Title: Method for charging ore into smelting reduction furnace
Inventor: SUZUKI SATORU
IPC: C21B11/00
Filed: 1988-03-26
Abstract: PURPOSE:To enable charging of fine granular ore into upper part in a smelting reduction furnace and to easily shift the ore into metal bath by hot-forming the fine granular ore into the specific grain size of granule without using binder after suitably pre-reducing the fine granular ore and agglomerating. CONSTITUTION:The fine granular ore having <=2mm grain size is pre-reduced to come to >=40% metallic iron (M.Fe). This reduced ore powder is hot-formed into granule having >=5mm grain size. This reduced ore powder develops metal- bond between mutually grains and firmly agglomerates without needing any binder. By charging this agglomerated ore into the smelting reduction furnace from upper part, the upper charging of the above fine granular ore can be executed and the charged fine ore is easily shifted into the metal bath and the yield is improved.

Title: Method for evaluating jitter in image input device
Inventor: OMURA KATSUYUKI
IPC: G03G15/04
Filed: 1991-03-13
Abstract: PURPOSE:To independently and quantitatively detect jitter on each point by inputting a reference gratinglike image, dividing the inputted image in the spatial frequency distributing direction of the reference grating by regarding one period of the reference grating as one section, integrating respective sections, and calculating the phase shear of the reference grating in each section. CONSTITUTION:A target device to be evaluated inputs the reference grating-like image 2 consisting of a sine wave or a rectangular wave having a single frequency band, and while scanning the image 2 in the main scanning direction (x), moves a scanner 1 in the sub-scanning direction (y). The target device is arranged so that the reference grating intersects with the main scanning direction (x) at right angles to read out the input image. When the scanner jitter of the target device includes an x direction component, the phase of the reference grating on the input image is distorted on jitter generating positions A, B, so that the phase shear of the reference grating can be detected. Thus the amplitude of the jitter is calculated based upon the phase shear and the spatial distribution of the scanner jitter in the image call be independently and quantitatively detected on respective points.
