  • Patent number: 10513119
    Abstract: An inkjet recording method includes applying an aqueous ink and a reaction liquid for increasing the viscosity of the ink to an ejection target medium to form an ink image thereon. The ink image is then subjected to a liquid absorbing treatment using a porous body having a liquid absorbing surface. In the liquid absorption treatment, the liquid absorbing surface is brought into contact with the ink image to absorb at least a part of the liquid component from the ink image by the porous body and the porous body is used repeatedly while it is sometimes carried out from the liquid absorption treatment region for cleaning. Contact information of the porous body including the number of contact times and a contact pressure in each contact is stored and the gas permeability state of the porous body is evaluated by using such contact information.

In an inverter of the electric compressor, a snubber circuit 21 comprising a resistor R and a capacitor C is provided between input/output terminals 20 of a power source and a switching element 18. The snubber circuit 21 is formed by surface mounting a resistive element constituting the resistor R and a capacitor element constituting the capacitor C on a power board 16. A leakage current from a motor 19 is thus restrained and radio noise is reduced. The resistive element and the capacitor element constituting the snubber circuit 21 are preferably surface mounted on the power board 16 on the side opposite to the side on which a control circuit board is arranged.
