摘要： A method of manufacturing an Nb.sub.3 Al superconducting wire includes a step of forming a wire by a jelly-roll process, a first thermal step of heating the obtained wire at a temperature of 500.degree. to 700.degree. C. for at least 10 hours for diffusing Al in Nb while suppressing formation of Nb.sub.3 Al, and a second thermal step of heating the wire, after the first thermal step, at a temperature of 800.degree. to 1050.degree. C. for about 0.01 to 10 hours, thereby forming Nb.sub.3 Al. In the jelly-roll process, a sheet of Nb and a sheet of Al are lap-wound on a copper core. The material obtained by such lap winding is inserted in a copper pipe, and then subjected to drawing. The drawn wire is cut to obtain a plurality of segments. The plurality of segments are bundled and charged in a copper pipe, and then subjected to drawing. The resulting drawn wire is subjected to the first and second thermal steps. In this manner a superconducting material having a high critical current density under a high magnetic field is obtained.

摘要： In a dust removing system, the level of influence of dust sticking to an objective lens of an optical head is detected from either an amount of light emitted from the optical head and reflected from an optical head or from an access time. Three stages of levels with regard to the degree of influence of the dust are set in accordance with such detection value, and a different message for the removal of dust is indicated on a display unit in response to the level of the influence. When the influence is low, a dust removing mechanism is automatically rendered operative to remove the dust. At the first level at which the influence of dust is low, the optical disk in the optical disk device is discharged and cleaning of the objective lens is performed, and an indication is provided on the display unit representing that cleaning is proceeding. When the second stage is detected, the optical disk in the optical disk device is discharged, and a message is indicated on the display unit representing that cleaning of the objective lens should be performed using a cleaning disk. When the third stage is detected, a message is indicated on the display unit representing that cleaning of the objective lens should be performed by manual operation.

摘要： A cover unit includes a first cover that is movable between a cover position and an exposed position. A second cover slidably is movable in a direction perpendicular to its visible surface. A cover moving mechanism moves the second cover, wherein, when the first cover is at the cover position, the second cover is at such a height that the visible surface of the second cover is substantially coplanar with a visible surface of the first cover. When the first cover is moved from the cover position to the exposed position, the second cover is moved to such a height such that the visible surface of the second cover is moved by at least an amount that corresponds with the thickness of the first cover. When the first cover is at the exposed position, the first cover is above the visible surface of the second cover.

摘要： A plasma jet ignition plug capable of inhibiting occurrence of channeling while reducing removal of energy of plasma through a ground electrode at the time of emission of plasma. A ground electrode of a plasma jet ignition plug projects inward from a front end face of a metallic shell toward an opening end of a cavity which is open at a front end face of an insulator. A projecting distal end which forms a spark discharge gap between the same and a center electrode within a cavity is located inward, with respect to a diametral direction P orthogonal to an axis O, of a position which is located 0.5 mm radially outward from the opening end of the cavity.
