  • Publication number: 20190047868
    Abstract: Provided are an sp2 carbon-containing composition that is highly conductive and that excels in the stability of conductivity over time, a method of manufacturing the sp2 carbon-containing composition, and a method of peeling graphite to obtain a graphene-containing composition. Further provided are a graphene quantum dot-containing composition and a method of manufacturing the graphene quantum dot-containing composition that provides an improvement in the productivity and the manufacturing cost. A method of manufacturing an sp2 carbon-containing composition according to the present disclosure includes a contact step of bringing a two-coordinate boron cation salt into contact with an sp2 carbon. Preferable examples of the two-coordinate boron cation include one expressed by the following formula (1).

  • Publication number: 20190032670
    Abstract: A centrifugal compression test device includes a flow path forming section and an inlet space forming section. The flow path forming section forms an introduction flow path, an inlet flow path, and an interstage inflow path. The introduction flow path guides a fluid from the outside toward the inside in the radial direction. The inlet flow path is connected to the introduction flow path. The interstage inflow path extends from the outside toward the inside in the radial direction and is connected to the inlet flow path. The inlet space forming section is formed an annular shape having an introduction opening section through which a fluid is introduced from a part in the circumferential direction and the outside in the radial direction at the first side of the introduction flow path. Further, a front end of the introduction flow path is connected to the inlet space forming section.

  • Patent number: 9825232
    Abstract: The present invention provides a high-performance, highly homogeneous, highly stable electronic device by forming an extremely uniform interface between an insulator and an organic semiconductor, as well as an electronic apparatus using the same. The present invention relates to an electronic device which contains, as a component, an organic thin film in which a geometric two-dimensional arrangement is formed regularly by interdigitating skeletal structures of a positive three-pronged shape of triptycene and by adding a first molecule extending out of one plane of a two-dimensional molecular structure of the triptycene skeletal structure. The invention also relates to an electronic apparatus and the like which contains the electronic device in the interior of the electronic apparatus.

  • Patent number: 5963546
    Abstract: A method of searching for an available path in a mesh architecture in a multinode transmission system having a plurality of node apparatuses is disclosed. In setting a shortest path between first and second node apparatuses, the identity of a destination node and the immediate adjacent path along the shortest path from a source node are registered as path management data, for the source node, in a path management table. The identity of a destination node and the immediate adjacent path along the shortest path from each relay node is registered as path management data, for each relay node, in a path management table. Searching for an available path between two node apparatuses is performed on the basis of the path management data in the path management table. By limiting each data registration for each respective node to a destination and immediate path, the memory space for maintaining path management and control and the time required to search for an available path are reduced.
