Abstract: An agent program 141 stores a log file in a storage device 150. By controlling an access to the storage device 150 according to volume management information 153, the storage device 150 prevents the log file from being updated. A manager program 142 communicates with the agent program 141 to collect the log file. On the completion of the log collection, the manager program 142 adds a signature to a log deletion message by use of a security chip 105. Then, the agent program 141 verifies the signature by use of a security chip 104 to judge that a log deletion request is valid. After that, the volume management information 153 which has been used to protect the log file is rewritten so that the protection is removed.

Abstract: A system, such as hardware or software system having a number of modules, is simulated using multi-tasking computer code. Simulation computer code launches tasks simulating system execution, where each task corresponds to a module. Each task requests a processing delay to a common scheduler. Upon the common scheduler receiving a processing delay request, the common scheduler instructs a scheduling method processor to update a task-remaining time for at least one task. The scheduling method processor updates the task-remaining time for at least one task based at least on a scheduling approach. The common scheduler sends a wait request to a preexisting simulation system to delay a module that corresponds to the task by a length of time, based on the task-remaining time for the task and the scheduling approach. The preexisting simulation system delays the module that corresponds to the task by the length of time of the wait request.

Abstract: An impeller for a fluid transmitting device includes a hub and a bowl-shaped shell connected to an outer peripheral portion of the hub via an annular weld seam. An inner peripheral surface of the shell is fitted to an outer peripheral surface of the hub, and the weld seam is formed therebetween by laser welding over an entire length of fitting depth. Thus, it is possible to form the annular weld seam between the hub and the shell with a relatively small amount of heat input, and to precisely perform a visual inspection as to whether the weld seam is good or not without any skill.
