  • Publication number: 20160167968
    Abstract: A nitrogen-containing carbon material to the present invention comprises a carbon material having a carbon skeleton formed of carbon atoms and nitrogen atoms introduced into the carbon material, wherein part of carbon atoms in the carbon skeleton are substituted with nitrogen atoms. The nitrogen-containing carbon material according to the present invention can be produced by a production method including the steps of bringing the carbon material into contact with a first treatment gas containing a fluorine-containing gas to subject a surface of the carbon material to a fluorination treatment; and bringing the carbon material after being subjected to the fluorination treatment into contact with a second treatment gas containing a nitrogen-containing gas with heating to perform a nitriding treatment.

  • Publication number: 20080150659
    Abstract: A relay device using a conductive fluid and having excellent switching response is provided. This relay device mainly comprises a laminate having an interior space, and formed by bonding a semiconductor substrate to an insulating substrate, at least two contacts exposed to the interior space, a diaphragm portion facing the interior space, a conductive fluid sealed in the interior space, and an actuator for elastically deforming the diaphragm portion. By forming the diaphragm portion on the semiconductor substrate, it is possible to reduce a driving force of the actuator needed to elastically deform the diaphragm portion, and obtain a volume change of the interior space with good response. This volume change causes a positional displacement of the conductive fluid in the interior space, thereby forming a conductive state or a non-conductive sate between the contacts.
