Abstract: A highly reliable connection structure of a bundle of more than two coil leading-out wires and a wire bundling terminal is provided by contacting and fixing at least a part of a circumferential surface of each of the coil leading-out wires to an inside wall of the wire bundling terminal. Further, a small size motor and an alternator for a vehicle utilize the connection structure.

Abstract: In a facsimile communication system, a user's terminal facsimile apparatus stores a plurality of character strings each composed of instruction words and data to be sent to a host apparatus for identifying one of communication services offered from the host apparatus. Accordingly, when one of the stored character strings is selected and executed, the corresponding communication service is offered from the host apparatus to the user's terminal facsimile apparatus. The character string may be produced by actually communicating with the host apparatus so that a transmission timing of the data in the character string can be precisely matched with what is required by the host apparatus.

Abstract: Plural thin plate projecting portions are integrally and projectingly provided on an outer peripheral portion of a side plate member of a bobbin. Each of the thin plate projecting portions comprises a circumferential rib, a slit portion and a reinforcement rib. The circumferential rib is provided on an outer peripheral face of the thin plate projecting portion of the bobbin and then a gap is formed between a claw-shaped magnetic pole of a rotor core and the thin plate projecting portion. A varnish material etc. is caused to adhere to and harden in this gap. By filling a root portion of the claw-shape magnetic pole of the rotor core with varnish material, the resonance vibration in the rotor core can be restrained. As a result, an alternating current generator for use in a vehicle having the small magnetic noise can be obtained.
