| 20080210383 | BONDING DEVICE - A bonding device that is not affected by heat and that is capable of maintaining wafers to be bonded parallel to each other so as to increase and stabilize the accuracy with which the wafers are bonded. A first space is formed between a first block member and a first pressure shaft, and a second space is formed between a second block member and a second pressure shaft. In this way, little heat is transferred from the first block member and the second block member to the first pressure shaft and the second pressure shaft, respectively, and therefore, a substantially uniform temperature is maintained inside the first block member and the second block member. Stresses caused by a difference between thermal expansion of the first block member and the second block member and thermal expansion of the first pressure shaft and the second pressure shaft are relieved by deflection of the first support pillar members and the second support pillar members. In this way, the flatness of a surface of the first block member for grasping a first wafer and the flatness of a surface of the second block member for grasping a second wafer can be maintained. | 09-04-2008 |
| 20090139661 | PVC/CPVC Composite Pipe With Metal Interlayer And Process For Making It - A composite pipe has a metal conduit sandwiched between inner and outer conduits of PVC/CPVC, each of which are adhesively secured to the interlaying metal conduit with a dried, solvent-free thin layer of a thermosetting bilayer adhesive which provides a bond with the metal, which bond fails in cohesive failure. Narrowly defined limits on the thickness of each conduit are found to provide a bendable composite pipe with an aluminum interlayer; and to provide a rigid non-bendable composite pipe with a steel interlayer. Making the composite pipe which meets required ASTM and NSF test considerations requires unexpectedly critical process steps. A process for making the pipe is disclosed, as are PVC/CPVC fittings which allow lengths of pipe to be solvent-cemented in them so as to seal the terminal ends of the pipe against infusion of fluid under pressure in the pipe, thus preventing delaminaton. | 06-04-2009 |
| 20090294073 | SUBSTRATE PROCESSING APPARATUS - To provide a substrate processing apparatus capable of uniformly processing substrates without applying excessive force to the substrates and without being affected by the standing time. The substrate processing apparatus includes a holding portion | 12-03-2009 |
| 20090321020 | MANUFACTURING MACHINE OF PACKING MATERIAL INFLATED WITH AIR - The present invention is applied to a shock-absorbing packing material inflated by air and relates to an apparatus for manufacturing the shock-absorbing packing material, polystyrene plastic that is used now as a shock-absorbing material becomes difficult to use because of environmental pollution, so that a shock-absorbing means that are formed by compiling plastic films or sheets, bonding them using heat or high frequency, and then inflating it by injecting air are used. However, it was difficult to develop an apparatus for manufacturing these shock-absorbing means, so that apparatuses that substantially have economical efficiency were not in the market. Accordingly, the invention provides an apparatus for manufacturing a shock-absorbing material with economical efficiency, which improves productivity without looseness or extension, although plastic sheet or films rolled on a plurality of rolls are bonded by heat at a constant interval while unrolling. | 12-31-2009 |
| 20100200170 | METHOD AND APPARATUS FOR STRINGING THIN FILM SOLAR CELLS - The present inventions generally relate to thin film solar cell fabrication, and more particularly, to techniques for interconnecting solar cells based on Group IBIIIAVIA thin film semiconductors. In a particular embodiment, a system is described that positions solar cells and conductive leads with respect to each other so that application of a conductive adhesive and formation of an assembled solar cell string, followed by curing and cooling of the conductive adhesive, can occur in a repeatable manner. | 08-12-2010 |
| 20120067526 | Process of Thermal Transfer Using Hot Melt Adhesive Lamination for Forming a Carpet Backing and Finished Carpet or Tile Product - A method for binding a greige carpet and a secondary backing material using a hot melt adhesive is disclosed. A heated application roll may be provided and the secondary backing material may be contacted with the hot melt adhesive and greige carpet and pressed against the heated application roll. | 03-22-2012 |
| 20130299094 | METERING SYSTEM FOR APPLYING A COMPOSITION TO A ROLL AND METHODS OF OPERATING SAME - An adhesive metering system for applying an adhesive to an anilox roll is provided. The anilox roll includes cups embedded within a peripheral surface of the anilox roll. The system includes a pan having a first end, a second end, opposing sidewalls, and a bottom configured to form a trough to partially receive the peripheral surface. A first blade is coupled to the first end, wherein the first blade has an edge spaced from the cups by a gap defined between the peripheral surface and the edge. The system further includes a pump coupled to the pan and in flow communication with the first blade and the trough. The pump is configured to discharge the adhesive into the trough and on the first blade wherein the first blade is configured to facilitate channeling adhesive into the cups of the anilox roll. | 11-14-2013 |
| 20150107777 | METHODS AND APPARATUS FOR TRANSPORTING ELASTOMERIC EMITTERS AND/OR MANUFACTURING DRIP LINES - Methods and apparatus for transporting or delivering elastomeric emitters and inserting elastomeric emitters into drip line are disclosed herein, and more particularly, to methods and apparatus for manufacturing drip line to form an irrigation assembly or system. In one form, the apparatus comprises a feeder, conveyor, emitter drive mechanism and guide bar for insertion into an extruder to bond the elastomeric emitter to an inner surface of the extruded tube. Friction reducing apparatus and methods are further disclosed as well. | 04-23-2015 |
| 20160031153 | Seal Device - A seal device includes a medium passage that sends a heating medium to a sealing units, the medium passage includes a heating medium passage portion for sending a heating medium to said communication part so as to heat the pressing part, a cooling medium passage portion for sending a cooling medium to the communication part so as to cool the pressing part, and a passage switch unit that switches between a state in which the heating medium passage portion and the communication part are connected, and a state in which the cooling medium passage portion and the communication part are connected. | 02-04-2016 |
