Title: Method for recovering ruthenium
Inventor: TAKAO HIROSHI
IPC: C22B11/00
Filed: 1989-03-28
Abstract: PURPOSE:To easily execute recovery of ruthenium at high yield by absorbing quartvalent ruthenium ion dissolved in hydrochloric acid, etc., into anion exchange resin and recovering. CONSTITUTION:The quartvalent ruthenium ion dissolved in the hydrochloric acid or aqua regia is adsorbed into the anion exchange resin and recovered. Then, the anion exchange resin is not limited to the particular condition, but it is desirable to use the fine granular material and the quantity, of which number of site in the exchange resin is at least 2-3 times of number of the ruthenium ion. Further, in the case the ruthenium ion is trivalent, by oxidizing this ion to the quartvalent with oxidant (sodium hypochlorite, etc.), the recovering ratio is improved and further, by executing heating treatment to the ruthenium ion with the hydrochloric acid, etc., to exchange this into chlorocomplex, the ruthenium can be quantitatively recovered. By this method, the ruthenium dissolved in the waste solution can be selectively recovered.

IPC: F28F13/02
Filed: 1982-05-06
Abstract: PURPOSE:To obtain the heat transmission surface with a large number of cavities of aimed shape by alternately executing etching and corrosion-resisting plating repeatedly to spherical graphite cast iron. CONSTITUTION:When etching spherical graphite cast iron, a section in the vicinity of the surface of cast iron is changed into a porous body consisting of the hemispherical cavities. When a sample surface just after etching is electroplated thinly with a metal having excellent corrosion resistance such as chromium and the porous body is etched again, the cavities, in which graphite particles remain, and the cavities of small opening-section diameters are corroded selectively because of incomplete internal plating though the flat section of the surface with a sufficient corrosion-resisting plating layer is hardly corroded, remaining graphite particles fall in an etching fluid, and the internal diameters of the cavities of the small opening-section diameters increase.

Abstract: PURPOSE:To attain high data compression by detecting complexity of a picture so as to reduce the quantity of picture codes of block picture data with high picture complexity. CONSTITUTION:A dividing means 10 divides picture data into blocks. A transformation means 11 applies orthogonal transformation to the block picture data divided by the means 10 to calculate a transformation coefficient for each frequency component. A quantization means 13 uses a quantization threshold level set in the common mode to the entire picture data to quantize the transformation coefficient calculated by the means 11 thereby calculating the quantization transformation coefficient. A coding means 15 applies variable length coding to the quantization transformation coefficient to generate a picture code. Then a detection means 17 detects complexity of the picture represented by the block picture data divided by the means 10, and a reduction means 16 reduces picture codes of the block picture data with high picture complexity to be detected. Thus, the code is decoded by a standard algorithm and high data compression is attained.
