Providing a fluid coupling, in which a coupling member is readily retained by a retainer and the retainer can be readily attached to or detached from the coupling member, and a retainer for such a fluid coupling. A retainer includes an annular gasket retaining portion for retaining a gasket therein and an annular coupling member retaining portion which has an inner diameter greater than that of the gasket retaining portion and retains one coupling member. At an inner circumference of the gasket retaining portion and an inner circumference of the coupling member retaining portion are formed annular grooves respectively, for holding therein elastic rings respectively.
摘要:
A method for manufacturing a superconducting magnet comprising the steps of applying a bonding agent on a length of a superconductor by passing the superconductor through a bath of the bonding agent to thereby coat the superconductor with the bonding agent. The superconductor coated with the bonding agent is simultaneously wound to form a winding which is then hardened by heating for example to form a rigid winding without voids.

A process for producing interior vehicular trim, comprising covering the surfaces of a substrate to which a nap-raised ornamental member has been applied, and removing the synthetic resin surface material at the part thereof covering the nap-raised ornamental member along a weld line. The synthetic resin surface material is welded and melt-cut on the peripheral edge of the ornamental member by carrying out the welding while the synthetic resin surface material is lifted up by force from the surface of the nap-raised ornamental member over the part thereof covering the ornamental member. An apparatus for producing interior vehicular trim, comprises an upper platen disposed to oppose matchably to a lower platen for supporting the substrate to which the nap-raised ornamental member has been partly applied, to effect welding of the synthetic resin surface material which was applied over the surface of the substrate, the welding being carried out along the peripheral edge of the ornamental member. The portion of the synthetic resin surface material covering the nap-raised ornamental member is removed by melt-cutting it along the welded line. A lift-up arrangement provided for lifting up the synthetic resin surface material at the part thereof covering the nap-raised ornamental member from the surface of the nap-raised ornamental member at least during the welding and melt-cutting steps.

A superconducting magnet device which is capable of protecting at the time of quenching a superconducting magnet divided into a plurality of sections comprises a superconducting magnet circuit which is formed by sequentially connecting in series coil pairs 1a, 1b, and 2a, 2b which are positioned symmetrically with respect to a ferromagnetic shield 6, and by connecting in parallel to the superconducting coils 1a, 1b and 2a, 2b superconducting coil protecting elements 3a and 3b which protect the superconducting coils 1a, 1b and 2a, 2b when the voltage at the ends of the coils has exceeded a predetermined value. If quenching occurs at the superconducting coils 1a, 1b and 2a, 2b, generation of an unbalanced electromagnetic force, a local electromagnetic force, etc., against the ferromagnetic shield 6 is prevented, so that the support structure for the superconducting coils and the ferromagnetic shield can be simplified.

An object of the present invention is to provide a fluid coupling, even if it has a large diameter, in which a coupling member can be readily retained by a retainer and the retainer can be readily attached to or detached from the coupling member, and a retainer for such a fluid coupling. A retainer 5 includes an annular gasket retaining portion 21 for retaining a gasket 4 therein and an annular coupling member retaining portion 22 which has an inner diameter greater than that of the gasket retaining portion 21 and retains one coupling member 2. At an inner circumference of the gasket retaining portion 21 and an inner circumference of the coupling member retaining portion 22 are formed annular grooves 23 and 24, respectively, for holding therein elastic rings 25 and 26, respectively.
