  • Publication number: 20220236225
    Abstract: [Object] To provide an arithmetic device, an arithmetic method, and a gas detection system that are capable of easily correcting deterioration over time of a detection element. [Solving Means] The arithmetic device includes a calculation unit. The calculation unit calculates a correction coefficient from a detection element that causes a resonant frequency change by adsorption of gas on the basis of a resonant frequency change amount associated with a humidity change of the detection element in a degraded state and a resonant frequency change amount associated with a humidity change of the detection element in an initial state that was acquired in advance, and corrects the resonant frequency change amount of the detection element in the degraded state by using the correction coefficient.

  • Patent number: 8882356
    Abstract: A horizontal shaft type rotary machine capable of simply feeding oil into thrust bearing devices. Leak oil introduction is provided in the circumferential end parts of thrust bearing devices, for introducing leak oil of lubrication oil from horizontal type slide bearing devices onto slide surfaces of the thrust bearing devices. With this configuration, the thrust baring devices can be lubricated with the use of leak oil of lubrication oil from the horizontal type slide bearing devices, and as a result, it is possible to eliminate the necessity of an oil feed system exclusively used for the thrust bearing devices, thereby it is possible to simplify the pipe line arrangement of the oil feed system and the control of oil feed quantity.
