Latest Patents

Kawazoe's latest patents include a voltage to pulse-width conversion circuit and a current driving circuit with a CMOS inverter. The voltage to pulse-width conversion circuit features a counter that counts a reference frequency signal, producing a multi-bit digital value. This digital value is then converted into an analog signal by a digital/analog converter. A voltage comparator compares the output of the digital/analog converter with a control signal, resulting in a pulse width modulated output signal with a predetermined duty cycle ratio. The current driving circuit, which includes a CMOS inverter, a Darlington amplifier, and a semiconductor switch, enables a printing head to operate with low power consumption. The Darlington amplifier, consisting of multiple bipolar transistors, is connected to the output of the CMOS inverter. The semiconductor switch controls the bias voltage of the Darlington amplifier in synchronism with an input signal to the CMOS inverter.
