  • Patent number: 10310409
    Abstract: According to one embodiment, a cartridge is provided with a case and a transportation member. The case includes a first chamber, a second chamber, and a passage. The first chamber communicates with a discharging port and accommodates a developing agent. The second chamber is positioned distant from the discharging port compared to the first chamber and accommodates a toner. The passage allows the discharging port to communicate with the second chamber. The transportation member transports the toner, which is supplied to the passage from the second chamber, toward the discharging port.

  • Patent number: 9970827
    Abstract: A fuel temperature estimation device that can improve the estimation accuracy of a fuel temperature in each part of a fuel channel, is provided. In the invention, the fuel temperature estimation device estimates the fuel temperature of each part of the fuel channel in a vehicle (for example, an injection nozzle, a pressure accumulator, a high-pressure pump), and includes a flow rate measuring device that measures a fuel flow rate of a fuel return system of the fuel channel and a controller. The controller includes a fuel temperature correction unit that corrects an estimated fuel temperature in a fuel injection system based on the fuel flow rate of the fuel return system, and has a function of estimating the fuel temperature using the fuel flow rate of the fuel return system as a parameter.

  • Patent number: 9593616
    Abstract: An exhaust pipe fuel injector capable of preventing fuel from remaining in a fuel supply system and thus capable of preventing the fuel supply system from being blocked due to carbonization of the fuel, is provided. The exhaust pipe fuel injector includes: a fuel injection nozzle that injects the fuel into an exhaust pipe; a supply pipe through which a mixed fluid of the fuel and air is supplied into the fuel injection nozzle; and a control unit. The control unit has a function of continuing combustion until no fuel remains in the inside of the supply pipe during regeneration of a diesel particulate filter.
