  • Publication number: 20230028756
    Abstract: An electrode manufacturing apparatus according to one aspect of the present disclosure is configured to discharge a liquid to form a resin layer or an inorganic layer on an electrode substrate which is being conveyed in a predetermined direction. The electrode manufacturing apparatus includes a detector, a liquid discharger provided downstream of the detector in the predetermined direction and configured to discharge the liquid to form the resin layer or the inorganic layer, and a controller configured to control a discharge condition of the liquid discharger. Points where a property varies are present on the electrode substrate along a direction intersecting the predetermined direction. The detector outputs pieces of detection information obtained by detecting one of the points in time series, and the controller controls the discharge condition of the liquid discharger based on combined detection information obtained by combining the pieces of detection information.

  • Patent number: 10723158
    Abstract: A line head type liquid discharge apparatus includes a treatment liquid applying device, a first discharging device, a heating device, and a second discharging device. The treatment liquid applying device applies a treatment liquid to a non-permeable base material. The first discharging device discharges a first ink containing an organic solvent onto the non-permeable base material to which the treatment liquid has been applied. The heating device heats, with an infrared ray, the non-permeable base material onto which the first ink has been discharged. The second discharging device discharges a second ink containing an organic solvent onto the non-permeable base material heated by the heating device. A content ratio of the organic solvent contained in the first ink is higher than a content ratio of the organic solvent contained in the second ink.
