    摘要： An on-vehicle fiber-optic cylinder pressure sensor capable of detecting the pressure within a combustion chamber with precision has an optical fiber capable of converting a change in the pressure within a combustion chamber received on its outer surface on an engine gasket into a change in the light quantity passing therethrough. A light emitting device for emitting the passed-through light; a photosenses or senses the passed-through light of which the light quantity has been changed. A converter converts the light quantity of the passed-through light into an electric signal. A reference pressure setting apparatus sets a reference electric signal. A signal processor includes an apparatus for watching a corresponding reference electric signal to the reference electric signal included in the detected electric signal.

    摘要： An optical fiber pressure sensor for measuring a pressure on the basis of an optical power loss depending on a configuration change of an optical fiber comprising a luminescence device optically connected with at least an optical fiber which is constructed with a main part for propagating a light protective coating member for protecting the main part. A light intercepting device detects a light passing through the optical reflected light from the optical fiber. A bending device bends at least a part of the optical fiber according to a measured pressure. The optical fiber pressure sensor is characterized by being used when a normalization frequency V value of the optical fiber is smaller than 90% of a normalization cut-off frequency defining a single transmission mode condition of the optical fiber.

    摘要： A battery voltage Ef of a fuel cell 1 is detected, and a current instruction value which transformed an electric power instruction value Pfc of the fuel cell is reduced at falling-down of the voltage Ef. A current limiter 8 makes the current instruction value a limit value at the time of the falling-down of Ef, and reduces the limit value according to the fall of Ef. For example, current instruction value is restricted so as to begin to reduce battery current IFC at voltage drop alarm level (first threshold value), and become zero at voltage drop protection level (second threshold value).
