A position detection apparatus detecting a position of a mark similar to a template image from an input image has a calculation block. The calculation block includes phase difference calculation means and mark position detection means. The phase difference calculation means calculates a phase difference between a phase component of each frequency component when the template image is transformed into frequency components and a phase component for each frequency component when an input image is transformed into frequency components with a reference point being set at a predetermined position on the input image. The phase component difference calculated by the phase difference calculation means is transformed into a phase impulse response function, according to which the mark position detection means detects the position of the mark on the input image.

An image processing apparatus for detecting the inclination of an object is provided. This image processing apparatus has a read means which reads the object and outputs image data, an amount of change calculation means which calculates the sum of the amounts of change of the image data of the object in at least one direction, and an inclination calculation means which calculates the inclination of the object based on the sum calculated by the amount of change calculation means.
摘要:
A method of producing β-SiAlON includes a sintering process, in which β-SiAlON starting materials, a mixture of silicon nitride, aluminum nitride, optically active element compound, and at least one compound selected from aluminum oxide and silicon oxide, are sintered at temperatures ranging from 1820° C. to 2200° C. The method provides new β-SiAlON low in carbon content and having high luminescence intensity by placing a plurality of boron nitride vessels in a graphite box to allow the β-SiAlON starting materials packed in the plurality of boron nitride vessels to easily come in contact with nitrogen gas, and performing sintering in nitrogen atmosphere.

Provided is a production method of a β-type sialon fluorescent substance, where luminescence intensity can be improved without adding a metal element other than elements composing a β-type sialon fluorescent substance. Namely, in a production method of a fluorescent substance containing an optically-active element as the luminescence center in a crystal of nitride or acid nitride, a β-type sialon fluorescent substance is produced by a burning process for heat-treating a mixture including metal compound powder and an optically-active element compound; a high-temperature annealing process for heat-treating the burned product after cooling under a nitrogen atmosphere; a rare-gas annealing process for heat-treating the high-temperature annealed product under a rare gas atmosphere; and a process for treating the rare-gas treated product with an acid.
