    • PURPOSE:To improve efficiency of energy transfer of each stage by connecting a reactor which can charge a value of inductance between a capacitor at a magnetic pulse compression circuit and a pulse transformer connected to a charge power source. CONSTITUTION:Electric charge stored in capacitors 8, 9, 10 of a charge power source 1 is charged to a capacitor 16 of a first stage of a magnetic compression circuit through a pulse transformer 11 and a reactor 23 equipped with a tap at a specified frequency. A voltage rises to the capacitor 16 at the frequency. When it attains a saturated voltage of a saturable reactor 19 of the first stage, electric charge is transferred to a capacitor 17 of the next stage through a reactor 24 equipped with a tap and the reactor 19. Similarly, electric charge is transferred to a capacitor 18 of a third stage through a reactor 25 equipped with a tap and a saturable reactor 20. Since a saturated voltage thereby becomes a maximum value of an input voltage, efficiency of energy transfer of each stage is improve.

    • PURPOSE:To adjust a magnetic compression circuit input frequency while easily adjusting saturation voltage value of a saturable reactor by providing capacitors for a circuit frequency adjustment in series to each stage capacitor of a magnetic impression circuit while providing capacitors for circuit frequency adjustment in parallel to each stage capacitor. CONSTITUTION:A capacitor 23 for circuit frequency adjustment is provided between a pulse transformer 11 and a capacitor 16 on a first stage of a magnetic compression circuit. The charge stored in the capacitors 8, 9 and 10 of charge power supply is given to the first stage capacitor 16 of the magnetic compression circuit and to the capacitor 24 through a pulse transformer 11 and the capacitor for circuit frequency adjustment with certain frequency. When voltage of the first stage capacitor 16 of the magnetic compression circuit rises with that frequency to reach saturation voltage of the first stage saturable reactor 19, charge moves to the next stage capacitor 17 and to the capacitor 26 for circuit frequency adjustment through the capacitor 25 for circuit frequency adjustment and the saturable reactor so as to be finally inputted to the discharge part through a saturable reactor 21.

    • PURPOSE:To simplify an attribute input by inputting attribute information in one time, inputting the necessary number of devices and preparing the number of devices to be desired by users when the title device belongs to the same type which is used for the analysis of a constitution problem by an inference and has the same constituting element. CONSTITUTION:A knowledge storing part 11 stores a production rule an inference rule composed of a condition part and a resolution part as a knowledge. According to user input information inputted from an input part 13 and stored to a user input storing part 14 and the inference rule to be stored in the storing part 11, an inference processing part 12 executes a prescribed inference processing while the input of the information is stimulated through an output part 15 is necessary. Here, concerning the constituting element which constitutes structure to be analyzed, a data attribute storing part 16 stores the name of the attribute or the input form of the attribute at every type. When the attribute information of the type or the number, etc., are needed, an inference processing part 12 refers the data attribute storing part 16 and determines the input form of the attribute information. Then, the input of the attribute information is stimulated to the user and the inference is proceeded based on said attribute information.

    • PURPOSE:To prevent the generation of a buckling, by using a material the thermal expansion coefficient of which is smaller than that of seal diaphragms at a diaphragm joint part of a body to join both components under a high temperature than the maximum application temperature of this sensor. CONSTITUTION:A fluid pressure Pa and Pb introduced from a pressure introduction port 11a and 11b are transmitted to one side and the other side of a pressure sensitive element 4 through seal diaphragms 3a and 3b and sealed liquid 9a and 9b and a pressure difference being detected is converted to an electronic signal with the pressure sensitive element 4 to be taken outside through a preamplifier 7 or the like. Then, the diaphragms 3a and 3b are made up of an amorphous alloy while the body 2 is made of invar or the like with a thermal expansion coefficient smaller than that the amorphous alloy and as the jointing of the both is performed under a temperature condition, slightly higher than the maximum application temperature of a differential pressure transmitter, contraction of the body 12 is always smaller than that of diaphragms 3a and 3b. Therefore, a radial tension always working on the diaphragms 3a and 3b eliminates the possibility of buckling.
