  • Publication number: 20110109710
    Abstract: First humidified gas is supplied from a first supply port to a sheet to be conveyed, thereby increasing the moisture content of the sheet. Simultaneously, second humidified gas is supplied to a space where nozzles of the inkjet recording head are exposed, from a second supply port provided at a position closer to the inkjet recording head than the first supply port, thereby increasing the atmosphere humidity of the space. The part of the sheet of which the moisture content has been increased is made to enter the space where the atmosphere humidity has been increased, and recording is performed by the inkjet recording head.

  • Patent number: 7289054
    Abstract: Each of plural sigma-delta modulators having a sampling capacitor, an integrator, and a quantizer are connected to each other in parallel. Each of the sigma-delta modulators conducts parallel oversampling in which an analog input signal is sampled by a sampling capacitor, and the sampling result is quantized by the integrator and the quantizer. Then, the quantized values of the sigma-delta modulators are added to obtain MSBs, the residue values of the integrators after quantizing in the respective sigma-delta modulators are added, and the addition result of the residue values is converted analog-to-digital to obtain LSBs.
