    Abstract: A torque detection apparatus for measuring a torque applied between a drive shaft and an output shaft which is applicable to an electric power steering system of a motor vehicle. The torque detection apparatus is provided between the drive and output shafts and comprises first and second rotating bodies which are respectively at one end portions coupled fixedly to the drive and output shafts, the first rotating body being rotatable in accordance with rotation of the drive shaft and the second rotating body being rotatable in accordance with rotation of said output shaft. The first and second rotating bodies are shaped cylindrically and the first rotating body has on its outer circumferential surface magnetic toothed portions and the second rotating body has on its inner circumferential surface magnetic toothed portions. The first and second rotating bodies are disposed coaxially so that the magnetic toothed portions are magnetically engaged with each other so as to form a first magnetic flux path and a second magnetic flux path. The torque between the drive and output shafts is measured on the basis of the difference between the amounts of the magnetic fluxes passing through the first and second magnetic flux paths.

    Abstract: A method of fabricating a reactor composed of a coil, a core, and a container, capable of suppressing the core to break when a current flows in the coil to generate magnetic flux. In the method, the coil is formed by spirally winding a conductive wire. The coil is immersed in an insulating film in liquid with electrical insulation. The coil is placed in a furnace. Annealing for the coil and thermosetting for the insulating film are performed at a temperature within 250 to 320° C. for a period of time within 30 minutes to one hour before forming the core in the container. The coil is then disposed in the container. Inside and outside areas of the coil in the container is filled with a resin mixture composed of magnetic powder and resin. The resin mixture in the container is hardened to form the core.

    Abstract: A throttle valve control apparatus comprises a throttle valve element supported on a valve shaft, a wire for transferring a force of an accelerator operation part to the throttle valve element, a motor for driving the throttle valve, and a stopper member for transferring a driving force of the motor to the valve shaft. The stopper member has a gear part driven by the motor and a restraint part for restraining an opening degree of the throttle valve. A notch is provided near the restraint part. The driving force of the motor is transferred from the gear part to the stopper member at the time of traction control. The restraint part of the stopper member thus drives the throttle valve element in the close direction. The notch prevents the stopper member from coming in contact with the valve shaft.

    Abstract: A control apparatus detects a suitable starting point during rotational oscillation of a rotor at the start of a brushless motor by combining the polarity of a counter electromotive force generated in an armature coil of an armature winding of the brushless motor for a nonexcited phase due to the rotational oscillation of the rotor (when armature coils for particular phases are excited at the start of the brushless motor) with the pulse edge of an excitation switchover signal obtained from the potential of a neutral point of the armature winding having the armature coils connected in star-connection and that of a neutral point of a detecting resistance circuit having resistors connected in star-connection. Each of the resistors of the resistance circuit is arranged in parallel with a corresponding one of the armature coils the armature winding. By driving the brushless motor from the detected suitable starting point, it is possible to effect smooth and quick control of the starting operation of the brushless motor.
