Abstract:
The present invention is intended to solve a problem that a coating film has an uneven thickness in the case where a coating target 1 has a stepped portion extending in a predetermined direction on its coating surface. To solve the problem, a follow-up coating is performed along the stepped portion S extending in the predetermined direction after coating of the entire coating surface of the coating target 1 so that paint mist adheres more to a relatively-recessed side of the stepped portion S.
Abstract:
A rotary atomizing head (7) is provided with an outer peripheral surface washing passage (14) open onto anatomizing head outer peripheral surface (13) for causing wash fluid supplied from a feed tube (6) to flow out into an annular clearance (20) between the rotary atomizing head (7) and a shaping air ring (15). An outflow opening (14C1) of an outflow passage (14C) constituting the outer peripheral surface washing passage (14) is provided in a position closer to the backside into the annular clearance (20) by a length dimension (L1) than a front end surface (17A) of a front ring section (17) constituting the shaping air ring (15). Further, the outflow opening (14C1) opens to the annular clearance (20) in an angle (α1) that is an acute angle to the atomizing head outer peripheral surface (13).

Abstract:
Provided is an inkjet recording device for performing print control by increasing or decreasing the number of adjustment ink particles, which are used according to the speed of the object being printed even when the movement speed of the object being printed is increasing or decreasing and which are uncharged particles carrying a fixed electrical charge that takes electrostatic bonding into consideration. The present invention is an inkjet recording device provided with an ink container for holding ink that is to be printed on the object being printed, a nozzle that is connected to the ink container and discharges the ink, a charging electrode for charging specified ink that has been discharged from the nozzle, a deflecting electrode for deflecting the ink charged by said charging electrode, a gutter for collecting the ink that is not used for printing, and a control unit for controlling the printing. The inkjet recording device is characterized in that the control unit performs control so that ink particles which are not used for printing and are adjacent to ink particles that are used for printing are charged by the charging electrode.
Abstract:
A method of stripping, prepping and coating a surface includes first stripping the exiting coating from a surface, using continuous or pulsed fluid jet, followed by prepping the surface by the same fluid jet. The method also provides entraining particles into a fluid stream, if desired to generate a particle-entrained fluid stream that is directed at the surface to be stripped and prepped. The particles act as abrasive particles for prepping the surface to a prescribed surface roughness required for subsequent application of a coating to the surface. The method then entails coating the surface by electrically charging particles having the same chemical composition as the particles used to prep the surface. Finally, a charged-particle-entrained fluid stream is directed at high speed at the charged surface to coat the surface. The particles form both mechanical and electronic bonds with the surface.
Abstract:
There is disclosed an apparatus for spraying and patterning, using an electrostatic force, includes a nozzle to which a voltage is applied to exhaust ink, a droplet circulation chamber provided in one end of the nozzle, with a hole provided in one end to spray the ink exhausted from the nozzle based on a particle size of the droplet and to temporarily collect the not-sprayed ink, and a substrate for impacting the ink sprayed from the hole thereon by forming an electric field between the nozzle and the substrate.
Abstract:
A gantry tower spraying system with a cartridge/receptacle assembly includes a gantry and a spray assembly coupled to the gantry to allow for translational movement of the spray assembly along the gantry. The spray assembly includes a receptacle for receiving a cartridge containing a cosmetic liquid for skin treatment, and a spray nozzle coupled to the receptacle for receiving the cosmetic liquid and dispensing the cosmetic liquid in a spray. The receptacle has an inner surface of a size and shape to generally conform to a size and shape of a portion of an outer surface of the cartridge. The spraying system can further be provided with an oscillation mechanism adapted to cause oscillation of the spray nozzle. The bottle can be provided with a keying mechanism for engaging a corresponding key structure of the receptacle.
