摘要:
Disclosed herein is a technique of removing metal contained in a solution through chelation, which makes it possible to preclude undesired aggregation and permit effective aggregation through an aggregating process. A surface active agent containing a hydrophobic group, a hydrophilic group and a chelating group is added to the solution to be processed, and subsequently an aggregating process is carried out. The chelating group chelates metal, the hydrophilic group prevents undesired aggregation, and the hydrophobic group is effectively aggregated in the aggregating process. Various uses are possible by selecting the charge of ligand.

A semiconductor device includes a semiconductor chip of a multilayer wiring structure having an insulating film formed on a surface thereof, multiple electrode pads formed at a central part and an outer peripheral part of the insulating film, and multiple protective metal layers formed respectively on the electrode pads. The semiconductor device also includes a substrate having the semiconductor chip mounted thereon and including multiple substrate terminals formed on a surface thereof respectively in positions corresponding to the electrode pads. The semiconductor chip is mounted on the substrate by connecting a stud bump to a solder bump. The stud bump is formed on any one of each of the protective metal layers and each of the substrate terminals and the solder bump is formed on the other one of each of the protective metal layers and each of the substrate terminals.

A developer supply container is mountable to a developer receiving apparatus including a driving gear, wherein the container mounted to the apparatus is settable to a set position by a rotating operation of the container in a setting direction by an operator, and includes a substantially cylindrical portion; a developer discharging opening provided on a surface of the cylindrical portion; a developer feeding member provided in the cylindrical portion; a drive receiving member to engage with the driving gear for rotating the developer feeding member; and a regulating portion for regulating a mounting attitude of the cylindrical portion so as to prevent engagement between the drive receiving member and the driving gear. A rotating operation of the cylindrical portion toward a set position about a center of the cylindrical portion in a setting direction engages the drive receiving member with the driving gear.

A toner container detachably mountable to an image forming apparatus, includes a main body for containing toner; a sealing portion for sealing the toner discharge opening; locking projections for snap-fitting engagement with holes provided in a cylindrical member of an image forming apparatus, wherein the projections receive from the cylindrical member unsealing forces for unsealing the toner discharge opening by a relative movement between the sealing portion and the toner container, wherein a number of the locking projections is larger than a number of ribs provided between the holes of the cylindrical member.

A developer supply container is mountable to a developer receiving apparatus including a driving gear, and includes an inner body and an outer body configured and positioned to open and close an opening formed on a peripheral portion of the inner body; a developer feeding member provided in the inner body; a drive receiving member engageable with the driving gear for rotating the developer feeding member; and a regulating portion for regulating a mounting attitude of the container to prevent an engagement between the drive receiving member and the driving gear. Upon mounting the container, the drive receiving member is revolvable, with manual rotation of the outer body, in a setting direction around an axis of the outer body to a set position where the drive receiving member engages with the driving gear. The drive receiving member is loaded to retard the rotation thereof about the axis.

A developer supply container is mountable to a developer receiving apparatus including a driving gear, and includes a developer discharging opening; a feeding blade for feeding the developer toward the opening when the container is positioned at a developer discharging position; a drive receiving gear engageable with the driving gear for rotating the feeding blade; a regulating projection for regulating a mounting attitude of the container to prevent engagement between the drive receiving and driving gears. Upon mounting the container, the drive receiving gear is revolvable, with manual rotation of the container, about a rotation center of the container to a set position where the drive receiving gear engages with the driving gear; and a load applier for applying a load to the drive receiving gear to rotate the container from the set position to the discharging position by the rotational force received by the drive receiving gear.
摘要:
If a user is not familiar with the operation for the developer supply container, the rotating operation for the developer supply container may be insufficient, so that developer supply container does not reach a predetermined operating position, with the result of abnormal developer supply. by increasing a rotation load of a second gear 6 which is in an operable connection with a drive gear member 12 of the developer receiving apparatus 10 by a function of a locking member 7, the developer supply container 1 mounted to the developer receiving apparatus 10 is rotated toward the supply position. After the developer supply container 1 rotates to the supply position, the locking by the locking member 7 is released, by which the rotation load applied to the second gear 6 is reduced, so that drive transmission, thereafter, to the feeding member 4 for developer supply is smooth.
摘要:
In the case that a developer supply container is provided with a feeding portion for feeding a developer by receiving a rotational force and a pump portion for discharging the developer by reciprocation, and the rotational force and a reciprocating force are received from a main assembly side of an image forming apparatus, there is a liability that a driving connection is not properly established between a portion of the developer supply container for receiving the reciprocating force and a portion of the main assembly side for applying the reciprocating force.The developer supply container is provided with a drive converting mechanism for converting the rotational force received from the main assembly side to a force for operating a volume changing type pump.
摘要:
A developer supply container detachably mounts to a developer receiving apparatus and supplies a developer by rotation and includes a regulation portion for determining whether or not the developer supply container should be mounted by being regulated by a regulation member of the developer receiving apparatus and a lead portion which is movable relative to a guiding portion of the developer receiving apparatus so that the regulation member and the regulation portion are in phase with each other. When the developer supply container is inserted in a direction of a rotation axis thereof, a phase of the regulation portion with the regulation member is determined by movement of the lead portion of the developer supply container relative to the guiding portion of the developer receiving apparatus and then is regulated by the regulation member.
