The first and fifth GMR devices, and the second and sixth GMR devices are disposed in a symmetrical manner as to the point of origin, and accordingly the intensity and direction of an external magnetic field applied from a rotating magnet is the equal between the first and fifth GMR devices, and also equal between the second and sixth GMR devices.

摘要： A magnetic switch hardly affected by an external magnetic field even if a cheap magnet is used and capable of performing magnetic detection for a long period of time is provided. A first magnetic path L1 and a second magnetic path L2 in which a stationary rail 13 and a movable rail 14 lead magnetic fluxes are formed in a non-shielding state where magnetism shielding 18 is not interposed in a gap G between a magnet M and a Hall element H to secure the number of magnetic fluxes that pass through the Hall element H. Therefore, it is not necessary to use a costly rare earth magnet having a large number of generated magnetic fluxes. In n shielding state where the magnetism shielding 18 is interposed in the gap G, the first magnetic path L1 is shielded. As a result, the number of magnetic fluxes that pass through the Hall element H is almost zero. Since the magnet M and the Hall element H are covered with the stationary rail 13 and the movable rail 14, the magnetic switch is hardly affected by the external magnetic field.

摘要： The absolute angle of the rotation angle is detected on the basis of a first detection signal including sawtooth continuous pulses and a second detection signal that rises stepwise. The second detection signal includes a plurality of flat portions and a plurality of gradually rising portions that link the flat portions, corresponding to the pulses of the first detection signal. Each gradually rising portion corresponds to the sharply falling portion of the first detection signal. When the value of the second detection signal is included in a flat portion, the absolute angle is found based on the first and second detection signals, and, when the value of the second detection signal is included in a gradually rising portion, the absolute angle is found based on the first detection signal in conjunction with the second detection signal corresponding to a flat portion preceding or following the gradually rising region.

摘要： A rotation angle sensor wherein when code plates rotate as a result of rotation of rotary members, detecting elements detect information on information recording portions of the code plates in order to detect the rotation angles of the rotary members. Therefore, the rotation angles of the rotary members can be detected with high precision. In conventional rotation angle sensors, a rotary drum, being a magnetic medium, is mounted directly to a rotary shaft. Therefore, when two such conventional rotation angle sensors are mounted to a rotary shaft, and a rotational torque is applied to a drive shaft portion in order to rotate a load shaft portion, so that a large load is applied to the load shaft portion, the drive shaft portion and the load shaft portion may become decentered. This causes the gap between one of the two rotary drums and its associated detecting sensor as well as the gap between the other of the two rotary drums and its associated detecting sensor to vary, making it impossible to precisely detect the difference between the rotation angles of the two rotary drums. The rotation angle sensor of the invention overcomes this problem.

摘要： A rotary position sensor includes a cylindrical housing having a partition wall which divides the interior of the housing into a first storing space and a second storing space. The first storing space stores a rotating mechanism and is closed with a first cover in such a manner that a shaft portion of a rotating member projects outside, and the second storing space stores an electrical circuit component and is closed with a second cover. A magnet included in the rotating mechanism is disposed at a position close to the partition wall, and a giant magnetoresistive element included in the electrical circuit component is disposed in a recess formed in the partition wall. Thus, the rotating mechanism and the electrical circuit component are completely separated from each other by the partition wall, so that a complex sealing process is not necessary and the detection accuracy can be increased.
