摘要： PURPOSE:To enable manufacture of a large scale precision casting blade in the manufacture of a uni-directional solidified blade or a single crystal blade used for a steam turbine or a gas turbine for air craft or for industry. CONSTITUTION:A columnar tower is assembled with wax material so as to surround the wax pattern 2 of the blade and after refractory material is applied on the surface of the tower and dried, the wax material is melted out to form the combined mold of the blade and the columnar tower. Successively, molten metal is poured into only the mold for the blade 1 and thereafter, the combined mold of the blade and the columnar tower is taken out of a casting furnace so as to solidify the molten metal.

摘要： PURPOSE:To effectively utilize material strength being suitable to the necessary characteristics in each part of a casting product and to improve creep character istic, fatigue strength and toughness by combining merits of respective casting method by using two or more kinds of the casting methods. CONSTITUTION:In each part in the integrated machining member, while manufac turing each part with the casting methods for giving the characteristics matching to need at each part in these, the process for integrating by complexing these is executed. Therefore, in the case of exemplifying a turbine wheel for small size turbine, a blade part corresponding to a second member planted may be cast with unidirectional solidification in order to utilize this alloy characteristic. Further, a disk part corresponding to a first member may be cast as making fine crystal with rotary solidifying method in order to satisfy the characteristic to be needed. In this result, the blade part has metallurgical structure with the crystal grown in stress direction and improved in creep resistance and the disk part can have uniform characteristic to the whole direction.

摘要： PROBLEM TO BE SOLVED: To provide a method and device for simulation testing on the centrifugal stress of a turbine blade, accurately testing the inherent defect of a portion with erosion-resistant material welded and overlayed to the boundary between a blade and a shroud in a single turbine blade by a static method.
SOLUTION: While the blade root 18 of the turbine blade 10 is loaded in a blade root retaining portion 20 and the fitting looseness of the blade root 18 into the blade root retaining portion 20 is removed by adding a force in a centrifugal direction from the outside of the blade root retaining portion 20 to the blade root 18, a pressing force equivalent to a centrifugal force during operation of a turbine is added to the shroud 12, and while the portion of the shroud 12, opposed to a portion applied with the pressing force, is fixed, the pressing force equivalent to the centrifugal force and the torsional return deformation of the turbine blade 10 caused by the operation of the turbine is added to the shroud 12. Then, the simulation testing is performed on the centrifugal stress of the welded and overlayed portion.

摘要： PURPOSE:To eliminate high stress which in a hull transverse bulkhead structure suitable for use in a tanker was conventionally generated at the tie-in portion of the lower end of a vertical warp-proof material extending along a hull center line and a bottom structural member, particularly owing to a difference in loaded state between tanks in front of and behind a hull transverse bulkhead. CONSTITUTION:In a hull transverse bulkhead 6, part of the lower end portion of a center-line vertical warp-proof material 8 extending along a hull center line 1 is removed and plural stages of horizontal warp-proof material 12 are used to warp-proof the removed part of the transverse bulkhead 6. Even if one of tanks in front of and behind the transverse bulkhead 6 is full and the other is empty, high stress which was conventionally generated at the tie-in portion of the lower end of the center-line vertical warp-proof material 8 and the upper end of a center-line large bracket 11 is completely eliminated.

CONSTITUTION:A shell 4 is provided on the inside surface of a bearing member 3. An oil pocket 5 for assuring a prescribed quantity of supplied oil is provided inside the rear part of a loaded surface 3a, on which oil film pressure is caused. A plurality of oil supply holes 6 opened at a regular spacing in the axial direction and extending into the ends 5a of the oil pocket 5 at the loaded surface 3a are connected to an oil tank 9 through pipes, a cooler 7 and an oil pump 8. Oil controlled to a prescribed temperature is supplied into the gap between the shell 4 and a sleeve 2 on a rotary shaft 1 through the oil supply holes 6 and the oil pocket 5 and revolved together with the rotary shaft 1 so that the oil is brought to the loaded surface 3a. Since the gap between the sleeve 2 and the shell 4 becomes smaller, the oil film pressure is caused.

摘要： PROBLEM TO BE SOLVED: To provide a sterilizer that can be improved in sterilizing effect by utilizing physical energy.
SOLUTION: This sterilizer is constituted of a container 1 in which plasma P is generated, a supporting device 7 which is disposed in the container 1 and holds an object T to be sterilized in the container 1, and power sources 23 and 46 which project electric power not resulting from the plasma P upon the object T. In the peripheral area of the object T, a radical is generated, because a gas 13 or 14 in the container 1 is polarized and, in addition, excited by the electric power. As the electric power, a high frequency 45 or laser beam 25 can be utilized appropriately. The microbial organisms adhering on the surface of the object T become extinct due to the polarization or radical.
