摘要:
An image forming apparatus for forming an image on a recording medium, includes a frame of the image forming apparatus, and a toner container mounting for removably mounting a toner container for containing toner removed from an image bearing member provided in the frame. The toner container mounting is removably mounted to the frame. An opening/closing member openable with respect to the frame is adapted to be opened and closed to dismount and mount the toner container with respect to the frame, and a regulating devise for regulating the closing of the opening/closing member when the toner container is not mounted to the frame.

The execution of an instruction for one of co-processors is subrogated by information processing function implemented in the host-processor. When a co-processor identification code involved in the instruction for the co-processor agrees with a host-processor internal processing identification code set in the host-processor, the instruction decoder of the host-processor starts the information subrogating processing function. Thus, protocol control for communication from the host-processor to co-processors can be omitted so that a high-speed data processing becomes possible.

An automatic software configuring system includes a database storage section for storing therein a plurality of soft components. In the event that soft components are extracted from the database storage section and are combined together to thereby generate a file, a comment indicative of a storage location in the database storage section for storing a respective soft component extracted from the database storage section is added to the respective soft component. The automatic software configuring system further includes a device for identifying the respective soft component combined into the file and a storage location of the respective soft component by reading the comment; a device for identifying a comparison-target soft component stored in the database storage section; a device for identifying a soft component having a different content; and a device for replacing specified soft component in the database storage section with the soft component combined into the file.

A developing device includes a developing container for accommodating a developer; a developer carrying member, disposed in an opening of the developing container, for carrying a developer; a developer charging member for being contacted to the developer on the developer carrying member and supplied with a voltage of the same polarity as the developer and not less than a discharge start voltage.
摘要:
A developing apparatus having a developer containing portion including an opening portion for supplying a developer to a developer bearing member, a sheet member for unsealably sealing the opening portion, and a partition wall for partitioning a space of a developer containing portion into a first space and a second space more remote from the developer bearing member than the first space. The partition wall has an angle of 30 degrees or less with respect to a surface on which the sheet member is supported, and has an angle of 40 degrees or more with respect to a horizontal plane when the developing apparatus is attached to a main body of an image forming apparatus. A first carrying and a second carrying member are disposed in the first space and the second space respectively to carry the developer to the opening portion. Before the sheet member is unsealed, the second carrying member is stopped so that a tip end portion of the second carrying member in a rotation radius direction thereof comes close to a tip end portion of the partition wall, and the first carrying member is stopped so that a rotation phase deviates from a stop position of the second carrying member on an upstream side of the rotating direction by an angle of 75 degrees and 105 degrees.
摘要:
A microprocessor having a buffer or memory capable of holding a plurality of instructions in advance of execution also functions to insert a special bus cycle amongst the instructions for outputting the internal information of the microprocessor to the outside in a predetermined operation mode at the time of each execution. The information inside of the microprocessor, which is to be outputted to the outside in the special bus cycle, is identified by the address of the executed instruction in a memory space, an instruction code or the code for identifying said executed instruction in the instruction group prefetched. In an emulation of the system using the instruction prefetch type microprocessor, as described above, what instruction has been executed can be easily known from the outside to effect an accurate emulation analysis and to facilitate the analysis of trace data thereby to improve debugging efficiency.
摘要:
A polycarbonate resin composition comprising a blend of (A) 1 to 90% by weight of a polycarbonate resin derived from 2,2-bis(4-hydroxyphenyl)propane and (B) 10 to 99% by weight of a polycarbonate resin derived from 1,1-bis(4-hydroxyphenyl)ethane, the amounts of (A) and (B) being based on the total weight of (A) and (B). The composition has improved impact strength and melt flowability while retaining the excellent transparency and heat deformation resistance of the polycarbonate resin (A).
