  • Patent number: 7170263
    Abstract: An apparatus for controlling an on-vehicle generator is provided. The apparatus comprises a switching element, current detecting unit, setting unit and driving unit. The switching unit turns on/off an exciting current to an exciting winding of the generator, the switching element being driven responsively to a driving signal having an adjustable duty ratio. The setting unit sets the duty ratio based on (i) a difference between an output voltage of the generator and a target voltage value and (ii) a condition in which an electric load is disconnected from the generator, wherein the duty ratio is allowed to lower than a minimum value of the duty ratio depending on a generated state of the generator. The minimum value allows the exciting current to flow at a lower limit detectable by the current detecting unit, The driving unit drives the switching element based on the driving signal.

  • Patent number: 6101248
    Abstract: When a false signal received from a telephone set on a false originating side is detected, a call thereof is immediately disconnected. In reality, the system comprises a detecting portion 5A and a signal unit 4. The detecting portion 5A detects a false signal according to international telecommunication standard ITU-T No. 5 signal system. The signal unit 4 disconnects the call when the detecting portion 5A detects a false signal. The system further comprises a supervising means that supervises a false signal using toll-free service with a credit card system. A supervising unit 5 supervises whether or not a false signal is present. Corresponding to the supervised result of the supervising means, when a false signal is detected, the signal unit 4 immediately disconnects the call. Thus, the performance of the telephone exchange system is improved. In addition, the security of the system is improved.
