    摘要： An image processing apparatus, for equally dividing an area of an arbitrary figure by pixel units by a number of parallel lines, which includes an input element for inputting a dividing number for a figure obtaining element which obtains a total number of pixels of the figure, a calculating element for calculating an initial ideal value by dividing the total number of pixels by the dividing number, a computing element for computing an ideal value of the number of pixels of a kth divided region in the figure using the initial ideal value and a sum of determined values of the numbers of pixels of a first to a (k−1)th divided region, and a determining element for determining a determined value of the number of pixels of the kth divided region such that an error between the determined value of the number of pixels of the kth divided region and the ideal value of the number of pixels of the kth divided region is minimized.

    摘要： A process for producing a styrenic polymer having a wide-spread molecular weight distribution, which comprises polymerizing a styrenic monomer or a styrenic monomer and a monomer copolymerizable with the styrenic monomer in the presence of 50 to 5000 ppm by weight of at least one compound selected from compounds having a dithiocarbamate group and sulfide compounds having at least one of an aryl group, an arylalkyl group and a thiazole group based on the total monomer to a final conversion of 40% by weight or more in the absence or presence of a radical initiator subjecting to a suspension polymerization, a batchwise bulk polymerization or a continuous bulk polymerization using a plug flow type polymerization reactor. According to the present invention, there can be provided a simplified process for preparing a styrenic polymer having a wide-spread molecular weight distribution.
