  • Publication number: 20050170230
    Abstract: A liquid fuel cell system is disclosed. The liquid fuel cell system includes a liquid fuel cell unit and a liquid fuel cartridge that can be connected to the liquid fuel cell unit. The liquid fuel cell unit and the liquid fuel cartridge each include a valve unit. The liquid fuel cartridge is connected to the liquid fuel cell unit so as to pour and supply liquid fuel that is a methanol solution from the liquid fuel cartridge to the liquid fuel cell unit. Using the supplied liquid fuel, the liquid fuel cell unit generates power to charge a battery. After the charging, both of the valve units are opened to return the liquid fuel remaining in the liquid fuel cell unit back to the liquid fuel cartridge, and thus, the liquid fuel cell unit is emptied.

  • Patent number: 6798077
    Abstract: A semiconductor device having electrodes formed along a peripheral part thereof in a staggered arrangement of lines including inside-line, central-line and outside-line electrodes. The inside-line electrodes are octagonal shaped with hypotenuses on the central-line electrode and the pellet sides thereof. The central-line electrodes are octagonal shaped with hypotenuses on the inside-line and outside-line electrode sides thereof. The maximum width of outside-line electrode wires between the hypotenuses of adjacent inside-line and central-line electrodes depends on the distance between centers of the inside-line and central-line electrodes, minimum lengths of the inside-line and central-line electrodes and electrode protective film, and the necessary minimum conductor interval between the central-line and inside-line electrodes. The position and form of the central-line and inside-line electrodes are determinable based on the given relationship and the necessary value of current.
