    摘要: The present invention is done on the basis of knowledge obtained from experimental results shown in FIG. 1 with respect to a heat recovery method from gasified products of hydrocarbon. The heat recovery method from gasified products of hydrocarbon of the invention is to introduce the gas containing oily matters produced by gasification of hydrocarbon into the fluidizied bed where heat is recovered by indirect heat exchange between said product gas and the cooling agent passing through the heat transfer tube arranged in the fluidized bed, in which said product gas is passed through high temperature fluidized bed kept at about 450.degree.-500.degree. C. and then through the low temperature fluidized bed kept at about 250.degree.-300.degree. C. successively and that the heat of said product gas is recovered by heat exchange in said high temperature fluidized bed and low temperature fluidized bed respectively. The heat recovery method by the invention is able to increase the heat recovery quantity of product gas by the fluidized bed heat exchanger and remarkably decrease the possibility of plugging by coking at the gas cooling.

    摘要: The aperture correction system variably adjusts a correction efficient value based upon a sign and an original relative light intensity value or its equivalent. Because the correction is relative light intensity sensitive, the aperture correction is optimized, and the average light intensity is maintained before and after the aperture correction for natural appearance of the image.
