Title: Levitated running electric rolling stock
Inventor: YAMABE HIROSHI
IPC: B60L13/10
Filed: 1998-05-19
Abstract: PROBLEM TO BE SOLVED: To permit the line of magnetic flux of a magnet to play the role of gear for running on an aluminum plate and thereby allow an electric rolling stock to run with a magnet. SOLUTION: A strong magnet 1 and a conductor 4 are used. The magnet is attached to a motor shaft so as to rotate, while the conductor 4 is laid between rails. Since a cylindrical magnet formed of N and S poles arranged in the shape of a sector so as to equally divide a circle is rotated at high speed, electric field is generated between aluminum of conductor 4, and magnet and a current is generated on the aluminum plate 4. This current repulses for the magnetic flux lines of the magnet, and thereby an electric rolling stock is levitated. In addition, the lines of magnetic flux on the gear generated, depending on arrangement of magnet results in a propelling force of the electric rolling stock.

Title: Ceramic roll
Inventor: KAWAHIGASHI TAMITO
IPC: B21B27/03
Filed: 1995-07-12
Abstract: PROBLEM TO BE SOLVED: To withstand rolling under a heavy load condition and to enable to reuse even when the exfoliation is caused in the surface part or the like by composing a roll of the outer layer of the barrel part which is formed from excellent ceramic materials consisting of highly pure powder whose defects of foreign matters and pores are reduced and a shaft formed from the excellent ceramic materials having high strength and high toughness. SOLUTION: Since a ceramic roll having two-layer structure is enabled, even when exfoliation and crack caused by rolling accident or the like are generated, the ceramic shaft 2 is reused by changing the outer layer 1 of the barrel part. Besides, by using ceramics having high strength and high toughness for the shaft 2, the roll itself has high strength and high toughness and the roll withstands rolling under the heavy load condition. Since the ceramics of highly pure material powder are used for the outer layer 1 of the barrel part, surface defects are reduced. Moreover, the use of the highly pure material powder is reduced and, by sintering a sleeve 1 through the worked shaft 2, a sintered compact having small allowance for machining and small bend is obtained.
