Patent number: 5920013Abstract: A protective coating is utilized to protect the silicon during a wet chemical etch step in the process of making a micromachine, thereby preventing the formation of etched holes or pits in the micromachine. In another embodiment, silicon sacrificial pedestals are used to eliminate or greatly reduces the electrical potential difference between metal on the glass substrate and the silicon, thereby eliminating arcing and the resulting damage to silicon and metal. These pedestals may be removed after the anodic bond.Type: GrantFiled: February 7, 1997Date of Patent: July 6, 1999Assignee: Ford Motor CompanyInventors: William John Boardman, John Crumlin, John Ralph Lindsey, Paul Thomas Carson, Judd Steven Carper, John Ames, Paul Elwin Stevenson

Patent number: 5910535Abstract: A modified coating composition including a water based coating and a silicone component comprising 2 to 12 weight percent of the composition. The water based coating is preferably an acrylic latex paint. Preferably a filler is also included in the composition. The coating provides a sacrificial characteristic wherein layers may be removed with a stain or mark, leaving the coated surface looking new, using no more than soap and water.Type: GrantFiled: May 3, 1996Date of Patent: June 8, 1999Assignee: Decora, IncorporatedInventor: John Ralph Smith

Patent number: 5814402Abstract: A pressure sensitive dry transfer article comprising a backing film, a release coating applied to a first face of the backing film, a continuous film of brittle polymeric compound applied to the release coating, and a pigmented pressure sensitive adhesive coating applied in imagewise fashion to said polymeric film to form a graphic pattern. On application of the article to the bonding substrate by pressure applied to the areas defined by the graphic pattern, the pigmented pressure sensitive adhesive is transferred to the bonding substrate and, after peeling the article away from the bonding substrate, the polymeric film fractures along the borders defining the graphic pattern such that the polymeric film in union with the graphic pattern is transferred with the pressure sensitive adhesive to the bonding substrate and the polymeric film not in union with the graphic pattern remains with the release coating.Type: GrantFiled: April 20, 1993Date of Patent: September 29, 1998Assignee: Decora IncorporatedInventor: John Ralph Smith

Patent number: 5768064Abstract: The improved disk drive system has an improved actuator arm assembly where the arms are independently and individually insertable and removable from the actuator member. Furthermore, each arm is individually self-locked into the actuator member without the need for external retaining means such as screws, springs, and rings. Since the arms are individually insertable/removable, the arms can be made very thin thereby allowing easy attachment of the head suspension assembly to the arm without the need for swaging, bonding, welding or screw-in. Since the arms can be made very thin, that provides substantial reduction in disk to disk spacing and therefore, substantial reduction in the overall height of a disk drive system.Type: GrantFiled: June 27, 1997Date of Patent: June 16, 1998Assignee: International Business Machines CorporationInventors: Holger Johan Baasch, Lowell James Berg, Alexander Gredinberg, Peter Maurice Herman, Jerry Lee Neubauer, John Ralph Reidenbach, Oscar Jaime Ruiz, Victor Wing Chun Shum

Patent number: 5740691Abstract: A press is described for prehemming and final hemming the internal periphery of an aperture in sheet material received on an anvil (10) on which the sheet material (12) is held down so that the upturned edge (14) of the aperture which is to be hemmed is substantially in alignment with the edge of the opening in the anvil (10). A composite hemming tool (40, 42) is provided adapted to perform prehemming and final hemming and carried b a tool carrier (36, 38). Drive means (24, 26) protrudes up from the press through the opening in the anvil so that a lower inclined leading edge (44, 46) of the tool substantially registers with the upturned edge (14) to be hemmed. The drive means operates so as to force the tool first of all towards the edge so as to bend the upturned edge over until it is bent through substantially 90 degrees from its upstanding position and thereafter to move in a generally downward direction so as to compress the downturned ege. A method of hemming is also described based on this machine.Type: GrantFiled: July 29, 1996Date of Patent: April 21, 1998Assignee: Western Atlas U.K. LimitedInventors: Josef Kovarovic, John Ralph Kowalewsky, Gerrit Wesley Sloat
