Abstract: A mechanical maneuvering system is configured to move an appendage in a first polar direction and a second polar direction. The mechanical maneuvering system has a housing base configured to accommodate a first bracket and a second bracket. A housing top is connected to the housing base and configured to accommodate a third bracket and a fourth bracket. A slide anchor is connected to each bracket and a different wire. Moving a first slide anchor in a first direction manipulates the appendage clockwise in the first polar direction. Moving a second slide anchor in a second direction manipulates the appendage counterclockwise in the first polar direction. Moving a third slide anchor in the third direction moves the appendage clockwise in the second polar direction. Moving a fourth slide anchor in a fourth direction manipulates the appendage counterclockwise in the second polar direction.

Abstract: A movable operation unit is movable on a two-dimensional operation surface of a main body. The two-dimensional operation surface is defined by an X-axis and a Y-axis perpendicular to each other. A Y-axis movable portion is rotatable around a rotation axis. The Y-axis movable portion is movable in the Y-axis direction when rotating around the rotation axis. The rotation axis extends in the X-axis direction relative to the main body. The Y-axis movable portion includes a sliding rail portion on which the movable operation unit is slidable in the X-axis direction. The movable operation unit is operable to slide in the X axial direction and move in the Y axial direction accompanied with rotation of the Y-axis movable portion around the rotation axis to performs a parallel shift in the two dimensional direction while regularly and constantly maintaining a posture of the movable operation unit.

Abstract: A manually operated driver for precision support stages having coarse and optional fine position control. A yoke connected to a movable stage slides along a shaft parallel to the direction of motion of the stage. The yoke has opposing pivot members that can, in one position, contact the shaft to self-lock the position of the yoke on the shaft and, in another position, remain clear of the shaft thereby allowing the yoke to slide freely on the shaft for coarse position control. The shaft has threads at one end that turn into a support block. Turning of the shaft with a knob and with the yoke locked to the shaft, slowly changes the position of the yoke and the connected stage for fine position adjustment of the stage. A pair of such drivers in orthogonal orientation on parallel x-y movable stages will provide two dimensional motion of stages.

Between the stationary base plate (12) and the upper movable platform (28) are positionally attached six strut assemblies (50). The six strut assemblies operate a hexapod that include in combination, a counterbalance subassembly (111), a servo motor subassembly (134), a bearing and encoder subassembly (156) and an electronics circuit (190). The combination accurately and repeatably positions the upper movable platform (28) within six degrees of freedom relative to the base plate (12).

Abstract: A single rotational axis motion generation and positioning apparatus having a work load support connected to a housing by a pivot joint. Rotation of an axial cam supported by the housing, creates a displacement which is transmitted to the work load support by at least one axial cam follower. The axial cam follower displacement is transformed into a rotational torque on the work load support about the pivot joint, which results in rotation of the work load support about the rotational axis of the pivot joint.

This working portion is mounted on the second slide that has two contacting portions. The driving portion is mounted on the base. When the driving portion drives the driving shaft rotating, the first cam and the second cam rotate accordingly and makes the working portion generating a special path. It can generate a constant-speed circular movement. It is easy to control. In addition, its volume is small.

The apparatus can be configured to include a bottom channel mounted to a base and a PCB tray mounted to a top channel, the PCB tray and top channel vertically adjustable from the base by a rotating shaft. The top and bottom channels are coupled to side bars and side channels in pairs movably connected by joint pins with a rotatable shaft movably connecting said joint pins. The sensing module is movable with respect to the base via rotation of said rotatable shaft causing movement of said pair of side bars and side channels, placing said sensing element nearest a target to obtain rotational movement data.

Abstract: An XY stage for precision movement for use in aligning a wafer in a microlithography system. A main stage supporting the wafer straddles a movable beam that is magnetically driven in a first linear direction in the XY plane. A follower stage, mechanically independent of the main stage, also moves in the first linear (X) direction and its motion is electronically synchronized by a control system with the main stage motion in the X direction. Electromagnetic drive motors include magnetic tracks mounted on the follower stage which cooperate with motor coils mounted on the edges of the main stage to move the main stage in a second linear (Y) direction normal to the X direction. Thus the main stage is isolated from mechanical disturbances in the XY plane since there is no mechanical connections and is lightened by removing the weight of the magnetic tracks from the beam.
