摘要： The problem of ensuring safety and work efficiency for the actions of a control target is addressed in an environment in which different types of control systems coexist. A safety control server controls the actions of respective control targets in differing systems and includes an action adjustment unit that, for each control target of differing control systems, outputs to a control target an action adjustment instruction for adjusting the action of that control target when a contention occurs in which the action of that control target deviates from an assumed control result. An action plan adjustment unit, when the adjustment of the action satisfies a prescribed condition, adjusts an action plan indicating an action rule for achieving a function and avoiding a contention in a control target; and a safety rule adjustment unit adjusts a safety rule indicating an action rule for avoiding a contention in the control target.

摘要： Provided is a remote control system which controls a work machine from a remote place in order to improve safety and workability and to reduce fatigue of an operator. In the remote control system which controls the work machine from a remote place, a seat where the operator sits is driven to be inclined in conjunction with the machine, so that inclination information of the machine at the time of traveling is provided to the operator to be sensible and the safety and the workability are improved. On the other hand, a large inclined vibration caused by the work of the machine is not transferred to the operator since an inclination amount of the seat is kept when the machine is not traveling, so that the fatigue of the operator is reduced.

摘要： A high-pressure fuel pump includes a pressurizing chamber for pressurizing fuel, an outlet valve for discharging the fuel pressurized in the pressurizing chamber to an outlet passage, a relief passage for connecting the outlet passage located downstream of the outlet valve and the pressurizing chamber with each other while bypassing the outlet valve. A relief valve device is provided in the relief passage and adapted to open when an internal pressure of the outlet passage becomes higher than that of the pressurizing chamber, thereby providing communication between the outlet passage and the pressurizing chamber. The relief valve includes a relief spring mechanism for pressing a relief valve to a relief valve seat. At least the relief spring mechanism among members of the relief valve device is provided outside the pressurizing chamber in the pump body.

摘要： In testing a component-set whole process which includes a plurality of components and in which the order of execution of the plurality of components is defined, a computer system exports, to a storage resource, an input package for at least one component to be executed. Each of the plurality of components is a module of a significant process as a set of one or more processing steps and independent of any other components. Each input package includes an input value of a component that corresponds to the input package. The computer system imports an exported input package of a component to be debugged into the component to be debugged in order to execute the component to be debugged, without executing a component the order of which precedes the order N (where N is a natural number) of the component to be debugged.
