Abstract: An image forming apparatus outputs a proof chart in response to an instruction for calibration execution from a user and then a color measuring unit measures the colors of patches on the proof chart. A profile management unit selects, from entries in a base profile DB, a base profile in an entry that has color reproduction characteristics that are closest to the color measurement values of the patches and generates a sheet correction TRC that has an approximation to the color measurement values of the patches when the selected base profile is used. The selected base profile is used as a color conversion parameter in a color management module, and the generated sheet correction TRC is used as a tone correction parameter in a sheet-corresponding correcting unit.

Abstract: An electrophotography apparatus prevents the edge effect without causing the blurring or loss of a single-dot image or a single-dot-width line. Based on a measurement of a testing patch, two templates with different sizes are generated. Image data to be printed is subjected to template matching using the templates to obtain a difference region as an image edge region of the image data where, when the image data is developed, the amount of attached toner is increased. The exposure amount for the image edge region is controlled based on a measurement of the amounts of attached toner in edge portions of the testing patch so that the difference in the attached toner amounts are minimized.

Abstract: Multiple piezoelectric elements 35 are arranged in a row along the top of liquid level in the reaction vessel 11. An ultrasonic reflecting material 38 is installed on the bottom of the portion of the heat insulating bath 12 where heat insulating medium 13 is stored. A lateral ultrasonic wave 9b is generated on the lower side is generated by actuation of the piezoelectric element 35. Wave 9b is reflected by the ultrasonic reflecting material 38. As a lower ultrasonic wave 8 advances along the wall surface of the reaction vessel, it collides with the specimen liquid level, thereby causing a portion of the liquid level closer to the piezoelectric element 35 to be raised. When the lateral ultrasonic wave 9a is applied to this portion, it reaches the inclined portion of the raised liquid level of the specimen. Swirling flow by agitation 36 is produced by the acoustic radiation pressure of the ultrasonic wave. The specimen and reagent are mixed and agitated by this swirling flow.

Abstract: A reagent dispensing mechanism (15), first and second dispensing-mechanism transfer means (26, 27), and a second reagent vessel (reagent cassette) carrying-in/out mechanism (24), which are constructed by employing an XY-mechanism, are arranged so as to travel above a reagent table (25) to carry in/out a reagent cassette (22). As compared with the case where the reagent cassette carrying-in/out mechanism (24) is installed radially of the reagent table (25), the area of an automatic analyzer in the horizontal direction can be reduced and a reagent vessel (16) can be moved to a predetermined position in a shorter time by combining the rotation of the reagent table (25) with the movement of the XY-mechanism. Further, as compared the case of dispensing reagents from reagent vessels in a matrix pattern by using the reagent dispensing/transferring mechanism, the travel distance of the transferring mechanism can be shortened and so can be the travel time.
