    摘要: An object of the present invention is to provide an optical fiber strain measuring apparatus which can perform precise measurement without causing any fluctuation in signal level. To achieve the above object the present invention comprises: a polarization plane rotation device 105 which rotates a plane of polarization of an optical pulse; a photo-directional coupler 106 which projects an optical pulse projected from the polarization plane rotation device 105 into an optical fiber 107 to be measured, and projects out backscattering light produced in the optical fiber 107 to be measured; a polarization plane rotation device 160 which rotates a plane of polarization of a reference light; a light mixing device 109 for mixing the backscattering light projected out from the photo-directional coupler 106 and the reference light projected from the polarization plane rotation device 160; and a signal processing section 111 which detects the mixed light projected from the light mixing device 109, converts the detected light into an electrical signal and subjects the electrical signal to a predetermined operational processing to obtain a measurement waveform.

    摘要: Disclosed is an apparatus for detecting abnormality in a secondary air supplier of an engine. The operational status of the engine is monitored by various sensors. When the engine is in a warmed-up state, an electronic control unit (ECU) disables the secondary air supplier to stop secondary air from being supplied to an exhaust manifold. When the engine is in such an operational status in which the secondary air should be supplied, the secondary air supplier is activated and a fuel supplying means is controlled in such a way that a suction air-fuel ratio is forcibly adjusted to a predetermined high value so as to set an exhaust air-fuel ratio low when the secondary air supplier functions properly and set the exhaust air-fuel ratio high when the secondary air supplier is abnormal. When the exhaust air-fuel ratio is detected to be high, the ECU judges the secondary air supplier as abnormal and executes necessary processing, such as outputting an abnormality judgment signal to an external warning device.
