Patent number: 9182422Abstract: When a flow of a liquid body around a measuring object is visualized, a first liquid body as a tracer is supplied from a nozzle hole into a flow field of a second liquid body, and a laser beam having a wavelength optically absorbed by the first liquid body is irradiated in a manner such that the laser beam traverse across the flow field. At this point, the irradiation position of the laser beam is controlled in such a manner that the flow field is scanned with the laser beam. On the other hand, the laser beam that has passed through the flow field is received and a position where the first liquid body traverses the laser beam is obtained using the scan intensity signal of the received laser beam so that the flow of the second liquid body is visualized. The position where the first liquid body traverses the laser beam can be obtained based on a position on a time axis where a value of the scan intensity signal is less than a set threshold.Type: GrantFiled: November 4, 2011Date of Patent: November 10, 2015Assignee: MITSUI ENGINEERING & SHIPBUILDINGInventors: Kazuteru Hoshishima, Noriaki Kimura

Publication number: 20100193703Abstract: 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.Type: ApplicationFiled: August 30, 2007Publication date: August 5, 2010Applicant: Mitsui Engineering & Shipbuilding Co., Ltd.Inventors: Noriaki Kimura, Shigeyuki Nakada, Kyouji Doi
