  • Transmission of FM video signals over various lines
    Patent number: 5818127
    Abstract: An apparatus for electrical line communications using FM video modulation, includes FM video modulation circuits and an impedance matching coupler at each of two or more locations along a pair of lines. The impedance matching couplers provide impedance matching, utilizing an air-core preselected frequency bands, sufficient to allow low-loss transmission of frequency modulated video signals. The coupler further eliminates noise and is matched resistively to the characteristic impedance of the line at the preselected frequency bands. A transmitter, receiver and associated circuits may also be provided at each location along the lines. The FM video modulation circuits, in combination with phase linear coupling techniques, provide for hi-fidelity video transmission over existing electrical lines, such as residential AC power wiring.

  • Power supply circuit for a printer
    Patent number: 5814978
    Abstract: A power supply for use in a printer provides a current progressively small with increasing transfer roller impedance. A reference current section RC sets a voltage Vr indicative of a reference current Ia of an output current Iout of the power supply PS. A voltage generator VG provides an output voltage Vout of the power supply PS. A voltage monitor VM monitors the output voltage to provide a voltage-monitoring signal Vm to an operational section E. The operational section E determines a correction value of the output current Iout on the basis of the voltage Vr and the voltage-monitoring signal Vm. The correction value is progressively small as the voltage-monitoring signal Vm increases.
