Abstract:
The present technique provides a system and for improving control of a needle valve in a spray coating device. An exemplary spray coating device of the present technique has a needle valve assembly that controls entry of a fluid to a fluid delivery tip. The needle valve assembly includes an adjustment element that is at least partially located on an exterior of the spray coating device such that the adjustment element is accessible by an operator. The adjustment element may be actuated to improve a seal around the needle so that fluid does not leak from around the needle valve assembly.

Microchips which are particularly suitable for use with a mass spectrometer include a microchip body with at least one fluid channel formed into the microchip body and at least two flat monolithic closely spaced integrated ESI (electrospray ionization) emitters defined by shaped projections formed to extend from one side of the microchip body, a respective one being in fluid communication with a fluid channel. Related systems and methods are also described.
Abstract:
A multiplexed emitter source distributor electrode, a related multiplexed electrospray nozzle, a related multiplexed electrospray apparatus and a related coating method that uses the multiplexed electrospray apparatus are all predicated upon at least one of: (1) a linear emitter source density greater than about 15 emitter sources per centimeter; and (2) an area emitter source density greater than about 225 emitter sources per square centimeter. The distributor electrode comprises other than a silicon material (i.e., a metal, metal alloy, ceramic or polymer material). The distributor electrode may be fabricated using a computerized numerical control method that provides the coating method with enhanced uniformity. The nozzle and the apparatus may also use a stepped slotted extractor electrode.
Abstract:
A method of manufacturing a ferroelectric thin film on a lower electrode by electrostatically spraying a ferroelectric thin film-forming sol-gel solution from a spout of a capillary toward the lower electrode of a substrate having the lower electrode so as to coat the sol-gel solution on the lower electrode and form a coated film, drying, calcining, and then firing the coated film so as to crystallize the coated film, in which a distance between the spout of the capillary and the lower electrode and an applied voltage during electrostatic spray are set so that a refractive index during drying and calcination of the coated film becomes 2 or more, and a film thickness sets in a range of 150 nm or less when the sol-gel solution is coated in a single spray process, calcined, and then fired so as to be crystallized.
Abstract:
An electrostatic atomization system for a vehicle includes an electrostatic atomization device that generates and emits charged micro-particle water from an emission port, a vehicle interior introduction port arranged in an instrument panel in a vehicle interior, and a communication duct that connects the emission port and the vehicle interior introduction port to emit the charged micro-particle water from the vehicle interior introduction port to the vehicle interior. The communication duct includes a first curved portion, which is arranged between the emission port and the vehicle interior introduction port and curved downward in a lower position than the vehicle interior introduction port, and a second curved portion, which is arranged between the first curved portion and the emission port and curved upward in an upper position than the first curved portion.
Abstract:
An electrostatic atomizer comprises an atomization unit provided with a microstrip line having first and second ends, a microwave input unit configured to input a microwave signal to the first end, and a liquid supply means configured to supply liquid to the second end side. Consequently, the emission of ozone with charged particulate water containing an active ingredient can be suppressed while the amount of generation of the charged particulate water is ensured.
Abstract:
Systems and methods for coating medical devices are provided that allow for relatively precise control over the deposition area and coating uniformity with improved efficiency. A microdrop source is used to provide a flow of coating microdrops. A charging electrode disposed near the outlet of the coating source gives each microdrop an electrostatic charge. As the microdrop travels toward the medical device to be coated, a control electrode alters the trajectory of the microdrop. The invention can include a scanner to scan or image the medical device as the coating is applied and a control system to adjust parameters of the deposition process based on information provided by the scanner.
Abstract:
A composite of electrode active material including aggregates formed by self-assembly of electrode active material nanoparticles and carbon nanotubes, and a fabrication method thereof are disclosed. This composite is in the form of a network in which at least some of the carbon nanotubes connect two or more aggregates that are not directly contacting each other, creating an entangled structure in which a plurality of aggregates and a plurality of carbon nanotube strands are intertwined. Due to the highly conductive properties of the carbon nanotubes in this composite, charge carriers can be rapidly transferred between the self-assembled aggregates. This composite may be prepared by preparing a dispersion in which the nanoparticles and/or carbon nanotubes are dispersed without any organic binders, simultaneously spraying the nanoparticles and the carbon nanotubes on a current collector through electrospray, and then subjecting the composite material formed on the current collector to a heat treatment.
Abstract:
The present technique provides a system and method for improving a tip assembly for a spray coating device. An exemplary spray coating device of the present technique has a twist tip with air-assist channels. The twist tip may be applied to a spray gun and provides a portion of the fluid flow passage of the gun. Rotation of the twist tip alters the fluid flow path, resulting in increased operator control.
