摘要： In a digital servo control system, the duty cycle of a pulse width modulated signal for controlling a drive motor is determined by digital numbers representing phase and/or speed errors preset into a memory and circulating counter. The circulating counter is driven by a clock signal which performs a number of cycles during each basic timing interval. A pulse width modulated signal is initiated by a timing pulse and is terminated by each return to zero of the most significant digit of the circulating counter. The time at which the most significant digit of the circulating counter returns to zero at the end of each of its cycles is determined by the number initially preset into it. The memory is gated with the output of a four-bit counter, which increments at the same rate that the circulating counter cycles, to either lengthen each pulse width modulated signal by one clock cycle or not. The number of times the pulse-width modulated signal is lengthened in a basic timing interval is proportional to the number preset into the memory. The contents of the memory and the circulating counter are periodically changed to correspond to detected speed and/or phase errors to update the duty cycle of the pulse width modulated control signal.

摘要： The duty cycle of a pulse width modulated signal for controlling a drive motor is determined by the content or numbers stored in a counter and representing phase and/or speed errors. The counter is driven by a clock signal which has a number of cycles during each cycle of the pulse width modulated control signal which is exactly equal to the capacity of the counter. The pulse width modulated signal is initiated by a timing pulse and is terminated by the return to zero of the most significant digit of the counter. The time at which the most significant digit of the counter returns to zero in each cycle is determined by a number initially contained in the counter. The content of the counter is periodically determined according to detected speed and phase errors to update the duty cycle of the pulse width modulated control signal.

摘要： According to the present invention, mistaken detection of a gas leak can be prevented even when using an appliance which has been newly installed in a dwelling receiving a gas supply, and whereby a gas leak can be detected rapidly, efficiently and accurately. The characteristics extraction means 5 extracts characteristics of a gas flow including a combination of the instantaneous flow volume data and the instantaneous flow volume time differential value, on the basis of the data obtained by the flow volume measurement means 1, pressure measurement means 2, instantaneous flow volume time differential operation means 3 and pressure time differential operation means 4. The leak detection means 7 compares the characteristics data for respective types of gas appliance or for a gas leak registered in the storage means 6 with the characteristics extracted by the characteristics extraction means 5, and if a matching is not achieved, further judges whether there is a flow volume variation or nozzle variation, and whereby it judges whether there is a gas leak or whether an unregistered appliance is in use. If occurrence of a gas leak, the warning means 9 issues a warning. If an unregistered appliance is in use, the characteristics data forming the basis of the judgment is registered as a new characteristics data in the storage means 6 by the characteristics data registration means 8.
