A fixing device includes a heating element fixedly supported during a fixing procedure, a film, apparatus enabling the film to slide against the heating element, and a pressurizing roller for pressing a recording material on which a toner image is supported against the film. The heating element has a substrate, a heat generating layer provided on the substrate, and a heat-melting portion provided on the substrate. The heat-melting portion melts at a temperature higher than the fixing temperature and lower than the withstanding temperature of the substrate and thereby disconnects the heat generating layer from its power source.

High-frequency circuit components are disclosed in which parasitic capacitance between a high-frequency circuit element and a substrate is reduced and mechanical strength is improved. An exemplary component has a conductive substrate, a coil as the high-frequency circuit-element, a mounting board including a thin dielectric film on which the coil is mounted, and a support board that couples the mounting board to the substrate. The mounting board is coupled so that it floats relative to the substrate as a result of deliberate warping of the support board.

The light guide substrate 2 has mirror receiving grooves 24 and light guides. The light guides conduct light that is input into the input ports to selected output ports in accordance with the advance and retraction of the mirrors 31 with respect to the grooves 24. The actuator substrate 4 has mirrors 31 and actuators which place the mirrors 31 in a state in which the mirrors are drawn in toward the substrate 4, or a state in which the mirrors protrude from the substrate 4. The light guide substrate 2 and actuator substrate 4 are aligned using alignment marks and joined with a spacer 3 interposed so that the mirrors 31 retract from the grooves 24 when the mirrors 31 are drawn in toward the substrate 4, and so that the mirrors 31 advance into the grooves 24 when the mirrors 31 protrude from the substrate 4. This alignment is performed in a state in which all of the mirrors 31 are drawn in toward the substrate 4.

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.

An optical device is configured such that an insertion plate is held by a flat cantilever having electric wiring, and the flat magnet is placed in such a manner that the magnet faces a surface of the cantilever opposite to the other surface of the cantilever facing an optical waveguide, and that the current flowing through the electric wiring is controlled in this state so that the Lorentz force caused by the interaction between the current and the magnetic field displaces the cantilever to drive the insertion plate, and to insert or remove the insertion plate into or out of the slit provided in the optical waveguide to switch the optical path of signal light or to adjust the quantity of an optical beam.
