  • Patent number: 11124869
    Abstract: A pre-drying processing liquid containing a sublimable substance that changes to gas without passing through to a liquid and a solvent in which the sublimable substance dissolves is supplied to a front surface of a substrate on which a pattern has been formed. Thereafter, the solvent is evaporated from the pre-drying processing liquid on the front surface of the substrate to thereby form a solidified body containing the sublimable substance on the front surface of the substrate. Thereafter, the solidified body is sublimated and thereby removed from the front surface of the substrate. A value acquired by multiplying a ratio of the thickness of the solidified body to the height of the pattern by 100 is greater than 76 and less than 219.

  • Patent number: 10803756
    Abstract: A flight controlling apparatus includes an information acquiring unit, a point searching unit, a determining unit, and a route changing unit. The information acquiring unit acquires location information of a factor on a ground that possibly influences safety of an aircraft in landing. The point searching unit searches for one or more landing candidate points to prepare for an expected abnormality in the aircraft in flight, on the basis of the location information. The determining unit determines whether the one or more landing candidate points are selected to prepare for the expected abnormality. The route changing unit changes a flight route of the aircraft to cause the one or more landing candidate points to be obtained to prepare for the expected abnormality in a case where the determining unit determines that no landing candidate point is selected to prepare for the expected abnormality.
