Patent number: 11649962Abstract: A burner characterized by being equipped with: a fuel supply nozzle to which a mixed flow of a solid fuel and a solid fuel transport gas is supplied; a flow passage that is arranged on the outside of the fuel supply nozzle and that supplies combustion air separated from the mixed flow; and ammonia supply nozzles which are capable of supplying ammonia on the downstream side of the outlet of the fuel supply nozzle toward a reduction region in which oxygen in the transport gas has been consumed due to ignition of the fuel and the progress of combustion, resulting in a low oxygen concentration. Thus, it is possible to provide a burner capable of burning a mixture of a solid fuel and ammonia, and a combustion device equipped with this burner.Type: GrantFiled: May 13, 2019Date of Patent: May 16, 2023Assignee: MITSUBISHI HEAVY INDUSTRIES, LTD.Inventors: Kenji Kiyama, Yasuhiro Yamauchi, Kenichi Ochi, Hitoshi Taniguchi, Kosuke Kitakaze

Patent number: 11346546Abstract: This solid fuel burner is provided with: a venturi tube in which a channel for mixed fluid in a fuel nozzle narrows toward the center in the channel cross section; a fuel concentrator that imparts, to the mixed fluid, a velocity component away from the center of the fuel nozzle; and a channel separation member that separates the channel of the fuel nozzle into an internal side and an external side; wherein the channel separation member is shaped in such a way that the cross sectional area of an external channel is larger at the downstream end than at the upstream end, and the upstream end of the fuel concentrator is located between the upstream end and the downstream end of an expanded portion of the venturi tube. This solid fuel burner prevents solid fuel particles, which is ground biomass fuel, from adhering and depositing inside the nozzle.Type: GrantFiled: April 16, 2018Date of Patent: May 31, 2022Assignee: MITSUBISHI POWER, LTD.Inventors: Kenichi Ochi, Hitoshi Taniguchi, Akira Baba, Koji Kuramashi, Kosuke Kitakaze, Shohei Mito, Hitoshi Kikuchi

Patent number: 10979014Abstract: To improve the performance of the voltage filter. Rather than reducing an area of a region surrounded by a closed loop formed in a voltage filter 12A, an induced electromotive force generated in the voltage filter 12A itself is reduced by forming a pair of a closed loop CA and a closed loop CB in which the directions of the generated induced electromotive forces are opposite to each other by making a wiring 100 (anode wiring) intersect a wiring 200 (cathode wiring).Type: GrantFiled: November 13, 2019Date of Patent: April 13, 2021Assignee: HITACHI, LTD.Inventors: Hitoshi Taniguchi, Hiroki Funato

Patent number: 8904233Abstract: A failure caused by a soft-error including MNU, of an electronic apparatus is prevented, while suppressing increase of a mounting area, power consumption, and processing time. The electronic apparatus stores data indicating the state of a flip-flop included in a sequential logic circuit within an arithmetic unit, each time when execution is performed on a check point provided for every predetermined number of instructions. When a symptom of a soft-error is detected, the apparatus sets the state of the flip-flop included in the sequential logic circuit within the arithmetic unit, based on the data stored after execution of the instruction at the immediately preceding check point, and restarts execution from the next instruction, being subsequent to the instruction associated with the immediately preceding check point.Type: GrantFiled: February 9, 2011Date of Patent: December 2, 2014Assignee: Hitachi, Ltd.Inventors: Hidefumi Ibe, Tadanobu Toba, Kenichi Shimbo, Hitoshi Taniguchi
