    摘要: The mechanism includes a pair of gates which are horizontally spaced from one another and which are operable to stroke between inwardly extended and outwardly retracted positions for collecting and dropping the articles, respectively. The gates are mounted on a threaded member for selective horizontal adjustment of the distance between the gates to enable collection of articles of various widths. As an incident to adjusting the distance between the gates, the stroke of the gates is simultaneously adjusted.

    摘要: A device for sampling the surface of the skin includes a substrate having a light absorbing area disposed thereon. A layer of adhesive is disposed on the substrate overlying the light absorbing area. The adhesive layer is optically clear and under pressure conforms to the surface of the skin to be sampled. A removable protective film is disposed on the adhesive layer for protecting the adhesive layer prior to use of the device.

    摘要: The crystallographic plane-dependent, amphoteric nature of Si-doped AlGaAs is used to provide a low threshold semiconductor laser. An active layer of AlGaAs is sandwiched between an injection layer and a current confining layer of AlGaAs. The injection layer is doped to be n-type conductivity. The confining layer is amphoterically doped with Si to be n-type in a (100) plane and p-type in a (111)A plane. The resulting p-n junctions, heterostructure, and geometry provide the current and the optical confinement for the semiconductor laser.
