  • Patent number: 10844792
    Abstract: To provide a damping device that includes an acoustic liner that forms an acoustic-liner resonant space along an outer periphery of a combustion chamber in which a combustion gas flows, and an acoustic damper provided on an outer peripheral side of the acoustic liner, to form an acoustic-damper resonant space that communicates with the acoustic-liner resonant space. The acoustic liner is formed with a damper opening connected with the acoustic damper for causing the acoustic-liner resonant space and the acoustic-damper resonant space to communicate with each other. The acoustic liner includes a divided portion that is a portion to be divided in a circumferential direction of the combustion chamber by the damper opening, and a continuous portion that is a portion continuous over the circumferential direction of the combustion chamber.

  • Publication number: 20200291872
    Abstract: A fuel control device includes a stem fuel valve opening degree determination unit, a branch line flow rate determination unit, and a correction value determination unit. The stem fuel valve opening degree determination unit is configured to determine an opening degree of a flow rate adjustment valve of a stem fuel supply line. The branch line flow rate determination unit is configured to determine the opening degree of each flow rate adjustment valve of the branch line based on an operation situation of the gas turbine. The correction value determination unit is configured to determine a correction value of the opening degree of each flow rate adjustment valve of the branch line based on a value of a pressure difference between a fuel pressure upstream of each of nozzles connected to the branch lines respectively and a corrected fuel pressure for the fuel pressure at an outlet.

  • Patent number: 10603936
    Abstract: A printer includes a carriage, a carriage moving mechanism including a motor, a motor driver that controls the motor, a stop instruction device, and an interlock device. The stop instruction device transmits a stop signal for the carriage or stops a driving permission signal for the carriage when a predetermined stop condition is satisfied. The interlock device is interposed between the motor and the motor driver and shuts off the motor from the motor driver after a lapse of a predetermined delay time of transmitting the stop signal or stopping the driving permission signal. The motor driver controls the motor to decelerate the carriage in at least a portion of a period before the delay time has elapsed.

  • Patent number: 10535435
    Abstract: It is possible to achieve self-support of the fuel assembly without an upper grid plate when the fuel assembly is mounted or replaced, and it is also possible to prevent the fuel assembly from floating during a reactor operation. According to the present invention, the lower portion of the lower tie plate 7 as a part of the fuel assembly 3, which is inserted into the fuel support 9, extends, and a stable member 21 is provided around the extension portion 20, and thereby it is possible to achieve the self-support of the fuel assembly without the upper grid plate. In addition, since an increase in a weight due to extension of the lower portion of the lower tie plate 7 can prevent the floating during the reactor operation, a floating preventing mechanism using the upper grid plate is not necessary.

  • Publication number: 20190368730
    Abstract: A resonant sound absorbing device of a gas turbine combustor includes a plurality of resonance chambers independently disposed side by side in an axial direction of the gas turbine combustor so as to communicate with a gas passage of the gas turbine combustor via acoustic holes. The plurality of resonance chambers include n related resonance chambers each satisfying: 0.9 × ? i = 1 n ? F i n ? F i ? 1.1 × ? i = 1 n ? F i n ( A ) where n is an integer of 2 or more, and Fi is a peak frequency corresponding to a maximum sound absorbing ratio of the ith related resonance chamber of the n related resonance chambers.

  • Patent number: 10486443
    Abstract: A controller includes a cutter movement controller that controls a value of an electric current to flow in a voice coil motor to apply a first electromagnetic force to a holder in a downward direction for a first time duration, then to apply the first electromagnetic force to the holder in an upward direction for a second time duration shorter than the first time duration, to pause the supply of the electric current to the voice coil motor for a third time duration longer than the second time duration, then to apply a third electromagnetic force, which is smaller than, or equal to, the first electromagnetic force and is an electromagnetic force applied to cut a cutting target, to the holder in the downward direction for a fourth time duration longer than the first time duration, and thus to cause a cutter to contact the cutting target, and a cutting controller that, after a predetermined time duration from the time when the electric current starts to flow in the voice coil motor, controls a carriage and a con
