    摘要: A surface hardening method, in which a surface layer on a thin steel plate member is stably melted and solidified to provide a high surface resistance against wear includes irradiation with a high density energy beam to melt a process surface portion of the steel member followed by rapid cooling. The melted surface portion includes a fully melted layer and an adjacent imperfectly or partially melted layer. At least the cooling to solidify the molten steel is performed in a short time period less than an austenitic transformation completion time at temperatures below melting, e.g., one-twentieth of the normal austenitic transformation time, and preferably both heating to melt the surface layer and cooling to solidify and harden the surface layer are performed in a time period less than the normal austenitic transformation completion time period. The high density energy beam can be divided to irradiate plural regions to melt the surfaces of the plural regions at the same time. The thermal capacity (or thickness) of the entire steel member can be designed to be as small as four times the thermal capacity of the process portion (or depth of melted portion) and still allow self cooling of the steel member to produce surface hardening. Additionally the melted-hardened surface has improved smoothness such as exhibited by a roughness which is only sixty percent or less of the roughness of non-processed surfaces.

    摘要: In a steel member surface treatment method, only a surface layer portion of the steel member is heated to its melting point or higher to form a melt, by high density energy-beam irradiation. Subsequently, the melted portion is rapidly cooled to a martensitic transformation region, to form a martensitic structure. The temperature increasing rate in irradiation of the surface layer of the steel member is preferably 7500° C./second or greater. Thereby, thermal strain and quenching failure are reduced even if the steel member is a thin plate component and a high production efficiency can be achieved.

    摘要: An incandescent lamp assembly has a generally elliptical vitreous envelope including a cylindrical neck, stem mount with a pair of lead-in wires, and a screw-in base capped on the cylindrical portion of the envelope. The cylindrical neck of the envelope has a circular protruded ring along the entire periphery thereof and in the corresponding position of the screw-in base is provided a concave channel, for a push-in coupling. A flared rim is integrally formed with the concave channel and extends gradually outwardly to bear along the envelope, giving elastic deformation to the upper half of the screw-in base. The lead-in wire is interposed between the cylindrical neck and the screw-in base and fixedly positioned at the circular protruded ring. For prevention of relative rotational movement, heat resistant silicone rubber is applied on the circular protruded ring.

    摘要: The present invention provides a method for producing tagatose crystals from an aqueous system using no organic solvent. In this method, seed crystals of tagatose are added to a tagatose solution in which a tagatose purity of solid contents in the solution is at least 70% and a solid contents concentration in the solution is 60 to 98 mass %, and crystallization of tagatose is carried out by stirring and cooling the solution while keeping a degree of super saturation of tagatose at 1.25 or lower. It is preferred that the solution containing tagatose is a solution containing no organic solvent. It is further preferred that a part of massecuite for which the crystallization is completed is added to a mother liquor so as to produce the tagatose crystals semi-continuously or continuously. It is furthermore preferred that the tagatose crystals formed from the massecuite are separated by centrifugation or filtration and dried to obtain tagatose crystals.
