摘要： To provide an electrically powered brake system capable of performing a control of the braking force appropriate to a particular wheel rotational speed with high response and capable of being simplified in structure with no need to employ any hydraulic equipment and the related pipe lines, the electrically powered brake system includes an actuating unit 18 including a brake wheel 16 mounted on a vehicle wheel 1 and brake pieces 17 frictionally engageable with the brake wheel 16. A drive unit 19 is operable to translate a rotary output of an electric drive motor 20 into a rectilinear reciprocating motion by means of a ball screw mechanism 23, which rectilinear reciprocating motion is transmitted to the brake pieces 17 as a braking force. An operating unit 32 is operable to control the electric drive motor 20 according to manipulation of an operating member 31 such as, for example, a brake pedal. An anti-skid control device 35 is provided for regulating the braking force, exerted by the electric drive motor 20, in dependence on the number of revolutions of the vehicle wheel 1 during a braking effected by manipulation of the operating member 31. For a rotation detector 1 for detecting the number of revolutions of the vehicle wheel 1, the rotation detector 1 including a magnetic encoder 37 is employed.

摘要： A wind driven electrical power generating apparatus includes a rotor rotating by receiving wind force, a gear assembly having an input shaft connected to the rotor, a generator connected to an output shaft of the gear assembly, a sensor for detecting generating capacity of the generator and a controller for varying gear ratio of the gear assembly based on a signal from the sensor. In this construction, the controller controls so that the generator keeps rotating at around the lowest rotational speed within a range of rotational speed, the range being determined so as to include a maximum power operation region of the generator. Alternatively, the controller controls so that rotational speed of the output shaft of the gear assembly is adjusted to at around the lowest rotational speed within a range of rotational speed, the range being determined so as to include a rated power region as an upper operational limit.
