  • Patent number: 6969503
    Abstract: A carbon fiber has a coaxial stacking morphology of truncated conical tubular graphene layers, wherein each of the graphene layers includes a hexagonal carbon layer and has a large ring end at one end and a small ring end at the other end in the axial direction. When the carbon fiber is subjected to a heat treatment in a non-oxidizing atmosphere, the large ring ends of each two of the hexagonal carbon layers are linked by layer link sections in at least one of groups of the hexagonal carbon layers arranged in an axial direction, and an outer surface is closed to have a multi-semiring structure in cross section. When the carbon fiber is then subjected to a heat treatment in an oxidizing atmosphere, the layer link sections are released, whereby the edges of the hexagonal carbon layers are exposed at the large ring ends in a regularly arranged manner.

  • Patent number: 6915346
    Abstract: A connection unit for a computer, which is connectable to a network, is configured such that in response to a receipt by the connection unit of a predetermined wake-up packet via the network, a predetermined signal is generated. Following which, in response to the predetermined signal, the receipt of the predetermined wake-up packet is persistently displayed utilizing a dedicated display. With these means, a user of the computer is enabled to recognize the fact execution of WOL has been carried out or attempted, without running a specific application (adapted for informing the user of the fact that WOL was executed) on the computer, or even where the computer is not connected to the connection unit.
