A reader/writer (RW) requires identification of anti-collision techniques used by IC cards (A, B, C, and D). The IC cards implement answers to the anti-collision technique identification requirement by the reader/writer at different timings respectively for respective IC cards among the IC cards which use different anti-collision techniques respectively. The reader/writer requires identifications of types of the IC cards in dependence upon the anti-collision techniques in response to the answers by the IC cards. The IC cards return identification data thereof in response to the card type identification requirements by the reader/writer for respective IC cards among the IC cards which use different anti-collision techniques respectively. The reader/writer identifies the types of the IC cards in response to the identification data of the respective IC cards.
摘要:
A reader/writer (RW) requires identification information pieces of respective plural IC cards (A, B, C). The plural IC cards return the respective identification information pieces in response to the requirement by the reader/writer. Logical addresses are assigned to some IC cards among the plural IC cards respectively to cause the reader/writer to select them in response to the return of the identification information pieces by the plural IC cards. The IC cards selected by the reader/writer are controlled. The reader/writer cancels the assignment of the logical address to one of the selected IC cards. The logical address, the assignment of which has been canceled by the reader/writer, is assigned to an IC card among the plural IC cards to which any logical address has not been assigned yet. The IC card to which the logical address has just been assigned is controlled.

An IC card whose state of usage can be judged by a user from an appearance of the card, and a relevant IC card system and method are provided. In an IC card fed electricity from an IC card reader-writer via feeding means using one of electromagnetic coupling and electrostatic coupling, and the IC card having an IC chip which communicates with the IC card reader-writer, the possible/impossible state of usage of the card by a user is determined using electric means for disconnecting or non-disconnecting the feeding means or providing another circuit and disconnecting this circuit, and appearance of the IC card is also changed at the time of the change caused by such electric means and thereby the state of usage of the card is indicated to the user.

A winding assembly includes: slot-housed portions housed inside each of the slots of the stator core so as to form pairs that line up in an inner layer and an outer layer relative to a slot depth direction; first return portions at a first axial end of the stator core that link end portions of the slot-housed portions housed in the inner layer inside each of the slots and end portions of the slot-housed portions housed in the outer layer inside the slots that are (N−M) slots away; and second return portions at a second axial end of the stator core that link end portions of the slot-housed portions housed in the outer layer inside each of the slots and end portions of the slot-housed portions housed in the inner layer inside the slots that are (N+M) slots away.

An automotive dynamoelectric machine that achieves disposing of permanent magnets and thickening of field coil wire by ensuring outlet space for field coil lead wires. In the dynamoelectric machine, trough portions are formed on portions of yoke portions between respective circumferentially adjacent claw-shaped magnetic pole portions. Magnet holders are disposed so as to span over all of the trough portions on a pole core body at a rear end excluding a predetermined trough portion, and permanent magnets are held in each of the magnet holders. A field coil lead wire is led out from the rotor so as to pass through the trough portion over which a magnet holder is not disposed.

An output voltage controller for an AC vehicle generator is proposed. The output voltage controller can easily suppress variation in rectified output voltage due to a switching surge without using a slope generation circuit in a voltage adjustment circuit. An excitation circuit that excites a field coil 13 includes a circulation element 31, a semiconductor switch element 33, an inductor 35, and transient voltage absorption means 40. The circulation element 31 is connected in parallel to the field coil 13. The semiconductor switch element 33 is connected in series with the field coil 13 and turned on and off by a voltage adjustment circuit 60. The inductor 35 is connected in series with the field coil 13 and the semiconductor switch element 33. The transient voltage absorption means 40 absorbs a transient voltage generated in the inductor 35 in association with the switching of the semiconductor switch element 33 between ON and OFF.
