    摘要: It is an object of the present invention to provide an RF coil and an MRI apparatus capable of ensuring a wide imaging space and excellent in terms of allowing maintenance at the time of installation or failure. In order to do so, an RF coil of the present invention includes a cylindrical outer conductor and a plurality of rung conductors disposed inside the outer conductor along a circumferential direction of the outer conductor. In addition, each of the plurality of rung conductors is electrically connected to the outer conductor through a capacitor so as to form an electrical loop. The outer conductor is divided into a plurality of portions in the circumferential direction and is characterized in that the numbers of rung conductors disposed in at least two divided portions are different. In addition, an MRI apparatus of the present invention includes such an RF coil.

    摘要: When an optical element is produced using a liquid crystal film having no supporting substrate film for the purpose of decreasing the weight, the liquid crystal film layer may often pose problems of fine wrinkly deformation of and cracking in a caused by strain occurring during a manufacturing/processing step. The present invention intends to provide an elliptical polarizer having a thinned optical anisotropic element which is free from such deformation and cracking. The elliptical polarizer of the present invention comprises at least a polarizer and an optical anisotropic element wherein said optical anisotropic element comprises a liquid crystalline substance layer with a fixed liquid crystal orientation, a tacky adhesive/adhesive layer, and a stress blocking layer.
