Filed: 1985-11-07
Abstract: PURPOSE:To obtain fish meal efficiently in high yield without using blood water treatment, by mixing fish bodies with a specific organic solvent and contacting the mixed raw material with an extractant gas under specific condition. CONSTITUTION:Raw fish body is made to contact with an organic solvent compatible to water as well as a supercritical gas or a high-pressure liquefied gas. The organic solvent can form a homogeneous phase in a 3-component system of organic solvent, water and extractant gas under a specific condition and has protein denaturation activity. For example, it is ethanol, methanol, acetone, etc. The mixed raw material is made to contact with an extractant gas (e.g. carbon dioxide gas, dinitrogen monoxide gas, etc.) to effect the simultaneous or stepwise extraction of water, oil and fat and organic solvent from the mixed raw material. The extraction is carried out in a region (A) in which the organic solvent-water-extractant gas 3-component system forms a homogeneous phase or in a region (B) in which the organic solvent-water- extractant gas 3-component system forms binary phase. In the latter case, the amount of the organic solvent added to the system is selected in a manner that the final water-content of the extraction residue does not hinder the complete extraction of the oil and fat.

Abstract: PURPOSE:To prevent the generation of disappearance of a transparent electrode lead section by forming a metallic thin-film to a shape that it is superposed to a transparent electrode pattern and also coating an exposed transparent conductive film with a resist at the same time as a photo-resist pattern for forming a metallic lead electrode is shaped from the metallic thin-film and etching the metallic thin-film. CONSTITUTION:A transparent conductive film is formed in a region, in which a transparent electrode pattern must be shaped, on a glass substrate 10, a transparent electrode 21 is patterned, and a metallic thin-film 40 is evaporated by using Al, etc. The thin-film 40 is evaporated by employing a metallic mask because one part of a lead section 23 for the transparent electrode 21 is coated with the thin-film 40 and the evaporation is limited in a region, in which a metallic lead electrode 42 must be shaped. The precision of the superposition of the metallic thin-film 40 and the transparent electrode lead section 23 need not be improved because allowance can be taken in a contact section between the lead section and the metallic lead electrode by previously setting the lead section 23 for the transparent electrode in proper length, and a photo-resist pattern is shaped in a region 71. The metallic thin-film 40 is etched, and a resist is removed, thus obtaining an excellent pattern for the metallic lead electrode 42.

Filed: 1984-11-27
Abstract: PURPOSE:To smoothly perform the regeneration of a filter, by reducing the porosity of each cell wall of a filter having a honeycomb structure comprising porous ceramic at the end part of the exhaust gas outlet side of the filter as compared with that at the end part of the inlet side thereof. CONSTITUTION:Cells 2 having a honeycomb structure are formed of filter cell walls 1 comprixing porous ceramic and the end parts of the cells 2 are alternately closed by closure materials 3. The porosity of each cell wall is continuously reduced from the inlet end 45 of exhaust gas so that the porosity of the part of about 1/3 from the inlet end is 80%, that of the part of about 1/3 from the outlet end 5 is 70% and that of the central part is 80-70%. Therefore, the accumulation of soot begins from a pat having high parosity and, because the ignition characteristic at the time of regeneration is dependent on a soot accumulation state, the rising in the temp. of the filter is suppressed if ignition is performed from the front parts of the cells.
