Patent number: 6790284Abstract: A coated film forming method is capable of readily forming a coated film of a thermoplastic material on a coated region of an inner peripheral surface of a cylinder. A nozzle, through which a molten paste of a thermoplastic material kept molten is discharged, is disposed toward an inner peripheral surface of a cylinder. The nozzle is moved along a rotational central line of the cylinder while rotating the cylinder and discharging the molten paste from the nozzle. Centrifugal force acting on the cylinder being rotated leads to spreading of the molten paste applied to the inner peripheral surface of the cylinder. Viscosity of the molten paste, a rotational speed of the cylinder and a speed of movement of the nozzle are set so as to keep the molten paste discharged from the nozzle from being scattered to a region other than the coated region.Type: GrantFiled: January 18, 2002Date of Patent: September 14, 2004Assignee: Illinois Tool Works Inc.Inventor: Yasuji Suzuki

Patent number: 6770142Abstract: An apparatus for monitoring an operation of a fluid dispensing gun dispensing a pattern of fluid onto a substrate moving with respect to the dispensing gun. The dispensing gun changes operating states in response to transition signals. A sensor is disposed adjacent the substrate and provides feedback signals in response to detecting edges of the fluid dispensed onto the substrate. A diagnostic monitor is responsive to the transition and feedback signals and automatically measures delays between occurrences of the transition signals and detecting corresponding edges of the fluid deposited onto the substrate resulting from the transition signals. The delays are measured by correlating the feedback signals to the transition signals. A method for measuring the delays is also described and claimed.Type: GrantFiled: October 29, 2001Date of Patent: August 3, 2004Assignee: Nordson CorporationInventor: Peter W. Estelle

Patent number: 6758908Abstract: A method and apparatus is provided for more efficient application of photoresist to a wafer surface. One aspect of the method comprises applying solvent to the wafer and spinning it to coat the entire wafer surface prior to the application of photoresist. This reduces surface tension on the wafer and reduces the amount of resist required to achieve a high quality film. The apparatus comprises adding a third solenoid and nozzle to the coating unit to accommodate the application of solvent to the center of the wafer surface. The method also describes incorporating a new solvent comprising diacetone alcohol, which is a low-pressure solvent, providing extended process latitudes and reduced material expenditures.Type: GrantFiled: August 29, 2001Date of Patent: July 6, 2004Assignee: Micron Technology, Inc.Inventor: John Whitman

Patent number: 6706118Abstract: A coating apparatus for applying a coating liquid to a printing substrate. The apparatus includes a rotatable first roll, and a rotatable second roll positioned adjacent to the first roll and defining with the first roll a first nip through which the printing substrate passes. The apparatus also has a metering device for applying a layer of coating liquid onto the second roll, which in turn transfers the coating liquid to the printing substrate. The apparatus further has a controller that communicates with at least the second roll, wherein the controller performs the steps of determining whether the idle time of the second roll is longer than a predetermined threshold, setting a pre-spin flag if the idle time of the second roll is longer than a predetermined threshold, and directing the second roll to perform a pre-spin upon the presence of the pre-spin flag.Type: GrantFiled: February 26, 2002Date of Patent: March 16, 2004Assignee: Lexmark International, Inc.Inventors: Philip Jerome Heink, Royden Thomas Kern, David Starling MacMillan, Johnny Ray Sears, Ronald Todd Sellers

Patent number: 6572705Abstract: The invention relates to a method and apparatus for growing a thin film onto a substrate, in which method a substrate placed in a reaction space (21) is subjected to alternately repeated surface reactions of at least two vapor-phase reactants for the purpose of forming a thin film. According to the method, said reactants are fed in the form of vapor-phase pulses repeatedly and alternately, each reactant separately from its own source, into said reaction space (21), and said vapor-phase reactants are brought to react with the surface of the substrate for the purpose of forming a solid-state thin film compound on said substrate. According to the invention, the gas volume of said reaction space is evacuated by means of a vacuum pump essentially totally between two successive vapor-phase reactant pulses.Type: GrantFiled: January 14, 2000Date of Patent: June 3, 2003Assignee: ASM America, Inc.Inventors: Tuomo Suntola, Sven Lindfors

Patent number: 6471837Abstract: A vacuum coating installation has at least a central distribution station which can be evacuated and has a transport arrangement driven in a controlled manner essentially along a plane, for the material to be treated. One operating station for the distribution station as well as at least two processing stations for the material to be treated are provided. The three or more stations communicate by way of operating openings with the distribution station, through which openings the material to be treated can be transported from one station into the other by the transport arrangement for the material to be treated. The material to be treated is formed by individual workpiece holders of the installation, each having a plurality of workpiece supports.Type: GrantFiled: March 29, 2000Date of Patent: October 29, 2002Assignee: Unaxis Trading AGInventors: Michael Hans, Martin Zaech

Patent number: 6051070Abstract: An apparatus for applying a material to a substrate. A material application station includes a shutter assembly having at least one horizontally extending blade which is rapidly displaceable from a closed configuration in which an outlet path of the shutter assembly is obstructed to an open configuration in which the outlet path is open. While the blade of the shutter assembly is in the closed configuration, a coating material is applied to a first predetermined area on an upper surface of the shutter assembly. A substrate is located beneath the shutter assembly in the outlet path. The blade of the shutter assembly is rapidly opened so that the coating material falls onto the substrate over a second predetermined area on an upper surface of the substrate. The second predetermined area is substantially equal to the first predetermined area. The resulting deposit is of a controlled diameter. A rapid opening of the blade allows the deposit to fall a short distance onto a substrate such as a pizza base.Type: GrantFiled: November 12, 1998Date of Patent: April 18, 2000Assignee: Ishida Co., Ltd.Inventor: Adrian M.
