摘要： PURPOSE:To obtain an automatic operation-type stereo television set which can lighten the burden imposed on an operator by adjusting a zoom so that horizontal length of an object including target points displayed on a monitor display screen becomes always constant. CONSTITUTION:When an operation is set to an automatic mode, current positions of a horizontal swing motor 8 of a universal head 1 and a horizontal swing motor 9 of a slab manipulator are detected by potentiometers 10 and 11, and the position of the slab is made coincide with that of the universal head 1. When a target point is displayed on a picture processing monitor 5, it is set by a write pen 16, and detected trigger signals are transmitted to a write pen controller 17, which detects a target point on the monitor 5 and transmits its position to a microcomputer 18. The computer 18 operates horizontal/vertical swing angles of the universal head 1 in accordance with its automatic algorithm, and makes the universal head 1 swing so that a target point comes to the center of the screen of the monitor 5.

摘要： PURPOSE:To prevent a wall surface climber from falling down by equipping it with a function to detect a state of adsorption as it moves up and down. CONSTITUTION:A wall surface climber has a removable actuator for a magnet fixed to the frame of a leg 16 and a magnet 14 to cling on a wall surface. A magnetic sensor 20 confirms that the magnet 14 clings on the wall surface. Climbing movement is made by repeating the following steps: with the magnet 14 of one leg clinging on the wall surface, the magnet 14' of the other leg clings, and, after confirmation of the state of its clinging on the wall surface by use of the magnetic sensor 20, the magnet 14 of the first leg is raised and moved toward the desired direction of movement. When the state of clinging is determined to be imperfect by the magnetic sensor, the subsequent movement is discontinued and inhibited, with no fear of the climber falling down.

摘要： PURPOSE:To feed a speed back with excellent precision on the basis of position information by fetching displacement twice at different fetch timing within a specific time, and estimating and feeding the displacement and speed back on the time interval. CONSTITUTION:The rotational position of a rotating body 502 is detected by a reversible counter 504. A read of position data as displacement is made twice within one sample time tau. The data is read in a sampler 505 at points alphatau and betatau synchronously with the timing signal of a timer 506 and recorded in a memory 507. Consequently, a speed estimation part 508 estimates the speed at the time of the completion of a sample section, and a displacement estimation part 509 estimates the displacement. A manipulated variable determining arithmetic part 510 calculates the manipulated variable in the following section on the basis of the estimated displacement and speed, and a current output part 511 receiving it flows an armature current corresponding to the manipulated variable to a DC motor 501 at the time of the sample section completion synchronously with the timing signal of the timer 506.

摘要： PURPOSE:To stabilize the operation of permanent magnets in mounting and demounting onto a wall surface and the shift on the wall surface by installing supporting points for supporting the attraction force generated between the permanent magnets and the wall surface when the permanent magnets of absorbing units are mounted and demounted, into the absorbing units. CONSTITUTION:A wall-surface traveling machine is equipped with a pair of absorbing units 31 and 41 in front and in rear. Said absorbing units 31 and 41 are shifted back and forth by the drive of propulsion mechanisms 38 and 48 by actuators 37 and 47. Said absorbing units 31 and 41 are equipped with permanent magnets 32 and 42 attached onto the wall surface 40, actuators 33 and 43 for mounting and demounting the permanent magnets 32 and 42 onto the wall surface 40, and supporting points 34 and 44 for supporting the attraction force in the case when the permanent magnets 32 and 42 are mounted and demounted. By the installation of the supporting points 33 and 43, the magnetic attraction force generated in the case when the permanent magnets 32 and 42 are mounted and demounted is not transmitted to a body 39 balanced in the closed system surrounded by the frame 41 of the absorbing unit and the wall surface 40.

摘要： PURPOSE:To estimate the speed with high accuracy and without effect of external disturbance or the operation quantity by providing a new point of measurement within a sample section of a secondary sample value control system. CONSTITUTION:A drive part 141 of a manipulator consists of a DC motor 142, a rotary encoder 143 and an output shaft 144 and contains no speed sensor. The pulse signal obtained from the encoder 143 is sent to a sampler 146 via a counter 145. The obtained information thetak+alpha and thetak+beta are once stored to a memory 147 and then sent to an operator 148. The operator 148 uses these two inputs to calculate a 1st order differential member in a 2nd order differential equation and obtains the estimated value of a state variable at the starting time point of the following sample section. This estimated value performs the speed feedback to the motor 142 via a D/A converter 149 and a current amplifier 150.
