An optical subassembly (“OSA”) for use in optical communications modules is disclosed. The OSA solves various issues related to the insertion and removal of an optical fiber connector into and from the OSA receptacle, including hard plug, wiggle performance, and shavings production. In one embodiment, an optical communications module is disclosed and includes a housing and an optical subassembly of the present invention partially contained within the housing. The optical subassembly includes various components, including a body composed of a first material, and a plug receptacle formed with the body. The plug receptacle includes an inner surface on which surface features, such as threads, are formed. A hollow cylindrical sleeve composed of a second material is received in the plug receptacle such that the outer sleeve surface engages the surface features of the plug receptacle inner surface and such that an optical fiber connector can be received by the sleeve.

The invention relates to a shoe having a sole element. The sole element includes a sole area extending below a wearer's foot and a heel cup three-dimensionally encompassing a heel of the wearer's foot. The heel cup alone forms at least a portion of a sidewall of the shoe.

A cable carrier (10) has top (18) and bottom (16) longitudinally continuous sides, with one side (18) more flexible and the opposite side (16) less flexible. The sides are made of continuous sheets of material to define a closed tubular shape in which energy carriers can be housed and supported. The sheets may be integral, or have integral parts, and can be extruded. The carrier may be longitudinally openable with a zipper structure (125) to permit loading of energy carriers.

The invention discloses a vehicle-used slowly-springback polyurethane foam composite material which is compounded from slowly-springback polyurethane foam and an ethylene-vinyl acetate copolymer. The slowly-springback polyurethane foam is prepared from following components including, by weight, an A material: 40-80 parts of a polyether polyol 1421, 5-40 parts of a polyether polyol 2000D, 5-40 parts of a polyether polyol POP-36 / 28, 0.5-5 parts of diethanolamine, 1-6 parts of water, 0.1-1.5 parts of a catalyst EF-600, 0.1-0.5 parts of a catalyst ZF-10 and 1-6 parts of a silicone oil L-580; a B material: 40-80 parts of a modified MDI. During preparation of the slowly-springback polyurethane foam, a weight usage amount ratio of the A material to the B material is 100:40-80. The vehicle-used slowly-springback polyurethane foam is high in reaction activity, is low in toxicity, is environmental-protective, is high in damp loss factor, is high in sound-insulation performance and is free of addition of a foam-forming agent.

The invention provides cigarette aluminum-foil paper with an anti-counterfeiting label. The cigarette aluminum-foil paper comprises liner paper and an aluminum foil layer. An anti-counterfeiting laser film is arranged on the surface of the aluminum foil layer. The manufacturing process comprises the steps that the laser film is manufactured, an aluminum foil body coated with glue is heated and baked, the laser film and the aluminum foil are composited, a BOPP film is stripped from a cured semi-finished product, a BOPP base film on a cooled composited film is removed, a complexing agent for connecting the liner paper and the aluminum foil layer is prepared, and finally the liner paper and the aluminum foil layer are composited. The BOPP base film has the good temperature resistance and ageing resistance, materials are soft, no transparent de-bonding layer needs to coat the materials, and the technological process is simple; the anti-counterfeiting film is transferred onto aluminum foil, laser patterns will not disappear and are not likely to be damaged, and the while film is good in high temperature resistance and will not crack. The complexing agent between the liner paper and the aluminum foil layer is not likely to volatilize to generate hazardous substances, the temperature is high, and adhesive force can be provided for the liner paper and the aluminum foil layer for a long time.

The invention discloses to a fan clutch with magnetic rheologic fluid, comprising active plate, passive plate, magnetic rheologic fluid, drive shaft, excitation coil, bearing and sealing device. Drive shaft is connected with active plate set in hollow cavity of passive plate. Passive plate is divided into frontal and rear shell. Sealing cover, excitation coil and outer ring of clutch are set orderly from inner to outer between frontal and rear shell. Rheologic fluid is injected into the cavity formed by active and passive plate and excitation coil supplies power by carbon brush assembled at the central axis of frontal shell. Drive shaft is connected with engine and passive plate is connected with fan. The invention is a circular clutch with magnetic rheologic fluid. The structure is very compact and it is applied in narrow space between cooling fan and water tank of engine. Rheologic fluid is flowing iteratively in the space between active and passive plate, which is advantaged to eliminate heat and prolongs the service life of rheologic fluid.

A two-layer external breast prosthesis comprising a first inner layer comprised of a self-shaping dispersion and a second outer layer comprised of an elastic material, wherein the second outer layer is relatively stiffer than the first inner layer.

The invention relates to a marine airbag type fast leak stopper. The marine airbag type fast leak stopper is characterized by comprising a composite airbag, an air intake control valve, an airbag fixing sleeve, an operation handle, a miniature high-pressure air storage steel cylinder and an air guide supporting rod, wherein the composite airbag is of a thin-wall double-layer composite structure composed of an inner seal bag body and an outer high-strength bag body, the bottom of the composite airbag is fixedly connected with the operation handle through the airbag fixing sleeve, the miniature high-pressure air storage steel cylinder is arranged in an inner cavity of the operation handle, the opening of the miniature high-pressure air storage steel cylinder is fixedly connected with the air intake control valve, and the upper end of the air intake control valve is connected with the air guide supporting rod. The marine airbag type fast leak stopper has the advantages that a wedge-shaped structure of the composite airbag is adopted, the leak stop size range is large, and hole adaptation capacity is high; conical sleeve type seal design is adopted, dual-stud locking is conducted, seal performance is guaranteed, and meanwhile dismounting is convenient; bangalore torpedo type operation design is adopted, operation is conducted through a stay cord, high-pressure air is released instantly, rapid air inflation is achieved, and rapid leak stop is achieved.

The invention provides a real-time detection method of orthodontic force of a bracket-free seamless appliance specific to real-time detection problem of orthodontic force of the bracket-free seamless appliance for stomatology. Aiming at the phenomenon that the orthodontic force of the seamless appliance for stomatology is small and the contact area and contact gap are small when the seamless appliance is worn on teeth surfaces, the real-time detection of the orthodontic force of the bracket-free seamless appliance can be realized by using the piezoresistive effect of a thin-film single-point sensor and the excellent physical properties such as small size, soft material and thinness of a sensor, and the stress variation trend of one tooth or an arbitrary part on multiple teeth can be detected according to research needs; and through research of acting force system and acting effect of the seamless appliance, an orthodontist formulates a relatively reasonable and effective therapeutic scheme, and a designer designs a relatively perfect individual seamless appliance; and the real-time detection method is high in detection accuracy, good in timeliness, simple and practicable in a detection process and low in cost.
