 23 for covering a liner 2 of the high pressure tank 1 at its outer peripheral face consists of an inside fiber layer 24 containing a highly rigid fiber having a Young's modulus of 350GPa and a rupture elongation of 0.7% or more, hoop wound and impregnated and hardened with a thermosetting resin, an intermediate fiber layer 25 containing a fiber having a Young's modulus of 280GPa or more and less than 350GPa and a rupture elongation of 1.5% or more and lese than 2.0%, helically wound and impregnated and hardened with a thermosetting resin, and an outside fiber layer 26 containing a fiber having a Young's modulus of 230GPa or more and less than 280GPa and a rupture elongation of 2.0% or more, helically wound at a high angle and impregnated and hardened with a thermosetting resin.

Abstract:
PROBLEM TO BE SOLVED: To reduce the cost of equipment, to make productive efficiency much higher, and to manufacture a fixing roller at low cost by realizing the manufacture of the fixing roller by using one kind of manufacturing machine for one pipe material. SOLUTION: After blank material 12 is heated over a given area from an aperture end, it is rotated around an axial center X1, In such a state, a molding roller 22 is made to press-contact with a heated area from the outside and rotated and moved, whereby the heated area is scrubbed, then side wall parts 3 are respectively integrally drawn at both ends of the trunk part 2 of a cylinder, and also the shaft part 5 of the cylinder is integrally drawn at the respective side wall parts 3. Thus, the fixing roller 7 is obtained. COPYRIGHT: (C)2004,JPO
