The circulation sludge is ejected by the liquid/gas ejector 7 from a throat 11 to mix with the oxygen-containing gas. The sludge is passed through the liquid/liquid ejector 8 and the downpipe 9 while effectively dissolving oxygen therewith to perform aerobic digestion. The oxygen-containing gas humidified with the humidity component-containing gas such as an exhaust ozone gas is supplied to an induction chamber 13 from a line 34, thus preventing the induction chamber 13 from being closed by drying and solidification of the sludge.  <P>COPYRIGHT: (C)2004,JPO&NCIPI

Abstract: <P>PROBLEM TO BE SOLVED: To provide new metal powder which can form an anisotropic conductive film having more excellent anisotropic conductivity than heretofore, to provide its production method, and to provide an anisotropic conductive film which is sufficiently adaptive to the request for higher density packaging by using the metal powder.  <P>SOLUTION: The metal powder has a shape where many fine metal grains are connected so as to be a straight chain shape free from branching. Further, the maximum value of angles between the tangents in both the ends of a curve obtained by approximating the shape of the chain and a straight line connecting the space between both the ends of the curve is regulated to ≤20°. In the production method, from a magnetic field-applied liquid in a substantially non-stirred static state comprising metal ions to form the metal grains, a reducer and a dispersant, the metal ions are reduced by the action of the reducer to precipitate the metal grains, and the many metal grains are connected so as to be a straight line by the magnetic field to form the metal powder. The anisotropic conductive film comprises the metal powder in which the length of the chain is regulated to less than the distance between the adjoining electrodes composing conductively connected joints in a state of being oriented to the thickness direction of the film.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: <P>PROBLEM TO BE SOLVED: To heighten the thermal efficiency of a secondary heat exchanger in a heat exchanger of a gas hot water supply heater including a primary heat exchanger and a secondary heat exchanger.  <P>SOLUTION: In a fin tube 6 of the secondary heat exchanger 4 disposed above the primary heat exchanger 3, circular flange-like fins 62 making a turn around the tube is projected at substantially equal spaces on the outer periphery of a metal tube 61 in the longitudinal direction of the tube 61. Each fin 62 is a hollow body integrally connected to the tube. The sectional shape of the fin 62 is such that the outer peripheral edge is pointed substantially triangular, and the inside of the fin is connected to the inside of the tube. Even if on the surface of the fin tube, water in exhaust gas is condensed to cause dew condensation, water drops adhering to the fin are collected at the lower end of the fins through the fins and quickly dropped from the tips of the pointed fins. Accordingly, the water drops can be prevented from remaining on the surfaces of the fins for a long time to lower the heat exchange efficiency of the fins.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
