  • Publication number: 20180170343
    Abstract: A controller controls a valve device for opening and closing of a passage to control a flow of evaporative fuel evaporating and flowing from a fuel tank. The valve device includes a valve body housed in the passage to open and close the passage, a biasing member biasing the valve body to close the passage, and a driver driving the valve body to open the fuel passage. The controller includes a detector detecting load of the driver and a determiner to determine the position of the valve body. The determiner determines that the passage is open when a magnitude of the change of the driver load is equal to or greater than a threshold value. The controller accurately detects an open valve position without detecting an internal pressure change of the fuel tank.

  • Patent number: 9975331
    Abstract: An inkjet printer comprising a plurality of nozzles, a plurality of pressure chambers, a plurality of diaphragms, a plurality of piezoelectric elements, and a controller. Each of the plurality of diaphragms is deflected between a first state and a second state. The controller is configured to control voltage application to each of the plurality of piezoelectric elements. When a diaphragm is in the first state, the controller applies a first voltage so that the diaphragm is substantially flat; and when the diaphragm is in the second state, the controller applies a second voltage. The controller is configured to control the voltage such that a pressure chamber ejects an ink droplet from the corresponding nozzle in response to the deflection of the diaphragm reverting from the second state to the first state.
