Abstract: Techniques for a cover layer with uniform thickness are disclosed. The cover layer is formed with a type of material, such as glue, in hardened form. In one embodiment, a certain amount of the material in liquid form is dispensed onto a dispensing structure. After the dispensing structure is engaged to hold a disc, the dispensing structure and the disc as a whole unit to be rotated at a predefined speed. The dispensed material on the dispensing structure is dispersed evenly onto the surface of the disc as result of the centrifugal force. A curing process (e.g., using UV lighting) is then engaged to harden the material near the edge of the disc to prevent the dispersed material from shrinking.

Abstract: For use in a rotational casting machine used for coating a rotating body with elastomer, such as polyurethane, there is provided a nozzle used for dispensing the liquid polyurethane onto the rotating body to be coated. The nozzle of the invention has a plurality of liquid-flow interior discharge-passageways each of which has an inlet connected to a sub-branch tube, which sub-branch tube is, in turn, is fluidly connected to a main branch that, in turn, is connected to a main inlet-passageway having the inlet that is directly connected to mixing head. Each discharge-passageway, or exit-passageway, changes in cross-sectional shape along the longitudinal axis thereof from its inlet to its outlet such that the cross-sectional area from the inlet to the outlet thereof gradually and minimally increases, whereby at least substantial laminar flow of the liquid is achieved with the concomitant reduced dwell-time of the liquid therein, in order to reduce in-nozzle reaction and subsequent clogging of the nozzle.

Abstract: A resin block has a treating solution channel extending between and opening at front and back surfaces thereof. Heat conductive members are face-bonded to the front and back surfaces of the resin block, respectively, for closing the channel. Consequently, no air is present between the resin block and heat conduction members, thereby improving the efficiency of heat exchange. A nozzle of simple construction is realized only by face-bonding the two heat conductive members to the open front and rear surfaces of the resin block. Temperature control plates hold the heat conductive members along with the resin block to effect a temperature control, whereby the temperature of a treating solution in the treating solution channel is controlled effectively through the heat conductive members. The treating solution adjusted to a desired temperature is delivered from a discharge opening to a substrate for performing substrate treatment with high accuracy.

Abstract: An apparatus and method for electrostatic spray deposition of small targets, such as medical devices like stents. The apparatus includes a target holder which applies a first electrical potential to the target, and an electrostatic dispensing nozzle which applies a second potential sufficient to attract the coating fluid from the nozzle toward the target. Because the entire dispensing nozzle is conductive, the coating fluid may receive a greater charge than may be obtained with internal electrode-type nozzles. Electrostatic attraction of the coating fluid to the target is enhanced by the combination of higher charge density imparted to the coating fluid by the conductive nozzle, and application of a momentary voltage spike to the target to provide consistent conductivity between the target and its holder, thereby ensuring the target is presents the full first potential applied to the holder. The voltage spike may also be used independently of the conductive nozzle.

Abstract: A rotatable vacuum chamber receives an optical connector having an output face on which an optical gel is applied substantially without entrapped air. Opposite the output face is placed a gel dispenser with its opened nozzle pointing towards the output face. Uncured gel components contained in the dispenser are outgased prior to application of the gel on the output face while a vacuum is maintained in the chamber. Outgasing takes place at a first chamber orientation with the nozzle pointing upwards through which the outgasing air ventilates. The gel is applied at a second chamber orientation where the output face is horizontal and upwards pointing. Immediately following the gel application, the vacuum is unmade to prevent cooking of the mixed and uncured gel. A glass plate is then pressed against the applied fluid gel.
