    摘要: The present invention relates to a segregation reducing agent consisting of curdlan and alkaline materials and a hydraulic composition containing the segragation reducing agent, particularly, the present invention relates to the segregation reducing agent prepared by alkalifying a curdlan-producing fermentation broth per se or a curdlan powder with an alkaline material, and also relates to hydraulic compositions, concrete and mortar, comprising the segregation educing agent. This segregation reducing agent can provide a great segregation reduction effect for hydraulic compositions even at its small amount as well as guarantee the strength, filling ability and fluidity.

    摘要: An image sensor includes an active pixel and a black pixel. The active pixel has a first signal gain and a first dark signal level, and the black pixel has a second signal gain and a second dark signal level. At least one of the first and second signal gains is adjusted such that the first and second dark signal levels are substantially equal for minimizing image defects in the image sensor.

    摘要: Unit pixels, image sensors and methods for fabricating the image sensor are provided. A unit pixel includes: a photodiode for accumulating photocharges; a floating diffusion region for detecting the photocharges accumulated in the photodiode; a reset element for periodically resetting the floating diffusion region; a drive element for amplifying the photocharges accumulated in the floating diffusion region; a selection element for selecting the unit pixel; and a silicide layer formed on top surfaces of the transfer gate. The photocharges are transferred to the floating diffusion region via a transfer gate.
