  • Publication number: 20090288598
    Abstract: A supply system for a chambered doctor blade assembly makes possible the sequential use of water-based and non-water-based coating materials through automated functions programmed in a PLC that controls the system. A pair of pneumatically driven diaphragm pumps serve as supply pump and return pump between the doctor blade chamber and a coating reservoir A PLC controls the pulse rate of pneumatic pressure to the pumps to control the rate of flow of the coating material into, and out of the doctor blade chamber. An ultrasonic sensor mounted detects the liquid level in the trough collection area. The PLC is programmed to modify the pulse rate of the supply pump and return pump to maintain the liquid level in the trough collection area above the drain thereof and below the maximum tolerance.

  • Publication number: 20090004380
    Abstract: The invention relates to a method and a device for applying for a flowable material, especially a particulate material, in individual superimposed layers across a support (50), the flowable material being first filled from a stationary feed station (10) into a storage container (24) of an application device. In the application device (30), which travels back and forth across the support, the flowable material is distributed inside the storage container across the entire length of the device and is then metered through a slot into a metering shaft in such a manner that the filling level in the metering shaft remains constant during application of the flowable material from the metering shaft onto the support.

  • Patent number: 7014884
    Abstract: A coated film forming method is capable of readily forming a coated film of a thermoplastic material on a coated region of an inner peripheral surface of a cylinder. A nozzle, through which a molten paste of a thermoplastic material kept molten is discharged, is disposed toward an inner peripheral surface of a cylinder. The nozzle is moved along a rotational central line of the cylinder while rotating the cylinder and discharging the molten paste from the nozzle. Centrifugal force acting on the cylinder being rotated leads to spreading of the molten paste applied to the inner peripheral surface of the cylinder. Viscosity of the molten paste, a rotational speed of the cylinder and a speed of movement of the nozzle are set so as to keep the molten paste discharged from the nozzle from being scattered to a region other than the coated region.

    Abstract: The present invention provides a providing device capable of using a solution within a tank effectively than ever as preventing an air bubble from mixing in the solution to be provided to an applying device. In providing devices and for leading a coloring sensitive matter from any one of a plurality of pressure tanks to an applying device via a predetermined flow path, middle tanks are provided every for each of pressure tanks on the way of a flow path connecting each of the plurality of pressure tanks and the applying device. A sensor detects whether an amount of a solution stored in respective middle tanks is not less than a predetermined lower limit value or not. Then, a signal in response to its result of the detection is outputted to a system controlling device. On the basis of this output signal, it is discriminated whether the amount of the solution in the middle tank is not less than the lower limit value or not.

  • Patent number: 6923023
    Abstract: Methods and apparatuses estimate and control optical fiber primary coating diameter for wet-on-wet optical fiber manufacturing. The primary coating diameter for a particular length of optical fiber is calculated based upon a measurement of the weight of primary and/or secondary coating material consumed during optical fiber manufacturing. Control of the primary coating diameter is effected by a coating controller which can increase or decrease the primary coating diameter through control of glass temperature, coating viscosity and/or other parameters during wet-on-wet fiber manufacture.

  • Patent number: 6881267
    Abstract: A photoresist supply apparatus is provided. 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.
