Abstract:
The invention provides a biologically active substance transfer sheet which can be formed with simple steps, a cell culture kit which comprises a cell culture plate and a biologically active substance transfer sheet, a producing method therefor, and a method for screening cell culture conditions with cells. The transfer sheet is prepared by providing biologically active substances having biological activity in plural areas on a sheet base, and biologically active substances are supplied from the sheet to culture regions provided on the plate.
Abstract:
A recording apparatus includes a recording head for performing recording on recording paper, the recording head having three or more types of inks of different densities but of the same color. A combination of the inks used to record a pixel of a grayscale image, which is to be recorded on the recording paper, is decided based upon the pixel by a data distribution unit which refers to ink density data and combination data. Recording by the recording head is controlled, based upon the combination of inks decided, by a unit which controls the recording head and paper feed.
Abstract:
An optical recording medium is disclosed which comprises a substrate (101) containing a polycarbonate resin and a recording layer (102). The substrate contains copolycarbonate resin having constitutional units represented by the formulae (x) and (y) [wherein Z of the formula (x) is a direct bond, alkylidene, -O-, -S- or -SO2-; X is H, halogen, alkyl, aryl, aralkyl, alkoxy, aryloxy or aralkyloxy; R1 is H, alkyl or aralkyl; m is an integer of 1 to 3; Y of the formula (y) is alkylidene, aryl-substituted alkylene, aryl, -O-, -S-, -CO- or -SO2-; and each of R2, R3, R4 and R5 is H, halogen or alkyl].
