    • A cryogenic valve includes a first port and a second port, a valve body, a valve stem, a sealing member, a valve element and a housing. The valve body includes a valve seat defining a fluid orifice in fluid communication with the first port. The valve stem is configured to engage with the valve body, wherein at least one of the valve stem and valve body form an inner valve cavity. The valve element is positioned within the inner valve cavity. The valve element is also configured to bias the sealing member against the orifice to substantially block flow through the orifice and the first port. The bias is controlled in response to control of the valve element by a valve actuator. A channel is configured to allow fluid flow through at least one of the valve stem and valve element along a longitudinal axis. A housing is configured to substantially seal and enclose at least a portion of the valve body and valve stem. The housing forms an inner housing cavity configured to thermally isolate the exterior of the valve body and valve stem from the housing.
    • 低温阀包括第一端口和第二端口,阀体,阀杆,密封构件,阀元件和壳体。 阀体包括限定与第一端口流体连通的流体孔口的阀座。 阀杆构造成与阀体接合,其中阀杆和阀体中的至少一个形成内阀腔。 阀元件位于内阀腔内。 阀元件还构造成将密封构件偏置抵靠孔口,以基本上阻挡通过孔口和第一端口的流动。 响应于通过阀致动器对阀元件的控制来控制偏压。 通道构造成允许流体沿着纵向轴线流过阀杆和阀元件中的至少一个。 壳体构造成基本上密封和封闭阀体和阀杆的至少一部分。 壳体形成内壳体空腔,其构造成将阀体的外部和阀杆与壳体隔离。

    • RF feedthroughs for use with monolithic microwave integrated circuits (MMIC) are installed in environmentally protective or hermetically sealed packages that provide electromagnetic shielding. A feedthrough for an MMIC package has a dielectric substrate, a microstrip or transmission line formed on the substrate for transmitting high frequency electronic signals and a wall disposed above the transmission line and the substrate. The wall of the feedthrough has a varying thickness so that the narrowest portion of the wall is disposed on the transmission line substantially perpendicular to the substrate. The transmission line also has a varying width so that the narrowest width portion of the transmission line crosses the narrowest portion of the wall. The narrowest portion of the wall may be created by placing two oppositely facing concaved surfaces on each side of the wall. To reduce parasitic capacitance, the substrate and the wall may each have an air cavity embedded in respective bodies.
    • 用于单片微波集成电路(MMIC)的RF馈通装置安装在提供电磁屏蔽的环境保护或密封封装中。 用于MMIC封装的馈通装置具有电介质基板,形成在用于传输高频电子信号的基板上的微带或传输线,以及设置在传输线和基板之上的壁。 馈通的壁具有变化的厚度,使得壁的最窄部分设置在基本上垂直于衬底的传输线上。 传输线还具有变化的宽度,使得传输线的最窄宽度部分与壁的最窄部分交叉。 壁的最窄部分可以通过在壁的每一侧上放置两个相对的凹面来产生。 为了减少寄生电容,衬底和壁可以各自具有嵌入相应体内的空气腔。
