A work machine having working equipment includes a power source that outputs a driving force for operating the working equipment, a controller, and a solenoid valve controlled by the controller. When it is determined that an abnormality has occurred in the power supply circuit connecting the controller and the solenoid valve, the controller outputs a command for controlling the power source so as to limit an operation of the working equipment.

Work machine and method for controlling work machine

A cartridge attachable to an apparatus main body of an image forming apparatus, the apparatus main body having a restricting portion and to which the cartridge is mounted by being moved from a unmounted position to a mounting-completed position in a first direction, the cartridge includes a developer container provided with a supply port, and a shutter movable between an opening position for opening the supply port and a closing position for closing the supply port, having a restricted portion, and configured to be in the closing position when the cartridge is in the unmounted position and be in the opening position when the cartridge is in the mounting-completed position, wherein a movement of the shutter in a second direction perpendicular to the first direction is restricted by an engagement between the restricting portion and the restricted portion when the cartridge is in the mounting-completed position.

Cartridge and image forming apparatus

A developer container includes a frame having a developer storage chamber which stores a conveying member, a developing chamber in which a developer bearing member and a supplying member are arranged, a partition partitioning the developer storage chamber and the developing chamber and provided with a first opening, and a second opening which connects an interior of the developing chamber and an exterior of the frame. A filter allows passage of air and restricts passage of the developer, with the filter being fixed to the frame so as to cover the second opening. The conveying member is deformable such that the developer is conveyed from the developer storage chamber to the developing chamber via the first opening by deformation of the conveying member being released, and the conveying member conveys the developer such that the developer passes above the supplying member.

Developer container, process cartridge, and image forming apparatus

A plurality of electromagnetic proportional control valves are configured to control a pressure of a pilot oil generated by operation of a first control lever device and a second control lever device and, in accordance with the pressure of the pilot oil, adjust a flow rate of a hydraulic oil supplied to hydraulic cylinders. The plurality of electromagnetic proportional control valves are divided into a first valve block including at least one of the electromagnetic proportional control valves and a second valve block including at least one of the electromagnetic proportional control valves. The first valve block and the second valve block are arranged to be separated from each other.

Work machine

A unit includes: a conveying member that conveys developer; a frame that stores the developer and includes a first chamber storing the conveying member, a second chamber, a first opening connecting the first chamber and the second chamber, and through which the developer is passed, and a second opening connecting the interior of the second chamber and the exterior of the frame in an orthogonal direction that is orthogonal to a direction of a rotation axis line of the conveying member; and a filter that allows air to pass the second opening and restricts the developer from passing the second opening, and is fixed to the frame, wherein the frame is displaceable with respect to an apparatus main body in a state where the unit is attached to the apparatus main body, and the filter is displaced with respect to the apparatus main body by the displacement of the frame.

Unit having a developer conveying member and a filter for a chamber

A method for remanufacturing a cartridge from a source cartridge, wherein the source cartridge includes a first unit and a second unit, the first unit including a first memory unit having a first electrode and a first storage element electrically connected to the first electrode. The method includes removing the first memory unit from the first unit, attaching a second electrode of a second memory unit to the first unit, and attaching a second storage element of the second memory unit to the second unit. The second electrode and the second storage element are connected by a connecting member so that when the second unit moves relative to the first unit, electrical connection between the second electrode and the second storage element is maintained, and the second electrode is electrically connected to a main body electrode of an information apparatus.

Cartridge remanufacturing method and cartridge

A developer container includes a developer bearing member for bearing developer, a conveying member which conveys the developer, and a frame. In the frame, a partition partitions a developer storage chamber and a developing chamber and includes a first opening which connects the developer storage chamber with the developing chamber, and a second opening which connects an interior of the developing chamber and an exterior of the frame. A sealing member suppresses leakage of the developer from between the frame and the developer bearing member, and a filter allows passage of air through the second opening and restricts passage of the developer through the second opening. The conveying member is deformable such that the developer is conveyed from the developer storage chamber to the developing chamber via the first opening by deformation of the conveying member being released.

A developing unit includes a developer bearing member, a container, an end seal, a sheet, and a backup member. The container contains a developer. The container has an opening for supplying the developer to the developer bearing member. The end seal is disposed between the developer bearing member and the developer container. The end seal is disposed at an area of the container outside a longitudinal end of the opening. The sheet seals a gap between the developer bearing member and the container. One widthwise end of the sheet is fixed to the container. The other widthwise end is in contact with the developer bearing member. A longitudinal end of the sheet includes a sandwiched portion between the end seal and the developer bearing member. The backup member is provided in an area facing a surface of the sheet opposite to a surface in contact with the developer bearing member.
