Title: Liquid fuel burning device
Inventor: MORIGAMI KAZUHISA
IPC: F23D11/10
Filed: 1990-01-11
Abstract: PURPOSE:To completely gasify a liquid fuel in a gasification cylinder by a method wherein the side walls of a gasification cylinder are projected outward and two constrictions are provided, and at the same time a projection of a specified size is prepared on the bottom part between the constrictions. CONSTITUTION:An upward projection 10 is provided on the bottom part between first and second constrictions 8 and 9 formed by projecting the side wall near the central part in the longitudinal direction of a gasification cylinder 5, and its width is approximately equal to or larger than the width of the flow path of the constriction 8. The fuel atomized and ejected from a nozzle 1 drops upon the bottom plate of the gasification cylinder 5 and begins gasification, which is continued while the fuel is converged toward the central part. Even if a part of the liquid fuel remains ungasified, it is branched at the projection 10, gasified, converged again toward the central part at the constriction 9, and finishes its gasification. On the other hand, an air necessary for combustion repeats compression and expansion at the constriction 8, projection 10, constriction 9, and is well mixed with gasified gas to give a premixed gas. By this procedure, the combustion is stabilized, and at the same time the ejected fuel is prevented from forming tar within a gasification cylinder.

Abstract: PURPOSE: To eliminate the sticking of carriers to an image carrier, to make a deterioration in the carriers slow and to reduce the consumption of toner by making speed for rotating a developing sleeve lower, when an image region does not pass in front of the developing sleeve. CONSTITUTION: The number of rotations of a developing sleeve 41 and the driving shafts of stirring screws 43A-43C is changed by the control of a developing unit driving system capable of consecutively changing the speed. The operation control of the developing unit driving system is executed by a process CPU. When the image region does not pass through a part where a photoreceptor drum 1 faces the developing sleeve 41, the number of rotations of the sleeve 41 is set to 100rpm for instance and when the image region passes through the part where the photoreceptor drum 1 faces the sleeve 41, the number of rotations of the sleeve 41 is set to 250rpm for instance. Thus, the image region does not pass in front of the sleeve 41, the speed for rotating it is made slower than that when the image region passes in front of the sleeve 41, while a voltage is applied thereto.

Abstract: PURPOSE: To obtain the identification result which is identical to that obtained through the human eyes for the colored pictures by utilizing the colors and the positional relation.  
     CONSTITUTION: For the input picture, the 3-dimensional histogram is produced based on the luminosity and chromaticity and then divided into regions of different luminosities. And the comparison is given among the threshold levels designated to each region, and the region featuring the highest level is extracted for leveling. And then the extraction control process is carried out to detect the adjacency to the region in the immediately preceding process part space, and then the picture element of the picture corresponding to the process part space is extracted to carry out the leveling process. These processes are carried out from the space of low luminosity to those of higher luminosity in sequence, and at the same time the extraction results are piled on to each other. When such extraction and leveling complete, the extraction result is read out of picture memory 1024 and then undergoes the expansion process through expansion process unit 1025 to be then applied to picture memory 1028. The contents of memory 1028 is transferred to memory 1024 to repeat the expansion process.

IPC: B32B5/18
Filed: 1997-01-16
Abstract: PROBLEM TO BE SOLVED: To make a contraction prevention effect of a ceramic green sheet due to a plastic film for constraint and punching workability compatible. SOLUTION: After a plastic film 12 for constraint is stuck to the upper surface of a ceramic green sheet 11 before punching working, a carrier tape on the lower surface of the ceramic green sheet 11 is peeled and punching working is performed. The plastic film 12 for constraint uses a foaming plastic film in which porosity is 15 to 40%. A infinite number of small pores formed in the film of this plastic film 12 for constraint perform their duties of lowering shearing strength and improving punching workability, and when porosity is 15% or more, a hole clogging generation ratio of a punching hole 14 becomes 0%. When porosity is too high, mechanical strength is lowered and contraction prevention effect of the ceramic green sheet 11 is lowered. When porosity is 40% or below, a coefficient of contraction becomes 0.02% or below.
