摘要:
A product identification method of one embodiment of the invention includes the steps of providing a product with an information nucleic acid having a segment of known base sequence randomly selected for the product, extracting the information nucleic acid from the product, amplifying the information nucleic acid by a polymerase chain reaction; and determining a base sequence of the information nucleic acid to identify the product by the base sequence of the information nucleic acid.

In a general-purpose induction motor, a three-phase induction motor 10 is provided with a terminal box containing terminals for electrical connection and a conversion module 30 contained in the terminal box and coupled to the three-phase induction motor. The conversion module has a function of converting a plurality of types of single-phase AC into a single type of three-phase AC. With this structure, the general-purpose induction motor can be used with the single-phase AC.
摘要:
A photographic light-sensitive element for the color diffusion transfer process which comprises a support having thereon at least one light-sensitive silver halide emulsion layer with at least one of the silver halide emulsion layers having associated therewith a dye releasing redox compound represented by the following general formula:D-Redox Moietywherein D represents a dye moiety and Redox Moiety represents a group represented by the following general formula (I): ##STR1## wherein X.sup.1 represents an --SO.sub.2 -- group or a --CO-- group; R.sup.1 represents an unsubstituted straight chain alkylene group having 2 or more carbon atoms or an unsubstituted branched chain alkylene group having 2 or more carbon atoms with the proviso the branched chain alkylene group is incapable of forming an acetal linkage; R.sup.2 represents an alkyl group; and Y represents an o- or p-hydroxyarylsulfamoyl group having a ballast group bonded thereto.
摘要:
A 2-alkoxyalkoxy-5-nitrobenzenesulfonic acid or a salt thereof represented by the following general formula (I): ##STR1## wherein R.sup.1 represents an alkylene group having 2 or more carbon atoms; R.sup.2 represents an alkyl group; and M represents an inorganic or organic cation. The compound represented by the general formula (I) is useful as an intermediate for a dye releasing redox compound which is suitable for use in the color diffusion transfer process.
