A dilute copper alloy material includes, based on a total mass of the dilute copper alloy material, 2 to 12 mass ppm of sulfur, 2 to 30 mass ppm of oxygen, 4 to 55 mass ppm of titanium, and a balance of pure copper and inevitable impurity. A part of the sulfur and the titanium forms a compound or an aggregate of TiO, TiO2, TiS or Ti—O—S, and an other part of the sulfur and the titanium forms a solid solution. TiO, TiO2, TiS and Ti—O—S distributed in a crystal grain of the dilute copper alloy material are not more than 200 nm, not more than 1000 nm, not more than 200 nm and not more than 300 nm, respectively, in particle size thereof, and not less than 90% of particles distributed in a crystal grain of the dilute copper alloy material are 500 nm or less in particle size.

摘要:
Disclosed is a superconductor which has an aluminum area at the center of the cross section of the superconductor and a copper-covered multifilamentary NbTi composite conductor at the periphery parts of the cross section formed around the aluminum area, wherein the cross-sectional area ratio of (Cu+Al)/NbTi is in the range of 0.5 to 3.0 and the cross-sectional area ratio of Al/Cu is in the range of 0.05 to 0.5.. The superconductor is provided by a method comprising a first step of providing a superconductor-copper composite hollow body in which copper films are applied around the superconductors, a second step of area reducing the composite hollow body, a third step of heat treating the body, a fourth step of inserting an aluminum body into the hollow of the hollow body, a fifth step of subjecting the body to working such as drawing, a sixth step of subjecting the body to working such as twisting, forming or the like, with an additional area reduction being carried out, if necessary, subsequent to the third step. A superconducting coil is made using the superconductor, and the coil is used for a magnetically levitated vehicle or a nuclear magnetic resonance apparatus.
摘要:
The present invention provides an image forming device comprising a first roller mechanism for sending out printing paper from a paper feed tray accommodating the printing paper therein, a second roller mechanism for transporting the printing paper to a printing start position where formation of an image on the paper is started, and a power supply mechanism for giving power to the first roller mechanism and the second roller mechanism. The device transports the printing paper at a first transport speed from an accommodated position inside the feed tray to a first position where the paper is transportable by the second roller mechanism, by driving the first roller mechanism, discontinues the driving of the first roller mechanism by the power supply mechanism upon the printing paper reaching the first position, transports the printing paper from the first position to a second position where the paper is taken out of the feed tray at a second transport speed lower than the first transport speed by driving the second roller mechanism, and transports the printing paper from the second position to the printing start position at a third transport speed higher than the second transport speed by driving the second roller mechanism.
摘要:
A superconductor which includes a housing of a highly pure copper having a slot therein for accommodating a plurality of monolithic superconductor members and a reinforcing member. A highly pure aluminum lid or cover is adapted to be disposed in an opening of the slot, with outer surfaces of the lid or cover having arranged thereon highly pure copper. The lid or cover, the monolithic superconductor members, the reinforcing member, and the housing are integrated and bonded together by a bonding material such as, for example, solder.
摘要:
The present invention provides an image forming apparatus for forming an image on printing paper by rolling up the printing paper around a cylindrical or column-shaped member without any fixture, that can measure with a high accuracy the length of the printing paper during transport thereof. The image forming apparatus of the present invention forms an image on printing paper in a state in which the printing paper is rolled up around an outer circumferential surface of a cylindrical or column-shaped member, and includes a sensor for detecting a front end or a rear end of the printing paper on the outer circumferential surface and a controller for calculating a length of the printing paper. The sensor, after having detected the rear end with the printing paper completely rolled up around the member, detects the front end along with rotation of the member. The controller calculates the length of the printing paper based on an operation amount of the member or a mechanism associated with driving of the member during a period from a detection of the rear end by the sensor until a detection of the front end.
