摘要:
An appropriate binarization threshold can be automatically set between the object density and the background density in a multi-level input image, by determining the frequencies of the luminance levels of the entire image, then calculating the average and deviation of the frequencies, then specifying a region containing the optimum threshold for separating the object and the background in the image, by judging the magnitude of the deviation, and taking the average luminance of the specified region as the binarization threshold. Also in processing an image containing objects of three or more luminance levels, highly precise binarization according to the luminance hierarchy allows exact separation of the image regions, enabling precise character recognition process according to the hierarchic luminance levels.

An image processing apparatus prevents an increase in random noise and the like produced by distributing a transformation error, which is produced at the time of a level-number transformation, to unprocessed pixel data. Error data X.sub.n is added to pixel data, which has entered via an input unit, by an adder. Thereafter, the resulting data is subjected to a level-number transformation by a binarizing circuit. Transformation error produced at the time of the level-number transformation is calculated by an error arithmetic unit. The transformation error thus calculated is distributed to unprocessed pixel data by an error-diffusion unit, and the error is accumulated in a line buffer memory as error data. When processing of a prescribed number of lines has ended, a line-number discriminating circuit clears the error data that has been accumulated in the line buffer memory. As a result, an increase in random noise is prevented.

The present invention relates to new aqueous microemulsions containing organic pesticide compounds of limited water-solubility and to their use for plant protection, including seed and crop protection, and protection or non-living material. The aqueous microemulsions comprise a) at least one pyrethroid compound P; b) at least one organic solvent, selected from compounds of the formula I R1—(O-Alk)m-O—C(O)R2 (I) wherein m is 1, 2 or 3, R1 is H, C1-C6-alkyl or C(O)R3, R2 is hydrogen or C1-C4-alkyl, which may be unsubstituted or substituted with OH, Alk is C2-C6-alkylene, and R3 is hydrogen or C1-C4-alkyl, which may be unsubstituted or substituted with OH; c) at least one surfactant; and d) water.

A stage comprises a linear guide rail (2) for guiding a movable table (4), a driven bar (12), a linear drive actuator in contact with the driven bar (12) to transmit driving force to the driven bar (12), and parallel plate springs (30) for holding opposite ends of the driven bar (12). A drive transmitting surface of the linear drive actuator is provided so as to be separated from the movable table (4), and this prevents the accuracy of positioning from being reduced. Also, the parallel springs (30) reduce deforming forces applied to sections supporting the driven bar (12), and this prevents the driven bar from being damaged. The configuration makes the stage highly accurate and highly reliable.

A method for producing a high-quality group-III element nitride crystal at a high crystal growth rate, and a group-III element nitride crystal are provided. The method includes the steps of placing a group-III element, an alkali metal, and a seed crystal of group-III element nitride in a crystal growth vessel, pressurizing and heating the crystal growth vessel in an atmosphere of nitrogen-containing gas, and causing the group-III element and nitrogen to react with each other in a melt of the group-III element, the alkali metal and the nitrogen so that a group-III element nitride crystal is grown using the seed crystal as a nucleus. A hydrocarbon having a boiling point higher than the melting point of the alkali metal is added before the pressurization and heating of the crystal growth vessel.

In a second horizontal plate (18a) bottoming an atmosphere recovery box (18), there are formed circular holes (21) between blowout pipes (20) adjacent to each other. Each of partition walls (2) positioned above a conveyor (5) includes an upper portion formed from a heat-insulating wall (2a) including a heat-insulative material having a thickness of T, and a lower portion formed from a metallic-plate wall (2b) extending downward from the heat-insulating wall (2a) toward the conveyor (5). The pitch P2 of the blowout pipes (20) across the metallic-plate wall (2b) is substantially same as the pitch P1 (12 mm) of the blowout pipes (20) disposed inside each of the chambers (R1 to R5) and adjacent to each other.
