  • Patent number: 10322958
    Abstract: A sludge dewatering system includes: a concentration apparatus that concentrates sludge while conveying the sludge on a top surface of a filter body; and a dewatering apparatus that subjects the sludge discharged from the concentration apparatus to pressure dewatering. The concentration apparatus includes: a filtering unit that subjects the sludge, which has been added with a first chemical agent, to gravity filtration; a chemical feeder that adds a second chemical agent to the sludge conveyed in the filtering unit; and a moving mechanism that moves the sludge, which has been added with the second chemical agent, in a direction intersecting a conveyance direction of the filter body.

  • Publication number: 20190150292
    Abstract: A circuit forming method where a metal ink is ejected to a planned formation position of a first wiring at an upper face of a base material. Then, the metal ink is baked, and first wiring is formed. Further, a planned connection section of the first wiring and a second wiring is unbaked. The metal-ink is ejected over an upper face of the unbaked metal ink and a planned formation position of the second wiring at the upper face of the base material. Since the wettability of the upper face of the unbaked metal ink and the wettability of the upper face of the base material are equal to each other, the ejected metal ink ejected and the unbaked metal ink are not separated from each other, so that it is possible to properly connect the first wiring and the second wiring to each other.

  • Patent number: 10212823
    Abstract: To form wiring on circuit board and conductor body, metal ink containing metal particles is dispensed by inkjet head straddling the circuit board and the conductor body. Then, a laser is applied by laser emitting device to the dispensed metal ink. The metal ink to which the laser is applied is baked and wiring is formed. A laser corresponding to the laser emission amount per unit of area based on the material of the circuit board, which is resin, is applied to the metal ink on the circuit board, and a laser corresponding to the laser emission amount per unit of area based on the conductor body is applied to the metal ink on the conductor body. The metal ink on the circuit board and the metal ink on the conductor body is baked appropriately, and wiring is formed appropriately straddling the circuit board and the conductor body.
