    摘要: A slip casting mold consisting essentially of a gypsum mold, which contains a water-insoluble organic material, more particularly, a water-insoluble vegetable material such as cellulose, or which further contains glue in addition to the water-insoluble organic material. Since the strength of the casting mold is reduced markedly by heating, a cast article requiring a core (or master mold) having complex shape can be obtained extremely easily.

    摘要: In a forming method and a mold wherein a slip is cast into the mold and wherein the mold is removed after hardening of the slip, the mold is patterned by the use of a water-soluble binder. The mold absorbs a water content in the slip to soften and to become easy of removal, while the slip has the water content absorbed to harden promptly. Therefore, the forming method and the mold are especially suited to produce a cast article of complicated shape.

    摘要: In a method for forming a cast article by slip casting through casting of a slip of powders of ceramics, etc. as disporsed in a solvent such as water, etc. into a solvent-absorbable, porous casting mold of gypsum, etc., the casting mold as made is heated to considerably lower the strength of the casting mold in a shape-maintainable range, the slip is cast into the cavity of the casting mold and after solidification of the slip into a green body the casting mold is removed to obtain a defect-free green body. The casting mold can be removed with much ease.

    摘要: In a casting method comprising casting a slip containing water or an organic solvent as the medium into a mold and removing the mold after solidification of the slip, use of a mold formed with an organic binder soluble in the medium of the slip allows the slip to quickly solidify and afford a green body due to absorption of the medium in the slip by the mold. In this case, the mold softens with loss of the binding power thereof simultaneously with the absorption of the medium. Therefore, no cracks appear at all in the green body, and removal of the mold is very easy.

    摘要: A magnet pump has a magnet coupling for magnetically coupling an inner ring yoke and an outer ring yoke so as to magnetically transmit a torque from driving part to driven part of the pump to rotate the driven part. The magnet pump comprises magnetized magnet pieces bonded to the outer peripheral surface of the inner ring yoke and magnetized magnet pieces bonded to the inner peripheral surface of the outer ring yoke; non-magnetic cylindrical covers covering the surface of the inner ring yoke carrying the magnet pieces and the surface of the outer ring yoke carrying the magnet pieces, respectively; and mold resin parts filling the gap between the surface of the inner ring yoke and the associated non-magnetic cylindrical cover and the gap between the surface of the outer yoke ring and the associated non-magnetic cylindrical cover. Also disclosed are a method of producing the magnet pump in which the non-magnetic cylindrical covers are used as molds, and a nuclear reactor equipment in which the magnet pump is used as a coolant circulation pump.

    摘要: A mixture of ceramic particles (such as SiC particles) with metallic powder (such as iron-base particles, e.g., stainless steel particles) is placed in a predetermined position of an internal wall of a mold and a molten metal (e.g., molten iron-base metal, particularly molten cast iron) is poured into the mold. In this manner a wear-resistant layer is formed in a necessary portion on a surface of the casting at the same time when casting is conducted.
