Title: Image forming device and its control method
Inventor: ASAI HIDEHIKO
IPC: H04N1/04
Filed: 1997-12-02
Abstract: PROBLEM TO BE SOLVED: To form a satisfactory output image by detecting density distribution of stored image data, detecting positional deviation from a prescribed reference point and adjusting an output timing of image data to a printing means. SOLUTION: When it is decided as an input from a CCD, a reader part 1 reads an original for adjustment which is placed on an original platen and its image data selector 118 stores it in image memory 120. Positional deviation from a reference point in a horizontal scanning direction is measured. Density distribution of each line is acquired, and similarly, density distribution of a vertical scanning direction is also acquired. Next, each line of the horizontal and vertical scanning lines and density distribution information of a string are analyzed, and the positional deviation from the reference point is calculated. A position where density range from 0 to 255 is detected at the beginning of the string from every line and linear approximation is performed on it.  An intersection that is acquired from two linear approximations is decided as a position in an upper left corner of an original image, and an output timing of image data to a printing means is adjusted.

Title: Production of carbon fiber reinforced composite material
Inventor: YAMAMOTO IWAO
IPC: C04B35/80
Filed: 1996-12-12
Abstract: PROBLEM TO BE SOLVED: To easily obtain a thick formed body having a high fiber content and little irregularity of quality in a short time by two-dimensionally randomly orienting carbon short fibers and impregnating the fibers with a resin to obtain sheets, laminating these sheets, pressing in the lamination direction, and heating to remove the excess resin. SOLUTION: Carbon short fibers or precursor fibers are twodimensionally randomly oriented to obtain sheets, which are then dipped in a liquid resin diluted with a solvent, and dried to remove the solvent. The amt. of the resin added is controlled to obtain 20 to 60% carbon fiber volume Vf after formed. These sheets are laminated and held between two release paper sheets or metal plates of a same material and thickness on the upper and lower sides, and in this state, the laminated body is set in a hot press. The laminated sheets are subjected to primary pressing and compressed under about low pressure as 1/10 to 1/2 of the pressure of secondary pressing to obtain the thickness 2 or 3 times as much as the objective thickness. Then the sheets is preheated, heated to 60 to 500 deg.C, subjected to secondary pressing, and calcined to obtain a carbon fiber reinforced carbon composite material.

Title: Removing method and device for scale from steel pipe inner surface
Inventor: HIRATA GAKUO
IPC: B24C3/16
Filed: 1999-11-24
Abstract: PROBLEM TO BE SOLVED: To remove scale in a short time without being affected by irregularities of a ground metal in the steel pipe inner surface. SOLUTION: When a swirl flow of polishing materials is made to collide with the steel pipe inner surface to perform blast treatment, the pipe inner surface circumferential direction of the swirl flow is reversed. In this case, the pipe inner surface circumferential direction of the swirl flow is intermittently reversed, the swirl flow is directly generated on the polishing materials, and simultaneously, a steel pipe is rotated in the opposite direction to the swirl flow of the polishing materials. Therefore, the influence of irregularities of a metal ground in the steel pipe inner surface can be effectively prevented in removing scale, and the process time can be shortened.  The descaling efficiency is improved and the treatment time can be shortened by directly generating the swirl flow on the polishing materials, and simultaneously, rotating the steel pipe in the opposite direction to the swirl flow of the polishing materials.
