Patent number: 6500568Abstract: Described is an article comprising a biaxially textured metal substrate and a layer of palladium deposited on at least one major surface of the metal substrate; wherein the palladium layer has desired in-plane and out-of-plane crystallographic orientations, which allow subsequent layers that are applied on the article to also have the desired orientations.Type: GrantFiled: June 6, 2001Date of Patent: December 31, 2002Assignee: 3M Innovative Properties CompanyInventor: William B. Robbins

Patent number: 6416188Abstract: Exposed lens retroreflective appliques incorporate a monolayer of beads and a dielectric mirror proximate the beads. A pigmented or otherwise colored bead bond layer in which the beads are partially embedded is visible through the dielectric mirror, giving the article a highly colored daytime appearance. The appliques exhibit an initial reflectivity. By appropriate materials selection, the appliques can be made to retain at least 75%, and in most instances at least 90%, of the initial reflectivity if subjected to fifty home laundering cycles. In one case the dielectric mirror includes zinc sulfide as a relatively high refractive index material and calcium fluoride as a relatively low refractive index material. In another case the dielectric mirror includes zinc sulfide as the relatively high refractive index material and silicon dioxide as the relatively low refractive index material.Type: GrantFiled: April 11, 2000Date of Patent: July 9, 2002Assignee: 3M Innovative Properties CompanyInventors: Jeanine M. Shusta, Norman D. Ligtenberg, William B. Robbins

Patent number: 5767808Abstract: A microstrip patch antenna has a first conductive layer adjacent a dielectric substrate. The first conductive layer has a thickness of less than one skin depth of the material of the first conductive layer. A second conductive layer acts as the ground plane for the first conductive layer and a feed network feeds the radiating patch of the first conductive layer.Type: GrantFiled: January 13, 1995Date of Patent: June 16, 1998Assignee: Minnesota Mining and Manufacturing CompanyInventors: William B. Robbins, Timothy S. Skogland

Patent number: 5660892Abstract: A metallic film is disclosed. The film has a layer of an organic polymer substrate having an sulfur-reactive surface, to which is adhered a vapor deposited metallic layer. Optionally, a metallic halide layer is formed on the metallic layer to provide depolarizing capacity for the metallic film. Methods of making and using the metallic film are disclosed. Biomedical electrodes, including radiolucent defibrillation electrodes, window films, optical reflectors, and flexible electronic circuits are articles which can use the metallic film as a component.Type: GrantFiled: December 8, 1995Date of Patent: August 26, 1997Assignee: Minnesota Mining and Manufacturing CompanyInventors: William B. Robbins, Leif Christensen, Richard E. Volkmann, Rafael M. Yasis, Laura M. Aguilar

Patent number: 5637882Abstract: A detector plate for use in a radiation imaging system includes a first conductive layer, a dielectric layer, a photoconductive layer and a second conductive layer, arranged as a stack in that order. The first conductive layer and the dielectric layer are substantially transparent to radiation energy so as to allow the energy to pass therethrough to be received by the photoconductive layer. The first conductive layer has a periphery defined by a first edge and the dielectric layer has a periphery defined by a second edge, wherein the first edge is offset inward of the second edge defining a margin between the first and second edges. In use, this margin helps inhibit electrical arcing from the first conductive layer to the second conductive layer when a high voltage is applied between these two layers.Type: GrantFiled: December 1, 1995Date of Patent: June 10, 1997Assignee: Minnesota Mining and Manufacturing CompanyInventors: Ranjith Divigalpitiya, Bimsara W. Disanayaka, William B. Robbins, Earl L. Cook, Keith K. McLaughlin

Patent number: 4539572Abstract: An optical recording medium containing a light-absorbing film of refractory material less than 60 nm thick and selected from carbides of Al, Hf, Nb, Ta, Ti, V, W, and Zr and alloys herebetween, whereupon localized heating of the light-absorbing film enables information storage in the form of localized features in the heated areas which can subsequently be optically detected and can be used as a master information record for replication purposes.Type: GrantFiled: February 15, 1983Date of Patent: September 3, 1985Assignee: Minnesota Mining and Manufacturing CompanyInventors: William B. Robbins, Richard F. Willson, Robert P. Freese

Patent number: 4470053Abstract: An optical recording medium containing a light-absorbing film of a refractary material selected from the group, consisting of boron, borides of carbon, silicon, hafnium, niobium, tantalum, titanium, tugsten, and zirconium, nitrides of boron, hafnium, tantalum and titanium, oxides of hafnium, cerium, magnesium and thorium, and silicides of niobium, tantalum, titanium, and tungsten less than 60 nm thick and which is sufficiently plastic to allow deformation upon localized heating by exposure to a focused laser beam, whereupon the localized heating of the light absorbing film enables information storage in the form of localized protuberances in the heated areas which can be used as a master for replication purposes.Type: GrantFiled: January 24, 1983Date of Patent: September 4, 1984Assignee: Minnesota Mining and Manufacturing CompanyInventors: Kent N. Maffitt, William B. Robbins, Richard F. Willson
