| 20090078643 | Low off-gassing polyurethanes - A low out-gassing polyurethane is described for use in applications where contaminants must be kept to very low levels, such as during lithography. In particular, the polyurethane is essentially free of silicon-containing species, which present particular contamination problems in the context of electronic device manufacturing. The polyurethane may be utilized as a potting material in filter assemblies, or in other contexts within the environment of electronics manufacturing. Testing of the novel polyurethane formulation shows the off-gassing characteristics to be much lower than commercially available potting materials made from polyethylene. | 03-26-2009 |
| 20090084727 | Band type filter - According to an aspect of the present invention, there is provided a filter including: a belt shaped frame formed of a resin, an opening being provided inside the frame; a pair of link portions formed on the frame at both distal ends thereof to be engagable with each other; and a filtering member provided in the opening, wherein the frame is formed to have a flat plate shape or a curved shape that has a center angle equal to or less than 180 degrees in a state where the pair of link portions are not engaged, and wherein a plurality of grooves are formed on at least one surface of the frame at intervals along the longitudinal direction. | 04-02-2009 |
| 20090200229 | Lattice Structure, Use of the Lattice Structure and Vessel With Lattice Structure - A lattice structure for the passage of a first medium against a second medium with transverse webs and longitudinal webs, lattice openings with a clear width of ≦300 μm being arranged between the transverse webs and the longitudinal webs. On at least one side of the lattice structure, the transverse webs and/or the longitudinal webs have a rib arrangement of ribs projecting vertically to the lattice plane, at least one first group and a second group of ribs being arranged which differ from one another at least by their heights H | 08-13-2009 |
| 20110084018 | RING FILTER - A ring filter with a frame and a filter fabric. The frame has two axially spaced apart ring-shaped frame elements which are connected to one another by transverse struts. Between the frame elements and the transverse struts the filter fabric is arranged, and frame has two open ends which are located opposite each other in the circumferential direction. | 04-14-2011 |
| 20110100901 | IMPROVED FILTERING DRUM FOR FIBRE SUSPENSIONS IN WATER - The invention concerns a filtering drum ( | 05-05-2011 |
| 20120097601 | MODULE CASE AND HOLLOW FIBER MEMBRANE MODULE USING THE SAME - A hollow fiber membrane module is disclosed, which is capable of preventing a bundle of hollow fiber membranes from being separated from a module case, the hollow fiber membrane module for accommodating a bundle of hollow fiber membranes closely held together through the use of potting agent, including a module case including: a first inner surface serving as a projection on which the bundle of hollow fiber membranes is stably placed; a second inner surface upwardly extending from one end of the first inner surface, the second inner surface including at least one separation-preventing groove to prevent the bundle of hollow fiber membranes from being separated from the module case; a third inner surface downwardly extending from the other end of the first inner surface; and a fourth inner surface connected to the third inner surface. | 04-26-2012 |
