    摘要: Conventional network quality monitoring systems require high monitoring cost, because: physical maintenance cost is high, since monitors are required to install on many portion of the network; the number of monitoring flows is apt to increase; the cost for information synchronization between monitors is required; and the network cost to collect information from apparatuses is required. In the present invention, based on a network whose route is definable by an external controller and changing the monitoring flow route appropriately, it is possible to perform monitoring of the communication quality under a small number of monitoring terminals and flows. Further, the role of the monitoring flow is divided into the monitoring flows to monitor the quality degradation occurrence and to specify the quality degradation point. The former is used for normal time, and the latter is for the quality degradation time. Consequently, the network monitoring system reducing the cost is proposed.

    摘要: Microorganisms (dielectric microparticles) in a liquid sample are captured using a dielectrophoretic force. After quantifying and analyzing, the microorganisms thus captured are concentrated and collected. In an apparatus for concentrating dielectric microparticles, a liquid sample, which contains the microorganisms to be examined, is supplied from a liquid sample-holding unit holding the liquid sample and passes through a voltage-applied cell. During the passage, the microorganisms are captured on dielectrophoretic electrodes by a dielectrophoretic force. Then, the captured microorganisms are released from the dielectrophoretic force by ceasing the voltage application. At the same time, a release liquid supplied from a release liquid-holding unit is flown through the dielectrophoretic electrodes so that the concentrated microorganisms are released and collected into a collection unit as the target bacteria.

    摘要: A semiconductor laser device has a semiconductor laser element placed inside a package on an electrically conductive submount such that one of the electrodes with one conduction type sandwiching its p-n junction is electrically connected to it. The submount is placed on a metallic heat sink, separated therefrom by a layer of an electrical insulator having a larger thermal conductivity than the submount. The other electrode of the laser element (of the opposite conduction type) is electrically connected to the heat sink, and one of externally extending lead pins is electrically connected to the submount. According to a preferred embodiment, the other electrode of the laser element is electrically connected instead to one of the lead pins and the submount is electrically connected instead to another of the lead pins. Thus, the capacitance of the submount and the inductance of the package will be in an electrically floating condition when the laser device is activated, and the device is adapted for high-frequency operations.

    摘要: In a coal gasification power generator, coal gas 500 obtained by gasifying a coal 100 by a gasifying furnace is introduced into a desulfurization furnace in which the coal gas 500 is desulfurized by limestone 400. A coal gas 501 after desulfurization is burned by a combuster 5 after it has passed through a dust removing unit 3 so that high temperature combustion gas 800 is supplied to a gas turbine. The gas turbine 7 drives a power generating unit. Exhaust gas 801 from the gas turbine is supplied to an exhaust gas boiler 8. Char 60a produced in the gasifying furnace and limestone 60b containing CaS emitted from the desulfurization furnace are burned in an oxidation furnace, and by using the resultant combustion gas, water vapor introduced from the exhaust gas boiler 8 is heated by a heat exchanger, and thereafter it is supplied to the gasifying furnace as a gas. With the above construction, chemical energy possessed by the coal is effectively converted into electric energy, and also the rate of desulfurization of coal gasifying gas is improved thereby reducing emitted sulfur oxide.

    摘要: A semiconductor laser includes an active layer having a light-emitting region of striped structure. A cladding layer is formed on the active layer. Another cladding layer is formed under the active layer. The active layer is interposed between the cladding layer and the another cladding layer. Facets are formed on both ends of a stripe of the light-emitting region in which a part of light emitted radiated, and the remaining light is reflected and amplified. The semiconductor laser includes a means for having a minimum value of a coherence in a range between 2 mW and 7 mW of output of a light radiated from one of the facets which is a light output, and for preventing a phenomenon in which the output is reduced in a range at most 25 mW in accordance with an increase of the current, varied by a variation of a current applied to the active layer.
