The container body contains developer and has a discharge port. The rotary stirrer includes a rotary support and rotates about the rotary shaft to stir and transport the developer. The rotary support includes a base end rotatable integrally with the rotary shaft, a free end spaced away from an inner wall of the container body, and a holding surface provided at the free end or at a position shifted toward the rotary shaft away from the free end. The holding surface is parallel to or inclined relative to a rotation direction of the rotary support. The flexible blade includes a base end portion held on the holding surface and a distal end to contact the inner wall and transport the developer to the discharge port. | 09-17-2015 |
20160070208 | DEVELOPING UNIT, PROCESS CARTRIDGE, AND IMAGE FORMING APPARATUS - A developing unit includes a developer bearer to bear developer on a surface thereof, first and second developer conveyors each having a spiral blade mounted on a rotary shaft thereof parallel to a rotary axis of the developer bearer to convey developer in opposite directions to each other. A developer drain hole is provided at a given height in a side wall of a second developer conveyance channel to face a communication opening across the second developer conveyor. The first developer conveyor rotates in a direction with its spiral blade rising between the rotary shaft of the first developer conveyor and the communication opening. Rotational phases of the first developer conveyor and the second developer conveyor are fixed and synchronized with each other to weaken momentum of developer flow generated by the first developer conveyor toward the developer drain hole via the second developer conveyor. | 03-10-2016 |

20080256937 | FLUID HEATING DEVICE AND EXHAUST GAS PURIFYING APPARATUS - A fluid heating device includes a heating part and a plurality of heat transfer sections. The heating part is disposed in a fluid stored in a container and is elongated in an axial direction for heating the fluid between a lower portion and an upper portion of the container by being supplied with electricity. The heat transfer sections arranged along the axial direction of the heating part. Each of the heat transfer sections has a plate shape extending from the heating part to a radial outside of the heating part approximately perpendicularly to the axial direction of the heating part. | 10-23-2008 |
20080260597 | Reducing gas generator and solid reductant SCR system having the generator - A reducing gas generator generates reducing gas including ammonia. The generator includes a solid reductant and a heat-generating portion. The solid reductant is formed in a columnar shape. A cross-sectional surface of the solid reductant has a constant shape and is perpendicular to a central axis of the solid reductant. The heat-generating portion includes a heat-generating surface opposed to a lower surface of the solid reductant in a vertical direction thereof and in contact with an entire region of the lower surface, and a heating element that heats the heat-generating surface when energized, so that the solid reductant is heated and decomposed to generate the reducing gas. | 10-23-2008 |
20090065609 | INJECTOR - An injector includes a nozzle hole formation part having a nozzle_hole formation area and nozzle holes in at least one circle shape in the formation area. The formation area is divided into central and peripheral regions by a predetermined circle, the former inward from the predetermined circle and the latter in the periphery of the central region. The nozzle holes include outputting nozzle holes in the peripheral region and at least one cooling nozzle hole in the central region. Fuel through the outputting nozzle holes contributes to engine output. A smaller amount of fuel than a fuel amount through the outputting nozzle hole is injected through the cooling nozzle hole to cool the central region. A ratio of a second total fuel amount through the cooling nozzle hole to an overall total fuel amount ranges from 0.05 to 0.37. | 03-12-2009 |
20090108102 | INJECTOR - An injector includes a valve body, a needle valve, and a thermal expansion member. The valve body includes an internal space and a bottom portion having a nozzle hole. One end side of the space is covered with the bottom portion. The needle valve is accommodated in the space such that a fuel passage leading to the hole is formed between an inner surface of the valve body and an outer surface of the needle valve. The passage is opened or closed with respect to the hole by movement of the needle valve, so fuel injection is started or stopped. The inner surface of the bottom portion is opposed to a one end surface of the needle valve. The member is attached on the one end surface. The member is made of a material having a larger coefficient of thermal expansion than a material of the needle valve. | 04-30-2009 |
20090191074 | ELECTRICALLY POWERED PUMP - An electrically powered pump includes a pump arrangement that pumps a liquid, and an electric motor arrangement that has a stator and a rotor that are installed on a passage through which the liquid pumped by the pump arrangement flows. At least one of the stator and the rotor has a winding wire that generates a magnetic field when it is energized to rotate the rotor with respect to the stator to drive the pump arrangement. The winding wire has a conductive body through which an electric current passes and an insulation body that insulates the conductive body. The conductive body is made of a material predominantly composed of carbon. Thereby, the liquid pumped by a pump arrangement is prevented from corroding the winding wire. | 07-30-2009 |
20100224706 | FORMATION METHOD OF WATER REPELLENT LAYER AND INJECTOR HAVING WATER REPELLENT LAYER - A formation method for forming a water repellent layer on a surface of a metal substrate forms asperities on a surface of a metal basis material of the metal substrate by irradiating the metal basis material with plasma ions. The formation method forms an alloy from atoms of a metal of the metal basis material and the plasma ions. The formation method forms the asperities with portions of the metal basis material, which are not etched due to the alloy, and portions of the metal basis material, which are not alloyed but are etched. The formation method forms the water repellent layer by forming the asperities. | 09-09-2010 |
20110147493 | METHOD FOR FORMING PERIODIC STRUCTURE AND FUEL INJECTION SYSTEM HAVING THE PERIODIC STRUCTURE - A method is for forming a periodic groove arrangement. According to the method, a base material made of metal is provided. Furthermore, the periodic groove arrangement, which includes a plurality of periodic grooves, is formed on a surface of the base material by irradiating and scanning the surface of the base material with a pulsed laser. A fuel injection system includes a nozzle hole forming part and the periodic groove arrangement formed by the method. The nozzle hole forming part includes a nozzle hole, which passes through the nozzle hole forming part and through which fuel is injected. The periodic groove arrangement is formed on an outer surface of the nozzle hole forming part. | 06-23-2011 |
