摘要： PURPOSE:To provide the accurate internal shape of a rubber mold by means of simulation by providing a shape data input means, a separating means to divide the rubber mold shape into a number of finite elements, a physical property storing means, a treatment pattern storing means, a deformation analysis means for carrying out deformation analysis and a deformed rubber mold shape output means. CONSTITUTION:An initial shaping of a rubber mold is inputted by an operator. When the initial shaping plan of the rubber mold is inputted, the shape of said initial shaping plan is separated by a computer. When the separating treatment is completed, a physical property value corresponding with the quality of a rubber material to be used or powder to be treated is selected. The same process is carried out for treatment patterns. Boundary conditions and other CIP conditions are put in successively, and then deformation analysis is carried out by the infinite analysis method. Whether a simulation shape retained on VDT is similar to the shape of a powder molded product to be desired or not is determined.

CONSTITUTION:The upper and lower ring bodies 3 having a sliding and face 4, sliding inner face 5, circular arcuated outer peripheral face is provided concentrically and slidably on the upper and lower both end faces of the cylindrical shell part 2 in an uniform thickness. The upper cover body 6 having a vent 7 at the center part is closely engaged slidably in the axial direction with the sliding inner face 5 of the upper ring body 3 and a bottom cover body 8 is closely engaged similarly with the sliding inner face 5 of the lower ring body 3 as well. Moreover the upper outer periphery of the upper cover body 6 and the outer peripheral part on the upper end face of the shell part 2 are connected by a cup like upper shielding member 9 to hold a perfect air tightness and the space between the bottom cover body 8 and shell part 2 is similarly connected by a lower shielding member 10. A forming container 1 is thus formed, a powder material 3 is filled and stored in the hollow part 12 thereof and by executing the forming of the powder material 3 by a hydrostatic pressurizing device the generation of a distorted deformation on the pressure molded part is prevented.

摘要： PURPOSE:To improve heat resistant impact by a method wherein a compression initial stress is exerted on a covering member made of ceramics, a heat insulating layer is formed between the covering member and a reinforcing member made of a metal disposed in the covering member, and a compression stress is generated even in a steady state. CONSTITUTION:When a part is applied for a vane part 2 and a stator blade 1 for a gas turbine formed with mounting parts 3 and 3 formed at both ends thereof, the blade part 2 is formed such that a metallic liner 6 serving as a reinforcing member is inserted and situated in a ceramic shell 4 serving as a covering member with a heat insulating layer 5 therebetween. In this case, the shell 4 is compressed and nipped by means of a mounting part 3 so that a compression initial stress is generated under a room temperature state at the shell 4. The heat insulating layer 5 is formed between the shell 4 and the liner 6 so that a temperature difference is produced under a steady using state between the shell 4 and the metallic liner 6. This constitution enables the com pression stress of the shell 4 to be held in a given range by means of a tempera ture difference, a difference in the coefficient of thermal expansion, and a sec tional area ratio between the shell 4 and the liner 6.

摘要： PROBLEM TO BE SOLVED: To prevent, at low cost, crack of the corner portion of slab and horizontal crack in secondary cooling during continuous casting by retaining a solidified shell portion in a particular area in slab between two particular temperatures for a particular time. SOLUTION: A solidified shell portion or a short side solidified brittle shell area existing within a slab to form a substantially isosceles right triangle with the short side of the slab as the base and in the range of 40 to 70 mm from the short side of the slab gives an important effect in causing the horizontal crack of the slab. That is, the longer the residence time in the brittle temperature area of this portion, the longer the horizontal crack tends to become. The brittle temperature area is defined as temperature between the solidus line temperature and solidus line temperature -100 deg.C. If the residence time is made to be 100 seconds or less, the horizontal crack is about 30 to 33 mm, and at this level, the horizontal crack after hot rolling will not be caused. In operation, this residence time is preferably 15 to 50 seconds.
