    • Disclosed is a hot air welder that consecutively joins sheets of synthetic resin material together to make a large-sized pavilion or a tent fabric, or welds and seals the seam lines of waterproof textiles or the like for waterproofing process. Instead of the conventional table-shaped body, there are provided an upright-standing drive body; hot-air welding means on an upper-side of the drive body; upper and lower drive rollers under the welding means, and wherein the welding work is performed by rotating and using alternatively the upper drive roller or the lower drive roller, according to the kind of fabrics to be welded and the work-substances. Therefore the heat welding and waterproofing process may be performed more easily for more various shaped work-substances, and that the troublesome work-substances such as sleeve or shoulder parts of waterproof clothes that have various positioned and shaped seam lines may be moved and rotated easily by the worker to be heat-welded and become waterproofed.
    • 公开了一种将合成树脂材料片连续地连接在一起以形成大型亭子或帐篷织物的热风焊机,或者对防水纺织品等的接缝线进行防水处理。 代替传统的台式体,设置有直立的驱动体; 热空气焊接装置在驱动体的上侧; 在焊接装置下方的上下驱动辊,并且其中通过根据待焊接的织物的种类和工作物质轮换和使用上驱动辊或下驱动辊进行焊接作业。 因此,对于更多种形状的工作物质,可以更容易地进行热焊接和防水处理,并且可以容易地移动和旋转诸如具有各种定位和成形的接缝线的防水衣物的套筒或肩部的麻烦的工作物质 由工人进行热焊接并变得防水。

    • A core for use in a slot type optical cable has one or more regularly disposed slots. One or more ribbon fibers are stacked into each of the slots, each of the ribbon fibers having a plurality of optical fibers. A tensile strength member is disposed at a center of the core. Each of the slots has a convex bottom surface with a predetermined curvature so that voids between the ribbon fiber at the bottom of the stack and top of the convex bottom surface in each of the slots are formed on both sides of the convex bottom surface. The convex bottom surface is provided with curvature whose radius is equal to or less than a distance from the center of the core to edges defined by the convex bottom surface meeting the pair of side surfaces in each of the slots.
    • 用于插槽型光缆的核心具有一个或多个规则设置的槽。 一个或多个带状光纤被堆叠到每个槽中,每个带状光纤具有多个光纤。 拉伸强度构件设置在芯的中心。 每个槽具有凸起的底部表面,具有预定的曲率,使得堆叠底部的带状纤维与每个槽中的凸形底表面的顶部之间的空隙形成在凸底表面的两侧上。 凸的底面设置有半径等于或小于从芯的中心到在每个狭槽中与一对侧表面相遇的凸底面限定的边缘的距离的曲率。
