摘要:
The present invention relates to a carbon fiber bundle to which an amino group-containing modified polyolefin resin has applied, wherein the amount of applying amino group-containing modified polyolefin resin is 0.2 to 5.0% by mass. This carbon fiber bundle can be produced by applying 0.2 to 5.0% by mass of the amino group-containing modified polyolefin resin to the surface of the carbon fiber bundle. The present invention can exhibit excellent interface adhesion to a polyolefin resin, particularly to a polypropylene resin, and can provide a carbon fiber bundle useful for reinforcing the polyolefin resin and a method of producing the same.

Included are determining a position of a pixel serving as an extraction subject by using first image data photographed under a first light source; determining an extraction range corresponding to the determined position, by using a color value of the pixel at the determined position and a color value of a pixel at a peripheral position around the determined position in the first image data; calculating a first representative color value from the first image data and a second representative color value from second image data photographed under a second light source, on the basis of the position of the pixel serving as the extraction subject and the extraction range; and generating a color correction condition for converting a color value depending on the first light source into a color value depending on the second light source.
摘要:
A method for manufacturing polycrystalline silicon with high quality by effectively preventing undesired shape such as giving an rough surface to silicon rods or an irregularity in diameter of the silicon rods. The method for manufacturing polycrystalline silicon includes: an initial stabilizing step of deposition wherein a velocity of ejecting the raw material gas from the gas ejection ports is gradually increased; the shaping step wherein first the ejection velocity is increased at a rate higher than that in the stabilizing step and then the ejection velocity is gradually increased at a rate lower than the previous increasing rate; and a growing step wherein, after the shaping step, the ejection velocity is made slower than that at the end of the shaping step until the end of the deposition.
