摘要： An object of this invention is to provide a fine powder of diamond particles of less than 50 nm with a narrow particle size range. The diamond is single crystalline and characterized with a lot of sharp edges and sharp points. Another object is to provide a method for efficiently producing such fine powder.The method comprises mechanically crushing a raw material of single crystalline diamond particles to prepare starting minute particles of diamond, then imparting hydrophilic quality to the surface of diamond particles. As hydrophilic the diamond particles are dispersed in water to form a slurry, which is set and kept weakly alkaline. The slurry is then subjected to a preliminary grading step, whereby the slurry is removed of a top particle size fraction of the diamond particles that has a D50 size of 60 nm or more. Eliminated of said top particle size fraction, the slurry is then diluted with water to regulate the diamond concentration to 0.1% (by weight) or less. The slurry so conditioned is subjected to a centrifugal force, whereby a coarser particle size fraction of the diamond particles is condensed to a solid cake and removed from the slurry. Effluent slurry is taken out from the centrifugal grading that contains a fraction of the diamond particles having decreased particle sizes.

摘要： A color image processing apparatus realizes color reproduction in a color image output apparatus by controlling the total amount of coloring material used while making full use of the color reproduction range of the color image output apparatus. To this end, a signal C′M′Y′K′, obtained after a &ggr; conversion (gamma conversion), is converted into an amount of ink drops V (CMYK) at a conversion unit. Then, at a total ink drop quantity control unit, a total ink quantity of the amount of ink drops converted at the conversion unit and a limit value (maximum total ink drop quantity) stored in a maximum total ink quantity memory unit are compared, and the total ink quantity is controlled to be lower than the limit value. Then, the controlled amount of ink drops is converted into a recording control signal C″M″Y″K″ at a control signal conversion unit.

摘要： A color matching process which can respond to a type of object to be processed is automatically performed by a printer driver. The color conversion method converts first color image information into second color image information output to a color image outputting apparatus. It is determined whether or not the first color image information includes an instruction for designating a color matching method. A type of each object included in the first color image information is discriminated when the first color image information does not include the instruction for designating a color matching method. One of a plurality of color matching methods suitable for the type of each object is selected in accordance with previously prepared correspondence information between each type of object and each color matching method. A color matching process is performed on each object in the first color image information by using the selected color matching method so as to convert the first color image information into the second color image information.

摘要： A converting unit converts a first color signal into a second color signal and a third color signal. A first correcting unit corrects a magnitude relation between hue angles of the third color signal such that a magnitude relation between hue angles of the second color signal corresponding to the first color signal is maintained in the hue angles of the third color signal. The first color signal is a device-dependent input red, green, blue color signal. The second color signal is a color signal of a hue, lightness, saturation color space. The third color signal is a color signal of CIECAM02 color space.
