    Abstract: When noise is caused by the mechanical vibration propagated from the engine, the microprocessor calculates from the vibration frequency of the engine the secondary sound signal which is in antiphase with the noise and which is thus able to cancel out the noise, and supplies it to the loudspeaker which then emanates the secondary sound according to this signal. At this time,the divergence detection circuit monitors the incoming secondary sound signal, and when the secondary sound signal is remarkably increased, it decides that the noise is increased, and automatically stops the secondary sound output from the loudspeaker. Therefore, it can be prevented that the noise is reversely increased by the secondary sound.

    Abstract: A signal lamp apparatus with a lamp burnout detecting circuit has a right turn signal lamp group and a left turn signal lamp group which are connected to a power source through a turn signal switch and a relay contact coupled in parallel with a burnout detecting resistor. Each of the lamp groups includes a plurality of signal lamps connected in parallel with one another. The apparatus includes a comparator which produces an output signal when the voltage across the signal lamp group is higher than a predetermined voltage, and a device which produces a burnout signal when the comparator has an output signal after lights-out, for example, after 20 to 100 m sec since the relay contact is opened. With such an arrangement, the burnout of the signal lamp or lamps may be detected while the signal light lamp group is flashing.

    Abstract: A signal converter for converting a varying input voltage, such as an output signal from a detector, into an output voltage in absolute value, including an operational amplifier, a comparator and two groups of electronic switches. The comparator compares the varying input voltage to a predetermined reference voltage. The operational amplifier has negative and positive input terminals and generates an output voltage signal in proportion to the difference between the voltages applied to its two input terminals. When the input voltage is less than the reference voltage, one group of electronic switches turns on, so that the input voltage and the reference voltage are applied to the negative and the positive input terminals of the operational amplifier, respectively. When the input voltage is greater than the reference voltage, the other group of the electronic switches turns on, so that the input voltage and the reference voltage are applied to the positive and the negative input terminals of the operational amplifier, respectively.
