    • An electrostatic chuck is faced with a patterned silicon plate 11, createdy micromachining a silicon wafer, which is attached to a metallic base plate 13. Direct electrical contact between the chuck face 15 (patterned silicon plate's surface) and the silicon wafer 17 it is intended to hold is prevented by a pattern of flat-topped silicon dioxide islands 19 that protrude less than 5 micrometers from the otherwise flat surface of the chuck face 15. The islands 19 may be formed in any shape. Islands may be about 10 micrometers in diameter or width and spaced about 100 micrometers apart. One or more concentric rings formed around the periphery of the area between the chuck face 15 and wafer 17 contain a low-pressure helium thermal-contact gas used to assist heat removal during plasma etching of a silicon wafer held by the chuck. The islands 19 are tall enough and close enough together to prevent silicon-to-silicon electrical contact in the space between the islands, and the islands occupy only a small fraction of the total area of the chuck face 15, typically 0.5 to 5 percent. The pattern of the islands 19, together with at least one hole 12 bored through the silicon veneer into the base plate, will provide sufficient gas-flow space to allow the distribution of the helium thermal-contact gas.

    • A safety shield for containing and deflecting a fluid leaking from a flanged pipe coupling in the form of an arcuate strip of transparent fluoropolymer. The strip has a flange along each circumferential edge which is integral with the strip and extends radially inwardly thereof. The strip is of sufficient length to encase the circumference of the pipe coupling flange to which it is applied with the opposing ends overlapping and fastened together. The flanges closely engage the radial surfaces of the coupling flanges. The safety shield is obtained by heat-shrinking a heat-shrinkable tube of fluoropolymer while restricting radial shrinkage thereof except the marginal edge portions which become the flanges.
    • 用于容纳和偏转由透明含氟聚合物的弓形条形式的法兰管接头泄漏的流体的安全屏蔽。 该条具有沿着每个圆周边缘的凸缘,其与带材一体并且在径向向内延伸。 条带具有足够的长度以包围其所施加的管接头法兰的圆周,相对端重叠并紧固在一起。 凸缘紧密接合联接凸缘的径向表面。 通过将含氟聚合物的热收缩管热收缩而限制其径向收缩,除了成为凸缘的边缘部分之外,可以获得安全屏蔽。
