Title: Method for selectively recovering copper
Inventor: OTO SHUICHI
IPC: C25C1/12
Filed: 1987-05-06
Abstract: PURPOSE:To recover Cu having a low impurity content by electrodeposition on the cathode by heating a Cu-contg. soln. contg. As, Sb, Bi, etc., as impurities in an electrolytic cell to a specified temp. and by electrolyzing the soln. under stirring. CONSTITUTION:An aq. soln. contg. 0.5-20g/l Cu ions, 2-20g/l As ions, 0.05-0.50g/l Sb ions, 0.05-0.50g/l Si ions and 200-500g/l sulfuric acid is heated to 40-80 deg.C, poured into an electrolytic cell and electrolyzed at 100-350A/m<2> current density under mechanical stirring. Since the lowering of the concn. of Cu ions in the electrolytic soln. in the vicinity of the surface of the cathode is prevented by stirring the electrolytic soln., Cu is selectively electrodeposited on the cathode from the electrolytic soln. without depositing As, Bi or Sb.

Title: Method for purging in regenerative-type gas-heating oven of vertical-type briquette coke carbonization oven
Inventor: TAWARA YOUICHI
IPC: C10B21/10
Filed: 1980-08-08
Abstract: PURPOSE: To prevent the lowering of the qualities of coke caused by the intrusion of purging gas from the regenerator into the carbonization oven in the course of heating a part of the exhaust gas of the carbonization oven in the regenerator and recycling the gas to the carbonization oven, by extracting the purging gas from the gas recycling system, and exhausting to the outer atmosphere after the heat recovery.  
     CONSTITUTION: Briquette coal 1 is charged in a vertical-type continuous carbonization oven 5, a part of the generated gas discharged from the top of the charbonization oven 5 is heated and supplied to the carbonization oven 5 as recycling gas, and the carbonization of coal is carried out to obtain coke. In the above process, hot gas prepared by the combustion of the fuel 14 with air 15 in the regenerative-type heating oven 16 is used for the heating of the regenerators 17 and 25, and purged with purging gas 33, such as steam. The recycling gas is heated in the regenerator, supplied to the carbonization oven, purged with the purging gas, and the regenerator is heated with the hot gas; and the above steps are repeated. In the above process, the gas exhausted from the regenerator is heat-recovered with a separate heat-recovering apparatus installed outside of the gas recycling system and exhausted from the system until the purging gas is completely discharged.

Title: Generation of nmr spectrum of desired of object
Inventor: ROJIYAA JIEI OODEITSUJI
IPC: A61B5/055
Filed: 1989-04-27
Abstract: PURPOSE: To expand the ISIS technology to select a large number of material volumes and save time for experiments among the number, size, and position of the selected cubes by adding/subtracting and combining together M pieces of NMR response of subjects including the data from a plural number of smaller volumes. CONSTITUTION: Figure (A) shows an irregular volume (in a solid line) divided into 7×5 matrixes of cubes. In order to prevent detection of signals from volumes out of the area concerned, only the signals from the shaded cubes shown in the figure (A) are effective in an NMR experiment restricted in space. Figure (B) shows that the same space distribution of effective signals can be measured in the ISIS experiment consisting of 4×4 rectangular elements of various sizes. The corresponding decrease in the number of the ISIS volume elements minimizes the ISIS experiment necessary to investigate sample volumes. A general rule to reconstruct a spectrum using addition/subtraction of signals with single inversion and double inversion will be extended to a 2<p> ×2<q> dimensional matrix at the maximum with p and q being integral numbers.

Abstract: PURPOSE:To easily remove a bubble in a head, by a method wherein, when the bubble in the head is detected, the bubble is expelled by replacing ink in the head with a solvent, and the solvent is then replaced with ink. CONSTITUTION:When a bubble detector 14 (for example, which detects a change in a motional impedance in an ink liquid chamber by observing it through an electric distortion vibrator 2) detects a bubble 7 existing at the inside of an ink-on- demand type ink jet head 10, the ink in the head 10 is pulled back to a switch valve 13 with a control circuit 15 actuated. An ink feed path of the switch valve 13 is closed off, and a solvent feed path is opened, whereby the solvent is supplied from a solvent feeder 11 to fill the head 10 with the solvent. After the switch 13 is changed over to an ink feeder (12) side and injection of the solvent in the head is then completed, the head is restored to a normal condition.

Title: Automatic focus adjusting device
Inventor: HAMADA MASATAKA
IPC: G03B13/36
Filed: 1987-05-01
Abstract: PURPOSE:To reduce the missing of a shutter chance by allowing shutter release when a focused state can be almost attained at the time of practical exposure even if the focused state is not set up yet at the time of shutter releasing operation. CONSTITUTION:When an shutter releasing operation means is operated, the shutter releasing operation is detected by a releasing operation detecting means and a defocused value at that time is calculated by the 2nd defocused value calculating means. When the defocused value calculated by the 2nd defocused value calculating means is a prescribed value, the shutter releasing operation is inhibited, but when the value is the prescribed value, the lens can be driven up to almost the focusing position until the start of exposure. Thereby, the start of the shutter releasing operation is permitted by a release permitting means and the lens is driven by an operation control means on the basis of the detected defocused value during the release time lag up to the start of the exposure.

Abstract: PURPOSE: To produce powder for a catalyst having high catalytic activity at a low cost by heating the solution of the complex of both of nitrates of metallic elements constituting powder for a CuCr-based oxide catalyst with an amino acid at the temperature not lower than the boiling point of the solution. CONSTITUTION: In the case of producing powder for a CuCr-based oxide catalyst used as a catalyst for hydrogenation and dehydrogenation, the solution of the complex of both of nitrates of metallic elements constituting this powder with an amino acid is heated at the temperature not lower than the boiling point of the solution. Since respective metallic elements are mixed in the solution state of the complex of amino acid, uniform mixing is enabled in an atom level. Furthermore, when the solution is heated and dried to remove the solvent of the solution, residue causes self-combustion and powder having a spinel structure is produced by heat of combustion. Such powder is obtained as particle diameter is very minute and particle size distribution is in narrow range and composition is uniform because this combustion is finished in narrow space and a narrow temperature range at short time.
