Title: High-temperature superconducting coil, high-temperature superconducting magnet using the same, and high- temperature superconducting magnet system
Inventor: ONO MICHITAKA
IPC: H01F6/06
Filed: 1999-03-26
Abstract: PROBLEM TO BE SOLVED: To make full use of the capability of a coil by disposing a high-temperature superconducting wire relative to the direction of magnetic field thereof so as to maximize the critical current. SOLUTION: A characteristic of critical current is that a critical current of a magnetic field which is parallel with a tape surface is much larger than that of a magnetic field perpendicular to the tape surface. Therefore, a high-temperature superconducting coil 1 is wound flat around a coil cross section 2, at a position having a maximum magnetic flux density in a direction A of the magnetic lines of force (a). Furthermore, the high-temperature superconducting coil 1 includes the coil section 2 having a small thickness in a diameter direction, and the coil cross section 2 has an extremely small aspect ratio in a direction B of the magnetic lines of force at a position which has maximum magnetic flux density for the coil cross section (b).  Moreover, in the high- temperature superconducting coil, magnetic flux density is larger around the surface of the coil 1, as compared with the center of the coil cross section 2. Thus, a superconducting wire around the surface of such a coil is disposed along the direction of the corresponding magnetic lines of force.

Title: Plate form denitration catalyst
Inventor: NAGAI KENICHI
IPC: B01J21/18
Filed: 1978-07-12
Abstract: PURPOSE: To make increase in size of denitration catalysts of high active plate form easy and improve strength by holding porous carrier in the core material of a wire netting in plate form by means of a binder of colloidal silica thereby containing the specified amount of SiO 2  in the catalyst material.  
     CONSTITUTION: The slurry composed of porous carrier such as active alumina, titania, etc and a binder such as colloidal silica, etc. is coated on both surfaces of a wire netting such as of carbon steel, stainless steel, etc. and is then dried, thence it is baked, if necessary, whereby the active components are carried in the resultant carrier. The colloidal silica is used as such an amount at which SiO 2  is contained at more than 8wt% in the catalyst material. As a result, the SiO 2 - N(OH) 2n  which constitutes colloidal silica causes dehydration condensation polymerization to form a three-dimensional mesh structure, causing the catalyst material to be firmly held in the wire netting. Because of this, the catalyst maintains large porosities and show high activity.
