    Abstract: This invention generally relates to systems and methods for the formation and/or control of fluidic species, and articles produced by such systems and methods. In some cases, the invention involves unique fluid channels, systems, controls, and/or restrictions, and combinations thereof. In certain embodiments, the invention allows fluidic streams (which can be continuous or discontinuous, i.e., droplets) to be formed and/or combined, at a variety of scales, including microfluidic scales. In one set of embodiments, a fluidic stream may be produced from a channel, where a cross-sectional dimension of the fluidic stream is smaller than that of the channel, for example, through the use of structural elements, other fluids, and/or applied external fields, etc. In some cases, a Taylor cone may be produced.

  • Patent number: 8985051
    Abstract: A coating apparatus produces a spray of charged droplets and controls the spray angle of travel of the spray toward the object to be coated. Electrically charging droplets minimizes the amount of coating material required to uniformly coat a surface as compared to conventional web coating techniques such as blade coating. An inductive ring guides the spray charged droplets as they exit the nozzle of a spray device. The electrostatic repulsion between the charged droplets insures that a uniform coating of liquid formulation can be applied to a web surface.

An emitter assembly includes having a deformable end portion, an inlet near the deformable end portion to receive the sample eluent from the microfluidic substrate, and an electrically conductive outlet portion to emit a spray of the sample eluent. A force-applying unit applies a force to the emitter assembly that urges the deformable end portion into contact with the microfluidic substrate. The deformable end portion is more elastic than the microfluidic substrate so that the contact between the microfluidic substrate and the deformable end portion produces a substantially fluid-tight seal between the outlet aperture of the microfluidic substrate and the inlet of the emitter assembly.

    Abstract: An electrostatic spraying device has a removable cartridge with a reservoir containing a volume of liquid compositions to be electrically sprayed. The device includes a nozzle for dispensing the liquid and an emitter electrode disposed adjacent to the nozzle for charging the liquid composition just being dispensed from the nozzle. A field electrode surrounds the reservoir in order to charge the liquid composition within the reservoir, thereby avoiding an occurrence of electric current which would deteriorate the composition remaining in the reservoir. The reservoir is at least partially made of deformable material such that the reservoir is capable of receiving pressure to deform and thus supply the liquid composition out of the reservoir. Thus, the reservoir can be designed into a simple and compact structure, thereby providing an increased liquid containing volume in relation to the bulk of the removable cartridge.

  • Patent number: 7823808
    Abstract: An electrostatic spraying device having a removable cartridge with a reservoir containing a volume of liquid compositions to be electrically sprayed on a user's skin. The device includes a nozzle for dispensing the liquid as well as an emitter electrode disposed adjacent to the nozzle for charging the liquid composition just being dispensed from the nozzle. A field electrode surrounds the reservoir in order to charge the liquid composition within the reservoir, thereby avoiding an occurrence of electric current which would otherwise flow in the liquid composition and would deteriorate the composition remaining in the reservoir. The reservoir is devoid of the field electrode, and therefor can be designed into a simple and compact structure without being restricted by the field electrode, assuring to have an enhanced liquid containing volume in relation to the bulk of the removable cartridge.

  • Patent number: 7823809
    Abstract: An electrostatic spraying device has a capability of confirming that the device is ready for making an electrostatic spraying of the liquid composition on a user's skin. The device includes a nozzle and a pump for dispensing the liquid composition out through the nozzle. An emitter electrode is disposed to electrostatically charge the liquid composition being dispensed for making the electrostatic spraying. The device is provided with a power switch and a selector for selection between a spraying mode and a dripping mode. In the dripping mode, the pump is alone actuated to dispense the liquid composition absent electrostatic charge. In the spraying mode, both of the pump and the emitter electrode are activated to make the electrostatic spraying. Thus, the user can be easy to drip the liquid composition by simply manipulating the selector prior to initiating the electrostatic spraying.

    Abstract: An airflow passage of an air conditioner includes an intake port, which draws in air, and an outlet port, which is in communication with the intake port and emits air conditioning current. An electrostatic atomization device used with the air conditioner is in communication with the airflow passage and includes a discharge electrode, a water supply device, which supplies water to the discharge electrode, and a high voltage application device, which applies high voltage to the discharge electrode and generates charged micro-particle water through electrostatic atomization. The electrostatic atomization device additionally generates ozone when generating the charged micro-particle water and emits the ozone into the airflow passage with the charged micro-particle water. A controller controls concentration of the ozone emitted from the outlet port of the airflow passage at an appropriate concentration during operation of the air conditioner.

    Abstract: A housing member includes a main housing body and an intermediate tube provided around the outer periphery of the main housing body. Located in a front portion of the main housing body is an atomizer including an air motor and a rotary atomizing head, while located in a rear portion of the main housing body is a high voltage generator to apply a high voltage to paint through the air motor. A multitude of hollow cavities are uniformly formed in the intermediate tube over the entire outer surface thereof by the use of through holes opened through the intermediate tube. A cover member is fitted on the outer surface of the intermediate tube in contact with the intermediate tube, thereby intensifying electric field strength in outer corner portions of the hollow cavities to prevent deposition of charged paint particles.

    Abstract: The present invention of collecting gaseous sample employs the sealable container, the inlet mounted at a part of the container, the outlet mounted at the other part of the container, the atomizing electrode mounted in the container, the primary refrigerator mounted at adjacent to the atomizing electrode, the opposite electrode mounted in the container, the acicular capture electrode mounted at adjacent to the opposite electrode, and the secondary refrigerator mounted at adjacent to the capture electrode. Charged microparticles are prepared by chilling gaseous sample and producing condensate of the same. Such charged microparticles are collected by the capture electrode with static electricity, and they are condensed by chilling them. This method prevents the capture electrode from spreading solution thereon.

  • Patent number: 7694645
    Abstract: An air source (11) is connected to an air motor (3) through an electropneumatic converter (12) which is connected to a rotational controller (13). Upon changing settings in a target rotational speed (N0) or paint discharge rate (Q0), in order to supply a necessary air pressure for rotationally driving the air motor (3) in a steady state with new setting conditions, the rotation controller (13) selects a steady value (is) from a rotational data selection processing table, and outputs to the electropneumatic converter (12) the newly selected steady value (is) as an input current value (i). By so doing, the rotational speed of the air motor (3) is quickly controlled toward the changed target rotational speed (N0).
