    摘要: A method of controlling deflection of a charged particle beam in an electrostatic lens includes establishing a symmetrical electrostatic lens configuration comprising a plurality of electrodes disposed at unadjusted positions that are symmetric with respect to the central ray trajectory with applied unadjusted voltages that create fields symmetric with respect to the central ray trajectory. A symmetric electric field is calculated corresponding to the set of unadjusted voltages. A plurality of lower electrodes is arranged at adjusted positions that are asymmetric with respect to the central ray trajectory. A set of adjusted voltages is obtained for the plurality of lower electrodes, wherein the set of adjusted voltages corresponds to a set of respective potentials of the symmetric electric field at respective adjusted asymmetric positions. The adjusted voltages are applied to the asymmetric lens configuration when the charged particle beam passes therethrough.

    摘要: A removable belt-backing mechanism (50) is provided for a hand-held endless loop belt sander (2). The belt-backing mechanism (50) includes an attachment bracket (52), which slidably cooperates with a pair of slots (66, 68) to provide a removable connection to the sander. A plate (70) is movably connected to the attachment bracket (52) by a set of pins (72, 74, 76, 78), and is biased toward the inside surface of the sanding belt (26) by a set of springs (96, 98) to provide a flat sanding area for sanding planar surfaces.

    摘要: A belt sander attachment (2) is disclosed for a portable drill or the like (4), for sanding curved or flat surfaces. A frame (6) has a drive roller (8) and an idle roller (10) mounted thereto together with a movable carriage (22) carrying a second idle roller (24). The attachment includes belt changing locking means (78) for holding the carriage in a retracted position against the bias of belt tensioning biasing springs (32, 34). A positive belt tracking system (40) is provided for laterally adjusting the carriage relative to longitudinal belt movement around the rollers, to enable proper alignment and positive tracking under differing conditions. A belt tracking tray (70) is mounted to the carriage. A combined guard plate and pressure guide (54) enables guidance and application of sanding pressure by the user in a convenient orientation.
