  • Patent number: 8921626
    Abstract: The operation of a plant for producing a gas hydrate is stabilized by making the gas phase within a downstream step have the same equilibrium composition as that of the gas phase within a generation step. The gas phase within a mixed-gas hydrate generation step is circulated to the gas phase within a downstream step located downstream of the mixed-gas hydrate generation step, and the gas phase within each step is thereby made to have the same equilibrium composition as that of the gas phase within the generation step.

  • Patent number: 8885165
    Abstract: A fluorescence detecting device receives fluorescence emitted by n kinds of measurement objects within wavelength bands FLk (k is an integer of 1 to n) set so that the fluorescence intensity of fluorescence emitted by a measurement object k becomes higher than that of fluorescence emitted by the other one or more measurement objects, and acquires fluorescent signals corresponding to the wavelength bands FLk (k is an integer of 1 to n). Each of the fluorescent signals is subjected to frequency-down conversion by mixing it with a modulation signal for modulating the intensity of a laser beam Lk (k=1) corresponding to at least one of the wavelength bands FLk to produce fluorescence data including the phase delay and intensity amplitude of the fluorescent signal. The fluorescence data is corrected to calculate the phase delay and a fluorescence relaxation time is calculated using the phase delay.

  • Publication number: 20140203471
    Abstract: A method is for molding a gas hydrate pellet for improving convenience of handling of a natural gas hydrate during transportation and storage, and thereby improving the practical use of the natural gas hydrate. Gas hydrate slurry is fed in a compression chamber, and pressure and compression are applied to the gas hydrate slurry by advancing a compression plunger. At that time, a stroking speed of the compression plunger is set minimum, preferably less than a value expressed by a stroke length of the compression plunger at compression×10?2 (m/min). By advancing the compression plunger at low speed, binding between particles of the gas hydrate is tightened, thereby the gas hydrate pellet with increased shearing strength can be molded.

  • Patent number: 8772739
    Abstract: A fluorescence detection device generates a modulation signal for modulating the intensity of the laser light and modulates the laser light using the modulation signal. The detection device obtains a fluorescent signal of the fluorescence emitted by the measurement object irradiated with the laser light, and calculates, from the fluorescent signal, a fluorescence intensity and the phase delay of the fluorescence with respect to the modulation signal. At the time, the detection device controls the operation amounts of the signal level of a DC component of the modulation signal and the gain of amplification just after the output of the fluorescent signal so that the value of a fluorescence intensity signal falls within a preset range. After the operation amounts are settled, the detection device calculates the fluorescence intensity and then calculates the fluorescence relaxation time of the fluorescence emitted by the measurement object using the phase delay.

  • Patent number: 8642976
    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.
