摘要:
The invention reduces waste of flow volume of pressurized oil discharged from a hydraulic pump when the rotational speed of a cooling fan is increased to the target rotational speed. The target rotational speed of the cooling fan is set at a target rotational speed setting portion. An acceleration pattern for increasing the cooling fan to the target rotational speed is set at an acceleration pattern setting portion based on the rotational speed of the cooling fan, the target rotational speed set at the target rotational speed setting portion, and magnitude of force due to inertia of the cooling fan and the hydraulic motor. The rotational speed command value calculation portion controls the pressurized oil to be supplied to the hydraulic motor at a flow rate required. Thus, it is possible to reduce wasted relief flow volume.

A hydraulic excavator includes: an oil-pressure cut valve for suspending pressure oil supply to a PPC valve; a lock switch for operating the oil-pressure cut valve; and a control device for controlling a switching of the oil-pressure cut valve. The control device includes: a lock-state determining unit that determines a lock state of working equipment by considering the status of the lock switch; a traveling-state determining unit that determines a traveling state of the hydraulic excavator; an alert-issuing controlling unit that issues an alert urging locking of the working equipment; and a relay control unit that actuates the oil-pressure cut valve to suspend the flow of pressure oil. The alert-issuing controlling unit issues the alert and the relay control unit actuates the oil pressure cut valve when the hydraulic excavator is determined to be traveling and the working equipment is determined not to be in the lock state.

An aligning method suitably usable in a semiconductor device manufacturing exposure apparatus of step-and-repeat type, for sequentially positioning regions on a wafer to an exposure position. In one preferred form, the marks provided on selected regions of the wafer are detected to obtain corresponding mark signals and then respective positional data related to the positions or positional errors of the selected regions are measured, on the basis of the mark signals. Then, the reliability of each measured positional data of a corresponding selected region is detected, on the basis of the state of a corresponding mark signal or the state of that measured positional data and by using fuzzy reasoning, for example. Corrected positional data related to the disposition of all the regions on the wafer is then prepared by using the measured positional data of the selected regions, wherein, for preparation of the corrected positional data, each measured positional data is weighted in accordance with the detected reliability thereof such that measured positional data having higher reliability is more influential to determine of the corrected positional data. For sequential positioning of the regions on the wafer to the exposure position, the wafer movement is controlled on the basis of the prepared corrected positional data, whereby high-precision alignment of each region is assured.
