摘要： A movable plate is fastened to a substrate via flexure parts and can move upward and downward with respect to the substrate. The substrate serves as a fixed electrode. The movable plate has second electrode parts which generate an electrostatic force between these electrode parts and the substrate by virtue of a voltage that is applied across these electrode parts and the substrate and a current path which is disposed in a magnetic field, and which generates a Lorentz force when powered. A mirror advances into and withdraws from the optical path. When the movable plate moves from the lower position in which the electrostatic force is increased to the upper position, the control part controls the current so that the Lorentz force is generated in a downward orientation and gradually decreases while the movable plate moves from an intermediate position to the upper position.

摘要： A movable plate 21 is fastened to a substrate 11 via flexure parts 27a and 27b, and can move upward and downward with respect to the substrate 11. The substrate 11 also serves as a fixed electrode. The movable plate 21 has second electrode parts 23a and 23b which can generate an electrostatic force between these electrode parts and the substrate 11 by means of a voltage that is applied across these electrode parts and the substrate 11, and a current path 25 which is disposed in a magnetic field, and which generates a Lorentz force when powered. A mirror 12 which advances into and withdraws from the optical path is disposed on the movable plate 21. When the movable plate 21 is caused to move from the lower position in which the electrostatic force is increased to the upper position, the control part controls the current so that the Lorentz force is generated in a downward orientation and gradually decreases while the movable plate 21 is moving from an intermediate position to the upper position. As a result, the mobility range of the movable part can be expanded without applying a high voltage or sacrificing compact size, and the power consumption can be reduced; furthermore, the reliability in the case of long-term operation can be increased.

摘要： A method of manufacturing a field effect transistor uses a semiinsulating substrate consisting of a compound semiconductor, and an N type semiconductor layer formed on the substrate. The method comprises the steps of implanting ions of a P type impurity from the main surface of said semiconductor layer to form at least two P type gate regions which extend from the main surface to substantially reach said substrate and are disposed with a predetermined interval, and sintering metallic layers on the gate regions in ohmic contact and on opposite sides of the semiconductor layers with said semiconductor gate regions being interposed therebetween to form a gate, a source and a drain electrodes. Said implantation step further comprises a step of positioning at least two of said gate regions such that said gate regions come in contact with the boundary region of the transistor to be constructed.The method of manufacturing the field effect transistor is useful for fabricating the field effect transistor at a high yield which is suitable to assemble an integrated circuit.
