  • Publication number: 20190170376
    Abstract: [Problem to be Solved] To provide a gas humidity regulating method and a regulator that can regulate a temperature during humidity control and improve humidity-control efficiency. In an air humidity regulating method for gas subjected to treatment, a first medium 22 is caused to flow onto a heat exchanging pipe 17 of a gas-liquid contact part 18 in a dehumidifier 11; meanwhile, a second medium 24 is passed through the heat exchanging pipe 17. In this state, air is fed into a gas-liquid contact case 13 from an inlet port 14 and gas-liquid contact is made by the first medium 22 on the gas-liquid contact part 18 so as to absorb water content from the air into the first medium 22. The first medium 22 contains an ionic liquid having high absorbency. The temperature of the first medium 22 is regulated by the second medium 24. After that, treated air is discharged from an outlet port 15 of the gas-liquid contact case 13.

  • Publication number: 20190095474
    Abstract: A table relation analysis assisting apparatus analyzes a relation between pieces of data in a certain column (external key) astride tables in a relational database. The apparatus analyzes a relation between tables and holds inter-table relation analysis information in which tables, pieces of data in the tables being in a one to one relation or a plural to one relation, are defined as one table group. In the apparatus, an analysis result display unit provides a display in such a form that one or more tables in a relational database are contracted into a table group. The display unit displays table groups in such a form that which of a one to one relation or a plural to one relation a relation between pieces of data included therein is astride tables can be viewed.
