    Abstract: An atomic layer growing apparatus includes a deposition container, a gas supply unit, and an exhaust unit. In the deposition container, an antenna array and a substrate stage are provided. The antenna array is formed by disposing a plurality of antenna elements in parallel, each of the antenna elements being configured by coating a rod-shaped antenna body with a dielectric material. The antenna array generates plasma using one of an oxidizing gas and a nitriding gas. The substrate is placed on the substrate stage. The gas supply unit alternately supplies the source gas and the oxidizing gas toward the substrate stage from a supply hole made in a sidewall of the deposition container when a film is formed on the substrate. The exhaust unit exhausts the source gas and one of the oxidizing gas and the nitriding gas, which are alternately supplied into the deposition container.

  • Publication number: 20100314557
    Abstract: In a fluorescence detection device and a fluorescence detection method, forward-scattered light which is scattered from a measurement object irradiated with a laser beam is received and detection signals for informing the measurement object passing through the measurement point and for identifying a focus position of the forward-scattered light are produced. While, fluorescence emitted by the measurement object is received through a collecting lens and a light-reception signal of the fluorescence is outputted. The fluorescence intensity level is outputted based on the outputted light-reception signal and the produced detection signals. A focus position of the forward-scattered light is identified from the produced detection signals and the light reception-signal is corrected using a correction coefficient corresponding to the identified focus position.

  • Publication number: 20100312482
    Abstract: When FRET efficiency is measured quantitatively by removing uncertain elements of fluorescence detection information, calibration information prestored in a storage means while including at least the leak rate of donor fluorescence component emitted from a donor molecule, the leak rate of acceptor fluorescence component emitted from an acceptor molecule, and the non-FRET fluorescence lifetime of the donor fluorescence component when FRET is not generated out of the fluorescence of a measurement object sample is acquired. The FRET fluorescence lifetime of the donor fluorescence component is then determined using the intensity information and phase information of fluorescence of the measurement object sample, the leak rate of donor fluorescence component and the leak rate of acceptor fluorescence component, thus determining the FRET fluorescence efficiency.

  • 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.

  • Publication number: 20100193703
    Abstract: When FRET (Fluorescence Resonance Energy Transfer) detection of a large number of samples is performed in a short time for a sample consisting of a donor molecule and an acceptor molecule, the donor molecule is irradiated at first with first laser light used for exciting a donor molecule subjected to intensity modulation at a frequency of f+?f, the accepter molecule is irradiated with second laser light used for exciting an acceptor molecule subjected to intensity modulation at a frequency of f, and fluorescence emitted from the accepter molecule is received. From a fluorescence signal thus received, a first signal component of fluorescence emitted from the accepter molecule through FRET, and a second signal component of fluorescence emitted from an accepter molecule excited through irradiation with the second laser light are extracted. Phase lags of the first and second signal components thus extracted are then calculated and the presence of generation of FRET is judged based on these phase lags.

  • Publication number: 20100131226
    Abstract: A laser beam with a wavelength capable of exciting atoms of helium in the metastable state is directed to a generated plasma, and atoms in the metastable state are excited. Absorption amount information representing the amount of laser beam absorbed is acquired, and the density of atoms of helium in the metastable state in the plasma is computed from the absorption amount. The emissions of light from helium gas in the plasma caused by transition from two different excited states to the lower level are measured, and the ratio between the intensities of the emissions is determined. The electron temperature of the produced plasma is computed from the computed density of the atoms of helium gas in the metastable state and the computed emission intensity ratio. With this, the plasma electron temperature can be computed with a relatively high accuracy irrespective of the condition of the plasma atmosphere.
