Latest Patents

Fukagawa's latest patents include a Switching Element Driving Device and Method, which features a slew rate regulation circuit. This circuit varies the slew rate of a voltage outputted to a DC motor through an N-channel MOSFET. The regulation circuit effectively lowers peak levels by dispersing frequency components of switching noise, which occurs in a frequency range higher than that determined by a carrier frequency. Another notable patent is the Differential Communication Device. This device connects two transmission lines for a predetermined time through a diode when a transmission signal changes from a high level to a low level. The arrangement of the diode ensures that it turns on when the potential of the high-side transmission line exceeds that of the low-side transmission line, thereby limiting the peak wave level of the ringing.
