  • Patent number: 10354894
    Abstract: A semiconductor wafer held by a holder within a chamber is irradiated and heated with halogen light emitted from multiple halogen lamps. Cylindrical outer and inner louvers made of opaque quartz are provided between the halogen lamps and the semiconductor wafer. A reflector is provided in an area of tube walls of the halogen lamps that faces the spacing between the inner wall surface of the outer louver and the outer wall surface of the inner louver. The spacing between the two louvers is located immediately below and faces the peripheral portion of the semiconductor wafer. Thus, the illuminance of light that reaches the peripheral portion of the semiconductor wafer where a temperature drop is likely to occur will be higher than the illuminance of light that travels toward the central portion from the halogen lamps. This configuration will help make uniform the in-plane temperature distribution of the semiconductor wafer.

Then the display window is rotated around said axis of symmetry, and at the same time, said axis is tilted to a horizontal position. The suspension is thereby distributed on the inner side of the display window. An excess of suspension is collected during the rotation in four collection cups (8) arranged at the comers (7) of the display window, whence it is drained off to a central collection cup (10). Finally, the part of the suspension which remains on the display window is dried by infrared radiation (9). As the suspension is drained from the four collection cups to the central collection cup during the rotation, there is no risk that the suspension may drip from the cups onto the display window.

  • Patent number: 6780366
    Abstract: The invention provides mandrels for producing elastomeric components such as mammary implants. Specifically, the invention provides mandrels that include a mold, a shaft attached to the mold, and a drip retainer attached to the shaft. The drip retainers disclosed herein are configured to catch and contain fluids (e.g., elastomeric compounds dispersed in solvents) that run and/or drip off the mold and shaft, and to retain such fluids when the dipping mandrel is inverted. The invention also provides drip retainers that can catch and contain fluids (e.g., elastomeric compounds dispersed in solvents) when attached to a dipping mandrel, and can retain the fluids upon inversion of the dipping mandrel.

  • Patent number: 6767403
    Abstract: A spin bowl includes a base and a sidewall that extends from the base. The base has an upper portion for supporting a substrate in a horizontal plane and a lower portion that intersects with the sidewall. The lower portion of the base has a plurality of drain holes formed therein proximate to the sidewall. Each of the plurality of drain holes is configured to trap fluid therein during spinning of the spin bowl to thereby form a fluid seal that prevents air from flowing therethrough. In one embodiment, each of the drain holes is V-shaped. In another embodiment, the fluid seal is formed by the intersection of a straight drain hole with an external fluid catch area. An apparatus and method for spin coating a film over a substrate also are described.

  • Patent number: 6740164
    Abstract: Plating apparatus and plating method that can plate more uniformly on a processing surface of a workpiece are provided. The plating apparatus is comprised of a plating solution bathe which is provided with a first electrode held in a state soaked in a plating solution; a workpiece holding mechanism which holds a workpiece to contact its processing surface to the plating solution; and a contact member, disposed in the workpiece holding mechanism, that electrically contacts with the circumferential edge of the workpiece so to form a conductive layer on the workpiece surface as a second electrode. The contact member is divided along the circumferential direction of the workpiece with which they are electrically contacted. Thus, even if the contact resistance between each section of the contact member with the workpiece is variable, it is possible to adjust the plating electric current for each section of the contact member.

    Abstract: This invention relates to methods and apparatus for making coated articles with one or more layers by dip, spray or flow coating. In one aspect, this invention relates to an apparatus and method for making coated containers, preferably comprising polyethylene terephthalate, from coated preforms. In preferred embodiments, the apparatus and method permit the coated container or preform to be made in an energy-efficient manner that reduces the danger of coating damage and thus increases the efficacy of the final container.

  • Patent number: 6718127
    Abstract: A heating device of the light irradiation type in which uniform illuminance can be obtained without placing a single end lamp in the middle of the light source part is achieved providing a light source part in which circular lamps are arranged concentrically to one another with a mirror in the center of the circular lamps. The mirror is convex toward the workpiece and reflects the light emitted from the innermost circular lamp located closest to the center area so that, without placing a single end lamp in the middle area, the reduction of illuminance in the middle area of the irradiated surface is reduced. Furthermore, the reflector can be made conical, and in this way, the light from the lamps can be emitted with high efficiency onto the workpiece surface.
