Title: Surface reforming of fiber-reinforced formed body
Inventor: MIYAHARA KAORU
IPC: C01B13/18
Filed: 1997-09-09
Abstract: PROBLEM TO BE SOLVED: To uniformly coat the surface of fibers with a metal oxide to carry out surface treatment with excellent homogeneity by immersing a reinforcing fiber formed body in a soln. where metal hydroxide is produced by slow chemical reaction, precipitating the metal hydroxide on the fiber surface, and then calcining the body to convert the metal hydroxide into metal oxide. SOLUTION: The chemical reaction to produce a metal hydroxide is performed by heating a soln. containing a metal salt and urea to hydrolyze the urea to produce ammonia, which converts the metal salt into metal hydroxide, or by adding water to a soln. prepared by dissolving metal alkoxide in solvent and slowly hydrolyzing the metal alkoxide to change into metal hydroxide. The reinforcing fiber 1a which constitutes the fiber formed body 1 consists of continuous fibers of carbon, silicon carbide, silicon nitride or alumina. The fiber formed body 1 is immersed in a reaction liquid 2 in which a metal salt and urea are dissolved, and the soln. is heated to precipitate a metal hydroxide 3 on the fiber surface. The body is cleaned and dried to remove the reaction liquid 2. Then the body is calcined to obtain a reinforced fiber formed body 5 coated with a metal oxide layer 4.

Filed: 1984-11-19
Abstract: PURPOSE:To detect accurately the tilt angle of paper currency on a conveyance path to its conveyance direction by detecting the position shift in the direction crossing the conveyance direction at right angles at two points on one side of the paper currency facing in the conveyance direction. CONSTITUTION:When photosensor groups of photosensor arrays SB and SD turn on, it is judged that the paper currency arrives on sensors. Then when it is judged that the paper currency is positioned on the photosensor arrays while the two sides of DE and FG facing in the conveyance direction cross measurement lines AC and BD, the position shift l2 in the measurement line direction is calculated at two points A and B. Then, apparent length l3 is found. The tilt angle theta is calculated from the orthogonal relation between (direction of measurement line) and (conveyance direction) and the actual length l of the paper currency is calculated from the tilt angle theta. Then, a decision on the paper currency length is made by using the length l and it is judged whether the length l satisfies an expression or not; when so, it is considered that the kind of the paper currency is normal and the conveyance of the paper currency is carried on. When not, it is considered that the kind of the paper currency is different and the paper currency is collected.
