Abstract:
A coating method and a coating apparatus are used to apply coating material to struts of a medical device (e.g., stent) which bound openings. The method involves optically scanning the medical device to produce position information identifying positions of the struts, using the position information to calculate a predetermined position, setting an applying manner to apply the coating material based on the predetermined position, setting an applying path accommodating the applying manner, and relatively moving the medical device and an applicator head along the applying route and path while dispensing the coating material from the applicator head and applying the coating material to the struts.
Abstract:
There is described an apparatus (1) for coating a cylinder (C), in particular a wiping cylinder of an intaglio printing press, with a plastic composition comprising inter alia a blade mechanism (4) comprising a single substantially planar blade (40) with a straight edge (40a) extending along the full length of the cylinder to be coated and which is mounted rotatably about an axis parallel to the axis of rotation of the cylinder to be coated. The blade comprises, at its terminal end proximate to the cylinder, an inclined end portion (4a) having an inverted-V shape rising from the upper side of the blade, the top edge of the inclined end portion forming the straight edge of the blade. The blade is adapted to be rotated so that the straight edge of the blade undergoes an upward movement substantially tangential to the periphery of the cylinder in order to discontinue the application of the plastic composition onto the surface of the cylinder.
Abstract:
A stent with at least one severable supporting device and methods of coating using the same are disclosed. The severable supporting device can be an end tube or a tab attached to some portion of the stent by at least one “gate” or attachment. The end tube or tab may be part of the design of the stent when it is originally manufactured, or it may be attached to the stent in a secondary process by a biocompatible glue or solder. The end tube or tab can be used to support a stent during a coating process eliminating the need for a mandrel which would otherwise contact the stent during the coating process.
Abstract:
A painting tool for painting a vehicle wheel is disclosed. The tool includes a base and a plurality of idler wheels rotatably coupled to the base. The wheels are disposed about the base to rotatably support a workpiece. A motor is coupled to the base and includes a motor output disposed to engage the workpiece and to rotate the workpiece on the plurality of idler wheels about a workpiece axis. A mask is operatively coupled to the base. The mask is movable between an engaged position wherein the mask obscures a portion of the workpiece and a disengaged position wherein the mask is disposed away from the workpiece. A method of painting a vehicle wheel is also disclosed.
Abstract:
A coating method, which uses a coating apparatus including a rotatable tray having a recessed portion for accommodating a substrate and rotatable together with the substrate, a nozzle for supplying a coating liquid, and an applicator for spreading the coating liquid, includes the steps of placing a substrate into the recessed portion of the tray, positioning the nozzle over a non-recessed portion of the upper surface of the tray, supplying a coating liquid from the nozzle, and forming a coating liquid pool only on the non-recessed portion of the upper surface of the tray, moving the applicator in a horizontal direction while maintaining a certain distance with respect to the upper surface of the substrate for spreading the coating liquid of the coating liquid pool over the entire upper surface of the substrate, and releasing the substrate from the recessed portion of the tray.
Abstract:
Embodiments of the invention relate to a method and apparatus for coating a medical device. In one embodiment, the method for preparing a substantially uniform coated medical device includes (1) preparing a coating solution comprising a solvent, a therapeutic agent, and an additive; (2) loading a metering dispenser with the coating solution; (3) rotating the medical device about the longitudinal axis of the device and/or moving the medical device along the longitudinal or transverse axis of the device; (4) dispensing the coating solution from the metering dispenser onto a surface of the medical device and flowing the coating solution on the surface of the medical device while the medical device is rotating and/or linearly moving; and (5) evaporating the solvent, forming a substantially uniform coating layer on the medical device.
Abstract:
A method for treating the inside surface of a glass container includes applying a polysilazane solution to the inside surface of the glass container, drying the polysilazane while the glass container is rotated in the state of being inverted and inclined 50° to 70° with respect to horizontal, and sintering the polysilazane. During the sintering, the sintering temperature is 300° C. to 600° C. and the sintering time is 10 minutes or more. The method may also include applying at least one of a sulfur dioxide gas, a sulfur trioxide gas, a chlorine gas, and a chlorofluorocarbon gas to the inside surface of the glass container under heating, during which the average temperature of the glass container may be 500° C. to 700° C.
