摘要:
For providing a magnetostrictive film that can exhibit high magnetostrictive properties in the vicinity of zero magnetic field and their manufacturing methods, a magnetostrictive film thermal sprayed on an object under test includes a metallic glass film subjected to thermal processing at a temperature lower than the glass transition temperature and not lower than the Curie point, and shows a linearity between the magnetic field and the magnetostriction in at least a part of the magnetic field from −15 kA/m to +15 kA/m (both inclusive).

A metallic glass laminate of the present invention is characterized in that a metallic glass layer of amorphous phase is formed on the substrate surface, and there is no continuous pore (pinhole) through the metallic glass layer. The metallic glass laminate is preferably obtained by solidification and lamination of at least part of the metallic glass powder in the molten state or in the supercooled liquid state on the substrate surface. Because of the dense metallic glass layer of homogenous amorphous phase, the functionalities of metallic glass such as corrosion resistance and wear resistance can be satisfactorily provided. A thick and a large-area metallic glass layer can be formed. The metallic glass layer can also be formed into various shapes within the supercooled liquid temperature range. In addition, a metallic glass bulk can be obtained by removing the substrate. The metallic glass laminate and the metallic glass bulk are utilized for a fuel cell separator, a hydrogen separation membrane, a hydrogen sensor, a solder-corrosion resisting member, etc.

摘要:
An end face polishing apparatus in which whereas a jig board mounted with a rod-like member is supported by an apparatus main body by a supporting mechanism, a polishing board mounted with a polishing member for polishing the rod-like member is supported by the apparatus main body rotatably and pivotably by a drive mechanism for polishing the rod-like member mounted to the jig board by the supporting mechanism by pressing the rod-like member to the rotating and pivoting polishing board, wherein the polishing member is mounted to the polishing board attachably thereto and detachably therefrom, further comprising an automatic interchanging device for interchanging the polishing member which is mounted to the polishing board and which has been used with the polishing member which is stored at a predetermined position and which is to be used by which the operational performance is promoted.
摘要:
The apparatus comprises an annular water-cooled metallic mold having open upper and lower ends, a core member located in the inner space of the mold to form therebetween an annular casting passage for solidifying therein the molten metal supplied in the casting passage, and a movable supporting base member adapted to initially close the lower end of the casting passage to support the molten metal therein and then to be moved downwardly apart from the lower end as the metal in the casting passage solidifies so as to permit the solidified metal to be pulled out from the casting passage for continuously producing the hollow metallic ingot. The core member comprises a heat-insulating member having a molten metal receiving vessel mounted thereon with at least one molten metal conducting passage formed therein communicating with the casting passage so as to supply the molten metal from the vessel to the casting passage, and a casting member made of graphite or a carbonic material and secured to the lower side of the heat-insulating member with the outer peripheral surface being tapered downwardly inwardly to form a casting face.
