摘要： PROBLEM TO BE SOLVED: To provide an engine starter capable of starting up an engine without causing voltage decline of 2V or more during engine startup time.
SOLUTION: An engine starter 1 is equipped with a motor 2, having a series coil 2b and a shunt coil 2c; a startup resistance 4 connected in series with an armature 2a of the motor 2; and a control element 6, designed to control field current of the shunt coil 2c, and energizes to the motor 2 through the startup resistance 4 during engine startup time. As a result, startup (rush) current to the motor 2 is reduced so that voltage decline of a battery 8 is restrained to be 2V or less. Also because a high torque-type motor is used for the motor 2, it is possible to secure the torque necessary for exceeding the first top dead center even if the startup current for the motor 2 is little. After surpassing the first top dead center, furthermore, it is possible to secure the number of cranking rotations required for engine startup by obtaining the high rotation characteristic through control of the field current for the shunt coil 2c.

摘要： PROBLEM TO BE SOLVED: To solve a problem of being incapable of detecting 90° or more by setting a magnetic flux density around a throttle valve of 0° where the detection precision is required most to the magnetic flux density of 0, in a magnet having characteristics that a magnetic flux density is changed according to a temperature, the change in temperature characteristics is minimized when the magnetic flux is 0, and a magnetism detection precision around the magnetic flux density of 0 is high.
SOLUTION: A supportive magnet 8 offsetting the magnetic flux density provided from main magnets 4 to Hall ICs 6 by applying a prescribed magnetic flux density to the Hall ICs 6 is fixedly disposed between the two Hall ICs 6. This constitution can change the angle in which the magnetic flux density becomes 0 by the supportive magnet 8. Therefore, while an angle 0° position where the detection precision is required most is set to the magnetic flux density of 0, the detectable range of the rotation angle can be extended to be more than 90°.

摘要： PROBLEM TO BE SOLVED: To provide a displacement sensor with high detection accuracy.
SOLUTION: An opposing section 22 opposite to a shaft 70 which moves linearly together with a moving body to be detected is composed of an circular arc section 31 of a first yoke 30 and an circular arc section 41 of a second yoke 40. A Hall IC 60 is arranged so that magnetic flux flowing from a magnetic channel section 32 to a magnetic channel section 42 through the Hall IC 60 vertically penetrates the detection surface of the Hall IC 60. A variable resistance means composed of the opposing section 22 and the shaft 70 is arranged parallel to the Hall IC 60. As the shaft 70 moves together with the moving body in the direction of arrow Y, the gap between the opposing section 22 and the shaft 70 becomes small, and the magnetic resistance between the opposing section 22 and the shaft 70 becomes small. The magnetic flux easily flows between the opposing section 22 and the shaft 70, and therefore the magnetic flux flowing the Hall IC 60 is reduced, and the magnetic flux density detected by the Hall IC 60 becomes little.

摘要： PROBLEM TO BE SOLVED: To reduce cost and size of the whole of a device by suppressing busy count of means of superposing an AC voltage onto a DC voltage to each DC motor for the purpose of rotation state detection, in a rotation detection device having a configuration for detecting rotation states of a plurality of DC motors on the basis of change in AC components energized respectively.SOLUTION: An AC voltage is superposed from an AC superposition part 4 onto a common connection node N0 in an energization path between the other brush 17 of a first motor M1 and one brush of a second motor M2, and thereby, an AC current flows in the respective motors M1 and M2. Since the respective motors M1 and M2 have a configuration in which an impedance between a pair of brushes is periodically changed with rotation, the AC current flowing in the motors M1 and M2 is changed periodically with rotation. Therefore, respective AC detectors 6 and 7 detect the AC current flowing in the respective motors M1 and M2, and rotation pulses SP1 and SP2 are generated on the basis of the change in the AC current.

摘要： PROBLEM TO BE SOLVED: To detect a rotating state of a direct-current motor with a brush with high accuracy independently of a rotational speed while controlling a torque fluctuation without providing a sensor of an encoder or the like. SOLUTION: A power supply unit 5 applies an alternating-current voltage superposed upon a direct-current voltage to a motor 2. A current including an alternating-current component flows when the motor 2 rotates. In the motor 2, a first phase coil L1 among phase coils L1, L2 and L3 for 3 phases is connected in parallel to a capacitor C1, impedance of a motor circuit between each of brushes 16 and 17 changes by the capacitor C1 according to rotation of the motor 2, and the change appears as an amplitude change of the alternating-current component of a motor current. A signal processor 22 extracts the alternating-current component from the motor current detected by a current detector 21, and generates a rotation pulse corresponding to the amplitude change. A rotation angle detector 7 detects a rotation angle of the motor 2 based on the rotation pulse. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a rotation angle detector capable of preventing a rotation detection error from being generated, even if relative positional shifts are generated between a magnet and the first and second magnetic sensors.
SOLUTION: The two disk-shaped magnets 2, having the same direction of magnetic flux and the same performance, are fixed onto a shaft 1 made of a magnetic substance with a prescribed space. A closed magnetic field with magnetic flux lines aligned radially is formed, in a space in a z-axis direction central part of the two magnets 2 and in the center of an outer circumferential end of the shaft 1 and an outer circumferential end in the magnets 2. The first and second magnetic sensors 3, 4 are arranged in the space formed with the closed magnetic field. The first and second magnetic sensors 3, 4 are arranged in the vicinity of a circumference of the one magnet 2 in conventional rotation angle detectors, the rotation detection errors thereby become large, because of the positional shift between the first and second magnetic sensors 3, 4; but the rotation detection errors are prevented from being generated in the constitution of the present invention, since changes in the directions of the magnetic flux lines imparted to the first and second magnetic sensors 3, 4 are restrained, even if the attachment positions for the first and second magnetic sensors 3, 4 are slightly shifted.

摘要： PROBLEM TO BE SOLVED: To provide an inexpensive small-sized rotation angle detection device capable of measuring the rotation angle in the range of 360 degrees.
SOLUTION: A permanent magnet 2 is mounted on a rotating shaft 3, and generates a main magnetic field MF. A coil 5 generates an auxiliary magnetic field SF. The main magnetic field MF is rotated relative to the auxiliary magnetic field SF following rotation of the rotating shaft 3. Two magnetic resistance sensors are arranged in a sensor unit 4 so as to output electric signals having the phase difference of 45 degrees mutually. The main magnetic field operates both magnetic resistance sensors of the sensor unit 4 in a saturated region regardless of the rotation angle of the rotating shaft 3. Each magnetic resistance sensor outputs an electric signal of a level corresponding to the direction of the magnetic field regardless of the intensity of the magnetic field in the saturated region. A composite magnetic field formed by the main magnetic field and the auxiliary magnetic field forms the saturated region at the angle at which one magnetic resistance sensor outputs the maximum level, and forms an unsaturated region at the opposite angle by 180 degrees. The level of an electric signal outputted from each magnetic resistance sensor in the unsaturated region is lower than the level outputted in the saturated region.
