Title: Sealing liquid feeding method for nash hytor pump
Inventor: INOUE SADAO
IPC: F04C19/00
Filed: 1981-06-02
Abstract: PURPOSE:To reduce the amount of chemicals used for generating SO2 gas, by reusing sealing liquid by connecting an inlet port and an outlet port for the sealing liquid of a pump via a circulating passage, and reducing the difference of the density of SO2 gas in the sealing liquid in feeding SO2 gas under pressure by the sealing liquid. CONSTITUTION:Waste liquid after use in Nash Hytor pumps 1 is carried back to  a circulating tank 15 via a return passage 16, and sealing liquid in the tank 15 is in turn carried to a head tank 10 by means of pumps 17. Sealing liquid cooled in the head tank 10 is delivered again to the Nash Hytor pumps 1 via a supply passage 7. That is, in feeding SO2 gas under pressure by sealing liquid, part of SO2 gas is absorbed in the sealing liquid, and the sealing liquid is reused while causing the following chemical reaction, SO2+H2O=H2SO3 (diluted sulfuric acid). Since, by employing such an arrangement, the difference of the density of SO2 gas in the sealing liquid at the inlet port and the outlet port of the sealing liquid is reduced extremely, the amount of chemicals such as H2SO4 used for generating SO2 gas can be reduced considerably.

IPC: H04N1/40
Filed: 1990-03-31
Abstract: PURPOSE:To separate a dot area with much higher accuracy without erroneously separating the cross point of a line in a character at a comparatively higher density level as the projecting peak of a dot by detecting the peak of the dot according to the size of the minimum value of the density level in the area close to an attention picture element. CONSTITUTION:When a density level Lx of a central picture element X is maximum in respect to the density level of a nearby picture element and a minimum value Lmin of the density level of the nearby picture element is smaller than a threshold value Lth in the matrix of 3X3, a projecting peak picture element detection part 2 defines the central picture element X as the projecting peak picture element of the doe area and when the density level of the central picture element X is minimum to the density level of the nearby picture element, the picture element is detected as the recessed peak of the dot area. A temporary dot picture element detection part 3 counts the numbers of the projecting peak picture elements and recessed peak picture elements in the detected dot area for the unit of the 5X5 matrix and when the number is larger than a threshold value Kth, the central picture element of the above mentioned matrix is defined as a temporary dot picture element. A dot area separation part 4 separates the dot area from the two-dimensional position information of the peripheral picture element of the temporary dot picture element.

Filed: 1980-06-26
Abstract: PURPOSE: To increase the burning efficiency as well as to save a fuel, by atomizing and mixing a liquid fuel such as kerosene, heavy oil or the like and water, and burning the fuel.  
     CONSTITUTION: A burning cylinder 1 is preheated by an auxiliary burner 16, and in this state a liquid fuel is fed into a vaporization chamber 4 via an oil feeding pipe 3 to vaporize. The vaporized fuel is pumped via an oil delivering pipe 5 into a gas mixing chamber 7. On the other hand, the water supplied into a water supplying pipe 6 that spirally extends along the inner surface of the burning cylinder 1 is heated and vaporized, and this vapor is also pumped into the gas mixing chamber 7. Thus, the vaporized fuel is mixed and gasified such that an oil film is formed on each water vapor particle. The resulting gaseous fuel is passed via a pressure adjusting chamber 9 and a gas chamber 10 to a nozzle 13 through which the fuel is jetted and is burned by the preheated air in the preheating cylinder 15.
