摘要:
A stage apparatus includes a base having a reference surface, a moving unit which moves along the reference surface, a static bearing which is provided in the moving unit and which supports the moving unit such that the moving unit can move along the reference surface, and a temperature controller which is provided in the moving unit and which controls the temperature of gas supplied to the static bearing. In the stage apparatus, air fluctuation in the measurement area of interferometers due to gas exhausted from the static bearing and/or distortion caused by heat transmitted to a retainer of a target is suppressed, and the stage positioning accuracy is thereby increased.

This invention discloses an apparatus having a base and a movable body which is driven to move along the base. The apparatus includes a generator configured to generate a driving signal for the movable body, a temperature adjusting mechanism configured to adjust temperature of the base, and a controller configured to control a manipulated variable for the temperature control mechanism based on the generated driving signal.

A stage apparatus includes a base, a stage movable on the base in first and second directions, a first member movable relative to the base in the first direction, and a second member movable relative to the base in the second direction. The first member is placed on the second member. With this arrangement, drive reaction-forces generated due to movement of the stage can be canceled by moving the first and second members, resulting in a smaller space needed for accommodating a canceling mechanism.

This invention provides a cell switching apparatus having buffer memories in which accesses of a plurality off cells can be implemented in one-cell time. The cell switching apparatus arranges a plurality of buffer memories, in which accesses of a plurality of cells can be performed, in parallel, and schedules a score table so that the writing and reading out operations may not overlap. Accordingly, the incoming lines may be increased lip to (the number of incoming lines n)=(the number of buffer memories p-1).times.(the number of outgoing lines m) without increasing the access speed of the buffer memories.

A stage device includes a base, and a stage movable portion being movable along a surface of the base. An interferometer measures a position of the stage movable portion, and at least one of a piping element and a wiring element is connected to the stage movable portion. An auxiliary member holds the piping element or the wiring element. The auxiliary member surrounds at least a portion of the piping element or the wiring element and is flexible, to be bent in accordance with the bending of the piping element or the wiring element, and a heat insulating material, held by the auxiliary member, reduces heat to be transferred from the piping element or the wiring element to a space through which measurement light of the interferometer passes.

A moving element to be propelled across a stator includes a coil unit, including coils, for generating a force to propel the moving unit, and a cooling unit for cooling the coil unit. A thermal conductive member, arranged between the cooling unit and the coil unit, transmits heat away from the coil unit. In addition, a housing unit houses the coil unit, the cooling unit and the thermal conductive member.

A plane motor device that includes a stator unit, a movable unit movable along a plane above the stator unit, first and second coil units at one or both of the movable unit and the stator unit, in which coil units a current flows for driving the coil unit, and an enclosure partitioned into a plurality of separate regions. The enclosure encloses the first and second coil units in two respective regions of the plurality of separate regions. Each of the two regions has a cooling channel through which cooling refrigerant flows separately from the cooling channel of the other region.

A stage device includes a movable stage, a base which supports the stage, and a mass body which moves to cancel a reaction force acting on the base as the stage moves. The base has a plurality of surfaces, and the stage and mass body are supported by different ones of the surfaces of the base. In addition, when the mass body is arranged in the base, the stage device can be more downsized.

In an air conditioning apparatus of the separate-type, an indoor unit is mounted on a wall of a room. The indoor unit is provided with an infrared ray detection unit which has an infrared ray sensor for sensing infrared rays, a temperature sensor for sensing a temperature in the detection unit, and a slit window for restricting a field of view of the detection unit. The detection unit is horizontally swung with a discharge opening of the indoor unit, from which warm or cold air is discharged, so that the room is swept by the field of view and the air. The room temperature distribution is obtained from the output signal from the detection unit and, the amount of the discharged air directed to the respective areas of the room is adjusted in accordance with the room temperature distribution.
