    摘要： A lead frame structure for a semiconductive device package is fabricated by laminating two preformed thin sheets, the lower sheet having a fully developed set of closely spaced inner lead tips and the upper sheet having leads which terminate short of the tips. The laminated lead frame has the thickness required for handling, assembly and use. The cavity formed by the foreshortened lead tips of the upper sheet is adopted to contain beam-lead or flip-chip devices bonded directly to the lead tips of the lower sheet. The very thin lower sheet makes possible closer lead spacing than was heretofore possible with either photoetching or stamping techniques.

    摘要翻译： 用于半导体器件封装的引线框架结构通过层压两个预制薄片来制造，下片具有完全展开的一组紧密间隔的内引线端，并且上片具有端部不足尖端的引线。 层压引线框架具有处理，组装和使用所需的厚度。 由上片的缩短的引线端形成的空腔用于包含直接结合在下片引线的引线或倒装芯片。 非常薄的下片使得可能比之前可能用光刻或冲压技术更紧密的引线间距。

    摘要： A method of manufacturing miniature potentiometer contact springs by winding a substantial length coil of a single layer of fine, heat-treatable precious metal alloy wire on a generally cylindrical form, masking spaced strips longitudinally of the wire coil, plating the wire coil between the masked strips, removing the strips and cutting the strip-plated wire band from the mandrel as a sheet, cutting the wire sheet to produce contact strip blanks of various forms severable into individual contacts. A multi-layer masking system is used to photographically define the spaced strips. An adherent support about the wire coil permits the coil to be removed before masking and processed in sheet form. Contact springs using wire of a reduced lateral diameter are produced by flattening the wire prior to winding on the form.

    摘要： A zip fastener chain comprised of a pair of stringer tapes of substantially endless length each having along their longitudinal edges alternate groups of fastener elements and element-free selvage portions. The groups of fastener elements are interconnected by a strip of water-soluble film, the arrangement being such that there may be provided a space or element-free portion on an individual fastener without having to remove those fastener elements off the tapes as in conventional practice.

    摘要翻译： 拉链链条由一对基本无环长度的纵梁组成，每条长条带沿其纵向边缘具有交替的紧固件元件组和无元件边缘部分。 紧固件元件组通过一层水溶性薄膜相互连接，其结构使得可以在单个紧固件上设置空间或无元件部分，而不需像传统实践那样将这些紧固件元件从带上拆下 。
