Patent number: 7827287Abstract: A system and method for identifying a communication connection with an interim identifier prior to recognition of an original or previous identifier received via the connection. A first server or server process receives a service request (e.g., for an application, a web page or other data), and associates an original identifier with the request via one or more log entries. The request is forwarded to a second server or server process for additional or final processing. The second server associates an interim identifier with the communication connection established to receive the service request from the first server. The interim identifier is logged with one or more events associated with establishment of the connection and/or receipt and processing of the service request. When the original identifier is read and recognized, the interim identifier is bridged or mapped to the original identifier via a distinct log entry.Type: GrantFiled: February 14, 2005Date of Patent: November 2, 2010Assignee: Oracle International CorporationInventors: Hideaki Hayashi, Rajesh Nanda

Publication number: 20090317154Abstract: Fixing belt is brought into pressure-contact with the surface of fixing roller such that fixing belt rotates according to rotation of fixing roller, thereby forming, between fixing belt and fixing roller, fixing nip portion through which recording sheets pass. A pressing area of an opposing surface of pressing member contacting the surface of fixing roller via fixing belt is smaller in each end portion of the opposing surface in the axis direction of fixing roller than in a central portion of the opposing surface in the axis direction of fixing roller. This makes speed of conveying recording sheets faster in each edge portion in the width direction perpendicular to a recording sheet conveyance direction than in a central portion in the width direction. Thus, creases of recording sheets can be prevented while a recording sheet passes through fixing nip portion between fixing roller and fixing belt mutually brought into pressure-contact.Type: ApplicationFiled: June 10, 2009Publication date: December 24, 2009Applicant: Konica Minolta Business Technologies, Inc.Inventors: Kazunori NISHINOUE, Norikazu Okabe, Hideaki Hayashi, Taizou Oonishi, Naoki Yamamoto
