Abstract: PURPOSE:To provide a magnetic friction roller type power transmission mechanism allowing positive transmission to be obtained in the oilless state and easy in maintenance because of not having complicated elastic pressure contact mechanism between rollers so as to be made compact and prevented from the easy wear of the rollers and generating sliding between the rollers in the case of overload being applied so as to be prevented from being damaged or excessively burdened. CONSTITUTION:A pair of iron rings 6, 7 are rigidly secured being respectively brought close to the side faces of the N-pole side and S-pole side of a permanent magnet ring 5, and the edges of the iron rings 6, 7 are protruded from the end of the permanent magnet ring 5, along the N-pole side face and the S-pole side face to form a magnetic friction wheel 1. The magnetic friction wheel 1 is rotatably supported, and an iron roller 3 is rotatably supported in such a way as to be in contact with the edges of the iron rings 6, 7. Rotational power is mutually transmitted by the magnetic frictional force between the magnetic friction wheel 1 and the iron roller 3.

Title: Rf coil of magnetic resonance imaging device
Inventor: MORI KAZUO
IPC: G01R33/34
Filed: 1998-03-11
Abstract: PROBLEM TO BE SOLVED: To provide an RF coil of a magnetic resonance imaging device in which a high S/N sensitivity region to MR signals can be enlarged transversely to the direction of travel of a center conductor and the degree of sensitivity decrease in the direction of the depth of a subject does not become steep. SOLUTION: This RF coil has a center conductor 10 having a predetermined width in the direction of (y)-axis. The arrow I indicates the direction of a current and the arrow S the direction of a sensitivity magnetic field. When a static magnetic field is directed in (z)-axis, MR signals are fluctuations of magnetic forces within the xy plane. In this case, if the (y)-direction components of the magnetic forces are great, i.e., if the magnetic forces in the (y)-direction are dense, this means that the sensitivity to the MR signals is high. The center conductor 10 of the RF coil has a high sensitivity region spread in (y)-direction, thus making it possible to enhance the sensitivity to the MR signals.
