Abstract: In a communication system wherein a device and a client communicate data with each other through a network, the device holds a root certificate including a public key in a pair of the public key and a private key and signed with the public key. When data is sent, a certificate creator creates a second certificate including the root certificate designated as a certificate authority at a higher level and signed with the root certificate, and the second certificate is sent to the client. In the client, the root certificate has been stored beforehand, and a verifier verifies the signature of the second certificate with the root certificate.

Abstract: The present invention provides a database system capable of dealing with dynamic changes in an event that vary continuously with time. A database system outputs a retrieval output from data in response to a user's retrieval request on the basis of a retrieval logic. The retrieval logic is allowed to evolve on the basis of a logical model. This logical model establishes a general relationship which leads results from conditions relating to a group of events that are dealt by a data group. Moreover, a database system optimizes a data structure on the basis of the logical model. The logical model can be transferred in a separated manner from the specific data contents of the data group. Therefore, the logical model can be exported to another database system of the same kind, and also imported from another data base system of the same kind.

Abstract: A data processing apparatus includes an input portion, an output portion, a plurality of compressing/expanding devices which compress data-to-be-outputted inputted from the input portion and expand compressed data-to-be-outputted, a file memory which stores the data-to-be-outputted compressed by some or all of the plurality of compressing/expanding devices, a data discrimination portion which discriminates whether the data-to-be-outputted inputted from the input portion is data including a small amount of information or a large amount of information, and a transfer controller. In cases where it is discriminated by the data discrimination portion that the data-to-be-outputted is data including a small amount of information, the transfer controller transfers the data-to-be-outputted to the output portion through the plurality of compressing/expanding devices operating in parallel.

Abstract: A computer program for a controlling apparatus intended to control an image forming apparatus, executes a procedure of confirming each program running on the controlling apparatus. The computer program executes procedure of judging a program, which is not included in a preset list of programs that can be run to control the image forming apparatus among programs whose running states have been confirmed, as an illegal program resulting from computer virus infection. The illegal program is automatically deleted or isolated.

Abstract: A technology for use in an e-mail transmission apparatus capable of preventing or discovering ‘impersonation’ in e-mail transmission efficiently, in which an e-mail is sent not only to a receiving address, but also to a sending address set by a sender.

Abstract: A printer (100) for printing based on a print job signal sent from a data processing device (200) registers print job signal sending sources and a message corresponding to each sending source in memory (111, 112). A controller (113) detects whether the sending source of a received print job signal is registered in memory. If the sending source is registered, a messaging unit (110, 111) outputs a corresponding message. Sending sources that are permitted to print can also be registered in memory (111, 112). In this case, the controller (113) detects whether the sending source of a received print job signal is registered in memory, and instructs the printer (110) to print only when the sending source is registered as permitted to print.

Abstract: The E-mail server of the invention receives E-mail addressed to a portable terminal unit, and transmits receipt notice E-mail prepared by removing the attachment file portion of the received E-mail to the portable terminal unit. On the other hand, the E-mail server acquires the location information of the portable terminal unit. The E-mail server selects a device among multiple printers and facsimile devices according to the acquired location information. The E-mail server transmits the data corresponding to the attachment file portion to the selected device.

Abstract: The present invention relates to a glass substrate of which the outer periphery portion is unprocessed. The present invention also relates to a manufacturing method for a glass substrate of which the outer periphery portion is unprocessed, characterized in that a first lapping process, a second lapping process, a polishing process and a washing process are carried out after a press molding process is carried out so as to compress glass between an upper mold and a lower mold without regulating the edge surface of the outer periphery portion of the glass and, then, a crystallization process or an annealing process is carried out.

Abstract: A computer readable recording medium bearing a printer driver program for controlling a print device, which is installed in a print job data processing apparatus constituting a printing system together with the printing device, the printer driver program comprising computer executable instructions of; receiving a print job data from an application program which has a print command; analyzing the received print job data from the application program to identify respective objects included in the page description language data; calculating a position where each object is arranged on a printable area designated depending on output paper size; and modifying the object to allow the object to be accommodated within the printable area, thereby accomplishing a correct print operation such that a print region designated by a user is accommodated to a predetermined output paper size without depending on a function of an application.

Abstract: Multiple user boxes are created beforehand in the hard disk drive of the MFP. The user specifies his own user box and saves image data therein. If the user extracts the image data from his user box and moves it to a folder on his own personal computer, the MFP 1 detects this action. When this user box is specified during a subsequent reading of image data, the storage destination for the image data is automatically deemed to be the folder on the personal computer to which the image data was previously moved.

Abstract: In case of transmitting a document file such as a PDF file to a printer without converting it into print data, a PC extracts from the document file to be printed information to be accessed when starting an analysis of the document file and transmits the information to the printer. The PC extracts a specified data from the document file and transmits it to the printer each time when the specified data is requested by the printer.

Abstract: When electronic mail with firmware attached is received at a data communication apparatus, determination is made whether it corresponds to firmware data of a write process allowable state. In the case of write process allowable data, the message is downloaded from a mail server to a printer controller. Then, derived firmware is transmitted to an image formation apparatus. A firmware rewrite permission is obtained. When the firmware attached to the message does not attain a write process allowable state, waiting is conducted for reception of write process allowable firmware with the data left in the mail server. As a result, a data communication apparatus is provided that can rewrite firmware appropriately independent of a transmitted and received order of divided firmware.

Abstract: The image forming apparatus receives image data based on multiple document images of various sizes and/or orientations. The apparatus identifies areas that are not yet assigned with document images on a single sheet of paper and identifies whether any document image can be laid out in an identified area. In another aspect of the apparatus, a maximum document image size is detected from multiple document images, and a scale factor is calculated to cause the detected maximum size match with the size of the entire area of the paper or an area obtained by dividing the paper into equal parts. In another aspect of the apparatus, a scaling factor is calculated for each document image to cause the size of the particular document match with the size of an area obtained by dividing the paper into equal parts.
