摘要： PURPOSE:To lighten a cage and improve the rigidity by sandwiching a honeycomb plate between an upper and a lower metal plates to be bonded, and interposing a frame-formed fixing member for surrounding the honeycomb plate in the peripheral part between the metal plates for bonding to form a cage floor, and fixing the cage floor to a floor frame and a skirting board with the upper and the lower metal plates. CONSTITUTION:A lower metal plate 31a having an area as same as a cage floor frame 20 is placed on the cage floor frame 20, and a honeycomb plate 22 having an area as same as the inside area of a cage chamber is placed on the lower metal plate 31a for bonding. A rectangular frame fixing member 32 is fitted so as to surround the periphery of the honeycomb plate 22 to prevent deformation of the honeycomb plate 22. An upper metal plate 31b is placed on the honeycomb plate 22 and the fixing member 32 for bonding so as to cover them, and a plywood 23 and a glazed tile 24 are bonded. The floor plate 20 and the skirting board 25 are bonded to the fixing member 32 with bolts. Consequently, deflection to be caused by offset of a load is absorbed with the tensile force of the metal plates 31a, 31b to maintain the rigidity.

摘要： PURPOSE:To obtain a superconductor having large critical current density by hot-rolling a sintered body at a temp. or high for causing plastic deformation and at a temp. not higher than m.p. CONSTITUTION:Powder of yttrium oxide (Y2O3), barium carbonate (BaCO3) and copper oxide (CuO) is weighed at the rate of composition ratio of Y1Ba2Cu3 O7-x respectively. The powder for a raw material is sufficiently mixed and thereafter roasted. Then this powder is pressure-formed into a rod shape and calcined e.g. at 930 deg.C in the oxygen atmosphere. When bending test is performed at high temp. for this sintered body while changing the temp., plastic deformation is caused at 800 deg.C or high. then the obtained sintered body is heated e.g. at 900 deg.C and hot-rolling is performed therefor. The sintered body after hot- rolling is formed into an electrode by utilizing ultrasonic soldering. Further m.p. of Y-Ba-Cu-O-based ceramics is about 960-980 deg.C and therefore hot-rolling is performed at the temp. not higher than this temp.

摘要： PURPOSE:To measure embrittlement using a fine metal piece, by calculating a relational expression of preliminarily obtained breaking load, breaking energy and ductile fracture rate with fracture transition temp. and calculating the fracture transition temp. of a member to be measured to the values measured from said expression. CONSTITUTION:The fine test piece collected from a member to be measured and having a notch formed thereto is cooled to testing temp. and bending load is applied to the cooled test piece by a load applying apparatus 9. The displacement and load until the test piece reaches destruction are detected by a load displacement detector 10 and a breaking load measuring device 12. The breaking load and the displacement to each load are integrated by a breaking energy measuring apparatus 11 to calculate the breaking energy absorbed by the test piece. The ductile fracture rate of the fracture of the destructed test piece is measured by a fracture measuring apparatus 13 and these detected values are inputted to an analyser 14 to be substituted for the relational expression of preliminarily obtained breaking load, breaking energy or ductile fracture rate with fracture transition temp. to calculate the fracture transition temp. of the test piece. By a rise in said temp., the embrittlement degree of the member to be measured can be judged.

摘要： PURPOSE:To keep pressure welding force over a long time by mounting a hydraulic cylinder on a pressure welding load to apply the welding pressure to a laminate structure, and applying reaction force of the pressure welding force to an insulating band ring as tensile force. CONSTITUTION:A device 6, a heat sink 7, a countersunk spring, a press plate 9, etc., are set to pivot a bolt 5 by a predtermined angle and bring a laminate slight pressure welding with the bolt 5, and thereafter a set of two hydraulic cylinders 4 are inserted and mounted along a U-shaped mount groove formed in a pressure welding load 3 from the upper and lower portions thereof. Pressure is simultaneously applied to the four hydraulic cylinders 4 to extend a piston rod 13 and bring it into contact with a press plate 9. Once the device 6 is subjected to pressure welding through the press plate 9 and a conductor 8, the countersunk spring located at the right end is contracted to form a gap between the bolt 5 and the press plate 9. Thereupon, as a set pressure welding load is attained, the bolt 5 is rotated and brought into contact with the press plate 9 whereby the bolt 5 is clamped. Accordingly, at least two hydraulic cylinders ensure loading of well-balanced pressure welding force.

摘要： PURPOSE:To keep chemical stability while keeping long-term reliability structurally by providing a large number of fine piercing holes to the outer panel bonded to one surface of a honeycomb panel by drilling. CONSTITUTION:Veneer plywood 2 is superposed on a decorative tile panel 1 from below as a substrate material and a plastic honeycomb panel 3 is arranged thereunder and an outer panel 4 made of a metal having high rigidity is superposed on the under surface of said honeycomb panel 3. These respective panel materials are bonded by epoxy or chloroprene type adhesive layers 5a, 5b, 5c and a large number of fine piercing holes 6 are preliminarily provided to the outer panel 4 by drilling. That is, holes having a diameter of about 0.3mm are provided at intervals of 5mm in longitudinal and lateral directions. As a result, even when the org. flux remaining in the adhesive layer 5c is volatilized, the org. flux is diffused and discharged to the outside through the holes 6 without being accumulated in the air layer 3a of the honeycomb panel 3.
