Title: Automatic gain control circuit
Inventor: KAGAWA MASATO
IPC: H03G3/30
Filed: 1985-05-29
Abstract: PURPOSE:To widen the range of automatic gain control, and also to change easily a compression range by providing a pair of reverse conductive type FETs whose mutual conductive channels are connected in series and inserted, and a pair of means for generating a control voltage in accordance with a DC component of an amplied input, on a signal line of an amplified output. CONSTITUTION:A TR4 for a current/voltage conversion use 1 is provided on the output of a general purpose amplifier 1, and in its output line, a pair of FETs5, 6 which are a reverse conductive type each other are inserted so that the mutual conductive channels are connected in series. An amplifier 9 fetches only a DC component from a bias of the amplifier 1 and feeds a reference potential to the FETs5, 6. To an emitter of a TR10, namely, a reference potential A', a variable resistance 11 is connected. As a result, an amplifier 12 and 13 output voltages of (reference potential A'+set potential) and (reference potential A'-set potential), respectively, and its output is inputted to the FET5 and 6, respectively. It becomes possible to change a compression range by moving the set potential by the variable resistance 11. When an input signal of the amplifier 1 decreases, the reference potential drops, a drain-source voltage of the FETs5, 6 increases, the DC potential of an output OUT is kept constant, and an AC signal is kept constant.

Filed: 1988-05-13
Abstract: PURPOSE:To regulate the cooling degree of a heat exchanger to permit the reduction of after-heating upon re-supplying of hot-water by setting the number of rotation of a combustion fan in accordance with the combustion range of a burner immediately before stopping the burning operation thereof. CONSTITUTION:Until a time (to), a combustion fan 8 is operated through air-fuel ratio mode, in which the number of rotation thereof is set in accordance with the combustion range of a burner. At a time (to), a water flow switch 10 for closing a hot-water supplying cock 4 is put off and the burner 5 is put OFF. In this case, the temperature of hot-water remaining in a heat exchanger in increased by after- heating phenomenon due to remaining heat in a combustion chamber and, therefore, only the combustion fan 8 is operated until a predetermined time (te). The amount of remaining heat in the combustion chamber is related to a combustion range Qg until hot-water supplying operation is stopped. When the combustion is stopped when the combustion range Qg of the burner is 75-100%, the value of the number of rotation of the fan is set at a high value N1, the number of rotation of the fan is set at the value of N1 when the combustion range is 50-75%, and the number of rotation of the fan is set at the value of N3 when the combustion range Qg is 50% or lower. The number of rotation of the fan is increased as the combustion range Qg of the burner upon stopping the burning operation thereof is large.
