摘要： An air-fuel ratio control apparatus is disclosed in which an air-fuel ratio sensor disposed in the exhaust system of an internal combustion engine produces a voltage signal correlated with the excess air ratio of the ambient gas surrounding it and has such an output characteristic as to produce a maximum output only when the ambient gas is filled with air, the air-fuel ratio of the internal combustion engine being controlled to a proper value on the basis of the detection signal of the air-fuel ratio sensor. The air-fuel ratio control apparatus further comprises a sampling device for sampling the maximum output (V.sub.x) when it is decided that the output of the air-fuel ratio sensor is maintained for a predetermined length of time or longer at a predetermined value or higher, a memory for storing the sample value of the maximum output (V.sub.x) produced by the sampling device and updating the preceding sample value (V.sub.x-1) to the present sample value (V.sub.x) when a new maximum output is sampled each time of the decision, and a calibrator for calibrating the output characteristic of the air-fuel ratio sensor on the basis of the latest updated sample value (V.sub.x).

摘要： A variable inductor wherein two closed magnetic circuits each having a predetermined gap in one place are constructed of a movable magnetic core and a fixed magnetic core. When the movable magnetic core is moved, the opposite area between both the magnetic cores in one of the closed magnetic circuits increases, while the opposite area between both the magnetic cores in the other closed magnetic circuit decreases. Thus, the inductances of coils wound around parts of the respective closed magnetic circuits vary complementarily.

摘要： A torque detection mechanism can be provided for a power train and its control unit without newly adding a sensor and its signal processing module. As a gear pair for the torque detection mechanism of a phase difference type, existing gears in a transmission are used, or a gear pair for this mechanism are provided adjacent to these existing gears. From phase signals sent from pickups, a phase difference signal is obtained by use of one part of existing devices in the control unit. The torque detection mechanism can be realized with the minimum number of component parts by utilizing the existing members and spaces instead of newly adding a sensor and its module. The invention can be applied to either of FF and FR cars, and has a practical structure in respect of the performance, costs and reliability.
