摘要： PROBLEM TO BE SOLVED: To provide a stroke amount detecting device that reduces an influence on detection accuracy due to adhesion of a magnetic foreign matter such as iron powder.SOLUTION: A first magnet 21 and a second magnet 22 are magnetized such that magnetic poles facing each other have different polarities from each other, are disposed at one side with respect to a straight axis x and are obliquely disposed with respect to a reference axis y. The distance between an open end 21a and an open end 22a that are disposed at a side closer to the straight axis x is relatively long, and the distance between a gap end 21b and a gap end 22b that are disposed at a side further from the straight axis x is relatively short. A narrow air gap 4 is formed between the gap end 21b and the gap end 22b. Thus, when iron powder Fe mixed into a device adheres to the gap end 21b and the gap end 22b, the vector directions of magnetic fluxes between the open end 21a and the open end 22a do not change. Therefore, the detection accuracy of a stroke amount detecting device 1 is maintained without affecting the output of a magnetic resistance element 5.

摘要： PROBLEM TO BE SOLVED: To improve detection accuracy of a magnetic angle sensor for detecting a rotation angle over 360 degrees.
SOLUTION: A pair of partly cylindrical magnets 9 is arranged in symmetry of rotation with a magnetic detecting element 6 interposed between, and a yoke 8 surrounds the magnetic detecting element 6 in contact with outer peripheral surfaces of the pair of the cylindrical magnets 9. The pair of the cylindrical magnets 9 rotates around an axial center m with a concurrent axial displacement along with a rotation of a rotating body 1. The pair of the cylindrical magnets 9 is arranged in inclined manner with respect to the axial center m. The number of times of rotation can be determined by the size of a magnetic field detected by the detecting element 6, due to the rotation and the displacement in the axial direction with respect to the detecting element 6 of the pair of the cylindrical magnets 9. The pair of the cylindrical magnets 9 improves the size and linearity of the magnetic field on the axial center m.

摘要： PROBLEM TO BE SOLVED: To enable an eddy current type conductor detecting apparatus which detects a rotation number and a positional relation between itself and a conductor of a turbocharger or the like, to precisely detect the conductor by reducing output variations due to changes in temperature.
SOLUTION: The eddy current type conductor detecting apparatus is equipped with a signal processing circuit which detects positional information of the conductor in relation to a coil based on a signal voltage output from an LC parallel connected circuit of the eddy current type conductor detecting apparatus. In the eddy current type conductor detecting apparatus, an output difference between outputs in high-temperature and low-temperature conditions has two identity points on a frequency axis, and a considerably large output difference can be ensured at frequencies of the two identity points in the high-temperature and low-temperature conditions. Therefore, if AC current having a frequency equal to one of the frequencies of the two identity points is applied to the LC parallel connected circuit, at least an output variation occurring between a prescribed low-temperature condition and a prescribed high-temperature condition can be canceled, thereby enabling any output error due to temperature changes to be canceled, and enabling the rotation number to be detected precisely regardless of the temperature changes.

摘要： PROBLEM TO BE SOLVED: To provide a vehicle control device for automatically securing a stopped state of the vehicle when the power supply is cut off in the vehicle in which the shift range is changed by an electric means. SOLUTION: The vehicle control device is used for the vehicle in which the shift range is changed by the electric means. The vehicle control device comprises a power supply condition discriminating means 808, an energy accumulating means 801, an energy releasing means 803 for releasing the energy in the energy accumulating means 801 based on the result of discrimination by the power supply condition discriminating means 808, and a vehicle fixing means.

摘要： PROBLEM TO BE SOLVED: To highly accurately detect a rotation state of a DC motor regardless of the rotation speed while preventing torque fluctuation without providing a sensor such as an encoder. SOLUTION: A soft magnetic protrusion 13 is provided on the inner peripheral face of a housing 10 of a motor 2. An air gap between a rotor core 20 and the housing 10 (including the protrusion 13) is changed by the protrusion 13 along with the rotation of the rotor core 20. Therefore, the magnetic resistance of the motor 2 is also changed, thereby changing an inductance between brushes 18, 19 of the motor 2 along with the rotation. On the other hand, a driving DC voltage is applied to the motor 2 from a DC power supply 6, however, an AC voltage from an AC component generating part 7 is superposed on the DC voltage. Consequently, the amplitude of an AC component included in a current flowing in the motor 2 is changed along with the rotation of the motor 2. A rotation-signal detecting part 4 generates a rotation pulse on the basis of amplitude changes of the AC component included in a conduction current. COPYRIGHT: (C)2011,JPO&INPIT
