Patent number: 6419335Abstract: An electronic drive system applies a drive signal to an electrostatically actuated device such that a resulting electric field has a constant force. In various exemplary embodiments, the electronic drive system applies a drive signal to an electrostatically actuated fluid ejector that has a piston and a faceplate including a nozzle hole. A dielectric fluid to be ejected is supplied between the piston and the faceplate. The drive signal is applied to one of the piston and the faceplate. The drive signal generates an electric field across the fluid between the piston and the faceplate. The electric field causes the piston to be electrostatically attracted towards the faceplate so that a jet or drop of fluid is ejected through the nozzle hole of the faceplate. According to exemplary embodiments, the drive signal is from a constant current source or is reduced over the course of its lifetime.Type: GrantFiled: November 24, 2000Date of Patent: July 16, 2002Assignee: Xerox CorporationInventors: Arthur M.

Patent number: 6416169Abstract: A piston structure is movably mounted within a fluid chamber. Movement of the piston structure towards a faceplate causes a portion of the fluid between the piston and the faceplate to be forced out of the nozzle hole in the faceplate, forming a drop or jet of the fluid. Viscous forces that are generated by the flow of fluid along a working surface of the piston structure toward and away from the nozzle hole generate a force that resists the movement of the piston structure. This resistance force tends to slow the piston motion, and prevents the piston from contacting the faceplate. In various embodiments, the fluid chamber is defined by a cylinder structure. The piston structure moves within the cylinder structure. The cylinder structure and the faceplate define the fluid chamber. The cylinder structure and the piston structure are designed to cooperate so that the movement of the piston structure within the cylinder structure ejects fluid according to various design criteria.Type: GrantFiled: November 24, 2000Date of Patent: July 9, 2002Assignee: Xerox CorporationInventors: Arthur M. Gooray, George J. Roller, Joseph M. Crowley, Paul C. Galambos, Frank J. Peter, Kevin R. Zavadil, Richard C. Givler

Patent number: 6409311Abstract: A bi-directional fluid ejector according to the systems and methods of this invention operates on the principle of electrostatic attraction. In various exemplary embodiments, the fluid ejector includes a sealed dual diaphragm arrangement, an electrode arrangement that is parallel and opposite to the sealed diaphragms, and a structure which contains the fluid to be ejected. A diaphragm chamber containing a relatively incompressible fluid is situated behind, and is sealed by, the diaphragms. At least one nozzle hole is formed in a faceplate of the ejector over one of the diaphragms. A drive signal is applied to at least one electrode of the electrode arrangement to generate an electrostatic field between the electrode and a first one of the diaphragms. The first diaphragm is attracted towards the electrode by an electrostatic force into a deformed shape due to the electrostatic field. Upon deforming, pressure is transmitted to a second one of the sealed diaphragms.Type: GrantFiled: November 24, 2000Date of Patent: June 25, 2002Assignee: Xerox CorporationInventors: Arthur M.

Patent number: 6367915Abstract: An electrostatic microelectromechanical system (MEMS) based fluid ejector comprises a movable piston structure and a stationary faceplate. A fluid chamber is defined between the piston structure and a substrate. The piston structure 110 may be resiliently mounted on the substrate by one or more spring elements. A fluid to be ejected is supplied in the fluid chamber from a fluid reservoir through a fluid refill hole formed in the substrate. The faceplate includes a nozzle hole through which a fluid jet or drop is ejected. In various exemplary embodiments, the piston structure moves towards the faceplate by electrostatic attraction between the piston structure and the faceplate. As a result of the movement of the piston structure, a portion of the fluid between the piston structure and the faceplate is forced out of the nozzle hole, forming a jet or drop of the fluid.Type: GrantFiled: November 28, 2000Date of Patent: April 9, 2002Assignee: Xerox CorporationInventors: Arthur M.

Patent number: 6350015Abstract: The systems and methods of the present invention operate by magnetically driving a fluid ejector. In various exemplary embodiments, a primary coil and a secondary coil are situated in the ejector. The ejector has a movable piston usable to eject fluid through a nozzle hole. The piston may be resiliently mounted and biased to an at-rest position. A drive signal is applied to cause current to flow in the primary coil. The current flow generates a magnetic field that induces a current in the secondary coil. Either the primary coil or the secondary coil or associated with the piston and the other is associated with a fixed structure of the ejector. As a result, a magnetic force is generated that pushes the piston either toward a faceplate so that a drop of fluid is ejected through the nozzle hole in the faceplate or away from the faceplate so that fluid fills in a fluid chamber between the piston and the faceplate.Type: GrantFiled: November 24, 2000Date of Patent: February 26, 2002Assignee: Xerox CorporationInventors: Arthur M.

Patent number: 5712672Abstract: A transport system for transporting a recording sheet having liquid ink deposited thereon through a dryer for drying the liquid ink having an input portion and an output portion. The transport system includes a transport belt disposed between the input portion and the output portion for transporting the recording sheet through the dryer. A negative pressure member is located beneath the belt and defines a negative pressure chamber. The pressure member decreases the pressure within the pressure member so that a non-uniform negative pressure is applied to the recording sheet during transport through the dryer. A directing member located within a plenum directs differing negative pressures within the plenum such that negative pressures decrease in amplitude along the transport direction. The application of a negative pressure within the plenum also tends to reduce or remove evaporated liquid driven from the inks during drying.Type: GrantFiled: April 3, 1995Date of Patent: January 27, 1998Assignee: Xerox CorporationInventors: Arthur M.
