  • Patent number: 10786836
    Abstract: A substrate processing method includes a chemical liquid supplying step of supplying a chemical liquid to a substrate, an elapsed period measuring step of measuring an after-the-end elapsed period, a recovery step of controlling the switching unit to be in a recovery guiding state, when, at a start of the chemical liquid supplying step, the after-the-end elapsed period is less than a predetermined first period, and a draining step of controlling the switching unit to be in a drain guiding state, in which the liquid led to the recovery space is led to the drain line, when, at the start of the chemical liquid supplying step, the after-the-end elapsed period is not less than the predetermined first period and then switching to the recovery guiding state based on establishment of a predetermined draining ending condition.

  • Patent number: 10597607
    Abstract: Provided is a method for producing a polyunsaturated fatty acid while preventing deterioration of a silver salt solution. A method for producing a composition comprising a polyunsaturated fatty acid, comprising: supplying an aqueous solution comprising a silver salt into a reaction vessel to contact the aqueous solution with a raw material solution comprising an alkyl ester of the polyunsaturated fatty acid; and collecting the aqueous solution comprising the silver salt which has been contacted with the raw material solution from the reaction vessel, wherein the supply of the aqueous solution comprising the silver salt into the reaction vessel and the collection of the aqueous solution comprising the silver salt from the reaction vessel are carried out concurrently with each other.

  • Patent number: 6115424
    Abstract: The information block that is sequentially extracted from an information sequence and that serves as a conversion unit is divided into a plurality of sub-blocks, Then, counting is performed of the information items number of at least one of "0" and "1" that is contained in each sub-block for each sub-block of a plurality of the thus-divided sub-blocks. Then, there is performed, according to the counted result that has been thus obtained, inversion yes/no determination of whether the original information contained in each sub-block should be inverted under the consideration of minimizing the difference between the number of codes "0", and the number of codes "1", contained in the code block as a whole.
