  • Publication number: 20200260671
    Abstract: Prior art technology has a problem in that when a plant is cultivated for a long period of time on a PVA film having its lower surface positioned in contact with a nutrient fluid, plant roots that have formed penetrate through the film. A plant cultivation system wherein the PVA film has an equilibrium degree of swelling in the range of from 125 to 250% as measured in water at 30° C. and has a loss tangent (tan ?) in the range of from 0.005 to 0.2 as measured in an equilibrium swollen state in water at 30° C., and a method for cultivating a plant by using this plant cultivation system. Plant cultivation can be performed for a long period of time while avoiding infection by bacteria and the like causative of plant diseases. Therefore, the present invention is useful in, e.g., agriculture and the manufacture of pharmaceuticals.

  • Patent number: 10113499
    Abstract: An ECU has a fuel pressure sensor that detects fuel pressure inside of a common rail. The ECU detects the fuel pressure at a predetermined frequency and calculates a drop amount of the fuel pressure in accordance with fuel injection by fuel injectors based on the detected fuel pressure. The ECU acquires a fluctuation amount of a fuel injection amount of each of the fuel injectors based on the drop amount of the fuel pressure and learns an injection characteristic of each of the fuel injectors, the injection characteristic indicating a correlation between the fuel injection amount and the fluctuation amount of the fuel injection. In a case in which a detection timing of the fuel pressure is within a fuel injection period of a predetermined fuel injector, the ECU disallows the learning of the injection characteristic using the fuel pressure detected in the fuel injection period.
