  • Patent number: 9967502
    Abstract: In a CMOS image sensor, a plurality of bias circuits are dispersedly arranged in an arrangement region of column circuits corresponding to each column of a pixel array. Each bias circuit generates a bias voltage on the basis of a reference current which has been input and supplies the generated bias voltage to the corresponding column circuit 10 which is arranged in the vicinity. Thereby, luminance unevenness of a picked-up image caused by an IR drop of a ground wire for the column circuits is reduced.

  • Patent number: 9423412
    Abstract: Unlike conventional reagent storing means of an analyzing unit having a cold-storage function, replacement reagent storing means having no cold-storage function requires reagent management of a higher order. An automatic analyzer is provided that manages the placing elapsed time for a reagent vessel in replacement reagent storing means 2, compares the placing elapsed time for the reagent with a permissible placing limit value stored as one of analysis parameters for each analysis item, and determines as to whether or not the placing elapsed time exceeds permissible limit value. In this way, the analyzer prevents the degradation of the reagent and automatically transfers the reagent to an analyzing section for performing measurement.
