    摘要： The invention makes it possible to perform effective A/D conversion on pixel signals read from a pixel array part, to achieve a reduction in power consumption and reductions in the size and the price of an image pickup device as well as simplification of the construction of the device, and to realize a high-quality image output. The device includes an pixel array part having a plurality of unit pixels, a CDS (correlated double sampling) circuit, and an A/D converter. A pixel signal read from a pixel array part via a signal line is subjected to CDS processing (noise elimination processing) in the CDS circuit, and then this pixel signal is inputted into the A/D converter which performs A/D conversion on the pixel signal. The A/D converter includes a ΔΣ modulator and a digital filter to perform highly accurate A/D conversion. The invention can also be applied to a construction in which an A/D converter is provided at the front stage of the CDS circuit.

    摘要： A device for producing a fibrous sheet, including a water squeezing section which squeezes the dispersion medium from a dispersion to generate a web, and a drying section which dries the web to generate a fibrous sheet, the water squeezing section having multiple first fabric sheets arranged longitudinally along the transport direction of a web substrate that is partway through web generation, and water squeezing units which are provided beneath the multiple first fabric sheets and squeeze the dispersion medium from the dispersion, and in the water squeezing section, a continuous sheet is positioned so as to extend over the upper surface of the multiple first fabric sheets, and the dispersion is discharged onto the upper surface of the continuous sheet.
