    • A vacuum casting apparatus of the type wherein a gate mechanism (12 and 10) is closed to form a seal. The interior of a cavity (6) is evacuated by a vacuum pump. The side of the gate mechanism (12 and 10) opposite to the cavity is filled with molten metal. The gate mechanism includes a ring-shaped groove (10e) having a V-shaped cross section positioned on the side opposite to the cavity which extends towards the sealing portion of the gate mechanism (12 and 10). With this arrangement, the molten metal in passage (8) fills the ring-shaped groove (10e) and enters the small clearance which exists in the sealing portion of the gate mechanism. The molten metal solidifies both within the ring-shaped groove (10) and this small clearance formed in the sealing portion. The resulting solidified metal piece has generally a ring shape that can be readily peeled off from the gate mechanism (12 and 10) following die release.

    • A toner cartridge is detachably attached to an image forming apparatus and supplies toner to the image forming apparatus. The locking mechanism is positioned either at a locking position or at a non-locking position. Shortly after the toner cartridge has been attached to the image forming apparatus, the locking mechanism is at a non-locking position. When a user operates a driving member of the toner cartridge after the toner cartridge has been attached to the image forming apparatus, the operating lever engages the locking mechanism to cause the locking mechanism to move to a locking position. When the locking mechanism is at the locking position, the locking mechanism limits the driving member to move relative to the engagement portion, so that the toner cartridge is not allowed to be detached from the image forming apparatus.
    • 调色剂盒可拆卸地附接到图像形成装置,并将调色剂供应到图像形成装置。 锁定机构位于锁定位置或非锁定位置。 在将墨粉盒安装到图像形成装置之后不久,锁定机构处于非锁定位置。 当用户在调色剂盒已经附接到图像形成装置之后操作调色剂盒的驱动构件时,操作杆接合锁定机构以使锁定机构移动到锁定位置。 当锁定机构处于锁定位置时,锁定机构限制驱动构件相对于接合部分移动,使得调色剂盒不允许与图像形成装置分离。

    • A developer cartridge includes a developer storing portion in which a developer is stored, a developer supplying portion for supplying the developer to a main body of an image forming unit, an opening-and-closing member that opens and closes the developer supplying portion, an operating member for operating the opening-and-closing member, and an engaging portion engagable with a to-be-engaged portion formed on the main body of the image forming unit. The opening-and-closing member takes one of an opening position where the opening-and-closing member opens the developer supplying portion and a closing position where the opening-and-closing member closes the developer supplying portion, when the engaging portion engages the to-be-engaged portion. The opening-and-closing member takes the closing position where the opening-and-closing member closes the developer supplying portion, when the engaging portion disengages from the to-be-engaged portion.

    • The technical problem of this invention is to establish a method of processing a synthetic resin tube, in which the shape of a part of the tube wall is changed to form easily an attractively hollowed and/or raised portion in a fairly wide area of the tube wall. The object of this invention is to provide a tubular container having excellent decorativeness, appearance, or functionality that has never been found before. A method of processing a synthetic resin tube comprises utilizing a mandrel having a mold portion, which has at least a shape selected from a hollowed shape, a raised shape, and a hollowed and raised shape formed in a part of outer surface of the mandrel, and which is also provided with small through-holes in this mold portion; inserting a bottomed cylindrical mandrel into a synthetic resin tube, while bringing the inner wall of the tube in contact with the mandrel; heating and softening the tube in the portion facing the mold portion; deaerating the tube via a central opening and the through-holes to mold the softened portion of the tube in a manner similar to vacuum molding; and forming in the tube wall at least one of the portions selected from a hollowed portion, a raised portion, and a hollowed and raised portion.
