Abstract: <P>PROBLEM TO BE SOLVED: To obtain large output sound pressure even when the vibration amplitude of a diaphragm is small.  <P>SOLUTION: A sound signal to be reproduced is input from an input terminal 10. A high frequency signal with fixed amplitude is output at a fixed frequency from a high frequency signal source 12. The frequency of the high frequency signal is higher than an audible frequency and is set to 10 to 1,000 times e.g. as much as the upper limit frequency of the sound signal to be reproduced. An amplitude modulation circuit 14 modulates the amplitude of the high frequency signal by the sound signal. The amplitude-modulated high frequency signal is amplified by an amplifier 16 to drive a speaker 18. The speaker 18 is a speaker of a type that the displacement amount of the diaphragm follows an application voltage and is composed of an electrostatic speaker, a piezoelectric speaker, or the like.  <P>COPYRIGHT: (C)2009,JPO&INPIT

Abstract: <P>PROBLEM TO BE SOLVED: To restrain reduction in an engine speed and the occurrence of a stall in an internal combustion engine, when combustion of an air-fuel mixture becomes unstable in a combustion chamber, after resuming fuel injection, when abnormality determining processing is interrupted in response to stopping of a fuel cut.  <P>SOLUTION: When the abnormality determining processing is interrupted in response to the stopping of the fuel cut, an EGR valve 33 put in a state of opening more than usual by the processing, is returned to original opening (full closure), and the fuel injection of an engine 1 is resumed. Here, an EGR passage 32 is put in a state of being filled with air when performing the abnormality determining processing. When the EGR valve 33 is returned to a full closure state, a response delay is caused in a flow rate change in the air flowing in an intake passage 4 from the EGR passage 32 in response to its return, the air excessively flows in the intake passage 4. As a result of it, the suction air volume of the engine 1 becomes excessive to a fuel injection quantity after resuming the fuel injection. For restraining such an excess of the suction air volume to the fuel injection quantity, a quantity increase in the fuel injection quantity is corrected.  <P>COPYRIGHT: (C)2009,JPO&INPIT
