Patent number: 6291369Abstract: A soft, meshed, electromagnetic shielding textile sheet is placed in a mold, and the mold is clamped. The soft, meshed electromagnetic shielding textile sheet is shaped so as to conform with the inner surface of the mold when the mold is clamped. Therefore, it is not necessary to fabricate beforehand any insert of a shape corresponding to that of the inner surface of the mold. Since the meshed, electromagnetic shielding textile sheet is impregnated with part of a resin injected into the mold to form an injection-molded resin body, the adhesion of the electromagnetic shielding textile sheet to the injection-molded resin body is improved.Type: GrantFiled: April 5, 1999Date of Patent: September 18, 2001Assignee: Dai Nippon Printing Co., Ltd.Inventors: Masahiro Yoshikawa, Katsumi Kameda

Patent number: 6170116Abstract: An abrasive member and a cleaning device for a probe needle of a probe card are obtained which are capable of simplifying an operation of cleaning a probe needle of a probe card and also eliminating the step of employing an organic solvent or the like in the probe needle cleaning operation to improve the operating environment. In the cleaning device for a probe needle of a probe card, an abrasive member for a probe needle includes first and second fiber materials formed of at least one selected from the group consisting of a metal fiber, a carbon fiber and a ceramic fiber. The first and second fiber materials extend in different directions and are fixed to each other at a region thereof. A surface of abrasive member is provided with a space having approximately the same width as the width of the tip of a probe needle.Type: GrantFiled: April 13, 1998Date of Patent: January 9, 2001Assignee: Mitsubishi Denki Kabushiki KaishaInventor: Masaharu Mizuta

Method of electroconductive fastening of current collectors and terminals in electrochemical devices
Patent number: 6080267Abstract: A method of electroconductive fastening of electroconductive materials in electrochemical devices, where a sheet of metal or a sheet of electrically conductive fibers is to have a second sheet joined thereto which can be of solid sheet metal, and where at least one tape with an adhesive layer thereon is placed on top of one of the sheets, with the adhesive layer facing the sheets, and the assembly is subjected to pressure, and the adhesive layer is activated, causing the sheets to fasten together in electroconductive contact, and wherein a second tape with an adhesive layer facing the sheets may be applied from the other side prior to pressure application.Type: GrantFiled: February 12, 1999Date of Patent: June 27, 2000Assignee: Lithium Technology CorporationInventors: Stephen F. Hope, Joseph B. Kejha -
Patent number: 6054205Abstract: The invention provides a glass fiber facing sheet for engineered surfaces such as cement boards which reduces the pitting associated with open mesh glass scrims. The glass fiber facing sheet comprises an open mesh glass scrim having a plurality of intersecting continuous multifilament yarns which are bonded at their crossover points to provide dimensional stability to the scrim. A melt blown polymer web is preferably joined to one face of the glass scrim and covers the mesh openings in the scrim. The opposed face of the scrim defines an exposed grid profile surface which is available for mechanical interaction between the scrim and the cementitious slurry used in cement boards. In cement boards, the glass fiber facing sheet of the present invention is preferably mechanically integrated into a surface portion of the cement core along the exposed grid profile of the scrim.Type: GrantFiled: May 29, 1997Date of Patent: April 25, 2000Assignee: Clark-Schwebel Tech-Fab CompanyInventors: Nicholas S. Newman, Gordon L. Brown, Jr., R. Bruce Hinton, Andrew D. Broadway, Chia-Te Chou

Patent number: 6029327Abstract: The invention relates to the field of forming fibrous structures by needling processes. A process is provided for achieving a desired Z-fiber distribution in a fibrous structure by controlling transport depth during formation of the fibrous structure in a series of needling passes. Each needling pass generates a portion of Z-fiber bundles that penetrate adjacent fibrous layers, the Z-fiber bundles penetrating only those adjacent fibrous layers that need more Z-fiber bundles to attain a predetermined number of Z-fiber bundles within each fibrous layer.Type: GrantFiled: October 4, 1995Date of Patent: February 29, 2000Assignee: The B.F. Goodrich CompanyInventors: Philip William Sheehan, Ronnie Sze-Heng Liew

Patent number: 5885908Abstract: An anisotropic elastic web, particularly an anisotropic elastic film layer having a machine direction and a cross direction and having a thickness of from 20 to 300 microns formed of an extruded blend of a block copolymer elastomer portion and a polyolefin polymer portion blended in a ratio of from 10:1 to 0.4:1, respectively. The elastomer portion generally is a block copolymer elastomer formed of A blocks and B blocks, the A blocks are formed predominately of monoalkenyl arene and the B blocks are formed predominately of conjugated diene. The polyolefin portion is comprised predominately of an inelastic fiber forming polyolefin polymer, copolymer or blend. The anisotropic film layer has a F10 force Ratio (MD to CD) of at least 1.5. This anisotropic elastic web is usable in a variety of garment applications where an elastic is supplied in roll form and requires strength in a machine direction and elastic properties in a cross direction.Type: GrantFiled: October 4, 1996Date of Patent: March 23, 1999Assignee: Minnesota Mining and Manufacturing Co.Inventors: Jobst Tilman Jaeger, Alan J.
