Title: Device for collecting liquid carbon dioxide
Inventor: OSHIMA KAZUAKI
IPC: C01B32/50
Filed: 1991-06-05
Abstract: PURPOSE:To obtain a low power consumption type device by compressing and cooling a carbon dioxide concentrated gas adsorbed by a PSA carbon dioxide concentrator which concentrates carbon dioxide in dehumidified gas and liquefying roughly the gas by way of a Joule-Thomson valve and then producing a highly concentrated liquid in a refining tower. CONSTITUTION:The combustion gas of an LNG combustion boiler of a power plant is introduced into a PSA dehumidification device 2 filled with a moisture adsorption material. After the moisture is eliminated, the combustion gas is introduced into a PSA carbon dioxide concentrator 3 in which carbon dioxide adsorption material is filled so as to adsorb about 90% of carbon dioxide selectively. The dry gas containing residual carbon dioxide is introduced into a PSA dehumidification device in a reproduction process so as to regenerate the moisture adsorption material. The carbon dioxide adsorbed in the concentrator 3 is pressure-reduced and collected by means of a vacuum pump 5. After it is once stored in a surge tank 6, the carbon dioxide is boosted by a compressor 8 and roughly liquefied by way of a heat exchanger 9, a Joule-Thomson valve 10 and then it is collected as a highly concentrated liquefied carbon dioxide at a refining tower 11 whereas a non-concentrated gas is circulated to the concentrator 3.

Title: Picture processing unit and method therefor
Inventor: HASE MASAHIRO
IPC: G06T1/00
Filed: 1995-05-31
Abstract: PURPOSE: To obtain the same output picture by any picture input device. CONSTITUTION: A gray scale picture of a prescribed density pattern is read in from a scanner A. When calibration is indicated, a profile generation part 12 obtains the gamma characteristic of the scanner A from this signal and stores it in a memory 14. A prescribed color patch is read in also, and tristimulus values are obtained based on it and are stored in the memory 14. Since a picture is corrected based on the characteristic stored in the memory 14 ana is outputted at the time of normal picture reading-in, the same output is obtained for the same original picture regardless of the change of the characteristic of the scanner or the change of the input device.

Title: Method and device for adjusting guide-in pressure of fluid body, and method and device for guiding fluid body in
Inventor: YOSHIE YASUTETSU
IPC: G02B6/44
Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To easily adjust pressure according to variation in overflow amount without providing any complicated controller on a pressure source side by providing a branch pipe which communicates with a guide-in pipe, making part of a pressure-fed fluid body overflow to the branch pipe, and controlling the pressure of the fluid body supplied to a tubular body. SOLUTION: The guide-in pipe 3 is arranged intruding into the tubular body 1 from its opening part. The branch pipe 4 is connected to the guide-in pipe 4 nearby its entrance side 3B, and this branch pipe 4 is fitted with a manometer 5 and an adjusting means 6 for a valve, etc. When the fluid body is pressurized and fed to the guide-in pipe 3, the pressure of the fluid body operates on the branch pipe 4 and is always measured by the manometer 5. When it is decided that the pressure is higher than a specific value, the adjusting means 6 is properly opened to discharge part of the fluid body, thereby properly correcting the pressure in the guide-in pipe 3. Therefore, the guide-in pressure of the fluid body charged in the internal space 2 can be adjusted only by the adjusting means 6 without controlling the pressure on the supply device side.

Title: Treatment of molten fly ash
Inventor: MIIKE KAZUHIRO
IPC: B01D53/77
Filed: 1998-05-18
Abstract: PROBLEM TO BE SOLVED: To efficiently and economically treat molten fly ash by utilizing an existing copper refining equipment by subjecting molten fly ash to exudation treatment by using the gas scrubbing water discharged from an exhaust gas desulfurization treatment system and using the exuded residue as a lead refining raw material. SOLUTION: The concn. of sufuric acid in the gas scrubbing water desulfurization plant of copper refining is about 100-150 g/l and this gas scrubbing water is utilized as a sulfuric acid exudation soln. of molten fly ash. If the molten fly ash is subjected to exudation treatment by the gas scrubbing water containing sulfuric acid, zinc is exuded to be transferred to the exudation soln. (gas scrubbing water) but lead is not exuded to remain as exudation residue and, therefore, lead is filtered off to be recovered and the exudation residue containing lead is utilized as a lead refining raw material. By this constitution, molten fly ash can be efficiently and economically treated by utilizing an existing equipment.

Abstract: PURPOSE: To prevent the damage of a fixed contact and a moving contact by causing the end portion of a moving contact to follow the fixed contact without loosing contact with the fixed contact when the fixed contact starts vibration. CONSTITUTION: When an electromagnetic device 1 is excited, a control solenoid 10 moves a moving core 15 toward a moving assembly 17. The core 15 reaches the rod 18 of the assembly, and energizes the same to a fixed contact 5a. After the moving core 15 brings a moving contact 22 into contact with the contact 5a, the same continues movement toward an engaging member 8. In response to it, the rod 18 impulses against the moving contact 22 abutting the fixed contact 5a, and advances toward the bottom portion wall of a support member as compressing a coil spring 24 between the moving contact 22 and a bush 21.  The acceleration of the free end 40 of the moving contact 22 in a vibration mode is caused to be larger than the acceleration of the fixed contact 5a, and the amplitude of vibration is caused to be larger than the amplitude of the fixed contact 5a so that the contact of both contacts can be maintained.
