Title: Device and method for processing information, device and method for display and recording medium
Inventor: KUBONO HIDEO
IPC: G06T7/00
Filed: 1999-08-11
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of trouble caused by dispersion in the density of points in the original sequence of points by making uniform the density in the sequence of points and generating a curve for smoothing and approximating the sequence of points on the basis of the position information of respective points with the uniform density. SOLUTION: Respective measuring points are sorted along with a spatial stream (SP2). Concerning the provided sequence of measuring points, the spatial density of measuring points is made uniform (SP3). Concerning each measuring point in the provided sequence of measuring points, the value of weight corresponding to the position is respectively calculated (SP4). On the basis of the position data of these respective measuring points and the value of a weight constant or the like, a parametric natural spline function for smoothing and approximating the sequence of measuring points is calculated (SP5). Thus, since the spatial density is made uniform, the occurrence of trouble such as the eccentricity of measuring points to the spot of high spatial density, for example, caused by the dispersion in the spatial density of measuring points on the generated smoothed curve can be prevented.

Filed: 1998-08-14
Abstract: PROBLEM TO BE SOLVED: To improve a cast casting piece and enhance an yielding by contacting a molten steel fusion type gas to an injecting molten steel so as to restrain vibration of an immersion nozzle. SOLUTION: When a gas is taken into an immersion nozzle, a molten steel fusion type gas such as a nitrogen gas is supplied within a bulkhead by operating a switch valve of an Ar gas supplying pipe at a bulkhead part at which a sliding plate and the immersion nozzle are connected. The gas is sucked through the connecting part of the sliding plate and the immersion nozzle for penetrating into the molten steel while contacting with the injection molten steel so as to prevent a gas composed of other elements from being sucked into the immersion nozzle. Thus, formation of an air gap part in the immersion nozzle does not occur and, an inside of the immersion nozzle can be maintained at high negative pressure level, resulting in fulfilling with the injecting molten steel from a tundish and, the casting can be carried out while this condition is maintained.  Then, residue of an inclusion due to a powder contamination can be prevented by avoiding a discharge of the gas into the molten steel from a discharge opening of the immersion nozzle.
