  • Patent number: 12036488
    Abstract: A filtration device efficiently sizes removal of unnecessary substances adhering to and deposited on a filter medium of a filter element during filtration and backwashing (cleaning) from target (non-filtered) substances. The filter element captures substances in a fluid on one surface of a filter medium. The captured substances are separated from the filter medium during backwashing. A brush moves relative to the one surface of the filter medium and assists in separating the captured substances and sifting during the relative movement. The backwashing starts when a differential pressure between both surfaces of the filter medium exceeds a predetermined value, or the like while performing the filtration, and returns to filtration after the differential pressure is eliminated or after a predetermined time elapses. The brush sifts the unnecessary substances from the captured substances and passes the removal to the other surface side during the filtration.

  • Patent number: 11958471
    Abstract: A four-wheel drive vehicle includes: a drive-power distribution device for distributing a drive power from an engine to main and auxiliary drive wheels with a drive-power distribution ratio between the main drive wheels and auxiliary drive wheels; and a control apparatus for controlling an electric motor such that the drive-power distribution ratio becomes a target distribution ratio value, by setting an electric-current command value for driving an electric motor. The control apparatus is configured, in a drive-power transmitted state in which the drive power is transmitted to the drive-power distribution device, to execute a command-value reduction control operation for causing the electric motor to be driven with the electric-current command value being set to a value smaller than in a drive-power non-transmitted state in which the drive power is not being transmitted to the drive-power distribution device.

  • Patent number: 8960034
    Abstract: In a vehicle drive device, a response to a range change request, during which the drive wheels are rotated in a low or high range, can be smoothly and quickly completed without using a synchronous engaging mechanism. When the range change is requested when the drive wheels are rotated in the low range or in the high range, the control devices disengage a clutch sleeve from a currently engaged gear piece so as to establish a neutral range, and control an output rotational speed of the motor generator such that a difference between an input rotational speed and an output rotational speed of the transmission mechanism is set to be zero, or be equal to or less than a predetermined value. After that, the control devices cause a connection processor to slide the clutch sleeve to be connected to a connection target gear piece.
