Cryogennic liquefied gas intake/discharge valve body, reciprocating pump, and fuel gas supply device
Patent number: 9719500Abstract: A fluid intake/discharge valve body for suction of a cryogenic liquefied gas fluid into a cylinder liner and discharge of the gas fluid with a piston, includes: a valve seat body including a fluid supply portion to supply the fluid and a fluid exhaust portion; an intake valve biased against the fluid supply portion; and a discharge valve biased against the fluid exhaust portion. The fluid supply portion includes a supply pathway connected to a supply pipe; a dividing wall including intake holes facing the intake valve; and a counterbore recessed portion on the dividing wall to surround the intake holes. The intake valve abuts an edge of the recessed portion when biased against the fluid supply portion. The discharge valve receives fluid pressure from a side of the discharge hole including a recessed portion disposed in a region wider than an outer periphery of the discharge hole.Type: GrantFiled: December 26, 2014Date of Patent: August 1, 2017Assignee: MITSUI ENGINEERING & SHIPBUILDINGInventors: Makoto Kounosu, Renzo Kanda -
Patent number: 9376754Abstract: A method includes introducing an organic metal gas containing hydrogen into a deposition vessel to cause a component of the organic metal containing hydrogen to be adsorbed on a substrate; introducing an oxidizing gas or a nitriding gas into the vessel, generating plasma with the oxidizing gas or the nitriding gas by a plasma source, and oxidizing or nitriding the component; detecting emission intensity of a wavelength of light through an observation window in the vessel, the light being emitted, by generating the plasma, from an excited hydrogen radical resulting from the hydrogen separated from the organic metal above the substrate when the organic metal reacts with the oxidizing gas or the nitriding gas to form an oxidized metal or a nitride metal on the substrate; and stopping the generation of the plasma when a value of the detected emission intensity becomes a first predetermined value or less.Type: GrantFiled: October 4, 2013Date of Patent: June 28, 2016Assignee: MITSUI ENGINEERING & SHIPBUILDINGInventor: Kazuki Tanizawa

Patent number: 9291563Abstract: FRET measurement uses a FRET probe that includes a probe element X containing a donor fluorescent substance and a probe element Y containing an acceptor fluorescent substance and enables FRET to occur when the probe element X and the probe element Y approach to each other or bind together. The modulation frequency of laser light with which the FRET probe is irradiated is adjusted to an optimum modulation frequency that maximizes a difference between the phase difference of donor fluorescence emitted from the donor fluorescent substance with respect to intensity modulation of the laser light at the time when FRET occurs and the phase difference of donor fluorescence emitted from the donor fluorescent substance with respect to intensity modulation of the laser light at the time when FRET does not occur.Type: GrantFiled: March 22, 2013Date of Patent: March 22, 2016Assignees: MITSUI ENGINEERING & SHIPBUILDING, NATIONAL UNIVERSITY CORPORATION HOKKAIDO UNIVERSITYInventors: Shigeyuki Nakada, Yusuke Ohba, Kyouji Doi, Yumi Asano

Patent number: 9194043Abstract: An atomic layer deposition apparatus for forming a thin film on a substrate, including a first container that defines a first inner space, a second container provided inside the first container to define a second inner space, the second container being canister-shaped and including a first opening at one end thereof, a source gas that forms the thin film on the substrate flowing to the second inner space through the first opening, and a pressing member including a gas supply port for supplying the source gas to the second inner space through the first opening, the pressing member being configured to press the second container in a longitudinal direction of the second container so that the second inner space be separated from the first inner space.Type: GrantFiled: February 15, 2010Date of Patent: November 24, 2015Assignee: MITSUI ENGINEERING & SHIPBUILDINGInventors: Hiroyuki Tachibana, Kazutoshi Murata, Naomasa Miyatake, Yasunari Mori

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

Patent number: 6949226Abstract: A sodium-based dechlorinating agent is added to a flue gas; hydrogen chloride contained in this flue gas is removed as residue of dechlorination; the thus removed residue of dechlorination is dissolved by adding water; water-insoluble constituents are separated from the resulting aqueous solution; and after adjusting pH of the aqueous solution remaining after separation of the water-insoluble constituents, mercury, dioxin, and the like are removed and discharged. The sodium-based dechlorinating agent is mixed with a hydrophilic anti-caking agent, with an angle of repose of 40° or more, a dispersibility of less than 50, and a floodability index value of less than 90. This permits inhibition of occurrence of a pressure drop and leakage in the filter cloth of the dust collector.Type: GrantFiled: June 25, 2001Date of Patent: September 27, 2005Assignees: Mitsui Engineering & Shipbuilding, Asahi Glass Company Ltd.Inventors: Tomio Sugimoto, Masumi Itaya, Yoshinao Hirano, Hiroaki Harada, Hachiro Hirano, Sigeru Sakurai, Makoto Yoshida, Masaharu Tanaka

Publication number: 20050199614Abstract: It is an object of the present invention to prevent temperature decrease in a border portion of each of heating coils and to enable to eliminate an influence given by the change in a load state. In order to attain this object, an induction heating unit 400 according to the present invention is provided with control units 420 (420a to 420d) respectively corresponding to a plurality of heating units 310 (310a to 310d). A phase detector 424d of the control unit 420d obtains a phase difference between an output current (heating coil current IL4) of an inverter 314d detected by a current transformer 160d and a reference signal outputted by a reference signal generating section 426, and inputs it to a drive control section 422d. The drive control section 422d adjusts an output timing (phase) of a gate pulse to be given to the inverter 314d so as to make a phase of the heating coil current IL4 of the inverter 314d coincide with a phase of the reference signal outputted by the reference signal generating section 426.Type: ApplicationFiled: June 26, 2002Publication date: September 15, 2005Applicant: MITSUI ENGINEERING & SHIPBUILDINGInventors: Naoki Uchida, Keiji Kawanaka, Hideyuki Nanba, Kazuhiro Ozaki
