A mold includes a rotatable portion, a frame portion, a first and second portion, and a production unit. The rotatable portion has a plurality of surfaces and a plurality of forming portions. The plurality of surfaces is each provided with one of the plurality of forming portions, each having the same shape. The frame portion rotatably supports the rotatable portion. The first portion defines a cavity by coming into contact with one surface of the plurality of surfaces by clamping the mold. The second portion comes into contact with another surface of the plurality of surfaces different from the one surface by clamping the mold. The production unit attached to the frame portion.

Mold, method of producing product, method of producing image forming apparatus, and non-transitory computer-readable recording medium

A steerable catheter driven by a robotic controller comprises: a catheter body having a catheter tip and tool channel which spans from a proximal end of the catheter body and through the catheter tip along a catheter axis. The catheter tip includes a ramp-like surface formed inside part of the tool channel diameter. The ramp-like surface is an inclined flat surface formed at an angle with respect to a plane parallel to the catheter axis, such that the angle increases as the ramp-like surface spans from distal end towards the proximal end of the catheter tip. A housing mechanism permanently attached to an imaging device is configured to lock the imaging device to the ramp-like surface so as to prevent rotation of the imaging device with respect to the tool channel and/or prevent twisting of the catheter tip with respect to the imaging device.

Antitwist mechanism for robotic endoscope camera

An assembling apparatus that has a mold in which a second unit opposes a first unit and that is configured to assemble an assembled product from a plurality of parts. The first unit includes first, second, and third movable portions, which comprise, respectively, a plurality of first forming portions, a plurality of second forming portions, and a plurality of third forming. The second unit comprises a fourth movable portion, a fourth forming portion, a fifth forming portion, a sixth forming portion, and a plurality of assembling portions. The fourth movable portion is configured to move so as to switch at least one assembling portion opposed to at least one first forming portion, at least one other assembling portion opposed to the at least one second forming portion, and at least one remaining assembling portion opposed to at least one third forming portion.

Method of producing assembled product and assembling apparatus

A method of manufacturing a developer container including a frame configured to define a developer containing portion, a first electrode, and a second electrode arranged on a surface of the frame and having a surface opposed to the first electrode, a developer amount in the developer containing portion being detected based on a capacitance between the first electrode and the second electrode, the method including: holding a conductive resin member constituting the second electrode on a mold configured to mold the frame, a surface of the conductive resin member being in contact with a surface of the mold configured to mold a surface of the frame on a side of the developer containing portion; injecting a resin to be formed into the frame, into the mold on which the conductive resin member is held; and curing the resin to form the frame to which the second electrode is fixed.

Method of manufacturing developer container, developer container, developing apparatus, process cartridge, and image forming apparatus

A molded resin product for use with an image forming apparatus includes: a base portion formed of a resin material; a positioning portion provided on the base portion; and a movable member formed by injection molding so as to be movable relative to the base portion. When the molded resin product is connected to a connection part, the positioning portion positions the molded resin product and the connection part relative to each other, and the movable member is contactable to a contact portion of the connection part.

Image forming apparatus, molded resin product for use with the image forming apparatus, and cartridge

A fixing portionfor suppressing movement of a developer bagwhen the developer bagis unsealed by moving a sealing memberis provided. By this, unsealing becomes easy.

Developer accommodating container, developer accommodating unit, process cartridge, and electrophotographic image forming apparatus

Method of manufacturing developer container

A process cartridge includes a drum unit configured to rotatably hold a photosensitive drum, a developing unit that is assembled in such a manner as to be rotatable relative to the drum unit and includes a developing roller, gap maintaining members provided to the photosensitive drum or the developing roller on both end portions of the photosensitive drum in an axial direction, and urging members configured to bias the developing unit toward the drum unit. The urging members are respectively disposed on outer sides of the gap maintaining members disposed at both end portions in the axial direction. The drum unit or the developing unit includes an electric contact portion configured to come into contact with an electric contact of an image forming apparatus when the process cartridge is attached to the image forming apparatus, the electric contact portion being disposed between the gap maintaining members in the axial direction.

Process cartridge and image forming apparatus

A developer accommodating unit for accommodating a developer for image formation. A flexible container includes a developer accommodating portion for accommodating the developer and an opening for permitting discharge of the developer. The flexible container also includes a superposed multi layer sheet structure portion for forming the developer accommodating portion. A sealing member seals the opening and an unsealing member moves the sealing member to unseal the opening. A frame that accommodates the flexible container, the sealing member, and the unsealing member includes a fixing portion for fixing the flexible container. A fixed portion fixed to the fixing portion is provided at the superposed multi layer sheet structure portion of the flexible container, and an interlayer bonding portion between the superposed layers is provided between the fixed portion of the multi layer sheet structure portion and the developer accommodating portion.

Developer accommodating unit, process cartridge, and electrophotographic image forming apparatus

A developing cartridge includes: a flexible developer bag, provided with an opening and provided in a frame, for accommodating a developer; and an acting member contactable to the developer bag. The developer bag is fixed to the frame at its upper portion. The developer bag is swingable by contact with the acting member.

Developing cartridge, process cartridge and image forming apparatus

A developer accommodating container for accommodating developer for image formation. The developer accommodating container includes a first flexible member having a folded shape and a second flexible member for forming a space for accommodating the developer by covering a part of the first flexible member. The first flexible container and the second flexible container form an injection opening for permitting injection of developer into the space. As seen from an injection direction, the folded shape has a recess.

Developer accommodating container with flexible members forming injection opening

A developer accommodating unit for accommodating a developer includes: a flexible container provided with an opening for permitting discharge of the accommodated developer; a sealing member for sealing the opening and for exposing the opening by being moved in a direction crossing a longitudinal direction of the developer accommodating unit; an unsealing member, mounted to the sealing member, for moving the sealing member; a frame including a fixing portion for fixing the flexible container; and a bonding portion for bonding an end portion of the sealing member and a periphery of the opening. The bonding portion includes a projected portion or recessed portion in a plane of the bonding portion as at least a part thereof, in an upstream side or a downstream side of the opening with respect to an unsealing direction of the opening.
