Abstract: A slide fastener for preventing core strings from being caught in a gap between upper and lower flanges, securing the flexibility of the slide fastener when engaged, and improving the designability of the slide fastener. The gap dimension between the upper and lower flanges of a slider in the up-down direction is smaller than the core string dimension in the front-rear direction when the core strings are pressed with the pressure of 5 kgf. Fastener elements are independently disposed in the up-down direction of a tape member when engaged. The fastener element has a design portion disposed at a front side of the tape member, and an engaging portion disposed at a rear side of the tape member so as to engage with adjacent fastener element, and the design portion is disposed distant from the adjacent design portion when engaged and having a hemispherical shape with a curved shape.

With this arrangement, when excessive lateral pulling force is applied to the slide fastener, cleavage lateral pulling force that causes cleavage of the slide fastener can be reduced. By adjusting tensile rupture strength of the elements, cleavage lateral pulling force of the slide fastener can be set within a predetermined range.

Abstract: In a reflective warp-knit tape, a narrow-width warp-knit tape is knitted of chain-stitch yarns, which form loops along longitudinal wales of the warp-knit tape, and weft inlaid yarns. And a reflective film is knitted in the warp-knit tape at a selected interwale space by the weft inlaid yarns and additional weft inlaid yarns. A heat-melting film also is knitted in the warp-knit tape at another selected interwale space by the weft inlaid yarns. Alternatively, the heat-melting film may be substituted by heat-melting yarns inlaid in the wales. In another alternative form, all the knitting yarns of the warp-knit tape may be thermoplastic resin monofilament yarns so that the light-reflecting function of the tape can be improved.

Abstract: Method of manufacturing, in one piece, forged connecting rods. The method includes cutting blanks from a bar. Each blank is worked in several steps, until it assumes its final shape. During the various working steps, a groove made in each blank is caused to spread out in a predetermined manner and finally forms a fracture initiation (44), in the area (38) through which bolt holes are drilled for the bearing cap mounting bolts. After final working, the remaining portions of the core portion (10, 46, 50) are divided by a slight separating force, thus providing in the fracture surface the required guidance for remounting the bearing cup on the upper bearing.

Abstract: A slide fastener which permits easy attachment of electric conductors and ensures supply of electric current to all metallic coupling elements even if a part of the electric conductors is cut off. And it has a neat appearance because the electric conductors exposed in spaces among the coupling elements do not look unsightly.

Abstract: The invention relates to a slide fastener, which is particularly well suited for ornamental purposes. The slide fastener comprises teeth, which are arranged in two juxtaposed rows so that each teeth is adapted to interlock with adjacent teeth of the opposite row. The slide fastener is adapted to be opened and closed by a slider. The slide fastener should have a high flexibility in conjunction with a higher stability and should be adapted to carry ornamental stones or to be used as an ornamental fastener in itself. Besides, the slide fasteners, with the exception of the slider, should be adapted to be made as an endless strip on a machine. And the slide fastener should be adapted to be used as an ornamental braid without a textile carrying strap. Such ornamental braid should have a slider for opening and closing the braid and for adjusting its length.
