IPC: C01G23/00
Filed: 1984-06-01
Abstract: PURPOSE:Titanium slag which is formed in the production of pig iron from ilmenite is used to utilize an impurity included therein whereby the titled fiber, which has high heat resistance and cation-exchanging ability, is produced. CONSTITUTION:Titanium slag and rutile or anatase sand are mixed in such a proportion as the former is less than 3/1 in weight. When the mixture is represented by formula I (M is metal as an impurity included), it is combined with potassium oxide or a compound which can form the same by heating (when needed, a mixture of both) so that formula II is satisfied. The resulting mixture is melted to form a fibrous material of crystals having the same layer structure as that of formula III, then, the product is treated with an acid to extract out the all potassium components, then substituted with hydrogen ions. Thus, fibers are obtained, which will be used as a barrier in treatment of radioactive waste and in collection of uranium from sea water, because it has cation-exchanging ability.

IPC: H04N9/75
Filed: 1989-05-08
Abstract: PURPOSE:To convert a partial area of a color picture onto a desirable color in a short time by transplanting only the chromatically information and no luminance information when a picture is corrected. CONSTITUTION:The original picture signals are read out of memories 1-3 for original pictures and displayed at a picture display part 8. An operator designates the area of an appropriate object that covers a highlight part via a coordinate point input part 9 by reference to the part 8. Then the operator segments an area designated by a picture processing part 7 and designates an embedding position of the picture segmented by the part 9 by reference to the part 8. When the segmented picture is embedded for synthesization, only the I and Q signals equivalent to the chromatically information are synthesized together. While the Y signal equivalent to the luminance information is not synthesized and an original picture is kept as it is. That is, the signal read out of the memory 1 is written into a memory 4 as it is. The I and Q signals read out of memories 2 and 3 are written into memories 5 and 6 respectively at the designated embedding positions.
