  • Publication number: 20200033390
    Abstract: One preferable aspect of the present invention is a state detecting system which detects a state of a machine device based on a detection signal from a detecting element provided to the machine device, and is the state detecting system which includes a non-normal time rate detecting unit which detects a rate or a value as a non-normal time rate, the rate being a rate of an integration value of a time during which an amplitude of the detection signal exceeds a predetermined normal amplitude within a predetermined time, and the value being physically equivalent to the rate.

  • Patent number: 9856269
    Abstract: A method for producing a highly pure PMDA comprises at least the following steps: (1) a step of preparing a raw material solution by dissolving a raw material of a pyromellitic dianhydride in an acetic acid solvent, (2) a step of preparing a precursor pyromellitic dianhydride by recrystallizing the pyromellitic dianhydride in the prepared raw material solution and separating the acetic acid solvent, (3) a step of performing a degassing treatment on the precursor pyromellitic dianhydride by stirring the precursor pyromellitic dianhydride in a fluidized state while heating under reduced-pressure conditions, and (4) a step of taking out the pyromellitic dianhydride subjected to the degassing treatment.
