摘要： An object of the invention is to provide a control apparatus and a control method having a simple constitution, which can stably perform switching of optical path in an optical signal exchanger, while suppressing an influence on a control due to the mechanical resonance of tilt mirrors. To this end, the control apparatus of the optical signal exchanger is constituted such that in an optical signal exchanger of three-dimensional type using one set of MEMS mirror arrays, each having a plurality of tilt mirrors arranged on a plane, each tilt mirror having a reflecting surface an angle of which is controllable, when the angle of the MEMS mirror on the optical path is feedback controlled by detecting power of an optical signal output from a specific position, a resonance component removing section that removes a resonance frequency component included in a control signal is shared corresponding to a pair of driving electrodes arranged in a coaxial direction of the MEMS mirror. As a result, the influence on the feedback control by a resonance action of the MEMS mirror can be reduced, while suppressing an increase in circuit size.

摘要： A stabilization apparatus according to the present invention comprises a stopper which is in contact under pressure with one side face of a movable body capable of swinging around a torsion bar, this one side face being vertical to an axial direction of the movable body, to damp the movable body. The stopper is displaced between a first position at which the stopper is in contact under pressure with the side face of the movable body, and a second position apart from the side face, according to a drive voltage applied to a stopper electrode. The drive voltage for the stopper electrode is controlled by a control section at the appropriate timing according to a drive condition of the movable body. As a result, the resonance operation can be reliably suppressed even when an angle of the movable mirror is changed at a high speed, and thus, it becomes possible to stabilize the movable mirror to be in a desired state in a short time.

摘要： An electrode includes a fixed electrode and a movable electrode. The electrode drives a mirror disposed on the side of the movable electrode by generating electrostatic force between the fixed electrode and the movable electrode when voltage is applied. The fixed electrode and the movable electrode are formed so that a distance between the fixed electrode and the movable electrode increases as an overlapping area between the fixed electrode and the movable electrode increases.

摘要： Instant noodles are produced, which have an excellent reconstitution property, can be reconstituted by pouring of boiling water even if the noodles are thicker than before, and have excellent taste and texture. The instant noodles are produced by: making raw noodle strings each having a multilayer structure including three or more layers; spraying superheated steam to the raw noodle strings; gelatinizing the noodle strings to which the superheated steam has been sprayed; and drying the noodle strings which have been gelatinized. It is preferable to gelatinize the noodle strings by spraying the superheated steam to the noodle strings, supplying moisture in liquid form to the noodle strings, and further heating the noodle strings by using the superheated steam and/or saturated steam.
