Patent number: 7006119Abstract: An image forming apparatus forms on a photoconductive body an evaluation chart including first patterns and second patterns. In the first pattern, with respect to a row of dots formed in a main scan direction by a predetermined light beam, a row of dots formed by a next light beam is shifted in the main scan direction, and in the second pattern, with respect to the row of dots formed in the main scan direction by the predetermined light beam, the row of dots formed by the next light beam is shifted in the main scan direction but in a direction opposite to a shift direction of the first pattern. The evaluation chart includes a first pattern group which is formed by the first patterns which are repeated, and a second pattern group which is formed by the second patterns which are repeated.Type: GrantFiled: September 29, 2004Date of Patent: February 28, 2006Assignees: Ricoh Company, Ltd., Ricoh CorporationInventor: Toshihiro Takesue

Patent number: 6970952Abstract: A method and system for monitoring, controlling and diagnosing operation of a machine such as a business office machine including a facsimile machine, a copier, and a printer. When the speed of communication between the remote device and machine is not urgent, a connectionless mode of communication may be used. The form of connectionless communication is an electronic mail message transmitted over the Internet. However, when a condition needs urgent action, a direct connection is used for communication such as communication via a telephone or ISDN line. The information obtained from the machine is stored in one or more data bases within a company and information of the machine is shared between a service department, engineering and design department, manufacturing department, and marketing department. As communication over the Internet via electronic mail is not secure, the connectionless-mode messages transmitted using Internet electronic mail are encrypted.Type: GrantFiled: October 30, 1996Date of Patent: November 29, 2005Assignees: Ricoh Company, Ltd., Ricoh CorporationInventor: Tetsuro Motoyama

Patent number: 6873734Abstract: A compression and decompression system in which a reversible wavelet filter are used to generates coefficients from input data, such as image data. The reversible wavelet filter is an efficient transform implemented with integer arithmetic that has exact reconstruction. The present invention uses the reversible wavelet filter in a lossless system (or lossy system) in which an embedded codestream is generated from the coefficients produced by the filter. An entropy coder performs entropy coding on the embedded codestream to produce the compressed data stream.Type: GrantFiled: February 7, 2000Date of Patent: March 29, 2005Assignees: Ricoh Company LTD, Ricoh CorporationInventors: Ahmad Zandi, Edward L.

Patent number: 6874092Abstract: An approach for storing and maintaining data is disclosed. One or more sensors are provided for detecting unauthorized access to a first non-volatile storage. If unauthorized access to the first non-volatile storage is detected, then the data on the first non-volatile storage is deleted by overwriting the data on the first non-volatile storage with a predetermined value so that the data cannot be recovered. The first non-volatile storage is registered with a registration authority to provide authentication of the data maintained on the first non-volatile storage.Type: GrantFiled: September 4, 2001Date of Patent: March 29, 2005Assignees: Ricoh Corporation, Ricoh Company, Ltd.Inventors: Tetsuro Motoyama, Masuyoshi Yachida

Publication number: 20040215671Abstract: A system, method and computer program product for managing documents. The system includes an image forming apparatus configured to display interactive menus so as to allow an operator of the image forming apparatus to interact with a document manager. The display interactive menus are downloaded from the document manager to the image forming apparatus based on a request by the operator. The document manager is configured to search for application services providers (ASPs) over a network and based on operator inputs. The document manager can search documents within the ASPs, retrieve documents and URLs, store documents and data.

Patent number: 6802059Abstract: A method and apparatus for transforming character strings that are contained in a unit of code. A conversion mechanism performs a macro substitution by transforming hard coded strings into unique macro strings. The conversion mechanism is configured to receive a set of computer instructions that are contained in one or more files. The conversion mechanism parses the instructions to identify character strings included within the computer instructions, while copying the files to one or more output source code files. Upon identifying each string, the conversion mechanism generates a unique macro string as a substitute for the original string. The conversion mechanism then substitutes the unique macro string for the identified string in the source code of the computer program. The conversion mechanism also generates an entry in a macro list that associates the unique macro string with the identified string for use during compilation of the computer instructions.Type: GrantFiled: August 2, 1999Date of Patent: October 5, 2004Assignee: Ricoh CorporationInventors: Yevgeniya Lyapustina, Tetsuro Motoyama

Patent number: 6801331Abstract: A method and system which allows a remote monitoring and diagnostic computer or system to communicate using different communication protocols which are stored within a data base. After a communication is received, it is analyzed to determine if there is a protocol identifier. If the protocol identifier exists, a data base is searched to determine the format of the header of the communication. Once the format of the header is determined, the header of the received communication is read to determine the information contained therein. This information is utilized to determine the actual format of the data which follows. If the protocol identifier does not exist, the received communication is examined to determine if it is in a format which matches one of a plurality of previously defined format.Type: GrantFiled: July 1, 1998Date of Patent: October 5, 2004Assignees: Ricoh Company, Ltd., Ricoh CorporationInventor: Tetsuro Motoyama

Publication number: 20040080786Abstract: An automatic archiving system that makes document archiving largely transparent to the user. In one embodiment, documents scanned in or printed during the course of office equipment operation are automatically archived. For example, an office local area network (LAN) may interconnect a copier, a printer, a fax machine, and a document management workstation. Whenever, a document is copied, printed, or faxed, a document image is archived by the document management workstation without further user intervention. A single user command results in the document being copied and archived, printed and archived, or faxed and archived.Type: ApplicationFiled: June 2, 2003Publication date: April 29, 2004Applicants: Ricoh Company, LTD., Ricoh CorporationInventors: Jonathan J.

Publication number: 20040073403Abstract: A system is described for automatically invoking computational resources without intervention or request from a user of the system. The computational resources may operating by searching across a network, or may themselves be located across a network. In the system a query-free information retrieval system is described in which the exact technical documentation contained in existing user or other technical manuals is provided to a user investigating apparatus having a fault. The user enters symptoms based upon the user's analysis of the apparatus, and in response the system provides information concerning likely faults with the apparatus. As the symptoms are entered, the relative value of individual faults is determined and related to the symptoms they cause. The user can then select technical information relating to probable faults in the system.Type: ApplicationFiled: June 13, 2003Publication date: April 15, 2004Applicants: Ricoh Company Limited, Ricoh CorporationInventors: Peter Hart, Jamey Graham
