Latest Patents
Sanada's latest patents include innovative methods and apparatuses that improve the performance of image forming devices. One of his notable patents is for an "Image forming apparatus and method of controlling heating of fixing unit therein." This invention allows a control mechanism to inform an engine control unit about user operations without waiting for a general-purpose communication line to open. Upon receiving the user operation signal, the engine control unit promptly heats the fixing unit, enhancing the overall efficiency of the apparatus.
Another significant patent is for an "Image forming apparatus and power control method." This invention involves multiple heating units that generate heat through alternating-current power supplied from corresponding power supply units. The heat is then used to fix toner images on recording paper. The system includes power control units that manage the alternating-current power to each heating unit, while detecting units monitor the reference phase of the waveform of the power. A control unit then individually regulates the power control units based on the detected signals.
