Abstract: A pressure control valve has: a passageway having a flow opening; an member displaceable relative to the opening for obstructing the opening by differing amounts; a piezo actuator; and a linkage mechanism adapted to amplify a dimensional change in the piezo actuator and to use the amplified dimensional change to displace the member relative to the opening, wherein the linkage mechanism comprises a frame attached to a wall and fixed at a first end in relation to the passageway, a portion of the frame moveable in a first direction while being substantially restrained in a second direction orthogonal to the first direction, the piezo actuator extending between the wall and the movable portion such that an expansion of the piezo actuator results in movement of the movable portion in the first direction by an amount greater than the expansion of the piezo actuator, the moveable portion connected to the member.

Abstract: A system for positioning, a stage system, a lithographic apparatus, a method for positioning and a method for manufacturing a device in which use is made of a stage system that includes a plurality of gas bearing devices. Each gas bearing device includes: a gas bearing body, which has a free surface, a primary channel which extends through the gas bearing body and has an inlet opening in the free surface, a secondary channel system which extends through the gas bearing body and which has a plurality of discharge openings in the free surface. The flow resistance in the secondary channel system is higher than the flow resistance in the primary channel.

Abstract: A system for positioning, a stage system, a lithographic apparatus, a method for positioning and a method for manufacturing a device in which use is made of a stage system. The stage system has a plurality of air bearing devices. Each air bearing device has: a gas bearing body which has a free surface, a primary channel which extends through the bearing body and has an inlet opening in the free surface, and a secondary channel system which extends through the bearing body and which has a plurality of discharge openings in the free surface. The flow resistance in the secondary channel system can be higher than the flow resistance in the primary channel.
