Abstract: Provided is a method that enables the presence and/or amount of bacteria of Enterobacteriaceae in a food/drink sample, an environmental sample, or a biological sample to be detected easily and efficiently in a short amount of time. Said method includes a step for simultaneously detecting, on the basis of an antigen-antibody reaction, the presence and/or amount of bacteria of Enterobacteriaceae of at least two different genera in a sample.

Abstract: Provided is a method that makes it possible to detect the presence and/or amount of bacteria in a food/drink sample, environmental sample, or biological sample in a short period of time, simply, and efficiently. This method comprises a step in which the presences and/or amounts of bacteria of two or more different genera in a sample are simultaneously detected on the basis of antigen-antibody reactions.

Abstract: A scour prevention unit includes a bag body housing block objects in a bag material, and a cloth integrated with the bag body, wherein the cloth is housed in the bag material and is laid below the block objects, or is fixed below the bag body outside the bag body by fixing means.

Abstract: Detection rapidly and with high detection intensity is accomplished while blackening is inhibited during silver enhancement to detect an analyte in a specimen.

Abstract: A power conversion system includes a transformer, a power conversion device for travel, a power conversion device for auxiliary power sources, an electrical storage device, and an auxiliary device. The power conversion device for travel converts AC power into power for travel and supplies it to a travel motor. The power conversion device for auxiliary power sources includes an AC to DC conversion unit which converts AC power into DC power, a power conversion unit for AC loads which converts the DC power into AC power and supplies it to an AC load, and a power conversion unit for DC loads which converts DC power to DC power and supplies it to a DC load. The electrical storage device is connected to power lines connecting DC power output terminals of the AC to DC conversion unit and DC power input terminals of both the power conversion units for AC and DC loads.

Abstract: A power conversion system includes an AC to DC conversion circuit, a voltage detector, a step-down chopper circuit, a power conversion device for auxiliary power sources, and a control unit. The AC to DC conversion circuit converts AC power supplied from overhead wires via a transformer into DC power. The voltage detector detects a voltage of AC power supplied from the transformer. The step-down chopper circuit steps down the voltage of DC power produced through conversion by the AC to DC conversion circuit. The power conversion device for auxiliary power sources converts the DC power stepped down by the step-down chopper circuit into power for driving loads mounted in an electric vehicle and supplies it to the loads. The control unit controls the AC to DC conversion circuit and the step-down chopper circuit such that the voltage of AC power detected by the voltage detector approaches a reference voltage.

Abstract: A power conversion system includes a transformer, a power conversion device for travel, a power conversion device for auxiliary power sources, and an electrical storage device. The power conversion device for auxiliary power sources includes a first AC to DC conversion unit, a power conversion unit for AC loads, and a power conversion unit for DC loads. The power conversion unit for AC loads converts DC power into AC power and supplies it to an AC load. The power conversion unit for DC loads converts DC power produced through conversion by the first AC to DC conversion unit into DC power and supplies it to a DC load. The electrical storage device is connected to power lines connecting DC power output terminals of the first AC to DC conversion unit and DC power input terminals of both the power conversion units for AC and DC loads.
