摘要： A load control device for a working tool of a construction vehicle in which a signal detected by a speed detector or a traction force detector is fed back to produce a deviation signal between said signal and a desired signal. A memory unit has stored a desired value of speed or traction force for each acceleration and outputs the desired signal corresponding to an acceleration signal from an acceleration detector. The working tool is moved up or down according to the deviation signal and, through the feedback mechanism, the load applied to the working tool is automatically controlled so as to enable the construction vehicle to work at maximum work efficiency without operator's efforts.

摘要： Interconnect of communication between mobile objects by another mobile object is enabled. Station A transmits its own identifier to another mobile station on a broadcast basis. Out of other mobile stations, for instance, Station B receives the identifier of Station A, and returns a response including its own identifier. Station A notifies Station B of identifiers of nodes with which it can communicate. Station B notifies Station A of identifiers of nodes with which it can communicate. This sequence of processing enables information on nodes with which either station can communicate to be exchanged between Stations A and B, and a communication path to nodes to be found between Station B (station A) and another node via Station A (station B).

摘要： A device for controlling the height of a blade of a tracked vehicle includes a blade height position detector, a blade height controller for raising and lowering the blade, and a device for setting an initial height of the blade. When the transmission of the vehicle is shifted from the reverse to the forward position, the height of the blade is lowered to the target value. A switch selects between the target value set by the initial height setting device and a manually selected height depending whether or not the switching device selects the automatic operation or manual operation of the blade height controller.

摘要： This invention aims to improve the operability in a hydraulic drive machine. According to a load Pp on work machine actuators 3 and 4, a differential pressure of a discharge pressure Pp of a hydraulic pump and a load pressure PLS is varied. Further, the differential pressure is varied so that the differential pressure between the discharge pressure Pp of the hydraulic pump 2 and the load pressure PLS decreases as the load Pp on the work machine actuators 3 and 4 increases and a rotational speed .epsilon.E of an engine decreases. Furthermore, the rotational speed .epsilon.E of the engine 1, discharge pressure Pp of the hydraulic pump 2, the operation amounts S1 and S2 of the various operation levers are detected, respectively, the absorbing torque of the hydraulic pump 2 is set based on the detected rotational speed .epsilon.E and a target rotational speed .epsilon.ET, and the differential pressure between the discharge pressure Pp of the hydraulic pump 2 and the load pressure PLS is varied based on the detected values and the torque set value. By varying the differential pressure, it is possible to realize an optimal lever operability suitable for the current working conditions, and thus possible to remarkably improve the work efficiency.

摘要： A fuel management system detects theft of fuel from the fuel tank (81) of a working machine (1) or insertion of foreign matter into the fuel tank, and issues an alarm. The total operating hours of the working machine (1) and the actual volume and weight of the contents of the fuel tank (81) are measured immediately after the start and stop of the working machine (1), and transmitted to a server (10) which calculates the fuel consumption amount from the total operating hours, calculates the volume and weight of the fuel assumed to remain in the fuel tank (81) from the fuel consumption amount, and compares the calculated volume and weight with the actual volume and weight. If a large difference is detected in the volume or weight, an alarm is transmitted to a user terminal (20) and to the working machine.
