Title: Petroleum combustion equipment
Inventor: TEI SHIYUNRO
IPC: F23D11/08
Filed: 1996-04-25
Abstract: PROBLEM TO BE SOLVED: To improve evaporation efficiency and combustion efficiency by forming an evaporation surface enlarging section in an inner burner body for directly evaporating sprayed liquid fuel without allowing the same to flow down along the evaporation surface. SOLUTION: Centrifugal force generated by the rotation of a spray tray 17 and a cover plate 20 driven by a driving motor 19 raises a liquid fuel along the inner wall of the spray tray 17, and sprays the same through a gap between the spray tray 17 and the cover plate 20 to form a radially spreading jet toward a mixing space, that is, an evaporation surface enlarging section 40c formed on a surface where an inner body 40 contacts the ground to generate uniform fine particles. The fine particles are evaporated as they come in contact with the evaporation surface enlarging section 40c of the inner body 40, which is heated by a preliminary heater 12 to an appropriate temperature for evaporation in advance.  Especially, the evaporation surface enlarging section 40c is formed in an uneven, triangularly threaded or spirall y uneven form, so that the fine particles sprayed onto the evaporation surface enlarging section 40c are directly evaporated without flowing down thereon to prevent tar from accumulating.

Filed: 1991-05-10
Abstract: PURPOSE:To prevent thermal decomposition and to obtain a dense sintered material in production of a sintered material of CaCO3 by sintering a powder raw material consisting essentially of CaCO3 under specifying sintering temperature and pressure of a high-pressure gas during sintering. CONSTITUTION:A powder raw material consisting essentially of CaCO3 such as coral sand is subjected to a pressed powder molding by cold work to give a molded article, which is burnt in a high-pressure gas atmosphere consisting essentially of an inert gas. In the operation, the burning temperature (t deg.C) is made in 900<=t<1,200 and pressure of the high-pressure gas (Pkgf/cm<2>) during burning is made in P>(6-600)<3.5>/4.7X10<8>. A sintered material having sufficient strength is not obtained when the burning temperature (t) is <900 deg.C and, on the other hand, CaCO3 is melted when the temperature is >=1,200 deg.C. Thermal decomposition of CaCO3 can be avoided by making the pressure P in the range.

Title: Method and device for measuring physical quantity distribution
Inventor: NAKAMURA TERUYUKI
IPC: G01D21/00
Filed: 1994-05-20
Abstract: PURPOSE:To eliminate distortion resulting from the incident waveforms of beams or the like by causing a neural network to learn a distribution of known physical quantities, and displaying a true value in that output or a physical quantity distribution that approximates the true value. CONSTITUTION:A means 3 for branching and separating light separates Stokes lines and anti-Stokes lines from each other that come from an optical fiber 4, and outputs both of the lines to respective light sensing circuits 5s, 5a. Both of the lines are subjected to averaging processing 7s, 7a, and a temperature distribution computing circuit 9 uses a converter circuit to convert the time distribution of backscattering intensities into a temperature distribution along the optical fiber, and this temperature distribution is displayed 10. In this case, the circuit 9 has a neural network that is connected to the converter circuit. If the true temperature distribution is varied in steps, for example, the converter circuit converts the temperature distribution into a temperature distribution of rounded waveforms including distortion resulting from the incident waveforms of beams, etc. The neural network learns a distribution of known physical quantities in advance so as to output the waveforms from which this distortion has been eliminated, and outputs a waveform that is almost the same as those of the true temperature distribution. This output serves as a temperature distribution as measured by the circuit 9.

Title: Method for treating molten slag of waste
Inventor: NISHIHARA NOBUYOSHI
IPC: C04B5/00
Filed: 1997-04-24
Abstract: PROBLEM TO BE SOLVED: To enable the securing of a chemically stable slag which is free from the eluation of heavy metals by first gasifying harmful heavy metals through melting the metals in a reductive atmosphere and separating the gasified heavy metals and converting a trace of residual heavy metals to a hardly soluble oxide after being exposed to the gas of the oxidative atmosphere for a bleaching action. SOLUTION: From the top of a melting furnace 1, an urban refuse as one of the examples of industrial waste, and coke and limestone as a secondary raw material are loaded. The ash and non-combustible material of the industrial waste, the coke and the limestone descend to the bottom part of the furnace 1 and the coke is burned, while the ash and the non-combustible material are turned to a molten state. The interior of the furnace 1 is in a reductive atmospheric state and most of the harmful heavy metals contained in a slag, e.g. lead fugaoiously vaporize. The molten slag unloaded from an unloading aperture is received into a molten slag oxidation trough 3. An air is directly blown into the interior of the slag and is allowed to reside there. Consequently, the slag becomes a fine sandy particle passing through water crushing facilities 5.  Thus the lead content of the slag obtained is controlled and a trace of the lead remaining in the slag is immobilized, so that its eluation level is below the lower limit of a specified quantity.
