A laser interferometer (10) comprises: a first beam splitter (22) which splits a laser beam emitted from a light source (3) into a first beam (L2) and a second beam; a second beam splitter (24) which splits the second beam into a third beam (L1) and a fourth beam (L3), and which causes reflected beams, produced by reflection of the split beams (L1, L3) and incident from reverse directions to the directions of the split beams, to exit in a reverse direction to the direction of the second beam; and a beam selecting unit (50, 51, 60, 66, 68) which, from among the reflected beams produced by reflection of the third and fourth beams (L1, L3) and caused to exit the second beam splitter (24) in the reverse direction to the direction of the second beam, selects a beam to be combined in the first beam splitter (22) with a reflected beam produced by reflection of the first beam (L2) and incident on the first beam splitter from a reverse direction to the direction of the first beam (L2).

Coordinates in an image and its corresponding color-converted data are supplied to a control/operation portion for every pixel. Quantization is applied to each color. The quantization is carried out so that a kind of dot for at least one color is made different from kinds of dots for the others in one and the same pixel when dots for different colors are superimposed on the pixel. The control/operation portion refers to a two-dimensional matrix on the basis of the quantization result, determines an output dot for each color, and converts the data into data which can be processed by a printer. The printer records an image based on the quantization result while reciprocating a recording head. Thus, it is possible to reduce color shift caused by the difference of the ink landing order at the time of reciprocating the head for recording.

A method of dehydrating an organic sludge, which comprises adjusting the pH value of a sludge having a solids concentration in the range of from 0.5 to 8% by weight, to a pH of 5 or less, heating the thus adjusted sludge, mixing with the sludge an oxidizer capable of displaying oxidation ability within the acid region, and dewatering the sludge with a dehydrator.

On the basis of name of a printing medium, which is supplied from a printing medium specifying section, a recording pattern producing section determines whether the printing medium to be printed is a medium in which an ink easily penetrates or that in which an ink hardly penetrates, determines hue changing degree due to bidirectional printing for each pixel from position information of CMYK image data and a scanning pattern, and changes the densities of CMY so that the output density of a hue having a larger hue changing degree in the input image data is lowered, and that of a hue having a smaller hue changing degree is raised. As a result, a total amount of inks ejected from a head of an ink recording section is controlled with respect to the color which is early impacted and that which is lately impacted.

摘要:
A coloring material recording device comprises a plurality of image recording elements and a control unit. The plurality of image recording elements record with a plurality of coloring materials on a recording medium and form an image, and one of the plurality of image recording elements is provided for each of the coloring materials. The control unit controls the plurality of image recording elements such that detection images of at least two coloring materials of the plurality of coloring materials overlap each other on the recording medium.
摘要:
A publication information acquisition apparatus used by a user of a service converts information extracted from a newspaper into electronic information and transmits the electronic information to a publication information providing apparatus. The publication information providing apparatus decodes the electronic information, acquires key information for searching for characters and/or an image from the decoded electronic information, and searches newspaper information in a database based on the key information. The publication information providing apparatus acquires the name of a newspaper and the date of issue thereof as confirmation information and transmits the confirmation information to the publication information acquisition apparatus. It is therefore possible to easily know from which newspaper the extraction is acquired and when the newspaper was issued.
