Publication number: 20010049005Abstract: Antireflection coating on a substrate which is coated with a low refractive index layer having a specified refractive index which in turn is coated with a high refractive index layer having a higher refractive index than the low refractive index layer, is either characterized in that a roughened surface which scatters and reflects the incident light entered into the low refractive index layer in contact with the substrate is formed at the interface between the low refractive index layer and the substrate, or that a light-diffusing layer which scatters and reflects the incident light entered into the low refractive index layer in contact with the substrate is formed at the interface between the low refractive index layer and the substrate, or that a hard coating layer in contact with the low refractive index layer is formed by dispersing a light-diffusing material in the hard coating layer, which scatters and reflects the incident light entered into the low refractive index layer.Type: ApplicationFiled: December 18, 1997Publication date: December 6, 2001Inventors: TATSUO IKEGAYA, TOMIO HIRANO

Patent number: 6319593Abstract: A cleaning sheet including a base sheet and at least one surface layer of filaments placed on the base sheet is described. The filaments extend in one direction and each of the filaments extends over the whole length of the surface layer in the extension direction of the filaments. The base sheet and the surface layers are bonded to each other at a plurality of bonding lines intersecting the extension direction. The surface layer includes a plurality of filaments-holding regions, each of which includes at least one end of the bonding line other than the bonding lines forming the filaments-holding region. Accordingly, in the filaments-holding regions, differences-in-level for collecting dust are formed and gaps (pockets) for capturing the dust therein are exposed.Type: GrantFiled: March 18, 1999Date of Patent: November 20, 2001Assignee: Uni-Charm CorporationInventors: Yasuhiko Kenmochi, Yoshinori Tanaka, Yukiko Iida

Patent number: 6277470Abstract: A cube corner article having a structured surface of geometric structures, each geometric structure having a plurality of faces at least some of which are arranged as a cube corner element, is made by providing a first substrate having a plurality of grooves therein, replicating the first substrate in a second substrate, and forming a second plurality of grooves in the second substrate. Geometric structures in the second substrate are formed in part by replication of the first plurality of grooves and in part by the information of the second plurality of grooves.Type: GrantFiled: December 28, 1999Date of Patent: August 21, 2001Assignee: 3M Innovative Properties CompanyInventors: Kenneth L. Smith, Gerald M. Benson

Publication number: 20010004484Abstract: Films having a microreplicated topography are prepared from contacting a microembossed pattern to a layer of film. When an adhesion interface is established between the layer of film and a supporting substrate, the topography of the film surface controls the performance of the adhesion interface. Articles having microreplicated film surfaces are also disclosed that have an advantage of providing microchannels for fluid egress for an effective period of time. Multiple microembossed patterns produce microreplicated film surfaces having both microchannels for fluid egress and pegs for improved film properties.Type: ApplicationFiled: February 5, 2001Publication date: June 21, 2001Applicant: 3M Innovative Properties CompanyInventors: Frank T. Sher, Francis V. Loncar,

Patent number: 6238762Abstract: A covering sheet for applying to a selected surface in substantially fitted, covering relation consists of a flexible sheet of predetermined size and thickness, having a rectangular grid of lines to provide rectilinear yield lines (lines of weakness) extending in a first direction and in a second direction at right angles to the first direction, to enable tearing by hand along selected ones to the grid lines as a tear in a first direction, the sheet having individual perforations extending completely through its thickness, and located at the points of intersection of the axes of the lines of weakness. The perforations facilitate changes in the direction of a tear at a selected point of intersection, to extend the tear in the second direction, to achieve a desired size of sheet.Type: GrantFiled: September 3, 1999Date of Patent: May 29, 2001Assignee: Kittrich CorpInventors: Robert J. Friedland, Mark A. Calkins

Patent number: 6203886Abstract: A skew-toothed belt includes tension members, a tooth portion, and a back portion. The tooth portion and the back portion are located on opposite sides of an array of the tension members. The tooth portion is covered with a tooth cloth, which is arranged such that the weft thread extends substantially perpendicular to the tooth trace direction of each skewed tooth.Type: GrantFiled: March 18, 1999Date of Patent: March 20, 2001Assignee: Tsubakimoto Chain Co.Inventors: Hiroshi Kikuchi, Tooru Fujiwara, Mitsuo Kasahara, Yoshinori Itou

Patent number: 6149771Abstract: Process for manufacturing a press jacket of flexible material for a press device and a press jacket that is adapted to drain a material web in a press opening in a paper making machine. The process includes arranging at least one reinforcing fiber in a jacket material that forms the press jacket so that the reinforcing fibers are arranged to run substantially in a peripheral direction of the press jacket, forming grooves to run substantially in the peripheral direction in at least one surface of the press jacket, and orienting the arrangment of the at least one reinforcing fiber and the formation of the grooves relative to each other so that the at least one reinforcing fiber and the grooves do not run radially superposed in a same direction.Type: GrantFiled: May 28, 1998Date of Patent: November 21, 2000Assignee: Voith Sulzer Papiermaschinen GmbHInventor: Uwe Matuschczyk

Patent number: 6127020Abstract: A method of making a retroreflective marking material is provided, the method has the steps of: (a) providing an enclosed-lens retroreflective sheet having a top surface and a bottom surface and comprising a cover layer and a monolayer of retroreflective elements; (b) applying a conformance layer to the bottom surface of the retroreflective sheet; and (c) laminating a configuration member to the conformance layer thereby creating first portions and second portions in the sheet, the first portions being arranged in an upwardly contoured profile and the second portions being arranged in a lower, substantially planar position. A retroreflective article made by the method is also provided.Type: GrantFiled: May 7, 1999Date of Patent: October 3, 2000Assignee: 3M Innovative Properties CompanyInventors: Chester A.
