Abstract: A hub for a human-powered vehicle is provided that comprises a hub axle, a hub body, an electric power generator, and a communication device. The hub body is rotatably mounted on the hub axle about a rotational axis. The electric power generator is provided between the hub axle and the hub body. The electric power generator is configured to generate electric power by relative rotation between hub axle and the hub body. The communication device is located at least partly outside of the hub body. The communication device includes a wireless communicator configured to wirelessly communicate with an additional wireless communicator.

Abstract: The server device includes a communication unit and a control unit that performs communication using the communication unit, and the control unit determines the remaining battery level based on information about the user's travel schedule and the remaining battery capacity of the user's vehicle. A point and time at which a predetermined state will occur is predicted, and information proposing dispatch of a power supply vehicle to the point is sent to the user's terminal device at the time, prompting the user to decide on the dispatch.

Abstract: The server device includes a communication unit and a control unit that performs communication using the communication unit. The control unit sends a movement instruction to the first power supply vehicle to the position of the power supply vehicle when the traffic situation around the power supply vehicle that requires power supply is a first situation. When the traffic situation is a second situation where the degree of congestion is higher than the first situation, the control unit causes a second power supply vehicle having a higher power generation capacity than the first power supply vehicle to move to the position of the power supplied vehicle. Send movement instructions.

Abstract: A server device includes a communication unit and a control unit. The control unit is configured to acquire information on a first power purchase price from a charging point and a second power purchase price from a facility, and when the second power purchase price is lower than the first power purchase price, send to a power supply vehicle configured to supply power to another vehicle an instruction to move along a travel route that passes through the facility.

Abstract: The server device communicates with a plurality of power supply vehicles that dispatch from a power supply base to the power supply destination and return to the power supply base through the communication unit through the communication unit, and performs a first power supply during returning. a control unit that instructs the vehicle and a second power supply vehicle on the move to merge at a junction and provide the remaining power of the first power supply vehicle to the second power supply vehicle.

Abstract: A server apparatus includes a communication interface, and a controller configured to communicate with vehicles using the communication interface, acquire information on a required charge amount and a position of a vehicle that needs to be charged, and provide instructions that a power supply vehicle that does not have the required charge amount is to travel a route where road surface power supply is available to the position.

Abstract: A fuel supply system includes: a fuel gas supply line configured to supply a fuel gas to a combustor of a gas turbine; a first off-gas supply device configured to supply a first off-gas generated in a fuel refining plant to the combustor; a second off-gas supply device configured to supply a second off-gas generated in a bio-liquid fuel production plant to the combustor, the second off-gas having a calorific value per unit mass smaller than the fuel gas; a gas mixing device configured to mix the fuel gas supplied by the fuel gas supply line, the first off-gas supplied by the first off-gas supply device, and the second off-gas supplied by the second off-gas supply device; and a mixed gas fuel supply line configured to supply a mixed gas fuel produced by the gas mixing device to the combustor.

Abstract: A gas turbine cogeneration system includes: a gas turbine; a first fuel supply facility for supplying a first fuel to the combustor; a second fuel supply facility for supplying a second fuel with a calorific value per mass lower than the first fuel; a heat recovery steam generator for generating steam using exhaust gas discharged from the turbine; a steam supply line for supplying steam discharged from the heat recovery steam generator to a steam consumer; a steam extraction line for supplying steam extracted from the steam supply line to both a head end side of the combustor and a turbine side of the combustor; and a fuel control part for controlling the first and second fuel supply facilities so that the amount of the first fuel decreases and the amount of the second fuel increases with a decrease in extraction amount of steam by the steam extraction line.

Abstract: A gas turbine cogeneration system includes a denitration control part for outputting to a denitration device a control command to set the amount of NOx emissions at a heat recovery steam generator outlet not more than a boiler outlet target value. The denitration control part is configured to generate the control command with reference to at least a first addition amount of a reducing agent obtained by calculation based on a NOx parameter which is a parameter correlated with the amount of NOx emissions at a turbine outlet.

Abstract: Casing 5 is formed with a recess 67 toward an internal space in which the internal components are not located. The recess 67 is formed with a gate portion 69 as a resin inlet for forming the casing 5, and a bleeder portion 68 which is opened during a sealing operation and then sealed.

Abstract: In an electromagnetic relay in which a contact mechanism 50 provided on a base 10 is driven by a card 60 which slides and moves in parallel to the axis of an electromagnet block 20 provided in the base 10 as the electromagnet block 20 is magnetized and demagnetized, the base 10 comprises a guide portion 17 for restricting the card 60 in its position. This prevents variations in the performance characteristics so that high productivity and long service life of contacts can be obtained.

Abstract: In order to recover the heat of the waste gas from a gas turbine, a waste heat recovery boiler is provided, which has a high-pressure steam generating portion consisting of an economizer, a high-pressure steam generator and a superheater, and a low-pressure steam generating portion consisting of an economizer, and a low-pressure steam generator. The steam from the high-pressure generating portion is supplied to the turbine through a high-pressure steam pipe, and the steam from the low-pressure steam generating portion to the same through a low-pressure steam pipe. The high-pressure gland sealing steam is supplied to a high-pressure side steam gland portion the steam turbine through a high-pressure steam extracton pipe branching from the high-pressure steam pipe, a steam pressure regulator adapted to regulate the steam pressure and introduce the excess steam to a condenser, and a high-pressure gland sealing steam pipe.
