    Abstract: PROBLEM TO BE SOLVED: To provide an exhaust after-treatment filter capable of preventing hot spot meltdown from occurring. SOLUTION: This filter and method for after-treatment of exhaust are used for filtrating exhaust emission from an engine. Varing cell size is provided to distribute trapped contaminated particles along a distribution pattern for reducing the risk of melting of trapped contaminated particulates during heat concentration and regeneration or minimize the possibility of hot spot meltdown caused by the densely concentration of the trapped particulates. The cell size can be varied by varying a volume and/or a height and/or a width and/or a length. Tapered cell provides a change in cross sectional area at an upstream end part toward a downstream end part.

    Abstract: PROBLEM TO BE SOLVED: To provide a high-temperature composite ceramic filter applicable as a filter for exhaust gas of a diesel engine. SOLUTION: This high-temperature commposite ceramic filter medium consists of large numbers of ceramic fibers, which are arranged at random and the surfaces and the crossing parts of which are coated with silicon carbide, and has high-temperature withstanding property, durability and improved performance. The composite ceramic filter medium is obtained by forming a sheet from the slurry containing a ceramic fiber, an organic fiber and a water-soluble thermoplastic binder, drying the sheet, fabricating the dried sheet into a three- dimensional green filter structure, applying any of the aqueous solution of a thermosetting resin and the colloidal solution of a ceramic material to the filter structure for enhancing the thermal stability of the green filter structure by hardening the binder, firing the obtained filter structure at the high temperature enough to remove the organic component and coating the fired filter structure with silicon carbide by chemical vapor deposition method.

    Abstract: PROBLEM TO BE SOLVED: To provide a fuel filter assembly that has a fuel transfer pump and has a water separating characteristic. SOLUTION: The fuel filter assembly 20 has an outer shell 21. A first end of the outer shell 21 has a fuel inlet passage 39, a fuel outlet passage 40 and a water collecting region 35, and a second end thereof is closable by a removable lid 22. A fuel filter cartridge 23 is disposed in the outer shell 21. The cartridge has a filter element 63 for filtering out water. A fuel transfer pump 42 is disposed in an internal space 38 of the filter element 63. An operation of a plunger 78 causes a filter detector control circuit to prevent fuel delivery to a downstream position unless the fuel filter cartridge is disposed properly.

    Abstract: PROBLEM TO BE SOLVED: To provide a corn stack centrifugal separator for separating a granular material from circulating liquid. SOLUTION: A base assembly contains a liquid inlet 82, a 1st passage 83 and 2nd passages 84, 85. The liquid inlet 82 is connected to a hollow base hub 87 through the 1st passage 83, bearing devices 34, 35 are positioned between a rotor hub and a shaft center tube so as to rotate a corn stack assembly, an impulse turbine wheel is attached to the rotor hub and flow jet nozzle 27, 28 are directed to the turbine wheel. The flow jet nozzles are respectively connected to the 2nd passages 84, 85 so as to direct the flow jet of liquid to the turbine flow to apply the rotating movement to the corn stack assembly and the liquid from the flow jet nozzles enters to the centrifugal separator through the 2nd passages. The liquid further circulated through the corn stack assembly is provided from the same liquid inlet.

    Abstract: PROBLEM TO BE SOLVED: To provide a self-propelling centrifugal separator for separating a granular material from a circulating liquid. SOLUTION: The centrifugal separator comprises a pair of jet nozzles (34) in the tangent line directions for generating self-propelling force. A centrifugal separator shell (28) is joined to a base (29) for defining the space in a hollow inside and a disposable liner is positioned in the centrifugal separator shell. A hollow rotor hub (22) is assembled in the base (29) and extended through the space of the hollow inside. A supporting plate (33) is positioned in the space of the hollow inside and defines a circular flow outlet in corporation with the rotor hub (22). A unitary separation blade module (21) is installed in the space of the hollow inside so as to surround the circumference of the rotor hub (22). The separation blade module (21) comprises a plurality of separation blades extended at intervals from one another in the axial line directions.

    Abstract: PROBLEM TO BE SOLVED: To provide a fluid filter constituted so as to facilitate the attachment and detachment of a filter assembly, and an apparatus having the fluid filter mounted therein. SOLUTION: The fluid filter has a filter element (27) for filtering a fluid and a nut plate (22) is locked with a filter head by a screw. An inside seal retainer is positioned between the nut plate (22) and the filter element (27) to form a hollow interior. The inside seal retainer has at least one strong hollow web and this web forms a space for transmitting the fluid to the gap between the nut plate (22) and the filter element (27). An inside deformation direction seal is attached to the inside seal retainer and the filter element (27) is hermetically sealed by the filter head.
