A variable capacitance element includes a movable element provided above a substrate using supporting portions and support beams so as to be displaced from the substrate. An insulating film and a movable electrode are provided on a conductor facing surface of the movable element. A driving electrode is arranged to displace the movable element, between a signal cutoff position and a signal passage position, whereby a high frequency signal transmitted through a transmission line is cut off or allowed to pass. The insulating film uses compressive stress to warp the movable element and the movable electrode in a direction of warping in a convex form toward the transmission line, and maintains this warping direction.

Solid electrolytic capacitors comprise a valve metal member having a dielectric film, with or without a conductive underlying layer, formed on the member, and a conductive polymer film formed on the layer. The conductive polymer film is formed by electrolytic polymerization of a polymerizable monomer contained in a system which comprises the monomer, a support electrolyte, and at least one member selected from silicic acids and silicates with or without phenol compounds. By this, the life of the capacitor even under high temperature and high humidity conditions is significantly improved. Methods for fabricating such capacitors are also described.

An apparatus for detecting the rotation speed of a rotatory member such as a rotary shaft of an electric motor comprises a first counter for counting the pulses of a pulse signal of a frequency proportional to the rotation speed of the rotatory member, a presettable down-counter for counting down a predetermined value sequentially in response to clock pulses, and a CPU for reading out the count value of the first counter upon completion of prescribed count-down of the presettable down-counter and computing the rotation speed of the rotatory member on the basis of the count value thus read out. And upon termination of such computation, the CPU changes the count value of the presettable down-counter back to the predetermined value.

Terminals of upstream and downstream sides of an in-service line and a detour line are connected by optical couplers. An optical oscilloscope is connected to one optical coupler, and a chirped pulse light source is connected to the other optical coupler to thereby form dualized lines. The detour line includes an optical line length adjuster for compensating for the phase difference of optical transmission signals that occurs because of the optical line length difference with the in-service line. Pulse light in which an optical frequency is chirped is transmitted from the chirped pulse light source. The pulse light is branched by the second optical coupler, passes through the in-service line and the detour line, is multiplexed again by the first optical coupler, and is measured by the optical oscilloscope. While matching an arrival time of the pulse light, the optical line length is adjusted by the optical line length adjuster so as to minimize the size of upper and lower limits of an interference waveform generated in an upper part of the pulse light waveform or so as to make a frequency of an interference waveform become zero.
