Abstract: In an image processing apparatus for performing a specified processing on image data read by an image reading apparatus, there is provided a technique to realize an improvement in efficiency of image processing.

Abstract: An image forming apparatus includes: an image data processing unit that extracts one image area for each page from bitmap images for a continuous even number of pages of an identical sheet size and creates a combined image obtained by combining these image areas; and a print processing unit that prints the combined image on one print sheet or a size same as the sheet size.

Abstract: An image forming apparatus according to the present invention is capable of executing printing processes for color images and monochromatic images and comprises a printer section capable of executing processes for color printing and monochromatic printing and a printing task management section for receiving a plurality of printing jobs including color printing jobs and monochromatic printing jobs as input, computationally determining the processing time required for each of the printing processes on the basis of the information indicating color printing or monochromatic printing and the information indicating the number of copies to be printed and outputting the data of the printing jobs of short processing time separately for monochromatic printing and color printing with priority to the printer section.

Abstract: There is disclosed an image forming apparatus, a program for printing with marks added, and a method for printing with marks added, which facilitate adding of marks to print data and reediting thereof. The image forming apparatus performs printing of data constituted by print data added with marks, and comprises: a print data storage section that stores print data; a marking data storage section that stores, as marking data, a character attribute indicative of a preset expression method such as character decoration; and a marking-printing section that prints a result of applying the character attribute to the print data.

Abstract: An embodiment according to the present invention is an image data processing system comprising a controller apparatus on a client side and an image forming apparatus of on a server side which are connected through a PCI bus in order to exchange information. When reading or writing file data stored in a storage device of the image forming apparatus, the controller apparatus accesses the file data through a memory space mapped to the PCI bus space on the target apparatus and by the use of the bus master facility, so that the software on the client side and the software on the server side can cooperate by using the file systems implemented in the both sides, and therefore the processing speed is increased.

Abstract: At the time of start of a reboot operation or a boot operation of an image forming apparatus, a system processing section confirms whether a configuration of an option processing section has changed, and whether data in storage devices in processing sections has changed. If the image forming apparatus fails to normally operate due to a combination of changed data, the system processing section overwrites data in the storage devices in the respective processing sections, with use of data stored in an external storage device, thereby realizing a latest, optimal combination of data.

Abstract: An information storage medium apparatus is provided which comprises one or two reproduction-only optical disc(s) incorporated in a cartridge. The cartridge can be applied to a conventional information recording and reproducing apparatus without any additional operation.

Abstract: In a method for manufacturing a shadow mask, the both surfaces of a metal sheet, except those regions in which small and large openings are to be formed, are coated with resist films. The upper surface of the metal sheet is further coated with an organic synthetic film. An etching solution is sprayed on the lower surface of the metal sheet, kept in a substantially horizontal position, to etch the region corresponding to the small opening, thereby forming small recesses. Thereafter, the resist film on the lower surface is removed. Then, the metal sheet is turned over, so the surface of the metal sheet with the small recesses therein faces up, and an etching-resistant layer is formed on the surface of the metal sheet which faces up. Then, the regions corresponding to the large openings on the surface of the metal sheet which faces down is etched, to form large recesses, while keeping the metal sheet substantially horizontal, until the large recesses are reached to the resistant layer.

Abstract: A color cathode picture tube including an envelope having a fluorescent screen therein, a shadow mask assembly having a shadow mask and a mask frame for holding the shadow mask at its peripheral edge, and a shadow mask supporting member for supporting the shadow mask assembly inside the envelope. The shadow mask supporting member comprises a first metal strip having a thermal expansion coefficient substantially equal to that of the mask frame, a second metal strip joined to the first metal strip at one side thereof so that their respective faces may form a continuous face, this second strip having a thermal expansion coefficient higher than that of the first strip, and a third metal strip joined to the first metal strip at the other side thereof so that their respective faces may form a continuous face, the third strip having a thermal expansion coefficient lower than that of the first metal strip.

Abstract: A method for etching an Fe-Ni alloy by reacting the Fe-Ni alloy with an etching solution which contains ferric chloride, has the step of adding Cl.sub.2 and H.sub.2 O in a reaction system of the etching solution and the Fe-Ni alloy, thereby producing ferric chloride, and thus, preventing degradation of the etching capability of the etching solution.

Abstract: A method for manufacturing a shadow mask by spraying an Fe-Ni alloy sheet with a ferric chloride solution to form apertures for passing an electron beam the ferric chloride solution is controlled to have 0.30.+-.0.20% by weight of free hydrochloric acid within a ferric chloride solution temperature range between 40.degree. C. and 70.degree. C., to have a total amount of Fe.sup.++ ions and Ni.sup.++ ions of not more than 15% by weight, and to have a specific gravity which falls within a region bounded between a curve plotted according to a relation 1.461-(4.63.times.10.sup.-4 T)-(1.96.times.10.sup.-6 .times.T.sup.2) (where T is a ferric chloride solution temperature) and a curve plotted according to a relation 1.552+(7.79.times.10.sup.-5 .times.T)-(1.18.times.10.sup.-5 .times.T.sup.2).
