A fiber cable adapter comprises adjacent rows of fibers, each beginning with a set of fibers comprising a fiber pair, which comprises a transmitting fiber adjacent a receiving fiber, and a spare fiber adjacent the fiber pair. The spare fiber immediately precedes the fiber pair in one of the rows and immediately proceeds the fiber pair in the other row. A fiber cable cassette comprises an adapter panel supporting the fiber cable adapter. An integrated fiber cable management system comprises a fitting having a body with a collet through which a cable passes. A lock nut is threaded on a first end of the body to hold the body in relation to a chassis. A sealing nut is threaded on a second end of the body to tighten the collet on the cable to hold the cable in place in relation to the chassis. A flexible protector extends from the sealing nut to control the bend of the cable between the chassis and a fiber cable cassette. The flexible protector restricts the bend of the cable and thus extends the life of the cable.

The sole structure 1 has an upper plate, a lower midsole located under and fixedly attached to the upper plate, and having a laterally extending groove opening to the bottom side of the lower midsole, and a bending restriction member formed in a bent shape and spanning the groove longitudinally between the front edge and the rear edge of the opening of the groove. During the beginning phase of sole bending, the bending restriction member allows for the sole to bend till the bending restriction member gradually extends toward a straight shape from the bent shape and becomes taut between the front edge and the rear edge of the opening of the groove. During the advanced phase of the sole bending, when the bending restriction member experiences a force from the taut state, it functions so as to restrict the sole from bending.

A method of manufacturing a semiconductor mounting board includes providing a base member and linear conductive members formed of metallic wires. The conductive members are constructed so that they extend linearly between a semiconductor element-mounting face and a circuit board-mounting face of a base member, and are integrally molded within the base member. For this purpose, a resin material for forming the base member is injected into a mold wherein the conductive members are linearly arranged beforehand.

An ink jet printer includes an ink container supplying ink through a tube member to a separate print head to form an image. The ink jet printer also includes a guide rail to guide the print head, a transport roller to feed the recording medium, and a cover to prevent the tube member from contacting the roller. As the print head reciprocates in a width direction of a recording medium, the tube protruding from a surface of the print head on an end side in a moving direction thereof bends or flexes when the print head moves together with a carriage. The bending of the tube in the rearward direction is restricted by a tube band contacting the transport roller and cover. The cover and guide rail form a plane vertical to a platen at front faces of the cover and the guide. When the bending or movement of the tube is blocked or restricted by the vertical plane to a tube bending direction, the tube is not raised. Therefore, a resistance is not applied to the print head during the movement of the print head. Thus, the bending or movement of the tube can be restricted without providing a special device for the ink jet printer.

A lithographic projection apparatus includes a conduit that supplies utilities to a movable component in a vacuum chamber such as an object table, associated motor or sensor. The conduit comprises flexible metal bellows preventing out-gassing of the conduit due to the vacuum in the vacuum chamber while allowing movement of the movable component in at least a first degree of freedom.

A pig towing device is adapted for movement through a conduit having bends and open T intersections. The pig has a front leading cup and a rear trailing cup adapted to seal with the conduit for propelling the device through the conduit. The leading and trailing cups are spaced apart a predetermined distance to maintain the seal with the conduit as the pig towing device negotiates past the open T intersections. The pig towing device has a flexible body interconnecting the front leading cup and the rear trailing cup. The flexible body is urged normally into a straight position extending along a central axis thereof to maintain the front leading cup and the rear trailing cup spaced apart by the predetermined distance. The flexible body has predetermined limited flexibility permitting it to bend relative to the central axis as the pig towing device negotiates through the bends in the conduit.

The invention relates to a pipe structure (10) comprising a length of a flexible pipe connected to an end fitting, the flexible pipe comprising an armour layer (11; 19) and an underlying pipe layer (12; 11) to said armour layer, said underlying pipe layer having an outer surface around which armouring wires (111; 191) of an armouring layer are helically wound. The object of the present invention is to provide a coupling between a flexible pipe comprising armouring wires and an end fitting, the coupling exerting a relatively low bending or flexure strain on the wires during normal operation of the flexible pipe. The problem is solved in that the transition path of an armouring wire between the flexible pipe and the end fitting comprises an straight-line-section (194) between a wire-pipe-exit-point (195) where the wire extends away from its underlying pipe layer and a straight-line-end-point (196) on a support unit (15) of the end fitting where the armouring wire in question has its first tangential point of contact. This ahs the advantage that in a loaded situation where the armouring wires will elongate elastically leading to a change in the helical angle of the armouring wires, a pipe structure according to the invention will experience a slight twist and a controlled bending of the armouring wires on the surface of the support unit (due to a possible change in the base point of contact of the armouring wire with the support unit induced by the change of helical angle), thereby avoiding substantial bending of the individual armouring wires, which is of particular importance when the armouring wires are formed of a composite material. The invention may be used in flexible pipes for the off shore transport of fluids (e.g. oil).
