    摘要： In one embodiment, an actuator has a movable member, a frame, and first and second electrodes. Each of the first electrodes has a pair of first and second planes perpendicular to a third direction which is orthogonal to the first and the second directions approximately. The second electrodes are provided alternately with the first electrode respectively and with a distance from the first electrode. Each of the second electrodes has a pair of third and fourth planes perpendicular to the third direction. The first and the second planes have a deviation in the third direction with respect to the third and the fourth planes, respectively. The amount of the deviation is larger than a maximum value of the amount of displacement of the movable member in the third direction. The amount of displacement is produced by gravity when a component of the gravity in the third direction is maximum.

    摘要： According to one embodiment, an actuator includes a substrate, a lower electrode disposed on the substrate, an upper electrode, a support and a driving unit. The upper electrode is opposed to the lower electrode. The support supports the upper electrode. The driving unit is connected between the lower electrode and the upper electrode and feeds a driving voltage. The driving voltage at which the lower and upper electrodes start to come into contact with each other is defined as a pull-in voltage. A capacitance between the lower and upper electrodes is defined as a pull-in capacitance. There exist a first region and a second region. In the second region, a change rate of a capacitance ratio changes more slowly than in the first region, when the absolute value of the potential difference is further increased. The driving unit feeds the driving voltage in the second region.

    摘要： A storage device includes a storage medium and a plurality of probes. The probes each have a recording/reproducing portion. The probes include a first probe, a second probe spaced from the first probe in a first direction, and a third probe spaced from the first probe in the first direction and in a second direction different from the first direction. A distance Xp1 in the first direction between the portions of the first and second probes, a distance Xp2 in the first direction between the portions of the first and third probes, and a distance Yp2 in the second direction between the portions of the first and third probes satisfy the following formulae: Xp1=n×Xm Xp1=Xm Yp2=Ym/n  [Math 1] (, provided that n=2, 3, 4, - - - ), where Xm and Ym are lengths of each area in the first and second directions, respectively.
