    摘要: A control system is disclosed wherein the dialing of a specific number as the first digit is prevented. The system comprises a dial tone detector which detects a dial tone sent from a telephone exchange to a telephone set when a call is originated from the telephone set by off-hooking its handset, a dial pulse counter for sequentially counting the number of the dial pulses detected by the dial pulse detector, and circuitry responsive to signals from the dial tone detector and dial pulse counter for interrupting the loop if a number is dialed before reception of a dial tone. Additionally, when the output of the counter corresponds to the forbidden number, a talking or speech interruption control unit is operated to interrupt the talking or speech loop.

    摘要: In a speed control system for vehicles, a speed difference calculation circuit calculates an absolute value of a time difference between a predetermined period of time corresponding with a desired speed and an instant period of time corresponding with the actual speed, an acceleration calculation circuit calculates an absolute value of a time difference between the respective instant periods of time, and a correction signal generator calculates a sum of the absolute values in consideration with the actual speed when each sign of the calculated time differences is positive or negative and calculates a difference between the absolute values in consideration with the actual speed when respective signs of the calculated time differences are opposite to each other. The signal generator selectively produces correction signals related to the calculated sum and the calculated difference. A distribution circuit produces a control signal in response to the respective correction signals, and an actuator controls the opening angle of the engine throttle in response to the control signal.

    摘要: In a speed control system for automotive vehicles, a first time difference between values of a timing signal responsive to the actual speed of the vehicle and a command signal indicative of a desired speed is calculated to produce a first differential signal indicative of an absolute value of the first time difference, and a second time difference between respective values of the preceding and following timing signals is calculated to produce a second differential signal indicative of an absolute value of the second time difference and a sign signal indicative of one of positive and negative signs of the second time difference. The absolute value of the second differential signal is adjusted to a smaller value when the sign of the sign signal changes within a duration defined by the preceding and following timing signals, the absolute value of the first differential signal is adjusted in accordance with either one of the absolute and smaller adjusted values of the second differential signal in relation to the sign of the sign signal to produce a correction signal indicative of the adjusted value of the first differential signal, and a control signal is produced in response to the correction signal to control the fuel supply into the prime engine of the vehicle.
