摘要： A method and apparatus for dry cleaning a semiconductor wafer storage and transport pod. After the pod is located with respect to the cleaning chamber and opened to expose the interior surfaces of the pod to the cleaning chamber, the pod is conditioned in preparation for the cleaning process. The conditioning of the pod includes purging the pod and cleaning chamber with an ionized nitrogen gas to rid the pod and cleaning chamber of airborne contaminants and to neutralize static electrical charges on the pod surfaces. The conditioning process further includes heating the pod surfaces to prevent condensation of moisture and organic contaminants thereon. After the conditioning process, the pod is cleaned with a dry aerosol sprayed onto the pod surfaces. The aerosol spray is comprised of an ionized carbon dioxide/nitrogen (CO.sub.2 /N.sub.2) gas and fine particles of CO.sub.2. The dry cleaning apparatus further includes a circulation subsystem for circulating a fluid through the pod and cleaning chamber to remove airborne particulate, such as those dislodged from the pod surfaces by the CO.sub.2 /N.sub.2 aerosol spray. A filter provided within the path of the circulating fluid removes particulates from the circulating fluid.
摘要翻译：一种用于干燥半导体晶片存储和运输盒的方法和装置。在容器相对于清洁室定位并打开以将容器的内表面暴露于清洁室之后，调节容器以准备清洁过程。荚的调理包括用离子化氮气吹扫荚果和清洁室，以使荚果和清洁室中的空气污染物排出并中和荚果表面上的静电。调理过程还包括加热荚表面以防止其上的水分和有机污染物的冷凝。在调理过程之后，将荚用干燥的气雾剂喷洒到荚果表面上。气溶胶喷雾由电离二氧化碳/氮（CO2 / N2）气体和二氧化碳细颗粒组成。干洗设备还包括一个循环子系统，用于使流体通过荚和清洁室循环，以除去空气中的颗粒，例如通过CO 2 / N 2气溶胶喷雾从荚果表面移出的颗粒。设置在循环流体的路径内的过滤器从循环流体中除去微粒。

摘要： A detoning cleaner subsystem for a xerographic machine includes a housing having a longitudinal opening extending on one side thereof and a longitudinally extending rotating brush located therein which cleans toner particles from a moving photoreceptor surface moving past the opening. A longitudinally extending air manifold is located within the housing substantially adjacent the longitudinal opening, near one of first and second air gaps located between the photoreceptor surface and the manifold. The air manifold defines an air channel extending longitudinally substantially the length of the brush. The air channel is in communication with the longitudinal opening. A vacuum source in communication with the air channel provides a longitudinal air flow therethrough for maintaining the dispersed particles aloft and removing the particles. A flicker bar is preferably located between the brush and the air manifold to remove toner accumulation from the brush.

摘要： An apparatus which cleans a moving imaging surface with a cleaning blade and automatically detects a failure of the cleaning blade. A failure sensing mechanism detects the cleaning blade failure and activates a blade indexing mechanism. The indexing mechanism removes the failed cleaning blade and positions a new cleaning blade in a wiping or doctoring mode frictional contact with the imaging surface for cleaning. A brush positioned upstream of the cleaning blade, in the direction of movement of the imaging surface, disturbs the particles thereon.

摘要： A cleaning brush electrically biased with an alternating current removes discharged particles from an imaging surface. The particles on the imaging surface are discharged by a corona generating device. A second cleaning device including an insulative brush, a conductive brush or a blade, located upstream of the first mentioned brush, in the direction of movement of the imaging surface, further removes redeposited particles therefrom.

摘要： An insulative belt having a conductive pattern. A potential difference is applied to the conductive pattern on the insulative belt creating an attractive force that is exerted on the small particles of paper debris. This attractive force holds the paper fibers and paper dust on the insulative belt for subsequent removal, while allowing the cleaned paper sheet to move on through the electrophotographic system.
