  • Patent number: 9073045
    Abstract: The method for producing carbon nanotubes employs a carbon source that contains carbon and is decomposed when heated and a catalyst on a support that serves as a catalyst for production of carbon nanotubes from the carbon source. The method includes a catalyst loading step in which the catalyst starting material is distributed over the support to load the catalyst onto the support, a synthesis step in which the carbon nanotubes are synthesized on the support, and a separating step in which a separating gas stream is distributed over the support to separate the carbon nanotubes from the support, wherein the catalyst loading step, the synthesis step and the separating step are carried out while keeping the support in a heated state and switching supply of the catalyst starting material, the carbon source and the separating gas stream.

  • Patent number: 8518363
    Abstract: [Problems to be Solved]There is provided a method for production of a carbon nanotube, which allows for production of the carbon nanotube in a large scale and at a low cost. [Solution] The temperature of a catalyst loaded on a support is raised by heating the support and a raw material gas containing a carbon source is supplied on the catalyst to synthesize the carbon nanotube. The synthesized carbon nanotube is recovered, and after the recovery, the catalyst is subjected to a regeneration treatment to repeatedly utilize the support. Since the catalyst deteriorates, the catalyst is regenerated periodically or nonperiodically during the production. The regeneration treatment of the catalyst involves an oxidation treatment of the catalyst. Further, after the oxidation treatment, a reducing gas is fed to and brought into contact with the catalyst surface to reduce the catalyst. As the support, a honeycomb is used.

  • Patent number: 7455731
    Abstract: A polycrystalline silicon rod according to present invention has a structure for hanging of polycrystalline silicon rods to each other end-to-end, so that the efficiency of melting polycrystalline silicon can be increased considerably. A polycrystalline silicon rod obtained by entirely or partially removing a peripheral portion from the rod to leave a central portion, and processing the central portion, preferably, the peripheral portion is removed by grinding in an amount corresponding to 10 to 60% of the diameter of the rod, and then subjected to groove-forming processing. This makes annealing unnecessary.

  • Patent number: 7394243
    Abstract: A proximity sensor 717 comprising a combination of an arbitrarily selected one of a plurality of types of detection end modules 707, a plurality of types of output circuit modules 709 and a plurality of types of outer shell cases 711. The detection end module 707 includes an integrated arrangement having a detection coil assembly (705, 701, 702) with the detection characteristic self-completed by a mask conductor 700 for reducing the conductor detection sensitivity in a specific peripheral area where the outer shell case is assumed to exist, and a detection circuit assembly (703) with the coil of the detection coil assembly as a resonance circuit element. The characteristics of the proximity sensor are completely adjusted before shipment. As a result, the adjustment of the characteristics which otherwise might be required each time is eliminated even in the case of the combination with an outer shell case of a different material.
