摘要： In a record player, a turntable is rotatably mounted on a base, and a rotor structure, such as an annular magnet, is mounted on the turntable and cooperates with a stator aperture mounted on the base to cause the turntable to rotate. The annular magnet is preferably a rubber magnet formed by molding rubber mixed with a ferrite powder. For the sake of stability, the annular magnet is in close proximity to the circumference of the turntable. The stator aperture preferably includes bobbins on which stator coils are wound, and arcuate tongues, integral with the base, on which the bobbins are arranged and which form magnetic cores for the stator coils.

摘要： A current mirror circuit comprised of three transistor devices, each transistor device including an input terminal and first and second output terminals. Two of the devices have their input terminals connected together and one output terminal of each device is connected to a respective current output terminal. The other output terminal of each device is adapted to be supplied with an operating voltage. Each of the first and second transistor devices is formed of at least a pair of transistors connected in Darlington-type configuration. In one embodiment, these Darlington-connected transistors are of complementary types. The third transistor device has its input terminal coupled to one of the current output terminals and one of its output terminals coupled to the common-connected input terminals of the first and second transistor devices. The remaining output terminal of the third transistor device is coupled to a reference potential. The third transistor device also is formed of at least a pair of transistors connected in Darlington-type configuration. In one embodiment, a current feedback resistor is connected to one output terminal of each of the first and second transistor devices. In another embodiment, each of the first and second transistor devices includes one transistor whose base is supplied with current by another transistor, this base being coupled to the current output terminal by a bias resistor.
