摘要： PURPOSE:To minimize the frequency or cost of inspection required up to the identification of a fault source by utilizing a fault wave and a network when a single fault occurs to an object under the influence of a fault, and indicating optimal inspection order on the basis of dynamic programming. CONSTITUTION:When a plant is in normal operation, pieces of information on an optimal inspecting equipment T'(Slk) classified by states are stored on a floppy disk FD102. When a fault occurs to the plant, this FD102 is inserted into the disk processor 103 of an optimal inspection order indicating device 101. Then, the contents of the FD102 are transferred to a memory part 105. An arithmetic part 104 utilizes information on the fault rate lambdai of the equipment in the memory part 105 to calculate relative fault probability qi, which is displayed at a display part 109. When an operator need not correct the qi, a current state vector S'lk is found by the arithmeticc device 104 and Slk which is the same as it is searched for in the memory part 105 to find a corresponding optimum equipment T'(S'lk) classified by states, which is displayed at the part 109. The operator inspects the indicated equipment and presses a normal or abnormal button.
摘要翻译：目的：通过在故障影响下对物体发生单一故障时利用故障波和网络来最小化故障源识别所需的频率或成本，并在此基础上指示最佳检查顺序的动态规划。构成：当工厂正常运行时，根据状态分类的最佳检查设备T'（Slk）的信息存储在软盘FD102上。当工厂发生故障时，将该FD102插入到最佳检查指示装置101的盘处理器103中。然后，FD102的内容被传送到存储器部分105.算术部分104利用故障信息记录部105中的设备的速率lambdai，以计算在显示部109显示的相对故障概率qi。当操作者不需要校正qi时，由运算装置104找到当前状态向量S'k， Slk与在存储部105中搜索的Slk相同，以找到由状态分类的对应的最佳设备T'（S'lk），其在部分109处显示。操作者检查指示的设备并按正常或异常按钮。

CONSTITUTION:In welding of austenite base stainless steel pipe 1 to be filled with corrosive material in piping, a build-up weld part 4 of anti-corrosive metal (such as SUS316L, SUS321, etc.) being lower in susceptibility to stress corrosion crack than the pipe 1 is provided on the interior face of the end part of the pipe 1 in the thickness of q for the range up to heat affected zone l due to butt-welding, and solution heat treatment is carried out for 30 minutes at 1050 deg.C to recover the anti- corrosive property of the sensitized part. Next, a beveling 6 is provided, and butt- welding with the same metal as in the previous build-up welding is performed. Since the sensitized parts 3, 3A are covered with build-up weld parts 4, 4', occurrence of stress corrosive crack may be completely prevented.

摘要： PURPOSE:To attain the expression of a 3-dimensioned object with a less amount of calculation by controlling contrast and saturation of a color in several gradation at each dot on a CRT as to express a relative distance of a 3-dimensional object thereby without using complicated algorithm. CONSTITUTION:Color information corresponding to each dot is generated by an operation processor 10 and the generated color information is stored to an address of each dot of display RAMs 50, 60, 70 via a bus transmission line 3,000. The color information is transmitted to a video signal generator 100 via an interface 90 and a bus transmission line 7,000 and the video signal in response to the contrast of each dot is outputted and displayed from the device 100 onto a transmission line 8,000 based on the color information. That is, in displaying the 3-dimension object on a 2-dimension color display 110, the depth of the object and the relative distance between the objects in a 3-dimension space are expressed with less amount of calculation not using complicated algorithm based on the change of the contrast and saturation.

摘要： PURPOSE:To utilize the result of a check on the logical consistency between an event to be generated definitely and an event not to be generated definitely effectively for an analysis of reliability without nullifying the experience and knowledge obtained by the last reliability analysis by checking on the logical consistency between said events, and displaying the contents of logical contradiction if the contradiction is found. CONSTITUTION:A fault tree to be checked and couples of events which never occur within the width of the tree are stored on a magnetic disk 1. An operator actuates a main body through a keyboard 3 to check on whether some tree has consistency with some specific object or not. A computer 2, on the other hand, inputs the tree and the couples of events which never occur at the same time from the disk 1. The result is displayed on the display area of the keyboard 3, so the operator inputs settled fact as to a specific event at a stage 5 over a look at the displayed tree. The computer 2 checks the logical consistency on the basis of those inputs. If some contradiction is found, that is displayed on the display.

摘要： PURPOSE:To improve reliability by switching a pump which is not damaged to the reverse operation during liquid feeding OFF operation, thus preventing the liquid feeding ON-OFF function from being lost by a single damage. CONSTITUTION:When an electromagnetic pump 1 is damaged and ON-operation state is fixed, a pump control circuit 8 sends reverse operation signals into the electromagnetic pumps 1 and 2. The electromagnetic pump 2 performs suction operation. Since the liquid pumped-up by the electromagnetic pump 1 is returned into a liquid metal storing tank 3 through a pipe 9, said liquid is not pumped-up into an atomic pile 4 through a pipe 8. Afterwards, during the time when the electromagnetic pump 1 continues ON-operation, the same operation is repeated. Therefore, even if the electromagnetic pump 1 is damaged and ON-operation continues, the liquid feeding ON-OFF operation can be maintained in the whole system.
摘要翻译：目的：为了通过切换在液体供给关闭操作期间没有损坏的反向操作的泵来提高可靠性，从而防止液体进给ON-OFF功能由于单次损坏而损失。构成：当电磁泵1损坏并接通运行状态时，泵控制电路8向电磁泵1和2发送反向运转信号。电磁泵2进行抽吸运转。由于由电磁泵1抽出的液体通过管道9返回到液态金属储存罐3中，所以液体不会通过管道8被泵送到原子堆4中。之后，在电磁泵1继续打开操作，重复相同的操作。因此，即使电磁泵1被损坏并且继续接通操作，也可以在整个系统中保持液体供给ON-OFF操作。
