A rotary connector includes a case, a cover, a rotor having a top panel part and a first cylindrical part, a rotor snap having locking parts locked with an outer surface of the cover and a second cylindrical part snap-fitted to the first cylindrical part, flexible cables wound windably / rewindably in the case, and a ring-shaped plate part. In this case, a holding projection project outward in a radial direction from the outer circumferential surface of the second cylindrical part between a lower end of the first cylindrical part and the locking parts, and an inner rim of the cover is provided with a holding step so as to form a step. Furthermore, a wall surface forming the step of the holding step faces side surface of the holding projection, and an inner rim of the cover is rotatably interposed between lower surface of the holding projection and an upper surface of the ring-shaped plate part.

A slide fastener stringer easily manufactured by a series of manufacturing steps with molding fastener elements in a warp yarn exclusion area formed on one side edge of a fastener tape, wherein a fastener tape is produced by weaving with warp yarns and weft yarns of synthetic fiber yarn; plural pieces of water soluble fiber yarns are disposed inside over plural pieces of the warp yarns from the side edge of the tape; in a dying step in a process for manufacturing a fastener stringer, the water soluble fiber yarns are dissolved to form the warp yarn exclusion area; and by molding the fastener elements by using the warp yarn exclusion area, the fastener stringer is manufactured in an easy sequential manufacturing process without applying any special processing.

A multilayer orthotic / orthosis has a cover layer, a shell layer and a posting layer. The shell layer is formed of a thermoplastic having a moldable temperature. The rigidity of the shell layer, and in particular the rigidity of the thermoplastic is chosen to be of a magnitude to support the portion of the individual at temperatures below the moldable temperature. The shell layer, preferably the thermoplastic, has a flexibility above the moldable temperature to mold the shell layer into a shape to support the portion of the individual. The shell layer has two layers of woven polyester fibers (“scrim”) on the top and bottom. The scrim gives the plastic strength and prevents it from stretching excessively when molding. These unique properties make the material well suited for stacking multiple layers without having excessive bulking of material top lines. Both sides of the shell layer are coated with a layer of hot melt cement / glue / adhesive for easy attachment of various layers or other materials. One side of the shell layer is connected to one side of the cover layer. A posting layer is arranged on a side of the shell layer diametrically opposite the cover layer, and provides support for the orthotic / orthosis in order to prevent rocking, especially when the orthotic / orthosis is for the foot of the individual.

The invention discloses a mold-assembling tooling for a turbine guider single-blade wax mold, which comprises a wax mold fitted between an inner positioning block and an outer positioning block, the inner positioning block and the outer positioning block are installed on a track base, And it can move horizontally relative to the track base to clamp, position and release the wax mold; the non-clamping ends of the inner and outer positioning blocks are connected with the elastic mechanism to realize the inner and outer positioning blocks The elastic clamping and reset of the track base; the lower end of the track base is equipped with a rotating handle, which can rotate around the axis; the track base is equipped with an ejection structure that can move up and down. The structure is in contact with the inner positioning block and the outer positioning block in the form of an inclined surface, and the ejection structure and the rotating handle are in contact with a helical surface, and the ejecting structure moves up and down under the rotation of the rotating handle. The mold set tool can accurately and efficiently combine a group of individual blade wax patterns into a full ring guide wax pattern.

A method of molding a minute shape, in which at least one of a pair of dies is provided with an uneven section of a minute shape on a molding surface thereof, clamping of the pair of dies is stopped immediately before the dies are completely clamped, a resin is injected into a cavity, and thereafter the dies are completely clamped to thereby transcribe the shape of the uneven section onto the resin includes preparing a plurality of transcription dies each provided with the uneven section on a molding surface thereof, heating one of the transcription dies which is not used to mold a product by a heating unit, and exchanging the transcription dies with each other, at a point in time at which molding is completed, to thereby mold the product continuously.
