摘要： PROBLEM TO BE SOLVED: To realize long time continuous operation by reducing a charging work for a battery. SOLUTION: A power generating device 22 is mounted on a running body moved by a linear motor. Rotation of a wheel 19 for supporting a weight is transmitted to a generator provided in the power generating device 22. A power is transmitted to a monitoring apparatus, such as a monitoring camera apparatus 8, from the power generating device 22 and a charge battery 12 is charged. This constitution remarkably reduces the number of times of a work to charge the battery at a charge station to decrease working efficiency and in turn, remarkably increases a continuous working time.

摘要： PROBLEM TO BE SOLVED: To enable restart by intermittently providing stator-side coil modules and moving element-side magnet modules respectively, and arranging them so that at least one of the magnet modules always faces opposite to a coil module. SOLUTION: For example, magnet modules 10 and coil modules 21 are provided intermittently respectively. Constitution is so made, that one or both of two, front and rear, driving gears provided on a running substance 5 always faces opposite to some coil module 21 provided on a guide rail intermittently. Furthermore, a magnet detecting sensor 22 for sensing the relative positional relation between a magnet module 10 and a coil module 21, a change-over means and a circuit for controlling current flow to each coil module 21 are provided. Consequently, an appropriate current to flow into each coil 2 successively can be generated, and to have thrust generated always in one direction. Accordingly, it becomes possible to perform restart, even after the running substance 5 stopped once.

摘要： PURPOSE:To accurately obtain an image without generating halation, by picking up the image of an object to be measured by a TC camera through an LCD element and controlling the light permeability of the LCD element corresponding to the level of image data. CONSTITUTION:An arc 21a is projected to a base material 22 from a welding torch 21 to generate a molten basin 22a. The images of the arc 21a and the molten basin 22a are taken in by the LCD element 12 and TV camera 11 of an image input means to be converted to image signals which are, in turn, sent to an image analytical part 23. At this time, a light permeability control means 15 is provided in order to control image input means 12, 11 and said image signals are converted to a gradation differ ence level corresponding to the level of image data and the light permeability of the LCD element 12 is controlled so as to be contrary to the magnitude of the grada tion difference level and the light permeability of a part having strong luminous intensi ty is lowered to prevent the generation of halation on the images of the image analyti cal part 23. Further, output is issued from the analytical part 23 to control a welding power source controller 24 and a welding torch controller 25. Therefor, an image can be accurately obtained without generating halation and welding can be performed suitably.

摘要： PURPOSE:To enable an object to be measured in a short time and with a high accuracy by conducting an enlarged image formation with a second optical sensor on part of the object imaged by a first optical sensor and using the output information of both the sensors. CONSTITUTION:When the length between the points A and B on an object 21 is measured, first a first image sensor obtains image information and displays (4a) it on a first display. Then, in accordance with the movement of a window 5a displaced by window control means, driving means displaces a second image sensor to put the point A into a measuring field of view. At this time, a second display displays a part of the object 21 ncluding the point A on a display screen 9a. Then, measuring means detects the position of the point A on the screen 9a on the basis of second image information and, further, detects the position of the point A on the display screen 4a on the basis of the position of the second image sensor on the screen 4a, last-said position being detected by position detecting means. The position of the point A is detected as X-Y rectangular coordinate values having an origin at the upper left corner of the screen 4a. The point B is detected in the same manner and the measuring means measures the length between the points A and B.

摘要： PURPOSE:To achieve a quick measurement of roundness with ease by bringing a displacement sensor into contact with the inner surface of tube to be measured after it is so arranged on a pipe as to be displaceable with a displacement gauge horizontally incorporated in the tube. CONSTITUTION:A pipe 1 is retained horizontally at the axial position of a tube 21 to be measured and a mobile ring 4 is moved a fixed tube 9 along the pipe 1 and fixed. With the rising of arms 7 and 7', a mobile core 12 of each displacement sensor 8 gets into contact with the inner surface of the tube 21 being measured and moves in the diametrical direction of the pipe 1 according to the displacement of thereof 21. An electrical signal V0 corresponding to the movement d of the mobile ring 4 is output from a displacement gauge 2 while signals V1-V6 corresponding to a distance r are output from each displacement sensor 8. They are input to an arithmetic device 25 via an amplifier 22, an ADC23 and a switch 24. The inner radius R of the tube 21 being measured is computed with the arithmetic device 25 and indicated 26. This enables a simple and easy measurement of the roundness of the tube.

摘要： PURPOSE:To make possible scanning at minute angles and with good accuracy by using a wedge-form rotating prism of a small vertex angle. CONSTITUTION:A prism 19 made of wedge-form transparent glass or plastic of a small vertex angle alpha is mounted to the revolving shaft 21 of a rotating device 20 such as rotary solenoid or motor and is supported by a supporting ram 25 in the state where it is opposed to a laser oscillator 22. Then, when the laser beam oscillated from the laser oscillator 22 enters the prism 19 through a collimator 23 and the prism 19 is reciprocated at a fixed angle, then the laser beam is scanned according to the rotating angle thereof and the minute angles are scanned with high accuracy because the relation between the rotating angle of the prism 19 and the swing angle of the laser beam associates to the vertex angle alpha of the prism 19.

摘要： PROBLEM TO BE SOLVED: To control a propulsion direction precisely depending upon various soil properties irrespective of the skill of an operator. SOLUTION: Past execution data for each propulsion length in the same soil properties as those of an execution site are sequentially changed for corrective values including point positions and excavation correction directions of a drill head 7 in an actual excavation of the drill head 7. The changed execution data are used to provide expression using a statistical model and prepare a linear prediction expression, on the basis of which a plurality of excavation processes are analyzed for a plurality of subsequent sections from the latest point position of the drill head 7. An optimum excavation process is selected from the plurality of excavation processes.

摘要： PROBLEM TO BE SOLVED: To separate and align steel bars by arranging magnets with the same poles thereof located in the aligning direction of steel bars, laying a skid between the magnet and the steel bar, and regulating the travel of the steel bar in the aligning direction by a side stopper. SOLUTION: A deformed steel bar 1 is transported by a roller 2, and when the end part thereof reaches below an electromagnet 3, the roller 2 is stopped. An electric current is applied to the electromagnet 3 to generate a magnetic field. An electric current is let flow through a coil 7, thereby forming the same magnetic poles in the aligning direction of the deformed steel bar 1. A magnetic flux 9 generated from the N-pole of the electromagnet 3 returns to the S-pole through the deformed steel bar 1. Attractive force for coming into contact with and sucking to the upper electromagnet 3 and repulsive force for mutual repelling are applied to the deformed steel bar 1. Though the deformed steel bar 1 is lifted up by the attractive force applied in the direction of the electromagnet 3, it comes into contact with a skid 5 installed on the upper side to receive the reaction force, so that it will not brought into contact with or attracted to the electromagnet 3 itself. The deformed steel bar 1 is subjected to reaction force from a side stopper 4 to become stationary.
