    Abstract: A tare supporting apparatus supports the tare of a structure required to have very high surface precision, without affecting the surface precision of the structure. For that, the tare supporting apparatus comprises a driving unit for moving a driven body in the direction of gravity with respect to a base, and a supporting unit for supporting the tare of the driven body at a position after driven, wherein the driving unit and supporting unit are so arranged that a drive force of the driving unit and a support force of the supporting unit are on a same axis.

    Abstract: PROBLEM TO BE SOLVED: To efficiently remove heat from a linear motor coil without damaging protective film on the surface of the coil by providing a jacket with double structure composed of an inner jacket and an outer jacket and letting different types of coolants to flow through the inner jacket and the outer jacket of the coil. SOLUTION: A double jacket is constituted, for example, of a coil inner jacket 4 and 4' which embraces a coil 1 and is supplied in its internal space with a coolant and an outer jacket 9 and 9', which is supplied outside the jacket with coolant. Inert gas is let to flow through the coil inner jacket 4 and 4' so that the protective film on the coil is not damaged. A coolant, regardless of its being activated or inert, satisfactory in cooling efficiency is let to flow through the outer jacket 9 and 9'. Thus insufficiency in cooling capability due to adoption of an inert coolant inferior in cooling capability for the coil inner jacket 4 and 4' can be made up by letting coolant satisfactory in cooling efficiency flow through the jacket 9 and 9'.

    Abstract: PURPOSE: To prevent the deterioration in positioning accuracy that is caused by the temperature change. CONSTITUTION: A mobile stage 2 is moved by a lenear motor 3, and a laser interferometer 4 detects the present position of the stage 2 from the reflected light of a mirror 2a and feeds this detected position to a driver 3a of the motor 3. At the same time, the temperature of the stage 3 is detected by a temperature sensor 5 and this detection output is supplied to a computing element 5b. Then the change of distance between a positioning object matter W1 and the reflecting surface of the mirror 2a is calculated and supplied to the driver 3a to correct the driving value of the motor 3.

    Abstract: PURPOSE:To prevent the adverse influence given to the positioning accuracy due to the heating of a driving device by measuring the temperature of a driving means or the temperature of a place near the driving means at least at a single point and controlling the temperature of a refrigerant that is circulated by a cooling device based on the measured temperature. CONSTITUTION:A controller 14 gives a command to a driver 15 so that a positioning subject 10 is set at a prescribed position based on the position data on a position measurement means 12. Thus the driver 15 drives the driving means 1a and 1b. Under such conditions, the temperature varies if the means 1a and 1b generate the heat. A temperature measurement means 2 measures the temperature by a temperature sensor 5 placed at the means 1b (1a), and a temperature control means 4 controls the temperature of a refrigerant 3a that is circulated by a cooling device 6. Thus the temperature changes of both means 1a and 1b can be eliminated. Then the thermal deformation never occurs since the temperature change of the means 1b is eliminated. Therefore the change of distance is eliminated between the subject 10 and a position standard 11 and no error is caused in measurement of positions.
