Abstract: A luminance variation (dI) pertaining to each pixel is calculated (21) using a plurality of captured images obtained by image capturing under different illumination conditions, a texture variation (dF) pertaining to each pixel is calculated (22) using a plurality of captured images obtained by image capturing at different time points, and a subject region is extracted (23) based on the luminance variation (dI) and the texture variation (dF). A variation in the texture feature (F) pertaining to each pixel between the images is calculated as the texture variation (dF). The subject can be extracted with a high accuracy even when there are changes in the ambient light or the background.

Abstract: To increase the reliability of a non-contact IC card for use in such applications as a door key, etc., two separate combinations of an IC chip and an antenna coil coupled to that chip are provided in the card, with each IC chip storing the same information, such as a key code. Since the probability of both of the IC chips being damaged concurrently due to application of external force is very much smaller than the probability of failure of a single IC chip, the objective of enhanced reliability is effectively achieved.

Abstract: A distance between a mask and a wafer is set such that exposure light beams emerged from the mask are converged by the projection lens to be focused on the wafer. Two light beams with same wavelength of the alignment light beam emerge from a first point (b) which is located far away from the mask, and are focused on the wafer or neighborhood of it by the projection lens. Two mask marks of diffraction gratings are formed on the mask and spaced at a predetermined distance from each other. When the alignment light beams are applied to the mask marks, two diffracted light beams of predetermined order emerge individually from the mask marks in such a manner that the respective optical axes of the two diffracted light beams, which are directed oppositely to of the diffracted light beams, intersect each other on the first point. Thus, the diffracted light beams advance as if the diffracted light beams were the two light beams emerging from the first point.

Abstract: A distance between a mask and a wafer is set such that exposure light beams emerged from the mask are converged by the projection lens to be focused on the wafer. According to the present invention, two mask marks of diffraction gratings are formed on the mask and spaced at a predetermined distance from each other. When the alignment light beams are applied to the mask marks, two diffracted light beams of predetermined order emerge individually from the mask marks in such a manner that the respective optical axes of the two diffracted light beams, which are directed opposite to the advancing direction of the diffracted light beams, intersect each other one the first point. Thus, the diffracted light beams advance as if the diffracted light beams were the two light beams emerging from the first point. Therefore, the two diffracted light beams can be focused on the wafer or neighborhood of it. The diffracted light beams can be incident on a wafer mark which is formed on the wafer and is diffraction grating.

Abstract: In an electric motor unit, a spindle is rotatably supported by bearing sections of a dynamic-pressure type, and is floated along its axis by a magnetic thrust bearing. At the bearing sections, air current layers are formed in the gaps between journals of the spindle and bearings by elongated parallel grooves formed along the axis, and the spindle is supported by pressure distributed over the air current layers. In the thrust bearing, rotor magnets fixed to the spindle are attracted to stator magnets fixed to the housing and surrounding the rotor magnets. The spindle is floated along the axis by the attraction between the magnets.

Abstract: A shaft is fixed within a motor housing in an electric motor unit. The shaft is provided with bearing sections having herringbone-shaped grooves formed therein. The shaft is inserted into a hollow cylindrical spindle and the journal sections in the smooth inner surface of the spindle are allowed to face the bearing sections so as to constitute a dynamic pressure type radial bearing supporting the spindle in the radial direction. Stator ring magnets are fixed to the motor housing, and rotor ring magnets are fixed to the hollow cylindrical shaft. The inner surface of the stator magnets faces the outer surface of the ring magnets. These magnets are magnetized such that the mutually facing regions have opposite magnetic poles. The stator and rotor magnets form a magnetic thrust bearing; that is, the spindle is suspended by the attractive force generated between the magnets.
