Filed: 1990-11-20
Abstract: PURPOSE:To easily confirm the external line incoming mode by providing a control means to control a display means in response to the line wire incoming mode stored in a storage means to the exchange. CONSTITUTION:A CPU 4 reads a setting data of an external line (i) of a line wire incoming mode setting memory in a RAM 7 of a master set 1 so as to discriminate whether or not the incoming call mode to the line wire (i) is the usual incoming mode and repeats it for a prescribed period in the case of the usual incoming call mode.

Inventor: SHINOHARA SENZOU
IPC: F23N3/08
Filed: 1993-12-16
Abstract: PURPOSE:To enable a combustion to be always kept at the most suitable mixing ratio by a method wherein a driving current attained when the number of revolution of a fan motor is coincided with a predetermined number of revolution is defined as a reference current value of the fan motor and subsequently the fan motor is controlled in such a way that this reference current value may be maintained. CONSTITUTION:A fuel control part 15 feeds a voltage setting signal giving a reference current to a voltage comparing part 12, wherein this voltage setting signal is compared with a DC voltage outputted from a current converting part 11 and then its error signal is sent to a pulse width control part 10. The pulse width controlling part 10 controls a pulse width of a pulse waveform signal outputted in response to the error signal sent from the voltage comparing part 12, causes a DC voltage outputted from the DC converting part 11 to be variable, thereby a feed-back control is carried out in such a way that the driving current for the fan motor 7 may coincide with the reference current. As a result, the driving current for the fan motor 7 is kept at the reference current corresponding to the set number of revolution giving the most suitable air feeding amount and then combustion can be always carried out under the most suitable mixing ratio.
