Thus, the entire color coating system can travel to any appropriate location in the fiber manufacturing facility, e.g., at any one of a number of draw towers. Such portability allows many different colors to be used at the same draw tower much more easily than conventional arrangements, which typically only have one color line per draw tower. The method includes providing an optical fiber, controllably delivering color concentrate with a coating material to a coating die, coating the optical fiber with the coating die, and curing the coated fiber.

The photoresist supply apparatus includes a lower photoresist sensor and an upper photoresist sensor respectively installed near the bottom and the top of a trap tank to detect a photoresist in the trap tank. A drain line is connected to an upper side of the trap tank to release air. A photoresist-blocking valve is installed at the drain line, the photoresist-blocking valve structured to be opened to release air or closed to prevent photoresist loss according to signals detected by the lower photoresist sensor and the upper photoresist sensor. While the photoresist is supplied into the trap tank, the photoresist-blocking valve is opened to release air. After the photoresist supply into the trap tank is completed, the photoresist-blocking valve is closed to prevent the loss of a large amount of the photoresist through the drain line.

  • Patent number: 6790282
    Abstract: A machine for automatically applying lane dressing travels up and down the lane to apply dressing according to a certain predetermined and preselected pattern. A single dispensing head travels back and forth across the lane as the machine moves linearly along the lane so that dressing is transferred to a buffer brush that engages the lane surface and applies the dressing thereto. The oil pattern is determined by actuation and deactuation of the dispensing head as it traverses the lane, such control of the head being provided by a special pattern control device in the nature of a cylindrical pattern tube that extends alongside the path of travel of the dispensing head. A sensor on the dispensing head detects pattern structure on the control device to responsively actuate and deactuate the head. In a preferred form, such structure takes the form of a series of metallic strips extending parallel to the path of travel of the dispensing head and spaced circumferentially around the periphery of the pattern tube.

  • Publication number: 20040094089
    Abstract: The present invention is a film forming unit for discharging a coating solution from a coating solution discharge nozzle toward a substrate to form a layer on a surface of the substrate, which has a supply flow path for supplying a cleaning fluid to a discharge flow path continuing to a discharging port of the coating solution discharge nozzle. When the cleaning fluid is positively supplied directly to the discharge flow path of the coating solution discharge nozzle, the supply pressure of the cleaning fluid as well as the capability of cleaning is added. Therefore, further effective cleaning is attained in compare with the conventional case where a coating solution discharge nozzle is simply dipped into a cleaning fluid. In consequence, even when the discharging port of the nozzle is minute, it is possible to perfectly remove the contamination. This allows the discharge pressure to remain constant so as to form a uniform coating layer on the substrate.

  • Patent number: 6726773
    Abstract: A method is disclosed for providing a steady transition state for an integral pneumatic dispensing system that is related to a robot. The method dispenses a single material using a pneumatic dispensing system having a single output including first and second shotmeters having first and second meters, first and second encoders and first and second pressure transducers. The method includes the step of loading the first shotmeter with the material. Once loaded, a pressure is applied to the material. The material is then dispensed out of the first shotmeter by forcing the material through the single output. Once the material in the first shotmeter is dispensed to a predetermined volume, the method begins to transition the flow of material from the first shotmeter to the second shotmeter. The transition includes the control of the volume being dispensed and the pressure applied to the material.

  • Patent number: 6712906
    Abstract: An apparatus for controlling a speed of a motor of a metering pump providing pressurized fluid at a dispensing gun. The dispensing gun is opened and closed to dispense fluid onto a substrate being carried by a conveyor past the dispensing gun. The apparatus has a pressure control producing first motor speed signals as a function of changing speeds of the conveyor and changing fluid pressures in the dispensing gun when the dispensing gun is open. A flow control produces second motor speed signals as a function of the changing speeds of the conveyor. During changes in conveyor velocity, a motor speed control provides the first motor speed signal to the pump motor which operates the motor at speeds causing the pump to provide fluid to the dispensing gun at pressures changing at a rate tracking a rate of change of the speed of the conveyor.

  • Patent number: 6660091
    Abstract: A liquid output portion is arranged above and moves relative to a semiconductor substrate with determined film formation and non-film-formation regions. The liquid output portion continuously outputs a liquid in a constant amount to the substrate. Below the liquid output portion is a liquid shut-out-portion. A liquid controlled to spread in a constant amount is continuously output from the liquid output nozzle to the substrate. While the nozzle and the substrate relatively move, the liquid is supplied to a first region, and the liquid is supplied to a second region in such a way that the liquid supplied and spread in the second region is in contact with the liquid supplied and spread in the first region. Where projections and depressions are formed on the surface of the substrate, an amount of the liquid supplied varies depending upon the ratio between the projections and depressions.

    Abstract: A system for controlled dispensing of a material onto an elongated window component. A nozzle dispenses the material into contact with a surface of the elongated window component at a delivery site located along a path of travel of the elongated window component. A conveyer moves the elongated window component along the path of travel relative to the nozzle at a controlled speed. A metering pump delivers controlled amounts of the material to the nozzle. A pressurized bulk supply delivers the material to an inlet to the metering pump. A controller regulates the speed of the metering pump to control the flow rate of the material dispensed by the nozzle.

  • Patent number: 6626996
    Abstract: A pizza sauce dispenser simultaneously dispenses and spreads a precisely controlled amount of sauce onto a pizza dough base without manually handling the sauce or the dough during operation. The dispenser includes a selectively rotatable disc and an arm that selectively extends over the disc. At lease one nozzle is supported by the arm and selectively dispenses the sauce onto the dough. A control mechanism controls: (1) a selected rate and direction of disc rotation; (2) a selected pivot rate and direction of the arm; and/or (3) a selected rate of dispensing sauce through the nozzle. In use, with pizza dough placed on the disc, the disc is rotated and the arm pivoted over the dough so that the nozzle traverses a path from the outside edge of the dough to the center of the dough or vice versa. Sauce thus is deposited in a spiral or other desirable pattern.
