Abstract:
The present invention relates to an electrospinning nozzle module for drug coating and, more specifically, to an electrospinning nozzle module for drug coating which can effectively coat an object such as a stent with the drug by electrospinning. The electrospinning nozzle module for drug coating of the present invention, which coats an object with the drug by spraying the drug, comprises the following: a housing having a discharge hole formed at one end through which a nitrogen gas supplied from the outside is sprayed to the outside; and a nozzle part having one end inserted into the discharge hole to spray the drug to the outside and the other end to which electricity is supplied, wherein the discharge hole is disposed on the circumference of one end of the nozzle part, and the nitrogen gas is sprayed together with the drug through the circumference of the one end of the nozzle part when the drug is sprayed through the one end of the nozzle part.
Abstract:
A method of powder coating a substrate includes receiving a powder coating material into a feed input, using the feed input, melting the powder coating material into a homogeneous fluid of powder coating material, receiving the homogeneous fluid of powder coating material into a filament extension atomizer positioned in-line with the feed input, atomizing, with the filament extension atomizer, the received homogeneous fluid of powder coating material into multiple droplets of powder coating material, cooling the droplets of powder coating material to a processing temperature that prevents the droplets from agglomerating, and directing the cooled droplets through a deposition passage positioned in-line with the filament extension atomizer, the deposition passage configured to direct at least a portion of the cooled droplets towards a substrate.
Abstract:
A powder supplying device (2) includes a case (6) in which a storage portion (6a) is formed for temporarily storing powder (10), the case (6) having an inlet (6b) formed in an upper end of the storage portion (6a), and a rectangular outlet (6c) formed in a lower end of the storage portion (6a); a rotor (7) that is arranged in the case (6) and transports the powder (10) in the storage portion (6a) to the outlet (6c) by rotating; and a mesh body (8) through which the powder (10) that has been transported to the outlet (6c) passes. The powder supplying device (2) supplies the powder (10) onto an upper surface of an electrode foil (5). The rotor (7) has a brush-like shape, with a plurality of hair members (7b) radially implanted pointing radially outward with an axial center (G) of the rotor (7) as the center.
Abstract:
Systems and methods for magnetically autonomously clamping a downhole component in a select direction of a borehole casing. The systems can include a sensor package that obtains a downhole measurement in a position in a cased borehole. The systems can include an integral magnetic clamp that removably clamps the downhole component (e.g., a downhole seismic shuttle) to the cased borehole. The systems can include a directional detector that outputs a select direction of the cased borehole relative to the downhole component. The systems can include a downhole controller that activates a portion of the integral magnetic clamp of the downhole component closest to the select direction output by the directional detector.
Abstract:
A powder coating system which is provided with a rotating stage which makes a metal cylindrical member rotate while holding its internal circumferential surface, a first booth which covers part of the metal cylindrical member which is held by the rotating stage, and a second booth which holds the first booth. A powder coating introduction nozzle which is provided with a filling port of powder coating and a plurality of powder coating spray ports is provided so that a filling port is positioned at the outside of the second booth and so that the plurality of spray ports can be changed in position in the first booth to face surface parts of the metal cylindrical member. The sprayed powder coating is collected inside the second booth by a flow of air from a blow device and is removed by being sucked up by a powder collector.
