Title: Color video camera
Inventor: ASAKAWA KATSUMI
IPC: H04N9/07
Filed: 1992-04-21
Abstract: PURPOSE:To obtain a satisfactory image including a small number of false colors even if a high frequency component is included in the luminance change of the image. CONSTITUTION:The output of a photoelectric transducer having N types of spectral sensitivity characteristic is inputted to the two-dimensional LPF 21-24 so that N types of output are obtained. The output signal of the picture element of the J-th spectral sensitivity characteristic (J: one of 1-N) added with the fixed value is multiplied by the ratio set between the output of the K-th two-dimensional LPF (K: one of 1-N) added with the fixed value and the output of the J-th two-dimensional LPF added with the fixed value in terms of the coordinates of the picture element. Then an arithmetic circuit 25 calculates a color signal from the output signal obtained when it is supposed that the calculated coordinates of the picture element includes the K-th spectral sensitivity characteristic and the output signal obtained when it is supposed that the picture elements of the spectral sensitivity characteristic except the K-th one are calculated as necessary in the same way.

Title: Method of igniting sludge coal
Inventor: TAKAHASHI YUKIO
IPC: C10L9/00
Filed: 1985-05-13
Abstract: PURPOSE:To provide a method of igniting sludge coal capable of maintaining a stable combustion in a fluidized bed by a method wherein fine clay constituent contained in the sludge coal is removed in advance. CONSTITUTION:Each of the sludge coal with its clay constituent being removed and the sludge coal with its clay constituent not being removed is formed to have a size of 8 phiX8mm, respectively, and ignited in an electric furnace kept at a temperature of 800 deg.C every specified time. As a result of comparison of their rates of combustion, a mere removal of fine clay constituent dispersed in the water causes the time for reaching a rate of combustion of 100% to be reduced to a half of that of not removing of the clay constituent, resulting in showing a substantial effect. A result of comparison between a hardness of the sludge coal during its dry condition and another hardness of ignited ashes at a temperature of 800 deg.C in reference to their crushing strength shows that the sludges removing the fine clay constituents becomes quite weak in its strength. This shows that in case of ignition in the fluidized bed, even if the sludges are fed in the lump form, the lumps reduces into powder as the combustion is proceeded in the furnace and then a mean diameter of the medium does not increase any more.
