Title: Production of urea
Inventor: FUJII HIDETSUGU
IPC: C07C239/00
Filed: 1984-11-02
Abstract: PURPOSE:To decrease the amount of unreacted component in the production of urea from carbon dioxide and excess ammonia by stripping process, by extracting the inert gas flowing into the process from the accumulated part, and using the gas as the stripping agent. CONSTITUTION:Ammonia is made to react with carbon dioxide at a molar ratio of 2.3-5.0 under a pressure of 140-200atm at 180-220 deg.C, and the obtained synthesis liquid is stripped with CO2 gas in the stripper 14 to separate the most part of the unreacted component as a gaseous mixture. The mixture is sent to the carbamate condenser 22, the unreacted component is absorbed in the aqueous solution of carbamate sent from the high-pressure scrubber 20 of inert gas, and the solution is returned to the synthetic reactor 12. The inert gas 60 subjected to the high-pressure scrubbing is introduced to the bottom of the medium-pressure decomposition column 16 and is used as a stripping agent. The amount of the unreacted component remaining in the synthetic liquid can be decreased compared with conventional process. The mixed gas discharged from the column 16 is sent to the medium-pressure absorber 24 to effect the absorption of NH3 and CO2, and the inert gas 64 containing NH3 and CO2 is used as the stripping agent in the low-pressure decomposition column 18.

IPC: F23G5/04
Filed: 1996-09-03
Abstract: PROBLEM TO BE SOLVED: To reduce a combustion cost of an incinerator by a method wherein after sewage dehydrated sludge is predried by heat discharged from a combustion furnace, the dried sludge is charged in the incinerator. SOLUTION: A part of steam (a) generated during drying of sludge is guided out from an exhaust part to the combustion chamber of a combustion furnace 11 and meanwhile, a remaining part of steam (a) is adhered to a collision chamber in a drying chamber 17 and recovered as water drips (b) and discharged from a drainage part to the outside of a chamber. In this way, sewage dehydrated sludge having a high moisture content enters a drying chamber 17 through the input port of a drying chamber 17 and thereafter, the sludge is conveyed to an output port by a sludge conveying device 18. During the conveyance, sludge is heated by hot blast blown out through a blow-out part from the incinerator 11 and drying is effected until a moisture content is reduced to a given value.  This constitution improves combustion efficiency, eminently reduces a combustion cost of the combustion furnace 11, and reduces consumption fuel, resulting in reduction of an amount of generating carbon dioxide by which atmospheric pollution occurring at the incinerator 11 is caused.

Title: Apparatus for collecting excessive mist in coating
Inventor: TAKEDA KOUJI
IPC: B01D45/08
Filed: 1983-12-10
Abstract: PURPOSE:To collect condensed mist with good efficiency without adhering the same to the interior of a dust collecting mechanism, by covering the mist condensed part in a mist condensing apparatus, wchin compresses and expands air containing sucked paint mist, with a water film. CONSTITUTION:When air containing excessive paint mist passes a mist condensing apparatus 4, compression, expansion and contact are repeated in said apparatus 4 and, therefore, paint mist having large mass is adhered to an impinged surface. At this time, because of a structure for allowing water sprinkled by a water sprinkling apparatus 5 to extend over total surfaces of a sucked air compressing mechanism, a sucked air contacting mechanism and a sucked air exhaust mechanism, paint mist being about to adhere is washed off by sprinkled water. Further, because water is sprinkled toward the direction of air, which is exhausted from the mist condensing apparatus 4, from the water sprinkling apparatus 5 above the mist condensing apparatus 4, paint mist slightly left in air, even if said air passes the mist condensing apparatus 4, can be perfectly removed in a state dissolved in water.

IPC: G11B27/10
Filed: 1986-10-01
Abstract: PURPOSE:To prevent contingency from being damaged by generating one of plural corresponding numerical values at random only when the number of detected information groups is larger than a prescribed value and inhibiting reproducing of the information group corresponding to the numerical value which is obtained when the current value of the obtained numerical value coincides with the preceding value. CONSTITUTION:If the number of pieces of music recorded on a disk is larger than a prescribed value, the execution of a routine executed just before is restarted. If it is detected that a play command due to an operation part 21 is issued during the execution of a main routine or the like and it is discriminated that a random play command is issued, a data output command is sent to a random number generating circuit 23 to take in output data of the circuit 23, and the music number of the music to be subjected to random play is determined. If the current value of the music number does not coincide with the preceding value, the current value of the music number is stored in the prescribed address of a RAM 26 as the preceding value. Next, the recording position of the music of the determined music number is searched. Only when the search operation is terminated, a subroutine to control the play operation is called. Thus, the contingency is not damaged.

Title: Method and device for welding tubular member composed of thermoplastic material
Inventor: PETERU KUNTSU
IPC: B29L23/00
Filed: 1988-09-20
Abstract: PURPOSE: To prevent inner circumferential beads from being formed and enable the strong welded connection by a method wherein the outer circumferences and the end surfaces of tubular components are heated by radiated heat and the end portions are butted together and the expandable support member is pressed to the inner wall of the end portion, being deformed and taken out to be returned to the original shape after the welding thereof is completed. CONSTITUTION: The end portions of tubular components 1a and 1b are heated non- contactwise with radiated heat 10 by a heater 4 from the outer circumferential surface and end surface until the melting range of the thermoplastic material is reached. The preheated outer circumferential support rings 5a and 5b are reciprocally approached until butted on the end portions thereof and clamp devices 3a and 3b are moved to the axis direction. This enables the end portions of tubular components 1a and 1b to be coupled under the specifically controlled conditions. Further, an inner circumference supporting device 6 is pressed against the inner walls 9a and 9b of the tubular components 1a and 1b at the welded connection region by the extension of a bladder 8. The thermoplastic material pushed inside when butted is pushed back outward.  By this welding pressure, a welded connection can be obtained which is strong and free of welding beads both on the inner and outer sides.
