Latest Patents

Suganuma holds a patent for a volume control apparatus. This invention features a master volume control resistor that is regulated by a motor. The control circuit for the motor includes a presettable-variable resistor and a slave-variable resistor, which is driven by the motor's output shaft. A first comparator connects the presettable-variable resistor and the slave-variable resistor across suitable supply voltages. The motor control discriminator circuit operates the motor in either direction to adjust the master volume control and the slave-variable resistor until they are substantially equal. When the resistance of the slave-variable resistor approaches that of the presettable-variable resistor, the output of the master volume control is connected to an output speaker via a relay circuit.
