摘要： PROBLEM TO BE SOLVED: To provide a screw cooling pipe with excellent characteristics in its heat removing property used as a cooling pipe for a diverter plate which forms the outer wall of a container for surrounding plasma generated in a nuclear fusion reactor. SOLUTION: In the screw cooling pipe having screw thread shaped serrate fins formed on the inner surface thereof, the configuration of the screw thread is optimized. Thus, the beat removing property of the cooling pipe is improved, the pumping power of cooling fluid is reduced and the sudden rise of temperature upon turning off a burner is detected so that a pipe wall can be prevented from being melted.

摘要： PROBLEM TO BE SOLVED: To provide a first wall and a divertor plate which are installed so that the wall and divertor can be faced oppositely to the plasma of a nuclear fusion device and has a high thermal shock resistance. SOLUTION: A carbon fiber-reinforced composite carbon material is integrally constituted by laminating a unidirectional carbon fiber-reinforced material and tri-directional carbon fiber-reinforced material upon another in the thickness direction so that the carbon fibers substantially oriented in the thickness direction can become continuous in the thickness direction. A first wall and a divertor plate are positions adjacently to the unidirectional carbon fiber- reinforced section so that the wall and plate can be faced to the plasma of a nuclear fusion device constituted mainly of the carbon fiber-reinforced composite carbon material in which a metal is joined to one surface of the unidirectional carbon fiber-reinforced section substantially perpendicular to the thickness direction of the section or a metallic tube is buried in the tri-directional carbon fiber-reinforced composite carbon material.

摘要： PURPOSE:To enhance the reliability in the protective operation being conducted when two operating means are operated by performing the 2-out-of-4 logic for the quadrupled status amount signals from sensors in a quadrupled signal processing system thereby producing a trip signal. CONSTITUTION:A signal processor 1A is provided with digital trip modules DTM-A1-A4,..., DTM-N1-N4 connected, respectively, with sensors A1-A4,..., N1-N4. The DTM-A1-A4,..., DTM-N1-N4 are connected, respectively, with 2-out-of-4 logic circuits 29A,..., 29N. The 2-out-of-4 logic circuits 29A,..., 29N are connected with a 1-out-of-n logic circuit 30. Other signal processors 2A, 3A, 4A have similar constitutions. Upon delivery of a trip signal from at least one of (n) 2-out-of-4 logic circuits 29A,..., 29N, the 1-out-of-n logic circuit 30 delivers a trip signal (a) for opening a scramming solenoid valve thus scramming the nuclear reactor.

摘要： PURPOSE:To cope with various types of instructions by means of input sentences in various expressions by preparing data to which the relation between a standard sentence pattern and instruction contents is applied. CONSTITUTION:In an input sentence analyzing device 3, a morpheme/syntax analyzing part 31 recognizes words included in an input sentence in a natural language by means of an operator/maintenance crew by means of a morpheme/ syntax analysis, and an instruction contents fixing part 32 identifies the instruction contents with the use of the data to which the relation between the standard pattern prepared beforehand and the instruction contents is applied. Next, a necessary information acquiring part 35 uses an information item necessary for the instruction execution prepared beforehand and the data concerning an acquiring method, and acquires information necessary for the execution instruction by referring to the input sentence, an interactive history, etc. Further a corresponding part 34 to function/argument outputs the instruction contents and the acquired information by making them correspond to the function and argument value of each type of a program prepared in a process computer. Thus the input sentence in the various expressions including the omission of a postpositional word, substantive finish, etc. is coped with.

摘要： PURPOSE:To prevent the titled device from being subject to bad influence even when an abnormal test signal is impressed by inputting a test signal for abnormality diagnosis outputted from a signal generating means connected to each control device to a signal selecting device for selecting a proper input signal. CONSTITUTION:A control device 1A outputs a measuring signal for a sensor and also outputs a signal (a) for controlling the opening of valves 13A-13C and the signal (a) is inputted to a majority decision device 10A through a change-over switch SW or the like. The device 10A selects at least two coincident signals output three input signal as a correct signal and outputs the signal. In case of diagnosing the existence of abnormality in the device 10A, the switch SWA is switched and a test signal S is outputted. A diagnosis device 2A compares detecting signals 16A-18a measured by signal detectors 7A-9A with each other. When the patterns of these detecting signals are equal, they are judged as abnormal signals. Since the device 10A is a signal selecting means, the device 10A can be prevented from being subject to the bad influence of an abnormal test signal.

摘要： PURPOSE:To isolate a junction and to omit the step of forming an edge face in the manufacture of a P-N junction type solar cell in which a polycrystalline silicon wafer is used as a substrate by forming newly a P-N junction between a front surface electrode and a rear surface electrode. CONSTITUTION:A P-type polycrystalline silicon substrate 1 is employed (a), an N type layer 2 is formed to form a P-N junction 3 (b). Then, a rear surface electrode aluminum paste 4 and junction isolating aluminum paste 5 are simultaneously printed on the N type layer of the rear surface side (c). Then, a heat treatment is executed. The junction isolating aluminum is diffused with the paste 5 in the substrate by the heat treatment to form a P type layer 8, and a P-N junction 9 which operates as a junction isolation is formed. Simultaneously, the rear surface electrode aluminum paste 4 is also diffused in the substrate to become a rear surface aluminum electrode 7 (d). That is, the junction can be isolated simultaneously upon the formation of the rear surface electrode, thereby omitting the edge face forming step.

摘要： PURPOSE:To inspect a logical function in a small number of test cases by adding a memory contents reading means of a device to be tested and a test pattern generating means which produces the output value of each basic arithmetic element as well as a test input signal to a test device. CONSTITUTION:A test device 1 gives an input pattern to a software logical device 2 and fetches the final stage value of a logic circuit from an output part 23 via a signal input means 15. A memory contents reading means 14 reads the output value of each basic arithmetic element out of an arithmetic element output memory 25 and sends it to a comparison means 16. A variable address memory means 33 stores the address of the memory 25 and the means 14 reads the address of the memory 25 out of the means 33. Then the means 14 reads the output value of the basic arithmetic element out of the corresponding address of the memory 25. A comparison means 16 compares the test results given from both means 14 and 15 with a reference pattern received from a test case selection means 12. The result of this comparison is delivered to a result output means 17.
