20110216351 | IMAGE FORMING APPARATUS AND COMPUTER READABLE MEDIUM STORING PROGRAM - An image forming apparatus includes: a print command receiving unit that receives print command information indicating a print command; an authentication determination unit that determines whether or not the print command information received by the print command receiving unit includes authentication requirement information indicating that authentication is required upon print processing based on the print command; a determination unit that, when the authentication determination unit has determined that the print command information includes the authentication requirement information, determines whether or not an originator of the print command information and a user who performs the print processing based on the print command information are different; and a notification unit that, when the determination unit has determined that the originator of the print command information and the user who performs the print processing are different, notifies the user who performs the print processing of presence of the print command information. | 09-08-2011 |
20110228309 | PRINT JOB INFORMATION MANAGING DEVICE, PRINT JOB INFORMATION MANAGING METHOD, AND RECORDING MEDIUM - A print job information managing device of the present invention has: an authentication request instruction adding section that adds, to a print job, an authentication request instruction that expresses whether or not authentication is needed at a time of printing; a transmitting section that transmits the print job to a printer; and a notification section that, when the authentication request instruction has been added to the print job transmitted by the transmitting section, notifies a printing recipient that the print job has been transmitted. | 09-22-2011 |
20120250066 | IMAGE FORMING SYSTEM, INFORMATION MANAGEMENT SERVER, AND COMPUTER READABLE MEDIUM STORING PROGRAM - An image forming system includes an information management unit, a determining unit, and at least one image forming unit. The information management unit stores and manages print information. The determining unit determines whether or not execution of a printing process regarding the print information is allowed. Each image forming unit prints and outputs print information acquired from the information management unit on a recording medium in accordance with a determination result of the determining unit. The determining unit includes a first authenticating unit and a second authenticating unit. The first authenticating unit performs authentication to determine whether or not execution of processing before printing and outputting the print information on a recording medium is allowed. The second authenticating unit performs authentication after completion of the authentication performed by the first authenticating unit to determine whether or not printing and output of the print information on the recording medium is allowed. | 10-04-2012 |
20120250067 | IMAGE FORMING SYSTEM AND COMPUTER READABLE MEDIUM STORING PROGRAM - An image forming system includes an information management unit, at least one image forming unit, an authenticating unit, a determining unit, an adding unit, a notifying unit, and a controller. The information management unit stores and manages print information. Each image forming unit forms an image on a recording medium in accordance with the print information. The authenticating unit authenticates a recipient of an output result of the image forming unit. The determining unit determines whether or not the print information requires authentication. The adding unit adds authentication information about the recipient to the print information when the print information requires authentication. The notifying unit notifies the recipient of information regarding the print information with the authentication information added. The controller controls the information management unit to transmit the print information to the image forming unit to form an image when the recipient has been successfully authenticated. | 10-04-2012 |

20100180279 | FIELD CONTROL DEVICE AND FIELD CONTROL METHOD - A field control device is provided. The field control device includes: a task executing unit configured to selectively and sequentially execute a control task relating to a field control and other tasks in a same control period; and a priority switching unit configured to switch a relative priority of the control task relative to the other tasks in the control period, wherein the priority is a priority of an execution sequence of tasks in the task executing unit. The priority switching unit is configured to: i) set the priority higher than a certain priority, before the control task is started; and ii) set the priority lower than the certain priority, after the control task is ended. | 07-15-2010 |
20100198363 | DISTRIBUTED CONTROL SYSTEM - There is provided a distributed control system including a plurality of field controllers which are connected through a control network. Each of the field controllers includes: a control clock that defines a control timing of the field controller; and an adjustment unit that adjusts a control time of the control clock depending on a network time obtained through the control network. | 08-05-2010 |
20100198991 | DUPLEXED FIELD CONTROLLER - There is provided a duplexed field controller. The duplexed field controller includes: first and second control units between which a control authority is switchable; a first application clock that is updated based on a reference clock so as to define a timing of an application operation of the first control unit; a second application clock that is updated based on the reference clock so as to define a timing of an application operation of the second control unit; and an update control unit that bypasses the first update of the second application clock after switching of the control authority, if the first application clock is ahead of the second application clock when the control authority is switched from the first control unit to the second control unit. | 08-05-2010 |
20100199003 | FIELD CONTROL SYSTEM - The field control system includes: a field device; a field controller which is connected to a control network and which executes a computation processing for controlling the field device according to a given control cycle while executing a data communication between the field controller and the field device, the field controller including a communication unit configured to execute the data communication with the field device, and a control computation unit configured to execute the computation processing independently from the communication unit; and an operation monitor which is connected to the control network and which operates and monitors the field device, the operation monitor including a network clock which provides a common network time to the control network. The control computation unit and the communication unit execute the computation processing and the data communication in synchronism with each other in accordance with a timer clock based on the network time. | 08-05-2010 |
