Title: Combustion unit control circuit
Inventor: TERASAKA AKINORI
IPC: F23N5/18
Filed: 1982-08-19
Abstract: PURPOSE:To enable a stable combustion by a method wherein a combustion starting signal is fed out after the number of rotation of a fan is stabled in a control circuit or combustion unit such as a forced intake and discharging type gas boiler etc. CONSTITUTION:An operation switch is turned on and a motor (FM) is started to rotate at a high speed. When the motor (FM) is started to rotate, a frequency of a pulse generating circuit 3 is increased and capacitors C1 and C2 increase their potentials. In an amplifier OP1, a difference with an output from a speed setting circuit 4 is decreased down to the desired value, thereby the motor FM continues to rotate at the desired high rotation. In turn, in a combustion starting control circuit 7, the capacitor C2 is charged at a slower rate than that of the capacitor C1, the potential reaches to the desired value V4 after a time of t1 from the starting of operation, a positive (high) output is fed out from a comparator CP, this state is judged by the main control circuit 8 under the condition of OFF of a transistor Tr5 and then a combustion starting signal S is produced. Therefore, at this time, since the number of rotation of the fan motor FM is stabled, the burner shows a stable combustion under a proper volume of combustion air.

Title: Comparison voltage generating circuit and voltage detecting circuit using said circuit
Inventor: KOKUBU HITOSHI
IPC: G11C5/14
Filed: 1987-06-12
Abstract: PURPOSE:To obtain a comparison voltage generating circuit which can generate minutely and with good linearity a control of a voltage of a node, and a voltage detecting circuit, by providing a means for not controlling a voltage by a resistance division but controlling the voltage by capacity division. CONSTITUTION:Since a node N10 is an output node of a constant-voltage generating circuit 10, a prescribed voltage VN10 is applied. When an input signal line BIT0 is in an H level, a transistor TR TP0 and a TR TNO become OFF and ON, respectively, therefore, a node N20 becomes a ground level. When the BIT0 is in an L level, the TR TP0 and the TR0 become ON and OFF, respectively, and the potential of the node N20 becomes a node N10=VN10. Signal lines BIT1, BIT2 also execute the same operation. Accordingly, by setting the BIT0-2 to an H or L level, the nodes N20-22 can be set to zero V or VN10. By setting in advance a capacity ratio of capacitors C0-C2 to 1:2:4, a voltage level VN11 of a node N11 can be set to eight stages.
