摘要： In a vehicle cornering lamp system, a control signal having a pulse width corresponding to a steering angle is periodically produced, and the amount of position shift between the actual direction of illumination of the headlamps and the target direction of illumination determined from the steering angle is detected according to the control signal thus produced. An electric motor is driven to change the direction of illumination of the headlamps so that the amount of position shift becomes zero, that is, the direction of illumination of the headlamps is linearly changed with the electric motor while following the steering angle.

摘要： A vehicle cornering headlamp system in which the direction of illumination of the headlamps of an automobile are made to follow the actual direction of movement of the vehicle, except that the direction of illumination is returned to the straight-ahead direction more quickly than it is moved away therefrom, thereby more accurately following the usual eye movement of the driver. For this purpose, a control signal is generated which has a pulse width indicative of the steering angle but which has a variation characteristic with respect to steering angle which is larger when the steering wheel is turned back towards the straight-ahead position than when the steering wheel is turned away from the straight-ahead position.

摘要： A cornering lamp system for a vehicle which changes direction of the headlamps in conjunction with the operation of the vehicle's steering mechanism. The headlamps are moved in discrete steps by use of a stepper motor.The headlamps move in the direction which the vehicle is turning, and the headlamp closest to the center of rotation moves prior to the headlamp further from the center of rotation. A delay circuit causes the headlamps to move a predetermined period of time after the direction of the steering wheel is changed.

摘要： In an actuator of a vehicle headlamp unit for deflecting a direction or a range of illumination, a step-like rib for supporting a printed circuit board is formed at an inner side of a peripheral edge portion of a resin molded casing, and an opposed rib is formed at an outer side of this peripheral edge portion by a generally channel-shaped groove. A gear in a gear mechanism of the actuator is made of a resin having self-lubricating properties. The actuator includes a brushless motor, a yoke molded of a resin having a cylindrical container-shape. A gear is formed integrally on a central portion of an outer end surface of the yoke. A fixing means for fixing the stator coil of the brushless motor to a housing or the board has a positioning structure for positioning the stator coil.

摘要： A power-window safety device which includes an annular magnet 21 mounted on a rotary shaft (9a) of a drive motor (9) for opening and closing a window glass of an automotive vehicle, and a magnetic flux sensor (20), disposed facing the annular magnet (21), for sensing a change of a magnetic flux developed from the annular magnet (21), which change in flux is caused by rotation of the rotary shaft (9a). The magnetic flux sensor includes Hall ICs (22A and 22B). An operational element (24A, 24B) performs a process of linearly approximating a sinusoidally varying voltage output from a Hall element (23A, 23B) which is provided in association with the operational element, and produces an output voltage (VA, VB) thus processed. Every angular position of the rotary output shaft, or every opening/closing position of the window glass, is detected over the range of one complete rotation on the basis of the output voltages (VA and VB) that are generated through the rotation of the rotary shaft (9a). A safety control operation is carried out, to prevent an object from being caught, on the basis of the detected position.

摘要： A power window drive device, including a motor, a worm wheel, a drive drum, and the like, whose manufacturing cost is reduced and which has a reduced size. A rotary shaft, driven by a motor, has a flange extending outward and a spline extending from the flange to the end of the rotary shaft. A drive drum, axially coupled to the rotary shaft, has a shaft hole with a spline and resiliently deformable hook pieces. The hook pieces engage the flange of the rotary shaft, thereby making the rotary shaft immovable in the axial direction. By inserting the end of the rotary shaft into the shaft hole of the drive drum, thereby coupling the splines and making the hook pieces engage the flange of the rotary shaft, the rotary shaft is made immovable with respect to the drive drum in both the axial and the circumferential directions. With this construction, there is no need of separate coupling elements, and the work to assemble the device is simplified.
