  • 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: 6800327
    Abstract: A method and an apparatus for coating metal strip, particularly cold-rolled steel strip, with a coating metal which is in the molten state. The metal strip is heated and annealed in a heating furnace and subsequently the required strip temperature and surface properties are adjusted in a cooling zone. The strip is conducted through a coating container and, following the coating container in strip pulling direction, the coating metal thickness and the solidification process are controlled by a gas-operated stripping device. The operating gas for the stripping device is preheated in a partial area of the cooling zone of the heating furnace.

  • 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.

  • Patent number: 6719845
    Abstract: The present invention relates to an improved doctor blade and bedplate apparatus wherein there is a recess in the bedplate from some position upstream of the doctor blade to some position downstream of the doctor blade. This recess or gap in the area of the bedplate under the doctor blade allows one to form an even or uniform coating on the back of a web of material. This is particularly helpful in forming uniform coatings on the back of a greige good which has face fibers of varying lengths. The present invention also relates to an improved process for preparing a relatively uniform coating on the back of a web of material.

  • Patent number: 6572703
    Abstract: An apparatus for forming and finishing a continuous fabric web in a single operation. The apparatus includes a fabric web forming station for forming a continuous fabric web and a finishing station downstream from the fabric web forming station for receiving the continuous fabric web from the fabric web forming station and for providing a finishing treatment to the continuous fabric web. In the preferred embodiment, the finishing station includes a substantially excess-free applicator which helps to prevent thick spots in the coated fabric web which may occur when a coating applicator is stopped and restarted. In the preferred embodiment, the finishing station includes a curing station downstream from the applicator. The curing station may include both a drying station and a heat set station downstream from the drying station. The operating temperatures of the drying and heat set stations are controlled to minimize the amount of air having VOCs to be treated before being discharged into the atmosphere.
