摘要： An optical fiber for a sensor that can measure a current or a voltage precisely is provided. The optical fiber for the sensor 10 comprises: an FBG 12 wherein a refractive index of a core changes periodically; a metal layer 13 for sheathing the FBG 12; and a pair of electrodes 14 and 15 provided at the metal layer 13. The electrodes 14 and 15 are connected to an object to be measured in desired positions. Current flowing through the metal layer 13 is calculated based on variation in Bragg wavelength of the FBG 12.

摘要： A flow rate adjustment method for a variable geometry turbocharger may include steps as follows. An adjustment apparatus drives an actuator to an abutment position where a power transmission member abuts a stopper. The apparatus acquires the abutment position opening amount based on an opening detection sensor's signal. The apparatus drives the actuator until the detection amount attains a pre-set amount, moving the power transmission member to a temporary control position. The apparatus acquires a temporary control position flow rate. It is acquired when an adjustment gas inflow apparatus causes the adjustment gas to flow into an exhaust turbine, and a flow rate measurement sensor measures the flow rate of the adjustment gas. The apparatus obtains a correction amount based on a difference between the temporary control position flow rate and a real control position flow rate, which is a proper flow rate corresponding to the pre-set amount.
