    • The invention concerns improvements in a hammer-activated, powder-actuated drive tool comprising an elongated tubular housing, a tubular piston guide telescopically received extending from the front end of the housing, a piston telescopically movable within the piston guide, a chamber secured to the rear end of the piston guide for mounting a power load therein, and an activating assembly mounted on the tubular housing rearwardly of the chamber and comprising an elongate member slidably mounted relative to the housing and having a rear end extending outwardly of the housing at the rear end thereof and a forward end extending within the housing for contact with a power load mounted within the chamber. One improvement comprises providing the tubular housing with an internal bushing for slidably mounting the elongate activating member formed as a one-piece integrally molded member which experiences substantially no mechanical loading due to the activation of the power load. A further improvement comprises the provision of a retaining member for retaining a power load within the chamber without regard for the orientation of the tool, when the piston guide is in a retracted position. Yet a further improvement comprises a combined piston guide frictional engagement and retaining and piston resetting means mounted to the tubular housing for frictional engagement and retaining engagement with the piston guide and for engagement with the piston for effecting resetting motion thereof relative to the piston guide.
    • 本发明涉及一种锤击活化的粉末驱动的驱动工具的改进,其包括细长的管状壳体,从壳体的前端延伸伸缩的管状活塞导向件,可活塞地在活塞导向件内移动的活塞, 活塞引导件的后端,用于在其中安装动力负载;以及启动组件,其安装在所述管状壳体的所述腔室的后方,并且包括可相对于所述壳体可滑动地安装的细长构件,并且具有在所述壳体的后部向外延伸的后端 其端部在壳体内延伸以与安装在腔室内的动力负载接触。 一个改进包括为管状壳体提供内部衬套,用于可滑动地安装形成为一体式模制构件的细长致动构件,其由于功率负载的激活而基本上不受机械负载的影响。 进一步的改进包括提供保持构件,用于当活塞导向件处于缩回位置时,保持在腔室内的动力负载而不考虑工具的定向。 另外的改进包括组合的活塞导向器摩擦接合以及安装到管状壳体上的保持和活塞复位装置,用于与活塞导向件摩擦接合和保持接合,并与活塞接合以实现其相对于活塞导向件的复位运动。

    • A configuration of at least two TSOP memory chip housings stacked one on another, is described. Each of the TSOP memory chip housings has at least one memory chip with a number of pins disposed in an interior of the TSOP memory chip housing. The pins leading out of a respective TSOP memory chip housing and, via a rewiring configuration, are connected to pins leading out of a respectively directly adjacent TSOP memory chip housing of the same TSOP memory chip housing stack. In order to be able to produce such a housing stack as cost-effectively and simply as possible by an automated mounting method, the rewiring configuration is implemented in the form of leadframes respectively disposed between or at the side between the individual TSOP memory chip housings.
    • 描述了彼此堆叠的至少两个TSOP存储器芯片外壳的配置。 每个TSOP存储器芯片外壳具有至少一个存储器芯片,其中多个引脚设置在TSOP存储器芯片壳体的内部。 从相应的TSOP存储器芯片壳体引出的引脚和经由重新布线配置的引脚连接到引导出相同TSOP存储器芯片外壳叠层的分别直接相邻的TSOP存储器芯片外壳的引脚。 为了能够通过自动安装方法以成本有效且简单的方式生产这种壳体叠层,重新布线配置以分别布置在单个TSOP存储器芯片壳体之间或侧面的引线框架的形式实现。
