| 20090108094 | SYNTHETIC JET AIR FRESHENER - An air freshening device comprises a housing defining a chamber. The chamber contains air and a supply of fragrance material that scents the air inside the chamber. A mechanical oscillator is in fluid communication with the air in the chamber and is configured to transmit acoustic waves in the chamber. A narrow conduit provides a passage from an interior of the chamber to the atmosphere outside the chamber. The conduit is dimensionally configured such that a synthetic jet from the narrow conduit is generated upon activation of the mechanical oscillator, the synthetic jet ejecting scented air from the chamber interior to the atmosphere outside the chamber. The mechanical oscillator may be driven intermittently, resulting in a consistent intensity and character of the emitted scent over the life of the product. | 04-30-2009 |

| 20100127096 | LOW-SPEED PULSATING SHOWERHEAD - A showerhead may include a housing, a turbine, and a shutter. The housing may include a fluid inlet, at least one fluid outlet, and a chamber in fluid communication with the inlet and one or more outlets. The turbine and shutter may be placed in the cavity. The shutter may include at least one opening. The shutter may selectively cover and uncover fluid outlets, thus selectively fluidly connecting the fluid outlets with the chamber. Water flowing through the housing causes the turbine to spin. As the turbine spins, the shutter rotates at a slower speed than the turbine to produce a periodic interruption of water flow through the outlets by covering and uncovering the outlets as the shutter rotates within the housing. | 05-27-2010 |
| 20100252650 | FUEL INJECTION DEVICE - A fuel injection device includes a pressure control portion for controlling operation of a nozzle, and a body portion having therein a bent lead wire hole through which two lead wires of the pressure control portion are introduced to exterior.

The first partition member protrudes from one end portion of the first guide member to have a protrusion portion, which is fitted with a recess portion of the second partition portion at one end portion of the second guide member when the first and second guide members contact. | 10-07-2010 |
| 20110192913 | CLEANING METHOD AND FLUID EJECTING APPARATUS - A method for cleaning a fluid ejecting apparatus is provided. The fluid ejecting apparatus includes a fluid ejecting head that has a plurality of nozzle openings through which fluid is ejected, a fluid supply passage through which the fluid is supplied toward the fluid ejecting head, an open/close valve that is provided on the fluid supply passage, and a pressure reduction mechanism that generates negative pressure in a space outside the nozzle openings. The cleaning method includes a valve-closing operation of putting the open/close valve into a closed state and a pressure reduction operation of generating negative pressure in the space by using the pressure reduction mechanism after the valve-closing operation to cause the fluid to bulge outward at the nozzle openings. | 08-11-2011 |
| 20110233300 | ATOMIZATION UNIT WITH NEGATIVE PRESSURE ACTUATOR - An atomization unit is described that employs a negative pressure actuator to reduce the fluid pressure acting on the atomizer in order to minimize or prevent fluid leakage from the atomizer. Methods of minimizing or preventing fluid leakage from an atomizer through use of a negative pressure actuator are also described. The atomization unit is particularly suitable for use in a refrigerator to cool and humidify at least a portion of the refrigerator. | 09-29-2011 |
| 20110233301 | Rain can style showerhead assembly incorporating eddy filter for flow conditioning in fluidic circuits - A fluidic oscillator adapted for use in a showerhead or nozzle assembly includes an eddy filter structure which reduces the adverse effects of fluid supply turbulence on the fluidic oscillator's spraying performance. A nozzle or rain can style showerhead assembly includes a water chamber or manifold which receives water via a central inlet fitting. Water entering the water chamber or manifold flows turbulently into and through the manifold and is expelled under pressure through a plurality of nozzles which are configured as specially adapted fluidic inserts. | 09-29-2011 |
| 20120056010 | Automatic flow regulation sprinkler for gardening - An automatic flow regulation sprinkler for gardening includes a base having a linking first water way and second water way on opposite sides thereof. Two outer ends of a transverse axle tube communicates the first water way and the second water way respectively. The transverse axle tube has at least one water outlet.
