When a voltage is applied to plural spot electrodes selected from the spot electrodes arranged in the matrix form and the light incident on the two-dimensional plane waveguide is reflected by at least two parallel lines, the refractive index of the optical waveguide is partly changed so that the wavelength of the light, the angle of the two lines to the incident light and the distance between the lines satisfy the Bragg reflection condition.

A buckling actuator has a connecting section of a supporting beam that is provided with a rotatable supporter for allowing a movable member to be stably maintained at one of two switch positions. A substrate, stationary members, rotatable supporters, and supporting beams support a movable member in a shiftable manner in a y-axis direction, such that the movable member can be shifted between first and second switch positions. Moreover, the rotatable supporters are each provided with arm portions which extend in a radial fashion and support the corresponding supporting beam in a rotatable manner. When the movable member is being shifted, each supporting beam scan be rotated without having to bend a corresponding end by a significant amount. Thus, a large barrier ΔE of potential energy of the movable member is set between the first and second switch positions. The movable member can therefore be stably maintained at each of the switch positions even when electric power is not supplied to electrodes. Furthermore, each arm portion prevents the movable member from being displaced in an x-axis direction.

A variable resistance element is configured to be provided with a perovskite-type oxide between a first electrode and a second electrode, of which electric resistance between the first electrode and the second electrode is changed by applying a voltage pulse of a predetermined polarity between the first electrode and the second electrode, and the variable resistance element has a resistance hysteresis characteristic, in which a changing rate of a resistance value is changed from positive to negative with respect to increase of a cumulative pulse applying time in the application of the voltage pulse. The voltage pulse is applied to the variable resistance element so that the cumulative pulse applying time is not longer than a specific cumulative pulse applying time, in which the changing rate of the, resistance value is changed from positive to negative with respect to increase of the cumulative pulse applying time in the resistance hysteresis characteristic.

The present invention is a coating unit for applying a coating solution to a substrate which includes: a discharge nozzle for reciprocating in a predetermined direction above the substrate and discharging the coating solution to the substrate; a holder for holding the substrate and horizontally movable in one direction perpendicular to the predetermined direction; and a cover for covering an upper face of the substrate when the substrate is moved in the one direction to be more forward than the discharge nozzle as viewed from a plane, wherein a lower face of the cover is inclined such as to be higher on the discharge nozzle side. According to the present invention, the cover covering the upper face of the substrate restrains a solvent from evaporating from the coating solution applied on the substrate to secure flatness of a coating film.
