The colorant dispenser further comprises a piston disposed in the colorant chamber, and a push rod coupled to the piston operable to advance the piston toward the dispensing tip to exude the specified amount of colorant onto the painting surface. The system further includes an air nozzle coupled to the colorant dispensing tip operable to direct pressurized air to modify at least one of the two-dimensional coverage and three-dimensional profile of the colorant dot on the painting surface.
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:
Disclosed are an air bubble ingress prevention mechanism, a liquid material discharge device provided with the air bubble ingress prevention mechanism, and a liquid material discharge method, with which a constant filled state can be achieved without variations and without requiring any additional equipment when a metering section is filled with liquid material. A discharge device is provided with a metering section which has a flow passage communicating with a nozzle, and a plunger which moves back and forth within the flow passage of the metering section. The discharge device comprises an air bubble ingress prevention mechanism which can be mounted at the end of the metering section on the opposite side to the nozzle, and which includes: a first hole which communicates with the flow passage of the metering section, and within which the plunger moves back and forth; a first sealing member which is provided at the end of the first hole at the nozzle side; a second sealing member which is provided at the end of the first hole at the opposite side to the nozzle; and a second hole which communicates with the side face of the first hole.
Abstract:
A fluid dispensing system may include a first die portion having a first face defining a first edge and a second die portion spaced from the first die portion and having a second face facing the first face and defining a second edge, wherein the first edge and the second edge define a fluid outlet opening. The fluid dispensing system may also include a fluid inlet for introducing fluid to a region between the first face and the second face, and a cavity in flow communication with the fluid inlet, wherein the cavity opens to the region between the first face and the second face. The fluid dispensing system may further include a shim disposed between the first die portion and the second die portion to maintain the spaced positioning of the first and second die portions, wherein the shim defines a plurality of channels bounded by the first and second faces and extending from the cavity in a direction toward the fluid outlet.

Furthermore the present invention concerns coating processes for the manufacture of these balloon catheters as well as their use in the treatment and prophylaxis of vascular diseases.
Abstract:
Material treatment compositions for various materials and methods of treating the same is disclosed. A material treatment composition includes at least one silane-containing material, at least one base-containing material, and at least one solvent to enhance the strength of a material contacted by the composition.
Abstract:
The present invention pertains to a process for manufacturing a component of a secondary battery, said process comprising the following steps: (i) preparing a liquid composition comprising: —a liquid medium selected from the group consisting of aliphatic ketones, cycloaliphatic ketones, cycloaliphatic esters and mixtures thereof, and —at least one fluorinated polymer [polymer (F)] comprising recurring units derived from vinylidene fluoride (VDF), hexafluoropropylene (HFP) and at least one (meth)acrylic monomer (MA) having formula (I), wherein: —R1, R2 and R3, equal to or different from each other, are independently selected from a hydrogen atom and a C1-C3 hydrocarbon group, and —Rx, is a hydrogen atom or a C1-C5 hydrocarbon moiety comprising at least one functional group selected from a hydroxyl, a carboxyl, an epoxide, an ester and an ether group; and (ii) processing said liquid composition to provide a film.
Abstract:
A method is provided for joining a filler material to a substrate material. The method includes melting the filler material within a melting chamber of a crucible such that the filler material is molten. The crucible has an outlet fluidly connected to the melting chamber. The method also includes holding the filler material within the melting chamber of the crucible by applying a first pressure differential across the outlet of the crucible, and releasing the filler material from the melting chamber of the crucible by applying a second pressure differential across the outlet of the crucible to deliver the filler material to a target site of the substrate material. The second pressure differential has a different value than the first pressure differential.
