Abstract
A corrosion prediction device that predicts corrosion indicating the degree to which a metal will corrode in an environment, the device including a storage unit which stores a soil sample that simulates the environment and an electrode unit and has a function of repeatedly performing water supply and drainage with respect to the soil sample; the electrode unit including at least one type of metal pieces; a measurement unit that measures, based on change in water content in the environment in one cycle, a corrosion rate of the metal pieces or a value proportional to the corrosion rate of the metal pieces during the change; a calculation unit that integrates the corrosion rate or a value proportional to the corrosion rate over time and calculates an amount of corrosion or a value proportional to the amount of corrosion; and a prediction unit that determines a constant value of K of the power law and a constant value of n of the power law using a difference between the amounts of corrosion or the values proportional to the amounts of corrosion in different periods.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
