Abstract: Methods and apparatus for ascertaining the end of an etch process while etching through a target layer on a substrate in a plasma processing system which employs an electrostatic chuck. The end of the etch process is ascertained by monitoring the electric potential of the substrate to detect a pattern indicative of the end of the etch process. By the way of example, changes to this potential may be observed by monitoring the current flowing to the pole of the electrostatic chuck. Upon ascertaining the pattern indicative of the end of the etch process, for example by monitoring the current signal, a control signal is produced to terminate the etch.

Abstract: A laminating apparatus includes a detector disposed between introduction-side transport rollers and a web supply unit. When the detector detects a front edge of a prior object transported by the introduction-side transport rollers, then the introduction-side transport rollers and a laminate processing unit transport and laminate the prior object until a rear edge of the prior object is positioned in the vicinity of the web supply unit, whereupon transport and lamination of the prior object are stopped for a predetermined duration- of time. Then once the detector detects a front edge of the subsequent object after the predetermined duration of time elapses from stopping transport of the prior objects the introduction-side transport rollers transport a subsequent object to the. laminate processing unit.

Abstract: The stock approach piping to a multi-layered headbox can be modified to include a dilution water header that independently supplies dilution water, such as whitewater, to multiple CD segments or zones of the tube bank which supply stock to each layer. The CD basis weight profile of the final sheet is monitored and, in response to the measured CD profile, dilution water flow is increased or decreased to those tube bank segments that need their consistency altered. By selectively controlling the basis weight of distinct segments of the CD profile for each layer, a more uniform sheet can be produced.

Abstract: A multi-piece crankshaft having a main shaft with two ends adapted to rotate about its axis. A crankpin also has two ends and an axis parallel to but radially spaced from the axis of the main shaft. At least one counterweight extends between one end of the shaft and one end of the crankpin and this counterweight is formed by casting a liquid metal around the ends of the main shaft and crankpin in a molding chamber.

Abstract: A tracked vehicle produces a pressure no more than 3 psi on the ground by increasing the number of contact points on the inner surface of the track. The stiffness of the track is also selected to minimize bowing between the idler wheels or rollers. The track is therefore kept substantially straight between the rollers so increase the efficiency associated with transferring power to track. The drive sprocket is positioned above the ground so as to eliminate complexity in the design and yet effectively transmit power to the tracks. Positioning the drive sprocket above ground also prevents derailing of the track. The track is also held in a constant state of tension on the driver sprocket and the roller. This too prevents derailment. The undercarriage of the vehicle includes torsion axles and sealed bearings to provide for a lower maintenance track. Components associated with the undercarriage do not require constant greasing and cleaning of the idler wheels.
