摘要： PROBLEM TO BE SOLVED: To provide a grain-oriented solidification casting apparatus with which cooling effect is increased in the case that molten metal poured into a mold is subjected to the grain-oriented solidification. SOLUTION: The molten metal 32 held in a cavity 21 of a mold 20, is subjected to grain-oriented solidification by drawing out the mold 20 disposed at the periphery in a prescribed range from a heating chamber 10 heating the metal for casting a cast product 31 to not lower than the melting temperature. This grain-oriented solidification casting apparatus 100 is provided with a driving rod 42 drawing out the mold 26 from the heating chamber 10, a gas nozzle 52b for rapidly cooling the mold 20 by injecting cooling gas from the inside in the prescribed range disposing the mold 20 and a gas nozzle 52a for rapidly cooling the mold 20 by injecting the cooling gas from the outside in the prescribed range disposing the mold 20. Further, a baffle 15 which does not move even if the driving rod 42 is ascended/descended, is provided and this baffle 15 shuts off radiated heat from the heating chamber 10. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To provide a simulator for casting process and a judging method therefor capable of making an optimum casting plan based on a new evaluation index for casting defects.
SOLUTION: An analytical technique for segregation-convection based on a segregation-convection solidification model and an analytical technique for crystal growth based on nucleation-crystal-growth model are simultaneously used every time step. Concentration, speed of flow, temperature, solidus rate, solidification structure, crystal orientation, dendrite arm spacing, and nucleation site are simultaneously output. The existence of casting defects is estimated from the index of casting defects which has been calculated based on them. Not only by the aforementioned casting process simulator, but also from the calculated concentration and temperature by a casting process simulation based on an arbitrary casting plan, the freckle defect evaluation index (Rayleigh Number), in which the segregation and flow of molten metal are considered, and the defect evaluation index for foreign crystal, in which the nucleation mechanism of foreign crystal being considered, are simultaneously evaluated so as to judge the quality of the casting plan.

摘要： PROBLEM TO BE SOLVED: To lessen and prevent the adhesion of scale, such as magnetite, in water in atomic power, thermal power, chemical plants, etc., by forming metal oxidized films which have crystal structures different from the scale, i.e., cubic type crystals, have face bearings to make the oxygen arrangement point- asymmetrical and of which the metal atom species are chromium. SOLUTION: These metal oxidized film materials on apparatus surfaces are metal oxidized films which have the crystal structure different from the scale particle, has the face bearing to make the oxygen arrangement point- asymmetrical and of which the metal atom species are the chromium or titanium. If the metal oxidized films satisfying these conditions are formed, the energy barriers by the coulomb repulsion between the scale film boundary oxygen are easily formed and the iron oxide scale adhesion is suppressed. If the surfaces of the plant apparatus are coated with chromium, and the chromium is subjected to an oxidation treatment, the chromium oxide films (hexagonal crystals) are formed thereon. The adhesion of the scale of the iron oxide, etc., may be lessened and prevented by these films.

摘要： PROBLEM TO BE SOLVED: To theoretically evaluate the presence of adhesion energy or adhesiveness by estimating the presence of adhesiveness and the intensity of adhesion from the total energy distribution to the distance between the surfaces of two materials. SOLUTION: A first reading means 11 reading the compsn. of a given objective material and the crystal structure thereof in an operation system 14, a reading means 12 determining all of mutually acting energy parameters between two atoms of the same kind or a different kind related to the objective material to read them in the operation system 14, a third reading means 13 reading material interface atomic structure model data, an operation means 14 calculating the material interface total energy to the distance between the surfaces of materials on the basis of the sum total of mutual energies between two atoms of the same kind or a different kind and an evaluation means 15 evaluating adhesion energy from the total energy distribution are provided. Differently from a conventional method, if the crystal structure and compsn. of a material are cleared even if the adhesion strength between a different kind of materials is not actually measured, the adhesion energy corresponding to adhesion strength or the presence of adhesiveness can be theoretically evaluated.

摘要： PROBLEM TO BE SOLVED: To estimate an accurate film forming rate and physical properties in the film forming processes of an amorphous silicon thin film. SOLUTION: This simulation method for film formation includes the following processes. In a first process, incident active seeds supplied form a film forming atmosphere, the temp. of the incident active seeds and the substrate temp. are determined. In a second process, movement of one atom in the surface reaction and deposition process of lots of incident active seeds on a substrate is traced at certain intervals of time by using a molecular dynamic method based on the atomic force expression of the silicon-hydrogen system under the determined conditions to obtain the coordinate and velocity of each atom. Then the film thickness produced by deposition of a part of the incident active seeds, the number of whole silicon atoms in the deposited film, the number of whole hydrogen atoms, the number of quadridentate silicon atoms in the deposited film, the number of silicon atoms bonded to one hydrogen atom, and the number of silicon atoms bonded to two hydrogen atoms are calculated based on the obtd. coordinate of atoms. Then the film forming rate and physical property in the film forming process (proportion of defects, hydrogen content and SiH2 /SiH ratio) are obtd. In a third process, the obtd. film forming rate and physical properties of the film forming process are outputted.

摘要： PROBLEM TO BE SOLVED: To restrain loss resulting from a strut extending in an operation fluid of an axial-flow turbine low in either of cases with rated load or partial load. SOLUTION: The strut 20a extends to cross a flow of the operation fluid of the axial-flow turbine. The strut 20a is separated into a front part 21 and a rear part 22. The angle of the rear part is not changeable but the angle of the front part can be adjusted around an extending axial line. The front part 21 changes its angle to face the flow of the operation fluid. Thus, a section area shape of the strut 20a becomes a wing shape with a back surface and a ventral surface and the operation fluid smoothly flows along the wing shape without causing peeling.
