摘要:
The present invention provides a novel method of producing the 12-membered ring macrolide compound 11107D having an antitumor activity by biological transformation. Starting material which is the 12-membered ring macrolide compound 11107B represented by the formula (I) is incubated in the presence of a strain belonging to the genus Mortierella, the genus Streptomyces or the family Micromonosporaceae (for example, Streptomyces sp. AB-1704 strain (FERM BP-8551)), each of which has the ability of transforming the 12-membered ring macrolide compound 11107B into a 11107D substance represented by the formula (II), or a preparation of its cultured myceha and oxygen, and then 11107D substance which is a target material is collected from the treating solution.

摘要:
A quantizing unit, error detector, error diffusion matrix, and adder quantize a pixel of interest of an input image by an error diffusion method. A calculation unit and gain adjuster calculate a value to be added to the pixel of interest with reference to quantized pixels. The adder adds the calculated value to the pixel of interest. A control unit controls the calculation of the gain adjuster.
摘要:
A halftone screen which is applicable to a low-resolution electrophotographic printer is created. Hence, dot-lattice points arranged in a predetermined region are displaced using rotation processing, the predetermined region is partitioned into polygons each of which surrounds the dot-lattice point. Then, a threshold matrix used to grow a halftone dot, which is surrounded by each polygon, in a direction of the displacement is generated.
