Abstract: In a developer cartridge, the base portion is fixed to an outer surface of the one side of the frame, and extends from one end thereof to another end thereof in a second direction orthogonal to the first direction. The first extending portion extends from one end thereof to another end thereof in the first direction. The one end of the first extending portion is connected to the another end of the base portion. The second extending portion extends from one end thereof to another end thereof in a direction opposite to the second direction. The one end of the second extending portion is connected to the another end of the first extending portion. The input portion is connected to the another end of the second extending portion and inputs electrical power from an external device. The electrode is deformable such that a distance between the base portion and the second extending portion becomes smaller.

Abstract: A supporting element or core stack for an electric winding, in particular for a stator of a turbogenerator, includes a supporting surface to which an electric conductor can be attached. The supporting surface is provided with a coating for corona shielding. A turbogenerator has the supporting element. A method of producing a corona shield for an electric winding disposed on a supporting element, includes providing the supporting element with a coating for corona shielding.

Abstract: A stator assembly operated in a 2-phase drive manner including first and second stator coils wound in a star shape with a plurality of projections and a plurality of grooves, and arranged with a predetermined phase difference; and an annular supporting body into which the first and second stator coils are inserted for supporting the coils, insulating them from each other. Each stator coil includes four projections and four grooves, and there is a phase difference .theta. between the first and second stator coils, the difference determined by the following equation: .theta.=360/2P.+-.360/P, wherein P denotes the number of a rotor's magnetic poles.

Abstract: Transducer, in particular clockwork driving motor, comprising a stator (2) formed of two stator parts (16 and 26) and three cores (18, 19, 20) connecting respectively three magnetic poles (28, 29, 30), defined by the first stator part (16), to the second stator part (26) used to close the magnetic paths of the transducer. The coils (22 and 24) are used to supply the transducer to drive in rotation respectively the two rotors (4 and 6). The coil (23) is connected to detection means (72) used for detecting the rotation of one or other of the two rotors (4 and 6), and in particular, for detecting zero crossing of the induced voltage (or similarly of the induced current) in the coil (23). Detection of zero crossing of the induced voltage is used to provide input signals to the supply means (70) to control driving of the rotors (4 and 6) in an efficient and reliable manner, in particular in a rapid or continuous operating mode, whether in a forward or backward rotational direction.

Abstract: A motor/generator that is operable in an inductive mode during a startup phase and in a synchronous mode thereafter. Superconductor material is included in either the stator or the rotator and a magnetic field generator is included in the other of these two members. Induced fields in a torque-shield provide coupling between the stator and the rotor during the startup phase and then a trapped field in the superconductor provides coupling between the stator and the rotor thereafter.
