    摘要: Proposed is a novel face coat composition having improved stability used in the preparation of a shell-like casting mold for a high melting point metal or alloy by the lost-wax mold method by forming a face coat layer on a wax model using the composition and further forming a backup coat layer thereon followed by removal of the wax by melting and calcination of the shell-like mold formed from the layers. The face coat composition comprises a rare earth oxide powder as the refractory constituent and a binder which is a synthetic resin in the form of an aqueous emulsion, a water-soluble organic polymer in the form of an aqueous solution, a sol of an inorganic oxide such as aluminum oxide, silicon dioxide and zirconium oxide or a combination thereof. A small amount of a powder of rare earth glass can be admixed to the composition so that the face coat layer formed from the face coat composition may have still improved properties. The face coat layer formed from the inventive face coat composition is outstandingly resistant against attack of the high-temperature melt of a reactive metal or alloy so as not to form a reaction-hardened surface layer on the cast body.

    摘要: A static magnetic refrigerator comprising a magnet generating a high-intensity magnetic field, a magnetic working material disposed in the high-intensity magnetic field, a magnetic shield disposed between the magnet and the magnetic working material, and a rotating means for rotating the magnetic shield, the magnetic shield comprising a pair of nearly parallel flat plates or a pair of outwardly curved plates facing each other and made of a superconductor, and the magnetic working material is accommodated in the inner space form by the pair of the flat or curved plates, whereby a magnetization process wherein the magnetic working material is magnetized in the high-intensity magnetic field by way of rotating the magnetic shield at a position allowing the permeation of the magnetic field through the magnetic working material via the pair of the flat or curved plates and a demagnetization process wherein the magnetic working material is demagnetized by way of further rotating the superconducting magnetic shield at another position permitting the shield of the magnetic field via the pair of the flat or curved plates are repeated by the rotating means so that the magnetic working material generates coldness.

    摘要: In a grain-oriented electrical steel sheet having phosphate-based coatings, which contain no chromium and which impart a tension, on the surfaces of a steel sheet with ceramic underlying films therebetween, the coating amount of oxygen in the underlying film is 2.0 g/m2 or more and 3.5 g/m2 or less relative to both surfaces of the steel sheet. Consequently, a grain-oriented electrical steel sheet with a chromium-less coating is provided. The resulting steel sheet has coating properties at the same level as those of a steel sheet with chromium-containing coatings and realizes high hygroscopicity resistance and a low iron loss without variations.
