A hose with a protector comprises: a tubular-shaped hose body 10; a tubular-shaped protector 20 which is coaxially provided in the state in which it covers the outer peripheral surface of the hose body 10; a tubular-shaped engager 30 which bonds the hose body 10 and the protector 20 integrally at both edge portions thereof and which forms an inserting opening into which a nipple is inserted and bonded. By producing the hose body out of resin and producing the protector out of rubber, the present hose with a protector can obtain heat resistance and anti flame resistance which are suitable for a filler hose and which are necessary at the time of vehicle fire and also the present hose with a protector is good in sealing property with the mating pipe and good in connecting function.
摘要:
A method for producing a multi-layered hose by electrostatically applying a thin resin layer on the inner surface of a tubular rubber outer layer. The resin can be applied by spraying resin powder from a bar nozzle inserted into an opening of the tubular outer layer, and the applied resin can be heated by an induction or dielectric heating source placed inside the tubular outer layer. The resin can be applied only to the hose body portion and not to edge portions which are to be attached to mating pipes, or a thinner layer of resin can be applied on the edge portions than on the body portion. An intermediate layer containing dielectric material or at least one of electrically conductive and magnetic material can be formed between the tubular outer layer and resin inner layer.

Disclosed is to provide a material which can withstand rapid increase in temperature to 1600° C. or more and exhibits little change in properties even in a high-speed combustion gas stream. Specifically disclosed is a SiC fiber-bonded ceramic coated with SiC, which is characterized by being produced by coating the surface of a SiC fiber-bonded ceramic with use of a coating layer including mainly SiC, wherein the SiC fiber-bonded ceramic includes inorganic fibers having a sintered SiC structure, each of which contains 0.01 to 1 wt % of oxygen (O) and at least one or more metal atoms of metal atoms in Groups 2A, 3A, and 3B and a 1-100 nm interfacial layer containing carbon (C) as a main component formed between the fibers.

A quick connector assembly includes a male member, a female member, and a retainer. The retainer is interposed between a ring-shaped projection of the male member and a first engagement portion of the female member to connect the male member and female member. When a worker holds operation end portions of the retainer with his or her fingers, the retainer is reduced diametrically so that a second engagement portion of the retainer disengages from the first engagement portion of the female member. Accordingly, the male member and retainer can be pulled off from the female member easily. The retainer holds the male member by fitting its aperture windows with the ring-shaped projection of the male member. Consequently, the retainer hardly falls down from the male member after it is removed from the female member. The male member can be removed sidewise through a substantially-letter-C-shaped opening of the retainer while diametrically enlarging a cross-sectionally substantially-letter-C-shaped body of the retainer. Thus, the retainer is deformed so less that it can be reused repeatedly a number of times.

Provided is a process for producing dense SiC fiber-bonded ceramics excellent in heat resistance and having a shape hard to form by hot pressing such as an elongated shape. The process for producing SiC fiber-bonded ceramics composed of: inorganic fiber made of SiC; and interfacial layers mainly made of carbon includes vacuum-sealing a preform, prepared by forming specific silicon carbide-based inorganic fiber into a certain shape, into a capsule and hot-isostatic-pressing the preform. The process is characterized in that the ratio of the number of carbon atoms to the number of silicon atoms in the preform is 1.02 to 1.20, and before the hot isostatic pressing, the preform is heated in an inert gas atmosphere or a reducing gas atmosphere at a temperature of 1200° C. to 1800° C. to adjust the oxygen content in the inorganic fiber to 6.0% by weight or lower, and then the hot isostatic pressing is carried out.

A quick connector includes a male member, a female member and an engager claw member. The male member includes a ring-shaped engager. The female member includes a receiver hole having an opening into which the male member is inserted, a ring-shaped stopper surface disposed oppositely to the opening, and a regulatory inner peripheral surface extending from the periphery of the stopper surface in an axial direction. The engager claw member disposed in the receiver hole of the female member, and it includes a ring-shaped base disposed movably in an axial direction, arms extending from the base to the opening in an axial direction and adapted for being elastically deformable in a radial direction, and a claw disposed so as to extend from each of the arms and adapted for engaging with the engager of the male member. In operation, the claws of the engager claw member are brought into contact with the stopper surface and engaged with the regulatory inner peripheral surface while they are engaged with the engager of the male member. Consequently, the male member in inhibited from displacing not only in an axial direction by the stopper surface, but also in a centrifugal direction by the regulatory inner peripheral surface. Thus, the engaging force associated with the claws is exerted securely, and accordingly the reliability of the quick connector in piping can be improved.
