  • Patent number: 11311833
    Abstract: A method for recovering an acidic gas, includes: a step of bringing a gas to be treated that contains an acidic gas into gas-liquid into contact with an amine absorbing solution, allowing the amine absorbing solution to absorb the acidic gas, thereby removing the acidic gas from the gas to be treated; a step of allowing the amine absorbing solution that has absorbed the acidic gas to release the acidic gas, thereby regenerating the amine absorbing solution, and at the same time, recovering the released acidic gas; and an analysis step of calculating concentrations of iron ions and/or heavy metal ions in the amine absorbing solution.

  • Patent number: 11290051
    Abstract: A motor control apparatus includes a motor, a motor driver to drive the motor, a motor current detection unit, a motor state estimation unit, a motor control unit, and first and second abnormality detection units. The motor current detection unit detects a current value of the motor. The motor state estimation unit estimates a state of the motor based on a voltage applied to the motor and the detected current value. The motor control unit applies a driving voltage of first driving corresponding to the estimated state of the motor or apply a driving voltage of second driving, which does not use the estimated motor state, to the motor driver. The first abnormality detection unit detects a rotation abnormality of the motor based on the estimated motor state. The second abnormality detection unit detects the rotation abnormality of the motor based on the detected current value of the motor.

  • Publication number: 20210374309
    Abstract: A model generating part generates an analysis model for an airflow analysis of an indoor space. A temperature distribution estimating part performs the airflow analysis of the indoor space by using the analysis model and estimates a temperature distribution in the indoor space. A communication part acquires a temperature measured at a measurement point in the indoor space. A model correcting part collates the temperature distribution estimated by the temperature distribution estimating part with the temperature at the measurement point acquired by the communication part, and corrects the analysis model based on a collation result.

  • Publication number: 20210301802
    Abstract: In a variable displacement compressor 100, transmitting member 116 transmits rotational motion of rotor 112 to swash plate 111 and supports swash plate 111. Guide member 117 guides inclining motion of swash plate 111 such that a top dead center position of piston 126 is maintained to be substantially constant. Members 116, 117 are separately formed at different portions on a rotor end face 112a. In the variable displacement compressor 100, first contacted member 118 contacted with transmitting member 116, and second contacted member 119 contacted with guide member 117, are separately formed at different portions on swash plate end face 111b. The transmitting member 116 and the first contacted member 118 extend on rotor 112 and swash plate 111, respectively, from a top dead center side region V1 to a bottom dead center side region V2 of the piston.

    Abstract: Attenuation of microwaves is reduced or prevented when vacuum windows are provided in microwave waveguides of a DNP-NMR probe. A DNP-NMR probe has an inner container and an outer container. The inner container has therein a sample tube containing a sample to which radicals are added. The outer container keeps a space between the outer container and the inner container in the outer container in a vacuum state. The outer container has an outer container waveguide that has a vacuum window at an inner end portion and guides microwaves. The inner container has a vacuum window facing the vacuum window of the outer container waveguide through vacuum, and guides microwaves transmitted from the outer container waveguide to the sample.

  • Patent number: 10778461
    Abstract: In an appliance control system, a receiver receives, from a terminal device used by a first user, an instruction for remotely controlling an appliance installed in a home. A determiner determines whether a second user is present in a location in which an appliance-to-be-instructed is installed. When it is determined that the second user is not present in a location in which the appliance-to-be-instructed is installed, an appliance controller controls the appliance on the basis of the instruction. On the other hand, when it is determined that the second user is present in the location in which the appliance-to-be-instructed is installed, the appliance controller does not control the appliance.
