摘要： A rotation angle sensing device for detecting a relative rotation angle between a rotor and a stator includes main magnets, fixed in the rotor, and hole ICs, fixed in the stator. The hole ICs detect magnetic flux of the main magnets , and the relative rotation angle therebetween is detected. A supportive magnet is disposed between the hole ICs so as to offset the magnetic flux of the main magnets. Accordingly, a rotation angle in which the magnetic flux density detected in the hole ICs becomes 0 [mT] can be changed by the supportive magnet. Therefore, a 0° position of the rotation angle can be set to the rotation angle in which the magnetic flux density is detected as 0 [mT], and moreover the detectable range of the rotation angle can be enlarged to be more than 90°.

摘要： An exhaust emission control device reduces nitrogen oxide in exhaust air from an engine. The device includes an exhaust pipe, a catalyst, a supply device, a NOx detecting device, and a control device. The pipe defines a passage for the exhaust air. The catalyst is disposed in the pipe and promotes reduction reaction of the nitrogen oxide. The supply device supplies an additive agent, which is used for the reaction, to an upstream side of the catalyst in the exhaust air flow direction. The detecting device detects the nitrogen oxide included in the exhaust airs which has passed through the catalyst. The control device controls the supply device. The control device determines a deterioration state of the catalyst based on a result detected by the detecting device and reduces an amount of the additive agent, which is supplied, according to the determined deterioration state.

The rotation angle detecting device includes a magnet unit fixed to the first member and a pair of magnetic sensors fixed to the second member to provide output signals whose phase is different from each other at 90 degrees in angle. The magnet unit includes a pair of disk plates that has the same magnetic poles at the same circumferential positions and is disposed at a prescribed axial distance and a shaft that is made of magnetic material to support the disk plates at the center thereof.
