  • Publication number: 20110168917
    Abstract: A fluorescence detection device for a flow site meter emits laser light intensity-modulated in accordance with a modulation signal and acquires a fluorescent signal of fluorescence emitted from a measurement object that passes through a measurement point of the laser light. The fluorescence detection device generates, separately from the modulation signal, a reference signal having a frequency different from a frequency of the modulation signal and a phase in synchronization with a phase of the modulation signal. The fluorescence detection device determines a fluorescent relaxation time of the measurement object from the fluorescent signal by using the reference signal.

    Abstract: A water treatment system to be installed in a tanker or other cargo ship for destruction of aquatic organisms and microorganisms that may be contained in the water, usually seawater, being pumped into the ship's ballast tank or tanks. Included is a ballast pump having an intake conduit for drawing water from the sea, and a delivery conduit for delivering the water under pressure to the ballast tank. The delivery conduit has mounted therein a slitted or otherwise open-worked screen for mechanically killing the aquatic lifeforms contained in the water by shearing action. For chemical treatment, on the other hand, part of the water being delivered by the ballast pump is bypassed into an ozone impregnator thereby to be impregnated with ozone from an ozonizer. A bypass pump repressurizes the ozone-impregnated water for returning the same into the delivery conduit.

  • Patent number: 7815888
    Abstract: Disclosed is a process for producing a secondary battery cathode material by calcining raw materials. The process is characterized by calcining the raw materials together with one or more substances, which are selected from the group consisting of hydrogen, water and water vapor, and conductive carbon and/or a substance, which can form conductive carbon by pyrolysis, added thereto. As crystals of the secondary battery cathode material obtained by this process have been controlled fine sizes, the secondary battery cathode material promotes movements of ions of an alkali metal led by lithium between the interiors of grains of the cathode material and an electrolyte to suppress polarization in an electrode reaction, and further, increases an area of contact between the positive material and a conductivity-imparting material to provide improved conductivity so that improvements are assured in voltage efficiency and specific battery capacity.
