The lithographic apparatus comprising an original master on which a pattern is formed within a two-dimensional plane, a slit for filling a medium in the pattern, a medium sump for feeding the medium, a pressure regulating mechanism for adjusting the pressure of the medium filled in the slit, and a lithographic substrate. With this apparatus, the pattern can be batch-transferred, thereby making it possible to easily manufacture electronic parts.Type: GrantFiled: September 24, 2001Date of Patent: October 21, 2003Assignee: Hitachi, Ltd.Inventors: Akihiro Miyauchi, Lee Chahn, Mitsuru Hasegawa, Mitsuo Hayashibara, Hiroshi Sasaki

Patent number: 6599436Abstract: A method is disclosed to form external interconnections to a microfluidic device for coupling of a fluid or light or both into a microchannel of the device. This method can be used to form optical or fluidic interconnections to microchannels previously formed on a substrate, or to form both the interconnections and microchannels during the same process steps. The optical and fluidic interconnections are formed parallel to the plane of the substrate, and are fluid tight.Type: GrantFiled: December 6, 2001Date of Patent: July 29, 2003Assignee: Sandia CorporationInventors: Carolyn M. Matzke, Carol I. H. Ashby, Leonardo Griego

Patent number: 6540153Abstract: The invention provides exemplary methods and apparatus for dispensing liquids as an atomized spray. In one particularly preferably method, a liquid is dispensed as an atomized spray from a vibratable member having a front surface and a rear surface, with the member having at least one tapered hole between the surfaces for dispensing the liquid. The tapered hole has a larger cross-sectional area at the rear surface than at the front surface. The liquid is delivered from a supply container to the rear surface of the vibratable member in an amount sufficient to cover the hole with liquid. The vibratable member is then vibrated to dispense at least a portion of the liquid through the hole and from the front surface. Additional liquid is delivered from the supply container and to the rear surface in volumes that are substantially equal to the volumes dispensed.Type: GrantFiled: May 27, 1999Date of Patent: April 1, 2003Assignee: Aerogen, Inc.Inventor: Yehuda Ivri

Patent number: 6529220Abstract: An image recording liquid obtained by changing a mixing proportion of a plurality of recording liquids based on an image signal is transferred as a continuous flow to an image receiving medium to form an image thereon. To the image receiving medium, the image recording liquid is transferred in an image forming width, and a dummy liquid for forming substantially no image is transferred to the outside of the image forming width. Both edges of the image recording area are prevented from being raised or thickened on the image receiving medium or from spreading over in the width direction. The image density is prevented from increasing or decreasing on the edge of the image, the stream line of the image recording liquid can be prevented from being distorted, and the image quality can be enhanced. In another mode, the dummy liquid continues to a fore end and/or a rear end of the image forming area and is transferred to the image receiving medium.Type: GrantFiled: September 6, 2000Date of Patent: March 4, 2003Assignee: Fuji Photo Film Co., Ltd.Inventor: Nobuo Matsumoto

Patent number: 6493009Abstract: An image forming apparatus, applicable to copying machines, facsimile apparatuses and printers, controls pixel positions with high precision. An image of color material is formed on the surface of an image holding drum. The surface of the image holding drum divides into a number of pixel areas, and each pixel area has an adhesive-force change portion smaller than the pixel area, where adhesive force to color material changes by a predetermined stimulus. An image-signal input unit forms an image by distribution of adhesive force to the color material on the surface of the image holding drum by inputting a stimulus corresponding to an image signal into the image holding drum. A color material supply unit supplies color material particles to the surface of the image holding drum.Type: GrantFiled: November 2, 1998Date of Patent: December 10, 2002Assignee: Fuji Xerox Co., Ltd.Inventors: Hirokazu Mukai, Mamoru Kido, Nobuyuki Nakayama

Patent number: 6486901Abstract: A method for microfluidic printing comprising pumping and mixing colored inks which comprise a mixture of colorants, fluids, and gel-forming or gel-initiating ingredients to form ink pixels and to transfer such ink pixels to a receiver transferring position; and transferring the ink pixels to a reflective receiver which contains gel-forming or gel-initiating ingredients so that the ingredients in the transferred ink pixels and in the receiver react to form a gel and the viscosity of the transferred ink rapidly increases to limit the flow of ink pixels whereby such ink pixels are fixed to the receiver and overprinting of colors is minimized.Type: GrantFiled: August 29, 1997Date of Patent: November 26, 2002Assignee: Eastman Kodak CompanyInventors: Charles D. DeBoer, Werner Fassler, Xin Wen

Patent number: 6454482Abstract: A pen includes an electronically controllable marking device, for marking a visible path onto a surface. The device includes a memory for storing sets of values of attributes of the path. The pen also has a selection mode, in which the pen is caused to cycle though the stored sets of attribute values by the user sequentially marking separate paths, with a different set of attribute values applied each path compared to the preceding path.Type: GrantFiled: October 20, 2000Date of Patent: September 24, 2002Assignee: Silverbrook Research Pty LtdInventors: Kia Silverbrook, Paul Lapstun, Tobin Allen King

Publication number: 20020126162Abstract: A printer, a print head, and a print head manufacturing method in which satisfactory precision can be obtained by simple processes are provided. Projecting objects having a predetermined shape are formed on a substrate, and a setting resin is applied on the substrate and is set. Then, the projecting objects are removed so that ink cells and nozzles are formed. The thickness of the setting resin is determined such that tip portions of the projecting objects project from the setting resin and ink cells can be formed.Type: ApplicationFiled: November 7, 2001Publication date: September 12, 2002Inventors: Manabu Tomita, Koichi Igarashi
