Using this resist 201 as a mask, powders or particles are sprayed onto the piezoelectric device 43 for removing the portion of the piezoelectric device 43 not carrying the resist 201 to form the piezoelectric device 35 of a desired shape at a pre-set position.Type: GrantFiled: February 26, 1998Date of Patent: June 11, 2002Assignee: Sony CorporationInventor: Koichiro Kishima

Patent number: 6372164Abstract: A visual effect, such as a granite-look, is produced in a thermoplastic product by directly applying a sufficient amount of at least one color-containing thermoplastic resin system to the surface of an extruded sheet of a thermoplastic resin. The color-containing thermoplastic resin system is applied onto the extruded sheet after it emerges from the die and prior to it entering the rollstack.Type: GrantFiled: May 26, 1999Date of Patent: April 16, 2002Assignee: BASF CorporationInventors: James H. Bennett, Steve Wasson, Gary Kogowski

Publication number: 20010048174Abstract: A thermoplastic shaped resin article may include, for example, a shaped base material and a thermoplastic resin sheet. A discontinuous metal film may be disposed on one surface of the resin sheet. The base material may be adhered to the resin sheet so that the metal film faces the base material. As a result, shaped resin articles may be prepared that have a metallic appearance and transmit visible light.Type: ApplicationFiled: March 19, 2001Publication date: December 6, 2001Inventors: Ryuichi Yamada, Miyuki Ogasawara, Masahito Hoshino, Yasuyuki Ohara

Patent number: 6258201Abstract: The present invention provides a method of making sheet articles, for example, abrasive articles, retroreflective articles (such as traffic signs), pavement marking articles, or traction or non-skid articles. The method includes passing particles through a thermal sprayer to heat the particles and impinging the heated particles into a polymeric sheet so that the particles are at least partially embedded in the polymeric sheet. Preferably, the polymeric sheet is heated before impingement of the heated particles. One preferred method of softening the sheet is by a thermal sprayer that is used to heat the particles. A preferred thermal sprayer is a flame sprayer having a nozzle for emitting a flame, where the nozzle has a cross-web width and a downweb thickness, the width being substantially greater than the thickness.Type: GrantFiled: April 23, 1999Date of Patent: July 10, 2001Assignee: 3M Innovative Properties CompanyInventor: John E.

Publication number: 20010006712Abstract: A hose of impermeability has a wall corrugated along at least a part of its length, and formed by an inner thin resin layer, a laminated layer including a metal film, or a layer formed by a metal film, and an outer thin resin layer. It has a very high fluid impermeability owing to its wall layer including or formed by a metal film, and is also very flexible, capable of absorbing vibration, light in weight and strong. A tubular inner thin resin layer is formed by extrusion as the innermost layer of a multi-layered hose wall, and a laminated tape including a metal film, or simply a metal film is spirally wound or longitudinally lapped about the inner resin layer. An outer thin resin layer is formed about a layer formed by the laminated tape, or metal film, and the whole is at least partly corrugated. Alternatively, corrugation is done before an outer thin resin layer is formed by electrostatic powder coating.Type: ApplicationFiled: December 20, 2000Publication date: July 5, 2001Inventors: Motoshige Hibino, Kazutaka Katayama, Ayumu Ikemoto, Hidehito Ikeda, Hiroaki Ito

Patent number: 6238732Abstract: This invention relates to a hot melt adhesive composition in pellet form. The hot melt adhesive composition is pressure sensitive, having a storage modulus, G′, at 25° C., of less than about 5×106 dynes/cm2. The pellets are coated with a pelletizing aid on the surface at a concentration preferably ranging from about 1 wt-% to about 30 wt-%. The pelletizing aid is a hot melt adhesive component or a material which does not substantially adversely affect the adhesive properties.Type: GrantFiled: May 31, 2000Date of Patent: May 29, 2001Assignee: H. B. Fuller Licensing & Financing Inc.Inventors: Janelle C. Cameron, Carolyn A. Fischer, Nicholas C. Lehman, Jeffrey S. Lindquist, Christopher E. Olson, Steve A. Fox

Patent number: 6228492Abstract: A process for preparing fibers containing intrinsically conductive polymers comprises extruding two or more filaments, applying a coating formulation containing a salt of an intrinsically conductive polymer to at least one of the filaments to form a coated filament, combining the filaments to form a filament bundle, and processing the bundle into a fiber. A filament coated with an intrinsically conductive polymer and a fiber comprising at least one coated filament are also provided which are useful in preparing textiles and other materials which exhibit conductivity.Type: GrantFiled: September 23, 1997Date of Patent: May 8, 2001Assignee: Zipperling Kessler & Co.

Patent number: 6217815Abstract: Prophylactic devices are made in an inert atmosphere by cooling mandrels on which the devices are to be deposited, dipping the mandrels into a polymeric material in a solvent/carrier and a mold release agent, rotating the mandrels during and after the dipping, and evaporating the solvent after dipping. The apparatus includes an air lock between a section in which these functions are performed and a section located in an air atmosphere for removing the devices from the mandrels, followed by cleaning the mandrels for use in a subsequent production run for making devices.Type: GrantFiled: June 10, 1998Date of Patent: April 17, 2001Assignee: Carter-Wallace, Inc.Inventor: Frederick P.

Patent number: 6200404Abstract: Compositions and methods for manufacturing sheets having a starch-bound matrix reinforced with fibers and optionally including an inorganic mineral filler. Suitable mixtures for forming the sheets are prepared by mixing together water, unmodified and ungelatinized starch granules, an auxiliary water-dispersible organic polymer, fibers, and optionally an inorganic mineral filler in the correct proportions to form a sheet having desired properties. The mixtures are formed into sheets by passing them between one or more sets of heated rollers to form green sheets. The heated rollers cause the auxiliary polymer to form a skin on the outer surfaces of the sheet that prevents the starch granules from causing the sheet to adhere to the rollers upon gelation of the starch. The green sheets are passed between heated rollers to gelatinize the starch granules, and then to dry the sheet by removing a substantial portion of the water by evaporation.Type: GrantFiled: November 24, 1998Date of Patent: March 13, 2001Assignee: E. Khashoggi Industries, LLCInventors: Per Just Andersen, Shaode Ong, Bruce J. Christensen, Simon K. Hodson

Patent number: RE37875Abstract: Solid objects are formed in an imagewise layering process in which components of a dispersion are homogenized to form an alloy. Imagewise exposure of the layers to radiation to form an alloy permits separation of the exposed, homogenized regions from non-exposed, non-homogenized regions. As each layer is formed and imagewise homogenized, contiguous layer regions are bonded together to form a homogenized, three-dimensional object which may be separated from surrounding dispersion.Type: GrantFiled: November 13, 2000Date of Patent: October 15, 2002Inventor: John A.
