<p>PURPOSE:To transfer an article in a completely noncontact condition by forming or installing a superconducting material layer on the back side part of the article and conveying this article in a floating condition in a magnetic field. CONSTITUTION:A superconducting material of a composite oxide is coated on the back side of an article 1 in the state of paste and sintered to form a superconducting material layer 2. Permanent magnets 3 are arranged in a sheet form along a conveying passage and the article 1 is inserted into the magnetic field thereof and floated up. And, air is obliquely jetted out of air jet-out ports 4 which are obliquely formed on the sheet-like permanent magnets 3, and the article 1 is transferred along the oblique direction of the jetted air while being kept floated up. Hence, the article 1 is evenly floated up due to sufficient buoyancy and conveyed, thereby, preventing the pollution and scratch of the article.</p> |
