    摘要: To realize a thermal gas-flow measuring instrument which can suppress the influence of pollution of a support of heating resistor on the output characteristics independent of the use environment. The first heating resistor (21) is placed in the gas to be measured. The temperature sensing resistor (24) which is positioned at upstream side or downstream side of the first heating resistor (21) generates signals relating to the flow rate. Between the first heating resistor (21) and the support (6) for supporting the first heating resistor (21), the second heating resistor (22) is positioned in a state of electrically insulated from the first heating resistor (21). The second heating resistor (22) suppresses the heat being transferred from the first heating resistor (21) to the support (2). The control circuit (31) controls the temperatures of the first heating resistor (21) and the second heating resistor (22) so as the operational temperature range of the second heating resistor (22) or the temperature range at the joint section between the first heating resistor (21) and the second heating resistor (22) to become at or above the temperature at which the water droplet evaporates to disappear by the film boiling.

    摘要: A first sensor element 100-1 outputs a first output signal in correspondence to a direction of the magnetic flux lines acting from the outside. A second sensor element 100-2 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 200-1 converts the first output signal output from the first sensor element 100-1 and the second output signal output from the second sensor element 100-2 into the second physical quantity. A second conversion processing section converts the first output signal output from the first sensor element 100-1 and the second output signal output from the second sensor element 100-2 into a signal representing the rotation angle of the motor.
