In an electric power generating apparatus for dispersed power supply using a permanent magnet type electric power generator having many kinds of windings in order to obtain the maximum output by force of wind without using PWM converter, there is a problem that gap magnetic flux of the permanent magnet type electric power generator is demagnetized to decrease the internal induced voltage because alternating current output of the permanent magnet type electric power generator is lagging current. In an electric power generating apparatus for dispersed power supply including a permanent magnet type electric power generator having a plurality of windings inducing different effective values of induced voltages and individual rectifiers for rectifying alternating current outputs of the permanent magnet type electric power generator, a capacitor is connected in series between the individual rectifier and the alternating current output terminal of the winding inducing higher effective value of induced voltage among the plurality of windings in a manner that serial impedances of the capacitor and the permanent magnet type electric power generator become capacitive within the range of rated rotational speed of said permanent magnet type electric power generator.

An apparatus is provided for actuating a bicycle hub brake of the type having a fastening bracket adapted to be nonrotatably mounted relative to a bicycle frame, a brake drum, and a brake mechanism adapted to apply a braking force to the brake drum, wherein the brake drum rotates integrally with a bicycle hub around a hub axle. The apparatus comprises an actuating member and a rotating member. The actuating member is structured to be movably mounted relative to the fastening bracket for actuating the brake mechanism, and the rotating member is structured to be rotatably mounted relative to the fastening bracket independently of the actuating member. The rotating member includes an actuating member moving unit for moving the actuating member. The rotating member also includes a cable winding surface to wind a brake actuating cable thereon.

An apparatus for mounting a brake control element to a bicycle hub brake comprises a rotating member structured to be rotatably mounted relative to a fastening bracket so that rotation of the rotating member actuates a brake mechanism, wherein the rotating member includes a brake control element mount. The rotating member also has a cable winding surface to wind a brake actuating cable thereon. A brake control element attachment unit is structured to be attached to the brake control element mount, wherein the brake control element mount includes a locking structure such that rotation of the brake control element mount relative to the brake control element attachment unit locks the brake control element attachment unit to the brake control element mount.

An internal gear shifting hub includes a motor that assists in gear shifting operations. The internal gear shifting hub is mounted at on rear portion of a bicycle frame and includes a hub shaft, a drive cylinder, a hub shell, a power transmitting mechanism, a shift mechanism and a generator mechanism. The drive cylinder and hub shell are both rotatably mounted to the hub shaft. The power transmitting mechanism is mounted between the drive cylinder and the hub shell and transmits rotational force from the drive cylinder to the hub shell via one of a plurality of force transmission paths. The shift mechanism shifts between the plurality of transmission paths. The generator mechanism is mounted alongside the power transmitting mechanism inside the hub shell and generates electric power via the rotation of the hub shell to power the motor.
