Patent number: 5665444Abstract: A tube-shaped film, made of fluorine resin, has a fold-free, smooth, and uniform inner peripheral surface formed thereon by a surface treatment. An apparatus for treating the inner peripheral surface of the tube-shaped film includes a holding device for holding the tube-shaped film on the inner peripheral surface of a cylindrical body with a cylindrical configuration of the tube-shaped film maintained. A treatment device is inserted into the cylindrical body to treat the inner peripheral surface of the tube-shaped film held on the inner peripheral surface of the cylindrical body. The holding device and the treatment device make a uniform linear motion relative to each other and a uniform rotary motion relative to each other.Type: GrantFiled: August 13, 1996Date of Patent: September 9, 1997Assignee: Kurashiki Boseki Kabushiki KaishaInventors: Yosuke Eguchi, Atsuki Wada, Tomohiro Nagase, Yoshiro Hirajima

Patent number: 5637149Abstract: Solder is applied to a circuit structure 7 by dipping the structure into a bath 1 of molten solder 3, the molten solder having a layer of oil 5 on top. The structure is dipped into the bath by rotating it along a path that is substantially coplanar with the circuit structure. This is achieved by supporting the structure on a carrier 9 which in turn is attached to a motor shaft 11.Type: GrantFiled: June 5, 1995Date of Patent: June 10, 1997Assignee: International Business Machines CorporationInventors: Peter M. Banks, William M. Morgan

Patent number: 5460859Abstract: A method and system is disclosed in which an article, having large open areas or a multiplicity of apertures, is dip coated. The method and system is particularly adapted for use in coating a grid of a corona charging device utilized in the xerographic process. A transport system immerses and removes the article from a tank storing coating material. An unwanted coating material is created across the apertures of the article. Thereafter, the transport system moves the article past an ultrasonic wave source. The impact of the ultrasonic energy transmitted to the unwanted coating material across the apertures causes the removal thereof. The removed coating material is returned to the coating material in which the article was immersed.Type: GrantFiled: March 23, 1992Date of Patent: October 24, 1995Assignee: Xerox CorporationInventor: Louis Reale

Patent number: 5437723Abstract: A coating machine for the processing of chocolate and similar masses having a frame and a circularly driven grating belt supported thereon for the reception of the articles to be coated. The grating belt is guided by deflectors and has a tensioning device. Coating machine components are arranged below the upper run of the grating belt. The tensioning device has an extended travel enabling the lifting of the grating belt. A plurality of supports are provided to support the lifted grating belt, the supports including carriers on the frame of the coating machine.Type: GrantFiled: November 19, 1993Date of Patent: August 1, 1995Assignee: Sollich GmbH & Co. KGInventor: Helmut Sollich

Patent number: 5361964Abstract: Apparatus (1) for applying solder to electrical components such as integrated circuit packages (2) has a chamber (4) which contains a body of solder. The chamber (4) has outlet openings (10) which are below the surface of the solder and from which a flow of solder is provided. Since dross (oxidized solder) floats on the surface of the solder, the flow of solder is relatively pure. The leads of the packages are dipped into the flow of solder so that they are coated with a protective layer of solder. Vibrational apparatus (2) is also provided to vibrate the circuit packages (2) during the dipping of the packages (2) into the solder flow. In this way solder is prevented from bridging the spacing between two closely spaced, adjacent leads.Type: GrantFiled: March 17, 1993Date of Patent: November 8, 1994Assignee: Sun Industrial Coatings Private LimitedInventor: Ah T.

Patent number: 5338569Abstract: A method is disclosed for coating dowels with a substantially uniform coat of water soluble glue. A plurality of dowels and a preselected amount of liquid, water soluble glue are placed in a closed container. The container is rapidly shaken so that the container moves in a combination oscillating motion comprising an up and down movement and a back and forth movement that is substantially perpendicular to the up and down movement. Dowels coated with the liquid, water soluble glue are removed from the container and deposited on a drying surface. The dowels are dried by applying heat and a stream of air to the dowels. When the exposed surface of the coat of water soluble glue on the dowels has become essentially tack free but before the coat has dried completely, the dowels are rotated about their longitudinal axes so as to separate any dowels that are stuck together and to free any dowels stuck to the drying surface.Type: GrantFiled: April 14, 1993Date of Patent: August 16, 1994Inventor: J. Mel Hatch

Patent number: 5260098Abstract: A method of tinning tinnable areas of an electronic component package, the method comprising a first step during which additional metal is applied in the liquid state to said tinnable areas, and a following step during which at least one cycle of oscillations about an equilibrium position is applied to the package while said metal thus applied is still in the liquid state, for the purpose of setting up successive and opposite displacements of masses of said metal along said areas in order to obtain a uniform distribution of said metal over said areas.Type: GrantFiled: December 23, 1991Date of Patent: November 9, 1993Assignee: Alcatel CitInventors: Thierry Trentesaux, Yves Martin, Christian Daniel

Patent number: 5248456Abstract: An improved stereolithographic apparatus and method is described. In one embodiment, the improvement includes immersing at least a portion of a part in a volume of a liquid solvent in a vapor degreaser while subjecting the portion to ultrasonic agitation to substantially remove excess resin. Several examples of solvents are provided, including ethanol, and Freon TMS. In a second embodiment, the improvement includes building the part on a layer of liquid resin supported by a volume of a dense, immiscible, and UV transparent intermediate liquid, and integratably immersing at least a portion of the built part in the intermediate liquid, and then either subjecting the immersed portion to ultrasonic agitation to substantially remove excess resin, or subjecting the immersed portion to UV light. Several examples of intermediate liquids are provided, including perfluorinated fluids, such as Fluorinert FC-40, and water-based salt solutions, such as solutions of magnesium sulfate or sodium chloride in water.Type: GrantFiled: May 17, 1991Date of Patent: September 28, 1993Assignee: 3D Systems, Inc.Inventors: Herbert E.
