When a long wire type MMO anode is manufactured, a uniform coating layer is formed thanks to the use of reel-to-reel continuous coating and heat treatment under uniform conditions, thus increasing durability and quality of the long wire type MMO anode. The exposure time of the metal substrate to the outside between the processes is minimized, and productivity is increased, thus decreasing the manufacturing cost to result in high product competitiveness.

  • Patent number: 7980195
    Abstract: A transistor is formed by applying modifier coatings to source and drain contacts and/or to the channel region between those contacts. The modifier coatings are selected to adjust the surface energy pattern in the source/drain/channel region such that semiconductor printing fluid is not drawn away from the channel region. For example, the modifier coatings for the contacts can be selected to have substantially the same surface energy as the modifier coating for the channel region. Semiconductor printing fluid deposited on the channel region therefore settles in place (due to the lack of a surface energy differential) and forms a relatively thick active semiconductor region between the contacts. Alternatively, the modifier coatings can be selected to have lower surface energies than the modifier coating in the channel region, which actually causes semiconductor printing fluid to be drawn towards the channel region.

  • Patent number: 6932869
    Abstract: The present invention provides an improved method and apparatus for curing coatings on optical fibers, without creating additional heat and compromising the manufacturing speed of optical fibers. The present invention uses at least one ultrasonic transducer coupled to a component of the optical fiber draw tower, such as the coating die, curing stage device or sheath, to emit ultrasound to the coating of the fiber. The use of ultrasound with current coating cure techniques, such as UV radiation curing, aids in accelerating the coating cure process through the effects of sonolysis, allowing an increase in current manufacturing speeds of optical fibers.

  • Patent number: 6730165
    Abstract: A device for impregnating a paper web with a molten polymer to produce a paper with improved resistance to oil and grease are provided. The device includes, as part of an on-machine process, an ordinary paper web composed of cellulose or synthetic fibers, a polymer applicator, a hot reel, and a winding reel. The web, which is created through a series of processes located upstream of the subject invention, first encounters the polymer applicator, which deposits a quantity of molten polymer onto the surface of the web. The web is next transferred to a hot reel, which maintains the temperature of the molten polymer above its melting point and thereby facilitates wicking of the molten polymer into the web. After the web passes the hot reel, it is wound onto a winding reel, where additional wicking occurs until the molten polymer cools to a temperature below its melting point.
