Patent number: 10147449Abstract: Various embodiments concern a method of attaching a microactuator to a flexure, depositing a wet mass of structural adhesive on the flexure, mounting the microactuator on the wet mass of structural adhesive, partially curing the mass of structural adhesive through a first application of curing energy, and depositing a mass of conductive adhesive on the flexure. The mass of conductive adhesive is deposited in contact with the mass of structural adhesive. The state of partial curing of the structural adhesive prevents the conductive adhesive from wicking between the flexure and the underside of the microactuator and displacing the structural adhesive which may otherwise result in shorting to a stainless steel layer of the flexure. The method further comprises fully curing the mass of structural adhesive and the conductive adhesive through a second application of curing energy.Type: GrantFiled: November 20, 2017Date of Patent: December 4, 2018Assignee: Hutchinson Technology IncorporatedInventors: Scott J. Cray, John L. Schumann, Trent A. Johnson, Luke E. Rose

Patent number: 9443547Abstract: The present disclosure relates to methods and a related systems and tools for dispensing an adhesive piece having damping qualities onto a component of a hard disk drive suspension. The adhesive piece can be commercially available layered strip sold as an adhesive layer having a first and a second liner adhered to each side. An exemplary method can cut an adhesive piece, separate the adhesive piece from a secondary liner, adhere the adhesive piece onto a component of a hard disk drive suspension, separate a primary liner from the adhesive piece, and dispose of the primary liner using a conventional gantry system. The method can be performed using a two-step operation of the gantry system.Type: GrantFiled: August 25, 2014Date of Patent: September 13, 2016Assignee: Hutchinson Technology IncorporatedInventors: Bryan J. Scheele, Neal T. Eidenschink, John L. Schumann, Trent A. Johnson, Daniel W. Scheele, Cameron T. Hempel, Scott J. Cray, Kenneth L. Bolster

Patent number: 8051553Abstract: Apparatus for adjusting the static attitude of a head suspension having a gimbal with at least one gimbal arm. One embodiment of the invention includes a pair of first contacting members contacting a first side of the gimbal arm at a pair of spaced apart locations, and a second contacting member contacting a second side of the gimbal arm at an intermediate location between the spaced apart locations. The first and second contacting members move together relative to each other, plastically deforming the gimbal arm by the relative movement between the second and first contacting members while the spaced apart location between the first contacting members is maintained during the plastic deformation such that at least one of a pitch and roll parameter of the gimbal is adjusted to a desired amount.Type: GrantFiled: December 14, 2007Date of Patent: November 8, 2011Assignee: Hutchinson Technology IncorporatedInventors: Thomas H. Wick, Mark S. Hedeen, Jeremy J. Stroschein, John L. Schumann, Justin M. Eggert

Publication number: 20090208173Abstract: A fiber cable assembly includes a cable formed from a bundle of fiber optic strands, a buffer encasing the bundle, and a terminator clamp coupled to an end of the cable over the buffer. The terminator clamp includes a first clamp portion and a second clamp portion. The first and second clamp portions each have an engaging surface for engaging the other of the first clamp portion and the second clamp portion. A channel is formed between the first clamp portion and the second clamp portion for receiving an end of the cable. The channel has a cross-sectional area that is less than a cross-sectional area of the cable. The end of the cable can be inserted into the first clamp portion and the second clamp portion can be secured to the first clamp portion to secure the clamp terminator to the cable. The cable is compressed within the channel to a reduced cross-sectional area.Type: ApplicationFiled: February 20, 2008Publication date: August 20, 2009Inventors: John L. Schumann, Alan D. Maki, Bryan J. Scheele, Robert A. Johnson

Patent number: 4283205Abstract: An inlet flue system for conducting particulate-containing gases to the inlet nozzles of a multiplicity of electrostatic precipitator chambers comprises an elongated plenum located generally above the nozzles. The plenum is substantially entirely open at the bottom, and the inlet ends of the perimeter walls of branch ducts leading from the open bottom define a series of outlet openings from the plenum. The open bottom construction leaves the plenum substantially free of upwardly facing surfaces where particulates can settle.Type: GrantFiled: April 6, 1979Date of Patent: August 11, 1981Inventor: John L. Schumann
