摘要： PURPOSE:To provide a virtual sound producing device for operation of a working machine with which it is practicable to grasp the working conditions certainly and perform proper operation even in case the place of works is not visible. CONSTITUTION:Operation signals of operational levers 11La-11Lc of a remote control device 10 are wirelessly transmitted to a control device 23 on the working machine side so that proportional solenoids 2a-21c of control valve are energized, and thereby the working machine is driven. The load on the working machine is sensed by a load sensing device 26 and transmitted wirelessly to a control device 13 in the remote control device 10, and a frequency converter 138F in the control device 13 emits a frequency signal in conformity to the load signal. This frequency signal is amplified by an amplifier 138A with a rate of amplification according to the maximum among the turning amounts of the operational levers, and the amplified signal is emitted from a speaker 17 as a virtual sound. The working condition can be grasped by listening to the virtual sound to enable proper operation of the working machine.

摘要： PURPOSE:To increase safety of a work through prevention of a fall accident by predicting the fall of a body based on detected values from respective sensors and an amount of change per time. CONSTITUTION:A future load state predicting means 6 predicts the state of a load exerted on each part of a body on and after a present point of time as reference to a data base 4 is made based on a load state at a point of time when reproduction is effected by a present load state reproduction state predicting means 5, detected values from sensors 1-3, and an amount of a change with a time. It is discriminated by a fall discriminating means 7 from a reproduced load state at a present point of time and by a fall discriminating means 8 from a predicted load state on and after a present point of time whether load distribution of a body ground touching part causes the fall of a body. A stop/avoidance operation signal output means 10 stops an actuator when it is discriminated that a fall occurs and/or transmits a signal, by means of which avoidance operation is effected so that a fall can be prevented, to a controller 9. An announcing means 11 announces it to an operator that a fall may take place.

摘要： PURPOSE:To detect a buried foreign object before it is brought into contact with a bucket during an automatic excavation. CONSTITUTION:The excavation depth (d) of a bucket 5 is determined from the measured value of an angle sensor 11. The depth (d) is compared with the target depth D, and the flow to a cylinder is adjusted for an automatic excavation. The vector of the excavation resistance is obtained from the detected values of load cells 18, 19. The presence of an abnormality of the obtained vector is judged in reference to a data base, and the presence of a foreign object is predicted. When the presence of the foreign object is predicted, the excavation is temporarily stopped, then the target excavation depth D is corrected, and an automatic excavation is restarted.

摘要： PURPOSE:To regulate a pre-load in an adequate value by providing an extension member for regulating pre-load to at least one side of a track rail or a sliding board. CONSTITUTION:At least on one side either a track rail 1 or a sliding board 3, an extension member 102 for regulating pro-load which can regulate the interval between opposing rolling element running grooves on which a rolling element is placed is provided, and by extending and contracting the extension member 102, the pre-load is regulated. That is, when a low friction in the running time and the like is required, the pre-load is reduced so as to move lightly, and when a set time in the positioning stopping time is required to reduce, the pre-load is increased so as to increase a damping property. Not only in the running or the stopping time, of course, but also when a variable load is applied in a running condition or the stopping condition, the pre-load is increased so as to increase the dynamic rigidity, and the displacement amplitude is reduced.

摘要： PURPOSE:To provide a machining device capable of detecting-recognizing the cutting state and shape accuracy during machining at real time to perform feedback to machining in an ultra-precision cutting field. CONSTITUTION:A lathe 2 for machining a sensitized drum base body 1, being a thin metallic cylinder member, is provided with a tool rest 3, and a force sensor 4 for detecting machining reaction during cutting is fitted to the tool rest 3. An output signal obtained from the force sensor 4 is amplified by a dynamic distortion gage 5 and changed into a digital signal by an A/D converter 6 so as to be taken into a computer 7. A memory and a disk device are connected as a storage means 8 to the computer 7. Plural mode pattern signals stored in the storage means 8 and classified according to the machined surface state at the time of cutting are compared with the output signal obtained from the force sensor 4 by a comparing means 9 to detect the state during cutting. The computer 7 prepares signals for controlling machining after detection and sends control signals to an NC device or a sequencer 10 for controlling the lathe 2 through a digital IO board RS232C interface or the like.
