The first slider is caused to move relative to the base plate along an X axis by a first actuator. The second slider moves in unison with the first slider, and also is caused to solely move along a Y axis by a second actuator. A magnetic sensor unit is provided in the base plate, and a magnet support is provided in the second slider so as to face the magnetic sensor unit. A magnet is disposed on a lower face of the magnet support. The magnetic sensor unit and the magnet form a position detection mechanism, and the second slider in which the magnet is disposed requires no electric wiring.

摘要： On an Si substrate 1, a buffer layer 2, a SiGe layer 3, and an Si cap layer 4 are formed. A mask is formed on the substrate, and then the substrate is patterned. In this manner, a trench 7a is formed so as to reach the Si substrate 1 and have the side faces of the SiGe layer 3 exposed. Then, the surface of the trench 7a is subjected to heat treatment for one hour at 750° C. so that Ge contained in a surface portion of the SiGe layer 3 is evaporated. Thus, a Ge evaporated portion 8 having a lower Ge content than that of other part of the SiGe layer 3 is formed in part of the SiGe layer 3 exposed at part of the trench 7a. Thereafter, the walls of the trench 7a are oxidized.

摘要： In an image retrieving apparatus for retrieving a retrieving image in an input image, a color histogram of an image in a retrieving area in the input image is compared with a color histogram of the retrieving image. At first, a candidate area in which the retrieving image can be included is roughly retrieved by rough image retrieving with selecting a larger retrieving area and a rough resolution of gradation of the histograms. Subsequently, an area including an image corresponding to the retrieving image is precisely retrieved by fine image retrieving with a smaller retrieving area and a fine resolution of gradation of the histograms.
