  • Publication number: 20110293854
    Abstract: An atomic layer growing apparatus introduces an organic metal gas containing hydrogen to a deposition vessel to cause an organic metal component to be adsorbed on a substrate. Then, the apparatus introduces an oxidizing gas or a nitriding gas to the deposition vessel to generate plasma, thereby oxidizing or nitriding the organic metal component deposited on the substrate. When the plasma is generated, the apparatus detects emission intensity of a predetermined wavelength of light emitted on the substrate through an observation window provided in the deposition vessel. When the detected emission intensity becomes a predetermined value or less, the apparatus stops the generation of the plasma.

  • Publication number: 20110284770
    Abstract: A fluorescence detecting device generates a modulation signal for modulating an intensity of laser light and modulates the laser light by using the modulation signal, when receiving fluorescence emitted by a measurement object irradiated with laser light emitted from a laser light source unit. The fluorescence detecting device obtains a fluorescent signal of the fluorescence emitted by the measurement object irradiated with the laser light and calculates, from the fluorescent signal, the phase delay of the fluorescence with respect to the modulation signal. At the time, the fluorescence detecting device controls the frequency of the modulation signal so that the value of the phase delay comes close to a preset value. The fluorescence detecting device calculates the fluorescence relaxation time of the fluorescence emitted by the measurement object by using a phase delay obtained under the condition of frequency of the modulation signal at the time when the control is settled.

  • Publication number: 20110278471
    Abstract: In order to remove autofluorescence emitted by a measurement object, fluorescence of the measurement object within a first wavelength band is first received. The first wavelength band is set so that the intensity of fluorescence emitted by the measurement object irradiated with intensity-modulated laser light is higher than that of autofluorescence emitted by the measurement object irradiated with the laser light. Then, the autofluorescence within a second wavelength band different from the first wavelength band is received. A generated fluorescent signal of the first fluorescence and a generated fluorescent signal of the autofluorescence are mixed with a modulation signal for modulating the laser light to produce first fluorescence data and autofluorescence data, respectively. The autofluorescence data is multiplied by a predetermined constant, and the thus obtained result is subtracted from the first fluorescence data to produce third fluorescence data.

  • Publication number: 20110266462
    Abstract: When a fluorescence relaxation time of a fluorochrome is determined using a measurement object obtained by attaching the fluorochrome to an analyte, a first laser beam is intensity-modulated by a modulation signal with a frequency of f1 and a second laser beam is intensity-modulated by a modulation signal with a frequency of f2. A first fluorescent signal and a second fluorescent signal are obtained. The first fluorescent signal is mixed with the modulation signal with a frequency of f1 to produce first fluorescence data P1, and the second fluorescent signal is mixed with the modulation signal with a frequency of f2 to produce second fluorescence data P2. The fluorescence relaxation time is calculated using fluorescence data obtained by subtracting the result of multiplication of the second fluorescence data P2 by a second constant from the result of multiplication of the first fluorescence data P1 by a first constant.

  • Patent number: 8049185
    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.
