Abstract: The control assembly comprises a torque-restoring mechanism (13) with springs (20), a motion converting transmission with a multiplying gearing (56, 57) converting a rotation of the turnstile over 120° into a rotation of the rotary shaft entering the hydraulic damper (26) over 180°. The hydraulic damper (26) comprises two pistons mounted onto a single piston rod. A cam or crank mechanism converts a rotation of the rotary shaft entering the hydraulic damper over 180° into a reciprocating motion of the two pistons over two half stroke lengths. The first piston damps the rotary movement of the turnstile when moving in one direction whilst the other piston damps this movement when the pistons move in the other direction. The movement of the turnstile is thus damped in both of its rotation directions.

Abstract: An active rinse shield designed to protect electrofill chemical baths from excessive dilution during rinse sprays on the semiconductor wafer. The shield uses overlapping blades to cover the bath, making a physical barrier between the bath chemistry and the wafer rinse water. The blades are interconnecting ribs that actuate around a common pivot axis. A linear mechanical actuator controls the blade movement, moving the top-most blade, which in turn, moves an adjacent lower blade. Each upper blade is interconnected to an adjacent lower blade by upper and lower ledges, a pivot boss and interlocking cut, and a curved ledge on each blade's body surface. The interconnecting features allow the blades to move one another out for extension or in for retraction. The interlocking blades are inclined above one another, forming grooves to redirect the rinse water away from the chemical bath.
