摘要： A first sensor element outputs a first output signal in correspondence to a direction of the magnetic flux lines acting from the outside. A second sensor element outputs a second output signal associated with the first output signal in correspondence to a direction of the magnetic flux lines acting from the outside. A first conversion processing section converts the first output signal output from the first sensor element and the second output signal output from the second sensor element into the second physical quantity. A second conversion processing section converts the first output signal output from the first sensor element and the second output signal output from the second sensor element into a signal representing the rotation angle of the motor.

摘要： A thermal gas-flow measuring instrument has a first heating resistor placed in the gas to be measured. A temperature sensing resistor is positioned upstream or downstream of the first heating resistor and generates signals relating to the flow rate. Between the first heating resistor and the support for supporting the first heating resistor is a second heating resistor that is electrically insulated from the first heating resistor. The second heating resistor suppresses the heat being transferred from the first heating resistor to the support. A control circuit controls the temperatures of the first heating resistor and the second heating resistor so that the operational temperature range of the second heating resistor or the temperature range at the joint section between the first heating resistor and the second heating resistor is at or above the temperature at which water droplets evaporate to disappear by film boiling.

摘要： An exhaust recirculation control system of the internal combustion engine computes an oxygen concentration in total intake air containing recirculation exhaust gas in a cylinder and the ratio between an oxygen quantity in the total intake air and a fuel injection quantity (oxygen quantity/fuel injection quantity ratio). The computed values are compared with target values which are pre-set according to engine operating conditions and, based on the result of the comparison, at least an EGR valve or a fuel injection quantity. In order to perform such a control with high accuracy, a correcting means corrects a recirculation exhaust gas mass flow signal from a gas mass flowmeter on the basis of a predicted exhaust gas component concentration. And, by using the corrected recirculation exhaust gas mass flow, oxygen concentration in total intake air containing the recirculation exhaust gas in the cylinder and the ratio between the oxygen quantity in the total intake air and the fuel injection quantity (target oxygen quantity/fuel injection quantity ratio) are computed to perform EGR control.
