Filed: 1994-10-25
Abstract: PURPOSE: To provide a wide noise controlled area with small hardware as to the noise control unit which uses a control speaker and plural error detectors. CONSTITUTION: The control sound of the control speaker 2 is made to operate on the noise generated by a noise source 1 and error sounds are detected by the error detectors 3a-3n, whose detection signals are added. The output signal of an echo canceling filter 7 is subtracted from the addition signal and the result is inputted to an adaptive filter 8, a filtered X filter 6, and the error input of a coefficient update unit 9. The output of the filter 6 is inputted to the reference input of the coefficient update unit 9, which performs coefficient update operation according to LMS algorithm, etc., to update the coefficient of the adaptive filter 8 so that the error input signal is always small. The output signal of the adaptive filter 8 is inputted to the control speaker 2 and also inputted to the filter 7.  The same characteristics with the filter 6 are set in the filter 7, so a sound feedback loop is canceled.

Abstract: PURPOSE:To make it possible to detect the disconnection of the air feed and exhaust cylinder of a burner or the combustion failure thereof by comparing the detected values obtained by both a detecting element for the exhaust gas temperature of the air feed and exhaust cylinder and a detecting element for a flame electric current flowing through the main body of the burner with the respective set values to identify a combustion state. CONSTITUTION:When an air feed and exhaust cylinder 19 is disconnected, the detected value obtained by a temperature detecting element 27 is lowered to a first set value or below to cause a first comparator 32 not to produce an output. Therefore, an identifying circuit 38 identifies the disconnection of the air feed and exhaust cylinder on the basis of the comparative outputs from the first and a second comparators 32 and 35, and a combustion controlling circuit 44 stops combustion on a control signal via a first output line 45, while the first lamp 48 of an indicator 47 is lighted by a control signal via a second output lime 46 to indicate the disconnection of the air feed and exhaust cylinder 19. When combustion is put into a failure state, a flame electric current is decreased to a second set value or below to cause the second comparator 35 not to produce an output. Therefore, the identifying circuit identifies the combustion failure on the basis of the outputs from the first and the second comparators 32 and 35, and the combustion controlling circuit 44 stops the combustion on the control signal via the first output line 45, while the second lamp 49 of the indicator 47 is lighted by the control signal via the second output line 46 to indicate the combustion failure.
