The velocity-profile modifying device is set at the air moving track and is used for modifying a first velocity-profile of airflow by the air pouring apparatus to a second velocity-profile and further for making the air distribute evenly toward the heat component. By providing the velocity profile modifying device, a better distribution of the airflow toward the heat component and a stable temperature status of the heat component can be achieved.Type: GrantFiled: November 8, 2004Date of Patent: April 24, 2007Assignee: Benq CorporationInventors: Bang-Ji Wang, Chang-Chien Li, Chun-Ming Shen

Patent number: 7207498Abstract: A fluid dispense tip includes a bevel at an opening to reduce the amount of surface tension, or “land”, at the opening. The bevel is formed by grinding in a longitudinal direction such that any tooling scars resulting from the grinding operation are likewise longitudinally oriented, further reducing the amount of surface tension in the tip, thereby leading to heightened dispensing accuracy. The tip may be machined from stock as a unitary piece, to increase its lifetime, and may be formed with a bore of a relatively large diameter that is tapered down to a smaller diameter near the tip opening, to allow for delivery of fluid through the tip body at a decreased pressure. A cleaning tool may be provided for removing residual material from the inner surfaces of the tip. A removable liner sleeve may be provided within the bore to reduce the effective inner diameter of the dispense tip.Type: GrantFiled: February 23, 2005Date of Patent: April 24, 2007Assignee: DL Technology, LLCInventor: Jeffrey Fugere

Patent number: 7201335Abstract: A nozzle system is provided comprising a nozzle tip supported in a nozzle body with an alignment member. The alignment member has a connection for engaging a corresponding connection located on the nozzle body. The alignment member also has an aperture concentric with the sleeve that has a tapered engagement surface for contacting a tapered engagement surface on the nozzle tip. A first melt channel is defined through the nozzle body and a second melt channel is defined through the nozzle tip. The melt channel in the nozzle tip has a first section that extends along a first axis from an inlet, a second section that extends from the first section at an incline and a third section that extends from the second section parallel to and eccentric with the first axis. The resulting melt channel defines a straight through channel parallel to said first axis from said inlet to said opening.Type: GrantFiled: July 13, 2004Date of Patent: April 10, 2007Assignee: Mold-Masters LimitedInventors: Denis Babin, Helen Zhuang

Patent number: 7152810Abstract: A micro-droplet generator, comprising a chamber, enclosed by a casing, a spraying plate, having a plurality of spraying holes, a piezoelectric plate, a signal connector, and a storage tank. The piezoelectric plate is mounted inside the chamber, having a fixed end fastened on the casing and a free end performing a bending movement. The input port issues signals that cause the bending movement of the piezoelectric plate. The chamber and the storage tank contain liquid, with a constant difference of liquid levels in the chamber and the storage tank being maintained, so that negative pressure in the chamber is automatically regulated.Type: GrantFiled: February 23, 2004Date of Patent: December 26, 2006Assignee: Industrial Technology Research InstituteInventors: Tien-Ho Gau, Yu-Yin Peng, Chin-Pin Chien

Patent number: 7143967Abstract: A cold gas spraying method and device, whereby the sprayed particles are accelerated in a gas flow. A powder tube and an outer nozzle body together form a Laval nozzle that produces high gas flow velocities. The injection of the sprayed particles occurs in the divergent section of the Laval nozzle.Type: GrantFiled: November 26, 2003Date of Patent: December 5, 2006Assignee: Linde AktiengesellschaftInventors: Peter Heinrich, Thorsten Stoltenhoff, Peter Richter, Heinrich Kreye, Horst Richter

Patent number: 7131600Abstract: An atomization chamber apparatus used for aircraft pesticide delivery, which has an open ended walled chamber, divided into left and right sections, each having outer and inner segments, each segment having a top and a bottom wall, the outer segments having a same radius concave upper wall and a convex lower wall, while the inner segments have a same radius convex radius upper wall and a concave lower wall. A nozzle injector connectable to a fluid pesticide source is laterally disposed in an inner segment. The nozzle is chosen such that exiting pesticide will not impact the chamber walls, and the radii of the segments are chosen such that the speed of pesticide atomization by the incoming air is slowed down to reduce fines upon pesticide impact, and the speed of the pesticide air mixture on exiting the chamber is increased to substantially match the airspeed of the aircraft.Type: GrantFiled: December 4, 2003Date of Patent: November 7, 2006Inventor: Russell Stocker

Patent number: 7090155Abstract: A spray nozzle of two piece structure threaded together and including a fitting for mounting on a pressurized liquid supply pipe and including an orifice controlling liquid flow to a one piece molded nozzle of plastic material screw threaded onto the fitting. The nozzle includes spaced longitudinal side walls interconnected by a top wall and a bottom slot. A diffuser plate or blade is mounted between the side walls at the discharge end of the nozzle. The side walls of the nozzle converge from the inlet end of the nozzle toward the nozzle blade or plate at the discharge end. Each side wall converges toward the center line of the nozzle at an angle ranging between 1° and 3°. A thin metal plate forms a closure for a major portion of the length of the bottom slot with a rearward end having an air inlet below the orifice in the fitting to draw air into the nozzle as liquid exits the orifice into a larger volume area at a reduced pressure.Type: GrantFiled: March 1, 2004Date of Patent: August 15, 2006Inventor: Benjamin Franklin Rabitsch

Patent number: 6942168Abstract: A spray nozzle for spraying a fluid and suitable for use in hot corrosive environments is disclosed, comprising a single piece body comprising a top and a bottom disposed opposite the top where the bottom further comprises a connector; a channel disposed about an outer portion of the single piece body intermediate the bottom and the top, the channel extending from the outer portion of the single piece body and terminating at an interior wall; and a fluid passageway in fluid communication with the bottom and with the channel. The channel may disperse fluid at a predetermined angle defined by the outer portion of the single piece body and the interior wall of the channel with respect to an axis defined by the fluid passageway. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure.Type: GrantFiled: March 11, 2003Date of Patent: September 13, 2005Assignee: WaferTech, LLCInventors: Trent Rance, Chris Warberg

Patent number: 6883735Abstract: A nozzle for a liquid dispenser that incorporates a cleaning probe capable of removing foreign debris from a nozzle discharge passageway. The cleaning probe is moveable between a retracted position that permits fluid flow to a discharge orifice terminating the discharge passageway and an extended position in which the cleaning probe extends into the discharge passageway. As the cleaning fixture advances from the retracted position to the extended position, foreign debris present in the discharge passageway is displaced and ejected out of the discharge orifice.Type: GrantFiled: April 21, 2003Date of Patent: April 26, 2005Assignee: Nordson CorporationInventor: Charles P. Ganzer

Patent number: 6854671Abstract: A nozzle ejects molten metal in an ejecting direction. The nozzle has a solder-philic surface in a first region and a solder-repellent surface in a second region. The second region is located forward of the first region in the ejecting direction. Before molten metal is ejected, the peripheral edge of the liquid surface of the molten metal is held at a position located further forward in the ejecting direction than the boundary between the solder-philic surface and the solder-repellent surface. The peripheral edge of the liquid surface is thus held before being ejected so that solder drops can be ejected steadily with a uniform diameter, constant direction, and constant speed.Type: GrantFiled: October 22, 2002Date of Patent: February 15, 2005Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Jyunichi Aizawa, Hiroshi Fukumoto, Yasufumi Nakasu
