  • Patent number: 10983231
    Abstract: A computer calculates a change amount of a total number of electrons from an observation start time in the ionosphere between an observation station and a satellite based on observation data of a signal received from the satellite by the observation station on the ground. The computer estimates the change amount of the total number of electrons to be calculated next based on the time change of the change amount of the total number of electrons from the observation start time in the ionosphere and calculates a difference (estimation error) between the estimated change amount of the total number of electrons and the actually calculated change amount of the total number of electrons. The computer calculates a correlation value between the estimation error calculated for each observation station and the estimation error calculated for a predetermined number of the observation stations in the vicinity of each observation station.

  • Patent number: 10721851
    Abstract: A cut and clinch device is provided with a pair of slide bodies, unit main body that holds the pair of slide bodies so as to be capable of moving towards and away from each other, and pitch changing mechanism that changes an insertion hole spacing distance that is a distance between insertion holes formed in the pair of slide bodies. Also, the leaded component held by the component holding tool is imaged by the imaging device before the leads are inserted into the through-holes of the board, and based on the imaging data, the lead spacing distance that is the distance between the pair of leads of the leaded component is calculated. Then, the pair of slide bodies are moved towards or away from each other such that the calculated lead spacing distance and the insertion hole spacing distance are the same.
