  • Patent number: 10632492
    Abstract: A defect may occur in which as the amount of fluid discharged by a fluid discharge device decreases, a mask is not filled with the fluid even when the fluid is discharged. In order to fill a workpiece with the fluid, it is necessary to replace air in the workpiece corresponding to a discharge part with the fluid. The air in the workpiece is removed in advance, thereby filling the workpiece with the discharged fluid. A fluid discharge device in which, at one end of a discharge head, a suction port for sucking air in the mask on the workpiece, and a fluid discharge device having a discharge nozzle formed thereon for discharging the fluid are formed is used.

  • Patent number: 10625290
    Abstract: A protective collar for temporarily protecting an item from paint on a surface that is being painted. The protective collar is formed as a band having a convex surface and a concave surface. The band has a uniform thickness between the convex surface and the concave surface in the primary areas that are not tapered. The band embodies a spring bias that biases the band into a circular configuration. The first end and the second end of the band are tapered. Additionally, the band is tapered along its length adjacent a first long edge. This causes the first long edge to be thinner than the opposite second long edge. The tapered regions minimize the footprint of the spring collar on a surface.

  • Patent number: 10586742
    Abstract: An ink jet process is used to deposit a material layer to a desired thickness. Layout data is converted to per-cell grayscale values, each representing ink volume to be locally delivered. The grayscale values are used to generate a halftone pattern to deliver variable ink volume (and thickness) to the substrate. The halftoning provides for a relatively continuous layer (e.g., without unintended gaps or holes) while providing for variable volume and, thus, contributes to variable ink/material buildup to achieve desired thickness. The ink is jetted as liquid or aerosol that suspends material used to form the material layer, for example, an organic material used to form an encapsulation layer for a flat panel device. The deposited layer is then cured or otherwise finished to complete the process.

  • Patent number: 10576492
    Abstract: A surface treating apparatus that suppresses occurrence of defects is provided. A treatment solution is accumulated in a tank 15 through a treatment solution collecting port/air discharging port 13 in a lower portion of a body 4. An air heated by the treatment solution flows toward an upper portion (portion without the treatment solution) of the tank 15 via the treatment solution collecting port/air discharging port 13 in the lower portion of the body 4, and is discharged via an exhaust duct 17. In this way, the air that is heated and tends to flow upward in the body 4 is discharged from the lower portion thereof and is replaced with an external air from the upper portion thereof. Accordingly, the air in the body 4 can be maintained at a uniform temperature. Thus, the treatment solution that reaches a lower portion of a substrate 54 from an upper portion thereof can be maintained at a uniform temperature.

  • Patent number: 10569299
    Abstract: A system that reduces the amount of water that enters a process chamber via a movable shaft is disclosed. The surface of the shaft is made hydrophobic. Any water droplets that are collected on the hydrophobic shaft are disposed at a high contact angle, making it more likely that these water droplets fall from the shaft. Further, any water that enters the process chamber is more readily removed from the shaft due to the lower energy of liberation. Reducing the amount of water in a process chamber may improve the lifetime of the components in the process chamber and may improve the yield of the workpieces being processed. This may be especially relevant when process gasses that contain halogens are employed.

  • Patent number: 10573900
    Abstract: An orifice plate having orifice openings is interposed between a roller body and a side plate. In a closed region of an outer peripheral surface of the roller body which is covered with a base material, the base material is held on the outer peripheral surface of the roller body under suction by a negative pressure developed in suction holes. In an open region of the outer peripheral surface which is not covered with the base material, the sucking of a gas from an exterior space into the roller body is suppressed because it is difficult for the gas to pass through the orifice openings. This suppresses a reduction in sucking force in the closed region due to the entry of the gas from the open region. The roller body, the orifice plate and the side plate rotate as a unit. This suppresses deterioration of the members due to the slidable movement thereof.
