摘要:
For implementing a stop control which extracts a current from a fuel cell and consumes a cathode side oxygen at a system stop, the current extraction from the fuel cell is ended in a state that a certain quantity of oxygen smaller than when the current extraction is started remains on a cathode side of the fuel cell. With this, the hydrogen movement to the cathode side after the system stop can be effectively suppressed and thereby a cathode internal hydrogen concentration at the system start can be kept low, thus making it possible to properly process the cathode side hydrogen at the system start.

The present invention provides an ultimate analyzer which displays an element distribution image of an object with high contrast and high accuracy. A scanning transmission electron microscope and a method of analyzing elements using the ultimate analyzer is also provided. The ultimate analyzer comprises a scattered electron beam detector for detecting an electron beam scattered by an object; an electron spectrometer for energy dispersing an electron beam transmitted through the object; an electron beam detector for detecting said dispersed electron beam; and a control unit for analyzing elements based on an output signal of the electron beam detected by the electron beam detector and an output signal of the electron beam detected by the scattered electron beam detector.

A vehicle speed control system includes a first electronic control unit for transmitting a difference between actual and target vehicle speeds and control constants that vary depending on the vehicle speed difference when it determines fulfillment of vehicle speed control conditions, and a second electronic control unit for performing the vehicle speed control based on the vehicle speed difference and control constants received through a communication line. Change of the control constants for adjustment of a vehicle speed control function of the system can be easily carried out by changing the control constants stored in the first electronic control unit.

A fuel reforming system, comprising a reformer (2, 3, 4) which produces reformate gas from rich raw fuel gas, and supplies the reformate gas to the fuel cell (28) during a reforming operation, a burner (1) which produces lean combustion gas, and supplies the lean combustion gas to the reformer (2, 3, 4) during a warmup operation of the reformer (2, 3, 4), and a nonflammable fluid supply apparatus which supplies a nonflammable fluid other than fuel and air to the reformer (2, 3, 4). During the warmup operation of the reformer (2, 3, 4), the lean combustion gas is supplied from the burner (1) to the reformer (2, 3, 4), and when warmup of the reformer (2, 3, 4) is complete, the nonflammable fluid is supplied from the nonflammable fluid supply apparatus to the reformer (2, 3, 4), and the reforming operation of the reformer (2, 3, 4) then starts.

摘要:
In a network management system in which a management application performs management operations on respective managed objects in a communication network, a template management portion stores a processing sequence described by the user into a database, and when a start request is given from a management application, a processing sequence execution portion issues a table generating request to an internal table generating portion. The internal table generating portion generates tables and then delivers an end report and the generated tables to the processing sequence execution portion, so that the processing sequence execution portion executes management operations for managed objects on the basis of the set of tables. The aforementioned processing is repeated whenever a start-up request arises from the management application. Thus, a user not only can describe behavior of management services without consciousness of a program language but also can execute management operations by describing the behavior.

In an electrochromic display device having a plural number of indication electrodes displaying an information by repetition of coloring mode and discoloring mode, both modes of the indication electrodes being caused by an electrochemical oxidation-reduction reaction at the indication electrodes, and having an auxiliary electrode and counter-electrode to the indication electrodes and to the auxiliary electrode, the improvement is that an auxiliary electrode is further provided so as to act as the same acting mode as that of at least one of the indication electrodes, thereby removing an irregularity of color density of displaying at the acting indication electrodes.
摘要:
A fuel cell system including a plurality of single-cell units, each of which include an electrolyte membrane disposed between an anode and a cathode and which generate electric power by a reaction of a fuel gas in the anode and an oxidizer gas in the cathode, and a fuel cell in-which the plurality of single-cell units are stacked. A plurality of voltage measurement devices measure the voltages of the single-cell units, respectively. A control unit determines the humidification state of the fuel cell based on the voltage of a second single-cell unit wherein when the voltage of the second single-cell is equal to or lower than an insufficient-humidification-determining voltage which is higher than the predetermined voltage the control unit determines that humidification of the fuel cell is insufficient, disposed in the vicinity of a first single-cell unit, the first single-cell unit having a voltage that is equal to or lower than a predetermined voltage.
