摘要： A ball-on-belt transport includes a belt with a steel ball positioned on top of the belt and a magnet on the back side of the belt with the ball forming a nip with the belt to provide necessary normal force against a conveyed sheet and thereby allowing easy lateral pulling of sheets in clearing jams from the nip. Alternatively, a steel ball is retained while in contact with a belt to apply a normal force to a sheet on the belt equal to the weight of the steel ball. The ball is encased in a housing that is surrounded by a solenoid coil such that when current is applied to the coil, it acts as a solenoid and raises the ball off the belt surface and thus releases the nip pressure.

摘要： A device for adding controlled amounts of moisture to one or both sides of a copy sheet. The device includes a pair of water jets, a reservoir for storing a quantity of liquid and connected to the water jet, a pair of generally cylindrical, pressure rolls, each having an outer cylindrical surface with the rolls being aligned with respect to one another along their axes so as to define a nip between the outer cylindrical surfaces, and a controller for controlling application of water from the water jets to selected portions of each sheet passing thereunder before each sheet enters the nip formed between the outer cylindrical surfaces. Alternatively, the water jets could apply the liquid to the cylindrical surfaces of the pressure rolls.

摘要： A sheet stacking and registration system particularly suited for high speed sequentially stacking of the flimsy printed sheets output of a high speed reproduction apparatus in a sheet stacking area, with a stacking registration position; with a vacuum belt sheet transport system acquiring only a limited lead edge area of the sheets and transporting them over the stacking area with non-slip sheet feeding towards the registration position; and an integral system peeling the lead edges of the sheets off of the vacuum transport and guiding them downwardly and towards the lead edge registration position while reducing but partially maintaining the sheet's vacuum acquisition, and applying a normal force, preferably with a roller pressing down the lead edges of the peeled off sheet against the previously stacked sheets adjacent the registration position, to frictionally slow the sheet as it approaches the registration position, and also holding down the sheet after it reaches the stacking position. The sheet transport may have spaced belt flights with spaced patterns of vacuum apertures spaced between substantially unapertured areas along the belts, and a synchronized belt drive to synchronously engage the lead edge areas of the incoming sheets. An upstream natural arcuate inversion path with a side registration system may be integrated therewith.

摘要： A lead frame having a die thereon connects a conductive area on the die to a lead frame contact using a conductive clip that includes a structural portion that is received with a recess-like “tub” formed in the lead frame contact. The end of the clip received in the tub is held in place during subsequent handling by a solder paste deposit until the clip and leadframe undergo solder reflow to effect a reliable electrical connection. The effective surface area between one side of the clip and the other side of the clip within the tub is different so that the surface tension of the liquefied solder formed during the solder reflow step will “draw” the clip into a preferred alignment against a “stop” surface.
