  • Publication number: 20150099121
    Abstract: (Problem) In conventional method for producing artificial graphite, in order to obtain a product having excellent crystallinity, it was necessary to mold a filler and a binder and then repeat impregnation, carbonization and graphitization, and since carbonization and graphitization proceeded by a solid phase reaction, a period of time of as long as 2 to 3 months was required for the production and cost was high and further, a large size structure in the shape of column and cylinder could not be produced. In addition, nanocarbon materials such as carbon nanotube, carbon nanofiber and carbon nanohorn could not be produced.

  • Publication number: 20150024208
    Abstract: (Problem) A porous carbon material having excellent graphite crystallinity, good carrier mobility and proper porosity, a porous carbon material having edges of carbon hexagonal planes located on outer surfaces of particle and structure, and flaky graphite being similar to graphene are produced. (Means to Solve) By subjecting a carbon material, in which a closed-pore-ratio and an amount of remaining hydrogen in the material are set to be within a proper range, to hot isostatic pressing treatment, a vapor phase growth reaction of graphite is generated in closed pores as nuclei using hydrogen and hydrocarbon generated from the carbon material, thereby producing a large amount of targeted porous carbon material at low cost. Flaky graphite being similar to graphene is produced by applying physical impact to the obtained porous carbon material or by generating a graphite intercalation compound using the porous carbon material as a host and then quickly heating the compound.

  • Publication number: 20140315460
    Abstract: The present invention relates to a method for producing a carbon fiber that can be suitably used as a transparent conductive material for forming transparent flexible conductive films and the like, more particularly, to a method for producing a carbon fiber having an outermost surface composed of edges of graphenes, and to a carbon fiber produced by the production method. The production method comprises a step of pre-baking a fiber of an organic compound so as to contain remaining hydrogen, and a step of putting the pre-baked fiber of the organic compound in a closed vessel made of a heat resistant material and subjecting the pre-baked fiber together with the vessel to hot isostatic pressing treatment using a compressed gas atmosphere, wherein a maximum ultimate temperature in the hot isostatic pressing treatment is 1000 to 2000° C.

  • Patent number: 8657033
    Abstract: In a grinder, a terminal plate is projectingly provided on an upper surface of a controller. A connection portion, which accommodates a female terminal and includes a slit into which the terminal plate enters, is projectingly provided on a lower surface of a main body portion of a switch block. At the time of assembling of the switch block and the controller, the terminal plate that enters into the connection portion from the slit is inserted into and connected to the female terminal. First and second projections that cover a formation surface of the slit in the connection portion when the connection portion is inserted with and connected to the terminal plate are formed on the upper surface of the controller.

  • Patent number: 8618700
    Abstract: A head of an output shaft of a linear actuator is modified so as to absorb vibrations that may be transmitted between the output shaft and a moving object. A linear actuator has an output shaft with a leading end to which a head is fixed. The head has an O-ring that is fitted thereto, and a part of the O-ring outwardly projects from the head. The O-ring is made of rubber that is softer than the material of the head. The head is contained in a containing space in an attachment, and in this condition, the O-ring contacts an inner circumferential surface of the containing space by deforming.
