The communication apparatus includes a determination unit configured to determine whether priority is to be given to the apparatus function over the communication control function in the case that an instruction to implement the apparatus function is received while the apparatus is implementing the communication control function and operating as the control apparatus, and a control unit configured to control operation of the apparatus such that priority is given to the apparatus function over the communication control function in a case that the determination unit determines that priority is to be given to the apparatus function over the communication control function.

Abstract: A network address management unit (210) allocates, to the first edge node, a first network address (500) on which a physical configuration of a first edge node (100a) is reflected. The network address management unit, when a second edge node (100b) is coupled to the first edge node, allocates, to the first edge node, a second network address (510) on which the physical configuration of the first edge node is reflected with respect to the second edge node. When the first edge node receives a packet that designates the first or second network address as a destination network address, the first edge node, based on the destination network address designated by the received packet, determines whether the received packet is transferred to the second edge node and discriminates a transfer destination path in the first edge node.

Abstract: A hydraulic working machine has an assist electric motor connected to an engine and a hydraulic pump. The emissions of air pollutants in the exhaust gas from the engine are minimized regardless of fluctuations in the load torque of the hydraulic pump. A specific revolution speed suitable for reducing the emissions of air pollutants is stored, and an engine is controlled using the specific revolution speed as a target revolution speed. The absorption torque of a hydraulic pump is subjected to high-pass filtering whereby a high-frequency component devoid of a trend component is obtained. Target assist torque is computed from the high-frequency component, and the assist electric motor is subjected to power running/generation control accordingly. A specific output torque range suitable for reducing the emissions of air pollutants is stored, and the target assist torque is corrected so that the trend component does not exceed the specific output torque range.

Abstract: Operation management of equipment is made efficient by verifying a plurality of operation management manipulations on a plurality of equipment and optimizing a manipulation order before executing the manipulations. A status of equipment in a status table; a content of a manipulation in a manipulation table; a process time of the manipulation in a manipulation time prediction table; and a status required for the manipulation in the manipulation table are memorized on an operation model managing server. When a plurality of manipulations are input for a plurality of equipment by an operation manager via an operation managing server, correctness of the manipulations is verified and a manipulation order is decided on an operation verifying server based on the various types of memorized information. Also, a manipulation end time of each manipulation is notified to the operation manager via the operation managing server.

The autonomous distributed type file system includes a plurality of storage device units which are mutually connected through a second network and are connected to the first network. Each of the storage device unit includes a local storage and a local controller. The local controller includes a storage directory and a duplicated data maintaining unit. The duplicated data maintaining unit refers to the storage directory, and continuously keeps same contents of duplicated data items in a range without running out of storage capacity of an own node. When there is no free space in the storage capacity, duplicate writing of the data with the same contents is prevented.
