A set pattern image with no displacement is recorded onto recording paper. In this set pattern image, the centers of auxiliary patterns are displaced in an auxiliary scan direction off a referential straight line passing through the centers of primary patterns. The image forming apparatus causes the set pattern image to be read, measures the displacements of the auxiliary patterns in the auxiliary scan direction off the referential straight line, and compensates for the displacements, such as by adjusting writing timings in the auxiliary scan direction so that the displacements become zero.

Assuming the photosensitive drum for black as a reference, the phase of the adjacent photosensitive drum for cyan leads by about 60 deg. Similarly, the phase of the photosensitive drum for magenta leads by about 120 deg., and the phase of the photosensitive drum for yellow leads by about 180 deg. The phase of each photosensitive drum is shifted to thereby make it possible to shift the phase of driving unevenness. By shifting the phase, even the distance between adjoining transfer positions corresponding to the image forming stations is set shorter than the circumference of the photosensitive drum, the variation of each photosensitive drum due to driving unevenness with respect to the printing medium passing through the transfer position can be kept congruent with the others.

A registration pattern data generating portion is configured of a pattern set data generator for rough order error estimation and a pattern set data generator for fine order error estimation. When an error is estimated, a pattern set for rough order error estimation is checked first so as to roughly determine the size of the error and then another pattern set for fine order error estimation is checked so as to finely determine the size of the error. Thus, checking the two types of pattern sets makes it possible to exactly recognize the error in rough and fine units, providing fast and exact error determination.

The purpose of this invention is to provide a water-based anti-fouling paint composition which has excellent anti-fouling effects in seawater and which has minimal effect on the environment and on the operators because organic solvents are essentially not included. The purpose is accomplished by providing a water-based anti-fouling paint composition that contains a metal cross-linked acrylic water-based emulsion composition containing a divalent metal compound and dithiocarbamate compound, and which essentially does not require volatile organic solvents.

摘要:
A compound of the following formula: Ea—La—X—Lb—Eb in which each of Ea and Eb independently is a group having oxidation-reduction activity and having a conjugated system in its group; X is a divalent cyclic group; and each of La and Lb independently is a group which does not form a conjugated system in combination with the conjugated system of each of Ea and Eb and at least one of which has a site imparting water solubility to the compound or a site that is convertible into a site imparting water solubility to the compound, is favorably employable as an electroconductive threading intercalator in an electrochemical method for detecting complementary DNA fragments.
摘要:
An information processing apparatus capable of communicating with machines configured to operate in a first operation mode and in a second operation mode in which energy consumption is lower than the first operation mode via a network is provided. The information processing apparatus includes a processor configured to obtain from the machines data sets including a use time information item generated when the machines are used; and generate time information used for transitioning from the first operation mode to the second operation mode by calculating differences between the use time information items of the data sets for each of the machines.
摘要:
Disclosed is a composition containing zinc ester functional polymer and particulate copper pyrithione, wherein the particles have an average aspect ratio within a range of from about 8 to about 15, where the zinc ester functional polymer and the copper pyrithione are obtained by reacting an acid functional polymer with zinc pyrithione and a copper salt or a copper carboxylate. Also disclosed is an antifouling coating containing such a composition.
