Patent number: 6789789Abstract: A two-stage vaporizer includes two vaporizing stages joined by a vaporization chamber located gravitationally below the first vaporizing stage and gravitationally above the second vaporizing stage. A separator covering an outlet within the vaporization chamber allows vaporized precursor from both vaporizing stages to pass through the outlet to chemical vapor deposition system and prevents any remaining liquid precursor from passing through the outlet. The liquid precursor is premixed with carrier gas just prior to entry into the vaporizer. Additional flows of carrier gas pass through the two vaporizing stages in opposite directions to carry the vaporized precursor to the outlet.Type: GrantFiled: May 29, 2002Date of Patent: September 14, 2004Assignee: Veeco Instruments Inc.Inventors: Rajul V. Randive, William J. Messner

Patent number: 6783117Abstract: A scent-emitting system includes a plurality of cartridges containing scented fluids and seated within pockets formed in a system tray. Heating members are provided for heating the cartridges to encourage the formation of scented vapors and an actuation subassembly is provided for selectively actuating the scent cartridges to release the scented vapors. An internal fan generates an air flow for communicating the scented vapors through housing vent openings to an external environment.Type: GrantFiled: June 20, 2002Date of Patent: August 31, 2004Inventor: Gregory D. Wohrle

Patent number: 6772999Abstract: A humidifier for use with a breathable gas supply apparatus includes a hollow body adapted for partial filling with water to a predetermined maximum water level, a gas inlet to the body above the maximum water level and a gas outlet from the body above the maximum water level. The humidifier further includes a constant temperature heating element for heating the water and/or an adjustable flow divider adapted to divide the interior of the body above the maximum water level into a relatively dry gas region and a relatively wet gas region. The position of the divider is variable so as to vary the relative proportion of the gas flowing from the inlet to the outlet that passes through the relatively dry and relatively wet gas regions to thereby vary the amount of humidification thereof.Type: GrantFiled: March 14, 2003Date of Patent: August 10, 2004Assignee: ResMed LimitedInventors: Matthew Lipscombe, Richard L. Jones

Publication number: 20040145067Abstract: The device comprises a base (1) and an exchangeable case (7), between which are placed corresponding components such as a bottle (9) containing the fragrant liquid and the corresponding wick (8), as well as the heating elements (4) connected to corresponding metallic contacts (5) and mounted on a support (3), also including a platform or printed circuit (2) with electronic components that allow optimizing the diffusion of the fragrance, to prevent olfactory saturation of the user, independently of the manual actuation means that allow regulating the intensity of evaporation of the fragrant liquid itself. The device also includes the corresponding plug (10) placed in correspondence with the part near the bottom end of the base (1).Type: ApplicationFiled: December 4, 2003Publication date: July 29, 2004Inventor: Jordi Basaganas Millan

Patent number: 6752387Abstract: A method of gasifying a liquid material that is entrained with a carrier gas includes mixing liquid material with a carrier gas in a control valve that can be heated. The gas-liquid mixture is maintain at a first pressure level that is sufficiently higher than the pressure level downstream of a nozzle in the valve to thereby provide a total gasification of the gas-liquid mixture. The control valve can position the liquid in a reservoir radially outward from a valve seat and an elongated mixing chamber can be positioned within the valve seat and connected to both a carrier gas and the release nozzle.Type: GrantFiled: September 13, 2000Date of Patent: June 22, 2004Assignee: Stec Inc.Inventors: Hiroshi Nishizato, Hideaki Miyamoto

Patent number: 6715743Abstract: A gas humidifier provides a continuous flow of gas through two stages of bubbling with an intermediate heating stage. Gas is introduced into an enclosure containing a quantity of bulk water by pumping the gas into a gas entry pipe or tube. The gas exits the gas entry pipe to bubble up through a bubbling evaporator. At the water surface of the bubbling evaporator, a heating element heats the gas-vapor mixture. The heated gas-vapor mixture then bubbles up through the bulk water, and the temperature of the bulk water determines the thermal cycles of the heating element. The gas-vapor mixture bubbles up through the bulk water, reaching saturation at the dew point. The saturated gas is then directed from the humidifier for use.Type: GrantFiled: April 9, 2002Date of Patent: April 6, 2004Inventor: Chaojiong Zhang
