IPC: F24F9/00
Filed: 1986-12-02
Abstract: PURPOSE:To generate easily an artificial whirlwind in a free space by a method wherein a circulating stream with a negative pressure zone is formed by blowing air in a circumferential direction and its upper central part is sucked to form a core part with a negative pressure. CONSTITUTION:When air blown by an air blower 1 is ejected slantingly in the circumferential direction from a plurality of ejecting ports 2 of a circular shielding member 1 installed on a floor, the air is formed into a circulating stream with a wind direction C and at the center part a negative pressure zone D is formed. When an air blower 4 for suction installed at a ceiling, etc., is driven to rotate at the same time, a core part B with a negative pressure is formed and air ejected from the ports 2 becomes a rising swirl in being sucked to the part B, that is, forms an artificial whirlwind A which is sucked to the blower 4. Thus, the artificial whirlwind can be generated simply and easily in a free space and the capture and discharge of harmful gas or dust or the ventilation at a theater, etc., can be carried out advantageously.

IPC: H01F6/06
Filed: 1987-11-13
Abstract: PURPOSE:To prevent a short across a bobbin and a superconducting coil, by winding the superconducting coil round the bobbin made of ceramic. CONSTITUTION:A superconducting wire rod 5 of Nb3Sn and the like is wound round a bobbin 2 which is previously made of ceramics of Si2O, Al2O3 or the like, and a heat treatment is then performed at high temperatures of about 600-800 deg.C to produce a superconducting coil 1 of Nb3 Sn and the like. Now, an electrical insulator 4 of glass fiber or the like is wound round the superconducting wire rod 5 to be the superconducting coil 1. Therefore, even if the electrical insulator 4 is wrinkled or the green wire rod 5 to be the superconducting coil 1 is partially exposed in winding process, a short across the bobbin 2 and the superconducting coil 1 is effectively prevented because of the bobbin 2 being ceramic insulator, thereby working can be performed with ease. Moreover, since the ceramic material of SiO2, Al2O3 or the like withstands high temperatures above 1000 deg.C, the characteristics and strength as the electrical insulating material are not degraded even if a heat treatment is performed at higher temperatures.
