Title: Controlling circuit for combustion system
Inventor: CHIKIYUU TAKAO
IPC: F23N5/00
Filed: 1979-04-27
Abstract: PURPOSE: To simplify the check for maintenance and to enable to detect the operation of a pump driving circuit section and an electromagnetic pump, by giving on-off indication of an indicator in response to the pump operation.  
     CONSTITUTION: When an oscillation pulse is given to the primary coil 401 of a pulse transformer 40, a pulse signal is given via the secondary coil 402 to circuit E for controlling the width of an electromagnetic pump driving pulses. Thereupon, a driving pulse is impressed to the electromagnetic pump 57 and the fuel is ignited by spark discharge, whereby flame is produced at the burner section. Here, since an indicator 53 is connected in parallel to the pump 57, indicator 53 is lighted each time the pump 57 is set into operation. That is, since the indicator 53 is operated by a driving pulse afforded actually to the pump 57, frequency and period of the operation of the pump 57 can be detected correctly from an indicator 53.

Title: Wind comparator
Inventor: NISHIMURA KIYOSHI
IPC: H03K3/02
Filed: 1981-04-07
Abstract: PURPOSE:To maintain a function in a good condition and at the same time to stabilize the wind width for a wind comparator, by securing an agreement of the switching output through a logic gate circuit and supplying the wind comparator output caused by the agreement or disagreement of the switching output to a T-FF. CONSTITUTION:When an agreement is obtained between the output voltage Vo and the input signal voltage VIN, the output of a wind comparator 40 which is applied by the inverse output of an inverter 82 is set at an H level. This output resets a T-FF38, and accordingly, an output Q is set at L level to turn off a switching circuit 34. Then the holding voltage VH of a holding capacitor 26 is delivered through an output terminal 30 in the form of the voltage Vo. In case no agreement is obtained between the voltage Vo and VIN, the output of the comparator 40 is set at the L level. In this case, if a sampling control input Vs is applied to a control input terminal 36, a sampling pulse Ps is delivered from the T-FF38 to charge and discharge the capacitor 26. This charge and discharge is continued until the output of the comparator 40 is set at the H level. Thus the point sampling is possible.
