Disclosed is an apparatus and associated method for tagging insects and arthropods. According to an exemplary embodiment of this disclosure, an electrosprayer is provided including a nozzle cartridge, a spray chamber removably attached to the nozzle cartridge and a power supply operatively connected to the nozzle cartridge and a grounding plate within the spray chamber to electrically charge droplets expelled from the nozzle which coat one or more insects contained in the spray chamber.

An electrostatic painting device capable of reducing any AC or electromagnetic emissions when the device is powered on is provided. The emissions affect electronic components present during painting of various objects or even when the device is powered on. The electromagnetic induction into the conductive circuit elements in turn induces voltages and currents, which potentially harm the micro-electronic circuits. One such device includes a choke between a fluid tip and a high voltage source of the device to reduce these emissions. The voltage source may include at least one capacitor which supplies the AC emissions representing electromagnetic emissions risk during the discharge of paint from the device. The choke connected to the voltage source substantially reduces the emissions involved during the paint discharge, while allowing the discharge of electrons, thereby imparting negative DC charge to the paint and the workpiece, and preventing damage to electronic circuits during the process.

There is provided a substrate processing apparatus that includes: a process chamber in which a substrate is accommodated to be processed; a plurality of quartz gas nozzles configured to supply, into the process chamber, a plurality of process gasses capable of generating reaction products by reacting the plurality of process gasses with each other; an evacuation device configured to evacuate an interior portion of the process chamber; a bypass pipe configured to connect a quartz gas nozzle among the plurality of quartz gas nozzles to the evacuation device; and a coating gas nozzle configured to supply at least one of a silicon-containing gas and an oxidizing gas capable of forming a SiO.sub.2 coating film inside the quartz gas nozzle connected to the evacuation device in a state in which the inside of the quartz gas nozzle connected to the evacuation device is evacuated by the evacuation device.

An electrostatic coating device is provided with a housing, which has a cascade housing section that houses a cascade, and a motor housing section that houses an air motor. A clearance between the cascade and the inner wall of a first housing hole forms a first air flow passage. Furthermore, an annular clearance between the air motor (specifically, an air turbine) and the inner wall of a motor chamber forms a second air flow passage. The first air flow passage and the second air flow passage are communicated with each other via, for instance, a third air flow passage that includes a first communication passage, a circular recessed section, a second communication passage, and a third communication passage.

Electrospray devices are described. The devices may comprise a substrate and a plurality of emitters. The emitters may comprise a plurality of channels therein, wherein the channels may be configured to convey immiscible liquids to the distal end of the emitters. The channels may be arranged such that, at the distal end, one liquid enclosed another liquid. The device may comprise a plurality of reservoirs, each reservoir being configured to contain liquid therein and to convey the liquid to a respective channel. Core-shell droplets may be formed by forming Taylor cones through the application of an electric field. The core-shell droplets may include a core liquid enclosed within a shell liquid, wherein the two liquids may be immiscible.

A system may include an electrostatic spray tool having a turbine generator configured to generate electrical power to electrostatically charge a spray. The spray tool also may include a controller configured to monitor the electrical power from the turbine generator and to instruct a gas supply to vary a gas flow to the turbine generator based on feedback received from one or more sensors.

An electrode device includes a discharge electrode and a counter electrode, and discharges when a voltage is applied across the discharge electrode and the counter electrode. The discharge electrode is a columnar electrode having a discharge portion on its front end. The counter electrode faces the discharge portion. The counter electrode has a peripheral electrode portion and a projecting electrode portion. The peripheral electrode portion is disposed to surround an axis of the discharge electrode. The projecting electrode portion projects from a part of the peripheral electrode portion toward the axis of the discharge electrode. A distance from the peripheral electrode portion to the discharge portion is shorter than a distance from the projecting electrode portion to the discharge portion.

The electrospray device comprises a sprayer comprising a sprayer body and nozzle, and a partition positioned vertically and coaxially with the sprayer. The sprayer body is provided with a swirl generator for generating a swirling air stream, and a power supply connected between the nozzle and the partition, to apply voltage to the nozzle and the partition. The electrospray device may be part of a fluidized bed apparatus comprising a product container, a lower plenum base, an air distribution plate resided therebetween. When the power supply applies voltage in opposite polarities to the nozzle and the partition, the fluidized bed apparatus is used for coating particles; and when the power supply applies voltage of the same, the fluidized bed apparatus is used for spray-drying a solution. The electrospray device uses an electromagnetic hydrodynamic method to improve the performance of the fluidized bed apparatus and optimize the process of product.

An insulated electrostatically-assisted insulated spraying extender (10) is described, which is installed on the spraying bar (100) of a spraying device and positioned adjacent to a hydraulic nozzle (20) that atomizes the spray solution, said extender (10) being equipped with an insulated internal shaft (12) for the passage of the power supply cable (30) and the placement of an encapsulated electric device (13) that feeds the induction electrode (151) surrounding the opening (21) of the hydraulic nozzle (20), causing the dielectric rupture of atomized drops, eliminating or decreasing the wetting of the induction electrode (151) and of the power supply cable (30), as well as of other electric parts that affect the efficiency and the full operation of the spraying nozzle, while hindering leakage of the electric current through cable (30) by contacting any section of the machine structure.
