    • A turbine includes, in an exemplary embodiment, an outer housing, a turbine shaft rotatably supported in the outer housing, and a plurality of turbine stages located along the turbine shaft. Each turbine stage includes a diaphragm attached to the casing, a rotor having a plurality of buckets and a bucket cover fixedly attached to the turbine shaft, and a packing ring mounted in a first circumferentially extending groove in said diaphragm. The packing ring includes a seal shroud and a sealing means and is positioned adjacent the turbine shaft. The seal shroud is fabricated from a first material having a first coefficient of expansion, and the is diaphragm fabricated from a second material having a second coefficient of expansion. The first and second materials are selected so that at a first temperature a gap between the turbine shaft and the diaphragm is larger than at a second higher temperature.
    • 在示例性实施例中,涡轮机包括外壳,可旋转地支撑在外壳中的涡轮轴和沿涡轮轴定位的多个涡轮级。 每个涡轮级包括一个安装在壳体上的隔膜,具有多个铲斗的转子和固定在涡轮机轴上的铲斗盖,以及安装在所述隔膜中的第一周向延伸凹槽中的密封圈。 密封环包括密封罩和密封装置,并且邻近涡轮轴定位。 密封罩由具有第一膨胀系数的第一材料制成,并且是由具有第二膨胀系数的第二材料制成的隔膜。 选择第一和第二材料使得在第一温度下,涡轮轴和隔膜之间的间隙大于在第二较高温度下的间隙。

    • A stream class driver for use in a computer operating system functions together with a minidriver. The minidriver is associated with a particular design for an adapter, which is a hardware device that generates or receives streaming data. The stream class driver deals with common operating system tasks such as direct memory access, scatter/gather memory use and Plug n Play. The stream class driver is independent of the hardware design and can therefore function with any type of streaming device or external buses such as USB or IEEE 1394 the minidriver functionality is limited to only those functions required by the unique aspects of the hardware and for the minimum requirements of operation, thereby minimizing the complexity and burden of designing minidrivers for hardware devices.
    • 用于计算机操作系统的流类驱动程序与minidriver一起工作。 minidriver与适配器的特定设计相关联,适配器是生成或接收流数据的硬件设备。 流类驱动程序处理常见的操作系统任务,如直接内存访问,分散/收集内存使用和Plug n Play。 流类驱动程序独立于硬件设计,因此可以与任何类型的流设备或外部总线(如USB或IEEE 1394)配合使用,小型驱动器功能仅限于硬件的独特方面所需的功能,最低限度 操作要求,从而最大限度地减少了设计硬件设备的小型驱动程序的复杂性和负担。
