  • Patent number: 11906991
    Abstract: An electronic device includes first and second connecting wires to which first and second signal wires are connectable, respectively, and a first resistor. The first signal wire transmits a first signal between the electronic device and an external device. The second signal wire transmits a second signal from the external device to the electronic device. The first resistor is disposed between the first connecting wire and a power source of the electronic device. A resistance value of the first resistor is set such that an output voltage from the second connecting wire is lower than a reference value when a voltage of the power source is input to the second connecting wire via the first connecting wire and the external device in a state in which the first and second signal wires are electrically connected to one another and the second signal is not input to the second signal wire.

  • Publication number: 20230387434
    Abstract: If a difference between pressure values detected by a plurality of pressure detectors is equal to or greater than a predetermined value, a anode pressure in the fuel gas supply pipe is estimated based on a supply situation of the fuel gas supplied from a pressure regulator and a consumption situation of the fuel gas in a fuel cell stack, and it is determined that a pressure detector detecting a pressure value closer to an estimated pressure value is a normal pressure detector. Thereafter, a power generation operation of a fuel cell system is continued based on the pressure value of the pressure detector determined to be normal.

    Abstract: A fuel cell system includes a gas-liquid separator, a circulation flow path, a connecting flow path, and a distribution flow path. The gas-liquid separator separates fuel exhaust gas, which flows therein via a fuel exhaust gas flow path, into gas and liquid. The circulation flow path causes a gas discharge port of the gas-liquid separator and the fuel gas supply flow path to communicate with each other. The connecting flow path causes a liquid discharge port of the gas-liquid separator to communicate with the oxygen-containing gas supply flow path, via a drain valve. The distribution flow path causes the circulation flow path or a portion of the fuel gas supply flow path that is on a downstream side of a connecting section connecting to the circulation flow path to communicate with a downstream side of the drain valve of the connecting flow path via an opening and closing valve.

  • Patent number: 11097339
    Abstract: A casting plant to produce a cast product with a high quality and a method for managing data for molding the mold and data on the conditions of the molten metal in the casting plant are provided. The controller (11) for the molding unit issues a serial number for the mold to a mold (M). The controller (31) for the unit for conveying the molds shifts the serial number for the mold in accordance with a movement of the mold. It also gathers data on the mold and links the data for molding the mold with the serial number for the mold. When the molten metal is poured from the ladle into the mold, the controller (71) for the unit for pouring the molten metal sends to the computer (91) for controlling the casting plant the serial number for the ladle that is linked with the data on the conditions of the molten metal and that is linked with the serial number for the mold.
