Patent number: 7147743Abstract: An energy-beam-curable thermal-releasable pressure-sensitive adhesive sheet having, on at least one side of a base material, an energy-beam-curable thermo-expandable viscoelastic layer containing thermo-expandable microspheres and a pressure-sensitive adhesive layer stacked in this order. The pressure-sensitive adhesive layer has a thickness of about 0.1 to 10 ?m and can be formed from a pressure-sensitive adhesive. The energy-beam-curable thermo-expandable viscoelastic layer, on the other hand, can be formed from a tacky substance. The energy-beam-curable thermal-releasable pressure-sensitive adhesive sheet according to the invention has adhesion enough to withstand a carrying step of an adherend, causes neither winding up of the adhesive nor chipping upon cutting and facilitates peeling and collection of cut pieces after cutting. In addition, it exhibits low contamination on the adherend after peeling.Type: GrantFiled: October 17, 2001Date of Patent: December 12, 2006Assignee: Nitto Denko CorporationInventors: Kazuyuki Kiuchi, Toshiyuki Oshima, Akihisa Murata, Yukio Arimitsu

Patent number: 7144471Abstract: A bonding method and apparatus for performing same in which a first member (e.g., a silicon chip) is bonded to a second member (e.g., a glass substrate such as a PCB) using a thermosetting resin adhesive. Near infrared rays are directed onto the second member, some of these passing through the second member to also heat the adhesive. A heater is pressed onto the first member and also heats the first member. Selective cooling is also utilized to assure an acceptable temperature gradient between both members and thereby prevent distortion of same which could harm the resulting structure.Type: GrantFiled: February 6, 2002Date of Patent: December 5, 2006Assignee: International Business Machines CorporationInventors: Shigetaka Kobayashi, Takeshi Yamada, Masaki Hanada

Patent number: 7135086Abstract: A glass substrate of a display panel onto which an organic electroluminescence (EL) element or the like is formed is sealed by affixing the glass substrate and a sealing glass via an adhesive therebetween. During this process, a pressure is applied between the glass substrate and the sealing glass so that a gap between the affixing surfaces achieves a target value and the adhesive is cured. The pressure is changed over time based on conditions such as the viscosity of the adhesive so that quick and precise sealing by the adhesive can be achieved.Type: GrantFiled: June 27, 2002Date of Patent: November 14, 2006Assignee: Sanyo Electric Co., Ltd.Inventor: Hideki Matsuoka

Patent number: 7074295Abstract: A method of correcting defects in a label resulting from a non-uniform application of adhesive to a surface of the label prior to applying the label to a container includes the steps of applying an adhesive to a surface of a label in a non-uniform manner to cause sections of the surface to be substantially devoid of the adhesive, and after applying the adhesive, applying a fluid in these latter sections to substantially fill them. The fluid is applied either onto the container in regions that are aligned with the label sections that are devoid of adhesive, or is applied directly onto the adhesive-free label sections. An apparatus for carrying out the above method also forms a part of the present invention.Type: GrantFiled: January 16, 2004Date of Patent: July 11, 2006Assignee: Applied Extrusion Technologies, Inc.Inventors: Bryan Bellafore, Paul D.

Patent number: 7067032Abstract: A tubular coupling element for producing a glued joint with a fluid line and a method for producing such a glued joint. The coupling element includes an inner tube that is insertable into a fluid line and an outer tube that is constructed concentric to the inner tube and integrally connected to the rear end of the inner tube by a connecting wall. An annular gap is present between the two tubes and is designed to receive an end section of the fluid line and a hot-melt type adhesive in a compacted solid form shaped as a ring. A connection between the coupling element and the fluid lines can be easily established by first introducing the adhesive in the annular gap and then melting it by rapidly supplying heat while the end section of the fluid line is pressed into the annular gap of the coupling element.Type: GrantFiled: September 9, 2000Date of Patent: June 27, 2006Assignee: A.

Patent number: 7063760Abstract: A method for laminating glass sheets wherein laminating film is placed over one surface of a first glass sheet and the film is heated with microwave radiation to a bonding temperature. Heated areas of the film are successively pressed to the glass sheet in a continuous manner for purging air from between the film and the first glass sheet and for applying bonding pressure. The pressed film areas are then cooled whereby an appropriate bond is attained between the film and the first glass sheet. Thereafter the first glass sheet with its bonded film is subjected to a partial vacuum and a second glass sheet is positioned on the film and the second glass sheet is pressed to the film. The film is then reheated with microwave radiation to a bonding temperature and thereafter cooled whereby an appropriate bond is obtained between the film and the second glass sheet to provide a glass lamination.Type: GrantFiled: March 17, 2004Date of Patent: June 20, 2006Assignee: Gyrotron Technology, Inc.Inventors: Vladislav Sklyarevich, Mykhaylo Shevelev

Patent number: 7029550Abstract: An energy-beam-curable thermal-releasable pressure-sensitive adhesive sheet has, on at least one side of a base material, an energy-beam-curable viscoelastic layer and a thermo-expandable pressure-sensitive adhesive layer containing thermo-expandable microspheres stacked in this order. The energy-beam-curable viscoelastic layer is, for example, composed of a composition of an organic viscoelastic body and an energy-beam-curable compound or an energy-beam-curable resin. The energy-beam-curable viscoelastic layer has a thickness of about 5 to 300 ?m or may be not greater than the maximum particle size of the thermo-expandable microspheres. The energy-beam-curable thermal-releasable pressure-sensitive adhesive layer according to the invention has adhesion enough to withstand a carrying step of an adherend, causes neither winding up of the adhesive nor chipping upon cutting and facilitates peeling and collection of cut pieces after cutting.Type: GrantFiled: October 17, 2001Date of Patent: April 18, 2006Assignee: Nitto Denko CororationInventors: Kazuyuki Kiuchi, Toshiyuki Oshima, Akihisa Murata, Yukio Arimitsu
