摘要： The injector (1) has a pipe unit (3), and a valve unit (6) sliding axially in the pipe unit. The valve unit comprises a central region, and plate regions that protrude radially from the central region. A guiding region is provided with an outer region that defines a valve seat. The guiding region is arranged for redirecting flow of fuel that is supplied along the plate regions to an injection opening in a radial inner direction.

摘要： According to the present invention, when electronic money is sent from a given network to another network, a money change apparatus performs a money change process to change electronic money current on the given network into electronic money current on another network, and therefore when a user of the given network uses a settling process, by managing this money change process, it is possible to manage the interchange of electronic money between each of the users of the given network and each of the users of another network without affecting the working environment of electronic commerce. Electronic money current on LAN20 is referred to as local electronic money current only on the network. When a terminal NLU4 connected to LAN20 sends money to a terminal NWU2 connected to WAN10, GW1 for controlling the flow of data between LAN20 and WAN10 receives local electronic money sent from the terminal NLU4, changes the local electronic money into electronic money current on WAN10, then sends the electronic money to the terminal NWU2, and when a terminal NWU2 sends money to a terminal NLU4, GW1 receives electronic money sent from the terminal NWU2, changes the electronic money into local electronic money and sends the local electronic money to the terminal NLU4.

摘要： In a gas turbine apparatus (113) including a turbine stage (123) and a compressor stage (125), when an abrupt load variation occurs in a centrifugal compressor (101) which increases pressures of a fuel such as city gas or liquefied natural gas to feed the fuel, a gas turbine control device (1) effects a control so that a discharge pressure of the centrifugal compressor can be kept to within a predetermined pressure range. When a fuel flow demand for the centrifugal compressor is inputted to the gas turbine control device, a signal corresponding to this fuel control signal is inputted to a bypass valve (107) of the centrifugal compressor simultaneously when it is inputted to gas turbine fuel control valves (42, 48) provided in the gas turbine apparatus. When the load is abruptly varied, the degree of opening of the bypass valve of the centrifugal compressor is changed to a value determined by a prestored relation between the fuel control signal and the degree of opening of the bypass valve.

摘要： A master controller (MC) receives a load demand and a plurality of plant data from a heat power plant and outputs command signals on at least two of an electric power, a feed water flow rate, a fuel flow rate, an air flow rate and a recirculation gas flow rate of the plant required to achieve the load demand. A plurality of sub-loop controllers (SLC) independently provided one for each of the command signals provide control quantities for controlling respective control ends in accordance with the command signals. A transmission loop is arranged between the sub-loop control- lera and the master controller. Drive means (40) drive the control terminals provided one for each of the control quantities supplied from the sub-loop controllers. An I/O bus (80) is arranged between one of the sub-loop controllers and the drive means driven by the command signal for the one sub-loop controller. Detection means detect the plant data to be delivered to the master controller or the sub-loop controllers.
