The cryogenic and plasma processes can be performed sequentially or simultaneously.Type: GrantFiled: July 29, 2002Date of Patent: July 20, 2004Assignee: NanoClean Technologies, Inc.Inventors: Mohamed Boumerzoug, Adel George Tannous, Khalid Makhamreh

Patent number: 6673160Abstract: In order that sensitive structures of inkjet printing mechanisms be cleaned without damaging these structures, a cleaning sheet and a process of using the sheet has been created. Debris and dried ink is removed from print cartridges and their carriage using a cleaning sheet having two strips of material spaced with a napped surface disposed longitudinally between the side edges and spaced apart from each other. By controlling the distance the strips are spaced from the sheet feed edge of the cleaning sheet, the print cartridges can be placed adjacent the strips for scrubbing against the strips without resulting in a media jam in the printer due to the increased thickness of the cleaning sheet.Type: GrantFiled: February 5, 2001Date of Patent: January 6, 2004Assignee: Hewlett-Packard Development Company, L.P.Inventors: Ralph L Stathem, John R. Carnes, Kevin Almen, Babak Honaryar, Kris M. English

Patent number: 6663719Abstract: A cleaning system and a cleaning method is provided with a cleaning medium comprising a magnetic substance and a magnetic field generating device for applying a magnetic force to the magnetic substance in the cleaning medium so that the magnetic substance and the area to be cleaned are rubbed together. The area to be cleaned is cleaned by the rubbing action of the cleaning medium. The interior of the cleaned object not reachable by hands or instruments can be easily cleaned with this device. The cleaning medium, made of a magnetic substance, is guided into the interior of the cleaned object. The magnetic field generating device generates a magnetic field in the cleaning medium and thereby applies a force to the magnetic substance. By rubbing the magnetic substance on the inner wall surface of the area to be clean, the object can be cleaned efficiently.Type: GrantFiled: March 26, 2001Date of Patent: December 16, 2003Assignee: Ricoh Company, Ltd.Inventors: Kenichi Shinozaki, Tohru Maruyama

Publication number: 20030205244Abstract: A strip with an exterior sticky surface is judiciously selected for its ability to entrap dust and other loose debris without interfering with the operation of moving parts contacted thereby. The strip is attached to the sides of a magnetic tape cartridge, with the sticky surface facing outward, in places contacted by rollers and/or belts during the process of handling the cartridge in an automated system. Thus, any loose debris in the rollers or belts is retained by the tacky surface of the strip as the cartridge passes through the rollers and belts of the robotic system. The strips of the invention may be removably adhered to the data cartridge, or may be permanently attached. In a particular embodiment of the invention, the strips may be incorporated into a cleaner cartridge for the periodic maintenance of loading equipment.Type: ApplicationFiled: June 3, 2003Publication date: November 6, 2003Inventor: Lee Curtis Randall

Patent number: 6638425Abstract: A magnetic filter removes magnetic particles from fluid communicated through the filter. The filter includes elongated, circumferentially spaced magnetic elements which capture magnetic particles entrained in the fluid. The magnetic elements must be cleaned periodically to remove the particles from the elements by moving a scraper plate from one end of the housing to the other. At the end of travel of the scraper plate, the particles are scraped upon non-magnetic end portions (which may contain residual magnetism) of the magnetic elements, from which they are flushed by fluid communicated through the inlet port out through other ports provided on the housing.Type: GrantFiled: March 28, 2001Date of Patent: October 28, 2003Assignee: Filter Specialists, Inc.Inventor: Gunther E. Asterlin

Patent number: 6638363Abstract: A cleaning apparatus for cleaning solder paste off the bottom side of a printed circuit board stencil includes a container of cleaning solution therein and a blade holder that is movable between a wiping position and the container of cleaning solution. A wiping blade is mounted in the blade holder. The blade holder, with the blade mounted thereon, is reciprocated back and forth when in communication with a stencil to be cleaned. The blade is moved from the wiping position in communication with the stencil into the cleaning solution in the container. A pneumatic piston and rotary actuator provides controlled movement of the wiping blade. The wiping blade may be vibrated during wiping to improve removal of solder paste from the stencil and the cleaning solution may be ultrasonically vibrated to improve removal of solder paste from the wiping blade. The wiping blade may also be pulsed into a sponge to remove excess cleaning solution prior to the next cleaning cycle.Type: GrantFiled: October 17, 2002Date of Patent: October 28, 2003Inventor: Gunter Erdmann
