  • Patent number: 9547235
    Abstract: An imprint lithography method is disclosed for forming a patterned layer from an imprintable liquid medium on a substrate by means of an imprint template having a patterned surface. The method involves contacting the patterned surface and imprintable liquid medium together for a filling period. Light emergent (e.g., scattered or reflected) from an interface between the medium and the patterned surface is collected and measured during the filling period to obtain data concerning one or more voids at the interface, and an estimated end time for the filling period is derived from a relationship between the data and time. The method may allow subsequent process steps to be undertaken more rapidly, with reduced risk of defects arising from remnants of unfilled voids. An imprint lithography apparatus and component for putting the method into effect are also disclosed.

  • Publication number: 20140217064
    Abstract: It is an object to manufacture a composite of a metal part and a resin composition part, which is improved so as to securely join and integrate stainless steel and a resin. A stainless steel part whose surface has been suitably roughened by chemical etching or the like can be used. An integrated product is obtained by inserting a stainless steel piece 1 with its surface treated into a cavity formed by a movable-side mold plate 2 and a fixed-side mold plate 3 of a metallic mold for injection molding 10 and injecting a specific resin. PBT, PPS or an aromatic polyamide resin can be used as the main resin component of a resin composition 4 that is used. High injection joining strength is obtained if the resin composition contains, as an auxiliary component, PET and/or a polyolefin resin in the case of PBT, a polyolefin resin in the case of PPS and an aliphatic polyamide resin in the case of an aromatic polyamide resin.

  • Patent number: 8790528
    Abstract: Selective etching techniques are used to manufacture a basic filtration element, which can then be used as a basis for constructing various devices for different applications. In this process, sheets of etchable material are etched from one or both sides of that sheet to form channels in a premasked pattern, which controls the minimum opening of the filtration element. The desired channel opening is only limited by the capability of the photochemical etching system being used. Alternatively, a filter element may be made by rolling or extruding a first sheet to form a plurality of recessed areas bordered by lands, selectively etching or punching through the recessed pattern areas, and bonding a second sheet having a plurality of etched or punched through areas to the first sheet, and, aligning the etched through areas to the second sheet with the recessed areas of the first sheet.
