A reader device of a location determination system gradually changes a transmission power step by step and repeatedly sends an interrogation signal which contains therein information on a power level indicating the transmission power. A tag of the location determination system receives the interrogation signal, sends a response signal into which the information on the power level contained in the interrogation signal is incorporated. The reader device receives the response signal and sends, to a management device, the information on the power level contained in the response signal and identification information for identifying the subject reader device. The management device detects the position of the tag based on the information on the power level and the identification information thus received.

When using a moving magnet type linear motor pair for a moving stage, the magnetic field in a space defined by the linear motor pair varies greatly in association with the movement of movable bodies. For this reason, 4N sets (N is a natural number) of magnet pairs 12 are disposed in mirror symmetry with reference to the center plane of a movable body 3 for a linear motor. The magnet pairs 12 are arranged in such a manner that the polarities of the adjoining pair at the center line 19 of the movable body are set same and the polarities thereof are set to alternate as in an N pole and a S pole according to when the pairs move away from the center. When a linear motor pair is formed by disposing two sets of such linear motors in parallel, and with this linear motor pair a stage is driven, the magnetic field variation in the space defined by the linear motor pair caused in association with the movement of movable bodies is suppressed. When such linear motor pair is utilized in a moving stage, for example, for an electron microscope and the like, a highly accurate electron beam image is observable.
