  • Patent number: 7306503
    Abstract: Evaporation and condensation of carbon is effected by arc discharge between an anode formed of a carbon electrode and a cathode disposed facing the carbon electrode 2 in an inert gas atmosphere, and at the same time, the generated carbon nanotubes are dispersed into an inert gas and transported along with the inert gas through a transporting tube, and a jet of the inert gas containing the carbon nanotubes is emitted from a nozzle, thereby forming carbon nanotubes on a target substrate. This provides a carbon nanotube manufacturing method wherein carbon nanotubes are generated with a simple process, and the CNT patterning process is simplified by forming a carbon nanotube film on a substrate, thereby reducing costs.

  • Patent number: 7131886
    Abstract: A method of producing a fiber, comprising the steps of introducing catalytic particles originally formed in a particle-forming chamber into an arraying chamber together with a carrier gas, to cause the catalytic particles to become arranged on a substrate disposed in the arraying chamber. A next step includes growing fibers, each including carbon as a major component, based on the catalytic particles arranged on the substrate. The fibers grow by heating the catalytic particles arranged on the substrate in an atmosphere containing carbon.

  • Patent number: 6500352
    Abstract: An electrode plate is formed by a substrate and a plurality of patterned electrodes formed on the substrate. Each patterned electrode has a laminate structure including a first layer of nickel metal formed on the substrate and a second layer of copper formed thereon. The electrode plate may be prepared by a process including a step of etching such a multi-layer metal electrode-forming film formed on a substrate by spraying an etchant downwardly and uniformly onto the substrate while rotating the substrate at a rotation speed sufficient to allow quick liberation of the etchant from the substrate. The metal electrodes can be formed with good adhesion onto the substrate and with good width and thickness accuracy. By incorporating the electrode plate as a pair of substrates sandwiching a liquid crystal, a liquid crystal device free from transmission delay and rounding of voltage waveforms can be provided.
