| 20100032653 | Carbon Nanotube Electric Field Effect Transistor and Process for Producing the Same - This invention provides a process for producing a carbon nanotube electric field effect transistor that can improve yield in channel preparation. Carbon nanotubes dispersed in a mixed acid composed of sulfuric acid and nitric acid are subjected to radical treatment with aqueous hydrogen peroxide to cut the carbon nanotubes and thus to provide carboxyl-introduced carbon nanotube fragments. The carbon nanotube fragments are attached, through a covalent bond and/or an electrostatic bond, to a site, where a source electrode is to be formed, and a site where a drain electrode is to be formed, in a substrate with a functional group, to be attached to a carboxyl group, introduced thereinto. The carbon nanotube fragments attached to the substrate are attached to carbon nanotubes as channels through n-n interaction to fix the carbon nanotubes as channels to the substrate. | 02-11-2010 |

| 20080283875 | FIELD EFFECT TRANSISTOR, BIOSENSOR PROVIDED WITH IT, AND DETECTING METHOD - A high-sensitivity field effect transistor using as a channel ultrafine fiber elements such as carbon nanotube, and a biosensor using it. The field effect transistor comprises a substrate, a source electrode and a drain electrode arranged on the substrate, a channel for electrically connecting the source electrode with the drain electrode, and a gate electrode causing polarization due to the movement of free electrons in the substrate. For example, the substrate has a support substrate consisting of semiconductor or metal, a first insulating film formed on a first surface of the support substrate, and a second insulating film formed on a second surface of the support substrate, the source electrode, the drain electrode, and the channel arranged on the first insulating film, the gate electrode disposed on the second insulating film. | 11-20-2008 |

| 20090126548 | Punch press - To provide a punch press which can effectively suppress vibration even when punching operation is performed at high speed. The punch press according to the present invention includes a press drive source, a drive transmitting mechanism which transmits power from the press drive source to a punch tool, and the punch tool connected to the drive transmitting mechanism, wherein at least a part of the drive transmitting mechanism is made of a carbon fiber material. Accordingly, the weight of the drive transmitting mechanism is reduced, and thus it is possible to reduce the force of inertia generated by the mass transfer of the drive transmitting mechanism and effectively suppress vibration, even when punching operation is performed at high-speed. When the power transmitting mechanism is made lighter in such manner, there is the effect of reducing the noise during the punching operation and reducing the power consumed during the punching operation. | 05-21-2009 |
