摘要： PURPOSE:To ensure the simulation with the optimum arithmetic block by securing the alteration in accordance with the progress of the simulation for the arithmetic block connected in the optimum way according to the conditions of the waveforms or the like which simulate each arithmetic element of the DDA (digital differential analyzer). CONSTITUTION:Timer 2 is actuated by operation start signal 1, and at the same time DDA11 starts the operation. Coincidence circuit 4 compares the output given from timer 2 with alteration time value from RAM7. And when the coincidence is obtained through the comparison, transfer command signal 5 is delivered to transfer circuit 10. At the same time the, comparison is started with alteration time value T2. On the other hand, circuit 10 reads out alteration information UB1 from RAM8 and then sets it to DDA11 as well as gives preparation to the transfer of alteration information UB2 at time value T2. And DDA11 starts the operation via the new arithmetic block altered by information UB1. In such way, the operation is repeated to complete the operation up to alteration time Tn. Then at alteration time Tn+1, circuit 4 delivers stop signal 12, and thus the timer 2 operation is stopped along with the operation of DDA11. Thus all operations complete.

摘要： PURPOSE:To make it possible to visually inspect many kinds of pipes by a remote operation with the use of a single device by giving five degrees of freedom to an inspecting head and arranging an approach sensor so that the inspecting head is remotely operated by a control device. CONSTITUTION:Five degrees of freedom are afforded by a feed axis 15 for moving an inspecting head 20 along a piping axis, an axis 14 for turning the head 20, a rocking axis 13 for changing the angle of inclination of a portion including the axes 14 and 15, an axis 12 for extending and contracting the foregoing portions, and an axis 11 for turning all of the foregoing portions. There are arranged on the inspecting head 20 at the leading end a video optical system for illuminating an object surface to receive the video image and two approach sensors 22a and 22b for detecting the relative distance between the inspecting head and the object surface. The input from the video optical system is transmitted through an image guide to an ITV27 and is fed to a remote TV monitor. A controller actuates the respective axes through an inspecting mechanism 10 in such a preset operating sequence as is programmed in advance so that the indexing signals of the respective axes are compensated for the inspection in response to the output of the approach sensors 22.

摘要： PURPOSE:To control continuously the track of a robot, which is provided with plural revolving shafts, with a high precision by using the deviation vector between the current position and the target position of the robot as a target position vector. CONSTITUTION:A target position Xv from a target position generating means 400 is inputted to a speed vector generating means 401. A coordinate converting means 407 converts a positional displacement theta in the coordinate system peculiar to the robot to a current position X in a prescribed space coordinate and supplies it to the speed vector generating means 401. The generating means 401 outputs a target speed vector on a basis of the deviation vector between the target position Xv and the current position X. This target speed vector is converted inversely to the coordinate system peculiar to the robot by an inverse coordinate converting meand 402 and is inputted as an operation vector to a servomechanism. Thus, the track of the robot provided with plural revolving shafts is controlled continuously with a high precision.

摘要： PURPOSE:To decrease damage to an objective material at its conveyance and stably convey and stop the material in a coveying device of gravitational drop type, by utilizing electrostatic force of attraction for applying lifting power in a conveying part while damping force in a braking part to the material. CONSTITUTION:If voltage is applied between a electrode plates 6, 7, electrostatic attraction is caused between the both electrodes to act lifting power on a water 3 transferred on a conveying route, in this way, frictional resistance of the wafer 3 caused by its sliding movement can be decreased, and the wafer 3 can be conveyed for a relatively long distance only by applying a fixed initial speed. If voltage is applied to a pair of electrode plates 12, electrostatic attractive force is generated between the wafer 3 and semiconductive materials 13 to increase frictional resistance of the wafer 3, and the wafer 3 can be stopped to a prescribed position by controlling the frictional resistance in accordance with sliding motion of the wafer 3.

摘要： PURPOSE:To realize use even under the vacuum condition and reduce damage on an object at the time of chucking, by arranging plurality if semiconductor dielectric materials on the base surface in such a way that these are electrically insulated, dividing them into two groups, applying a voltage across the one and the other groups and by allowing change of attitude of them. CONSTITUTION:A plurality of semiconductors 1 providing electrode plate 3 are insulated from each other and arranged on the surface of base 2. The base 2 is coupled to a supporting member 5 through a spring 6 used as a buffer material so that it can change the attitude. Thereby, when a semiconductor 1 is in contact with an object 4, the atitude of each semiconductor 1 and a shape of object 4 can be corrected so that the surface of each semiconductor 1 is completely in contact with the object 4. When a voltage is applied under this condition, an electrostatic attracting force is generated between the semiconductor 1 and object 4, chucking an object 4.

摘要： PURPOSE:To record information before and after the generation of a failure with less storage capacity, by performing recording at normal operation while revising within a prescribed storage time and recording within a time width less than said time from the generation of a failure. CONSTITUTION:A picture and audio signal fetch controller 4 scans M kinds of picture signals and N kinds of audio signals in high speed and gives them to a picture and audio signal storage controller 5. The controller 5 stores the scanning data of the M+N kinds for a time T with the endless system at normal operation as shown in figure. Further, the controller 5 inputs a trigger signal 10 of failure detection and temporarily stops with recording only for a prescribed time width T1. Then, the data before the triggering is recorded for a time width T2 and the data after the triggering is recorded for the time T1. This recording is transferred to a recorder 6 and the operation information before and after the generation of failure can be displayed on reproducers 8 and 9.
