摘要： The present invention relates to a slim-type small size mirror galvanometer wherein the mirror displacement angle can be detected, made using semiconductor manufacturing techniques. Using semiconductor manufacturing techniques, a movable plate 5 and a torsion bar 6 for axially supporting the movable plate 5 are formed integrally on a silicon substrate 2, with a planar coil 7 and a total reflecting mirror 8 formed on an upper face of the movable plate 5, and permanent magnets 10A, 10B and 11A, 11B fixedly located so as to produce a magnetic field at the planar coil 7. The direction and quantity of current flowing in the planar coil 7 is controlled to variably control the swing angle of the movable plate 5 depending on the balance between the generated magnetic force and the torsion force in the torsion bar 6. Moreover, detection coils 12A, 12B are provided beneath the movable plate 5, and a detection current is superimposed on the drive current in the planar coil 7. The mirror displacement angle is detected by a change in the mutual inductance due to the detection current, between the planar coil and the detection coils 12A, 12B.

摘要： A fail-safe logic circuit employs a transformer (T) and a level tester (1). The transformer receives input signals each representing a binary logic variable and provides the sum of magnetic flux based on the input signals. The level tester tests the level of the sum of the magnetic flux and provides a binary output (y) representing a logic value of 1 or 0. This circuit is simple and capable of lowering an output level.

摘要： A scanning mirror unit for scanning a beam comprises: at least one cantilever which is formed by bonding an elastic material and a piezoelectric material together and supported by a base at its one end; and a movable mirror which is supported at least by a free end of the cantilever at its peripheral part. When voltage is applied to the piezoelectric material, the free end of the cantilever moves in a prescribed direction to press and move the peripheral part of the movable mirror while leaving a central part of the movable mirror at substantially the same position to cause a tilt to the movable mirror. With such composition of the scanning mirror unit, a reflecting member having a sufficient thickness (e.g. some hundreds of microns) can be employed for the movable mirror, by which a high power laser beam effective for treatment of affected parts, etc. can be reflected finely and durably.

In the extending and retracting mechanism, the SMA made actuator is fastened to the liner coil spring upon deformation to have a length varied from a length of the SMA made actuator in its natural state. In the torsionally rotating mechanism, the SMA made actuator is fastened to the liner coil spring upon deformation to have a coil diameter torsionally varied from a coil diameter of the SMA made actuator in its natural shape memory step. The stiffness control mechanism has an SMA made actuator in its natural shape memory state.
