摘要： A stator is provided with a ring-shaped outer stator-projection and a ring-shaped inner stator-projection. A plunger is provided with a ring-shaped outer plunger -projection and a ring-shaped inner plunger-projection. A magnetic force is generated at three portions between the plunger and the stator. The inner stator-projection has a first tapered surface and the outer plunger-projection has a second tapered surface. The first tapered surface and the second tapered surface confront each other when the plunger moves toward the stator.

摘要： A rotation angle detector is provided with a frame-shaped yoke which includes a first wall and a second wall in parallel. A rotation axis of a detection subject extends inside of the frame-shaped yoke. A magnetic flux vector is uniformed in a direction orthogonal to the first wall, whereby even if a position of a Hall element deviates, the detected magnetic flux density is less varied. A robustness of the detector is enhanced. A distance between the Hall element and a second inner surface of the second wall is shorter than that between the Hall element and a first inner surface of the first wall. A length of the second inner surface is longer than a length of the first inner surface. At a vicinity of the second wall, the area in which the magnetic flux vector is uniformed can be enlarged. Thus, the robustness is further enhanced.

摘要： A stroke amount detecting device includes a first magnetic field generation member, a second magnetic field generation member, and a magnetic sensor unit. The first magnetic field generation member and the second magnetic field generation member are opposed to each other with respect to a direction perpendicular to a straight stroking axis of a stroking object, and magnetized in opposite directions. The magnetic sensor unit is movable in an area between the first magnetic field generation member and the second magnetic field generation member, along a straight traveling axis that is parallel to the straight stroking axis relative to the first magnetic field generation member and the second magnetic field generation member in accordance with a stroke motion of the stroking object. The magnetic sensor unit has a magnetosensitive surface facing a direction parallel to the traveling axis, thereby to detect an amount of stroke of the object.

摘要： A magnetic sensing surface of a stroke sensor is placed in an angular range between a first imaginary line and a second imaginary line. The first imaginary line is an imaginary line that coincides with a center line between first and second magnets of a magnetic movable body when a wastegate valve is placed to have a full close degree of the wastegate valve. The second imaginary line is an imaginary line that coincides with the center line between the first and second magnets when the wastegate valve is placed to have a half degree between the full close degree and a full open degree of the wastegate valve.

摘要： A rotational angle detecting device includes a magnetic member, a magnetic sensor and a processing unit. The magnetic sensor includes a sensor element disposed to rotate relative to the magnetic member in accordance with a rotation of a rotating object and outputting signals according to a change in a magnetic field caused as rotating relative to the magnetic member. The processing unit is capable of processing output values of the sensor element. The processing unit acquires the output value at every angle of rotation of the rotating object, estimates a waveform for one cycle of the signals as an estimation waveform from the acquired output values, and normalizes an amplitude of the estimation waveform. Further, the processing unit calculates a rotational angle of the rotating object by a trigonometric function operation based on the output value and the normalized amplitude.
