HYDRAULIC DRIVING UNIT FOR WORKING MACHINE, AND METHOD OF HYDRAULIC DRIVE

A fuel injection control device (an electronic governor and a controller) for an engine is capable of controlling the governor region to an isochronous characteristic. A working machine controller receives a delivery pressure signal and controls a regulator in such a manner that when the delivery pressure of a hydraulic pump exceeds a predetermined pressure, the displacement volume of the hydraulic pump does not exceed. A system enabling the dissemination of location data between user terminals and to and from network resources, and the utilization of the location data in a manner convenient to users. User terminals, such as cellular telephones, personal digital assistants (PDAs), personal computers, and other interactive devices, may be location-enabled or conventional user terminals capable of transmitting service request data to network resources. In the case of location-enabled terminals, the terminal may store a plurality of items of location data, including spatial coordinate data, for dissemination to other user terminals and/or for transmission to network resources. The items of location data may be derived from systems for sensing the location of the mobile terminal, including satellite base positioning systems such as the global positioning system (GPS) or network-based or assisted positioning systems. Other sources of location data include other user terminals, network resources or manual provisioning of location data by the user at the terminal. In an alternative embodiment, user-selected location data is stored in a network side store for use by the user in relation to a range of remote processes, and is made accessible to a range of other network resources or user. Items from the network-side store may be transmitted to others for use in relation to service requests and other processes.
