摘要:
Compositions of high lubrication and light coloration are disclosed in which a selected class of resins and rubbers is blended with a specified cured polybutadiene product. The cured product results from crosslinking more than 10% of vinyl bonds in a butadiene polymer having a vinyl bond content of not less 20% by mol in terms of its monomer unit. Also disclosed are solid lubricants comprising a specified fluorinated cured polybutadiene and compositions containing the solid lubricant.

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.

An optical film comprising a resin and birefringent needle-shaped particles, the resin being added with the birefringent needle-shaped particles and being stretched to form the optical film (hereafter designated as Optical Film A), wherein (i) the resin exhibits a positive birefringence along a stretching direction when stretched; (ii) the birefringent needle-shaped particle exhibits a negative birefringence along the stretching direction of the optical film; and (iii) the optical film satisfies the following relationships: ny(a)
摘要:
Fine particles having a thin cholesteric liquid crystal film superior in visibility for a selectively reflected light are provided. Non-liquid crystalline fine particles for nucleus are dispersed in a cholesteric liquid crystal solution, then the solvent used is removed, followed by heat-treatment and cooling, to afford fine particles coated with a thin cholesteric liquid crystal film.
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.
摘要:
An HA (High Availability) scenario compiler is arranged in one of a group of computers constituting a multi-computer system, or a computer independent of the system. An HA scenerio abstractly and integrally describing the configuration and control contents of the system is read and decomposed into separate processes for the respective computers. An HA script set in a form directly executable by the respective computers is generated from the HA scenario. HA script for each one of the computers are respectively distributed to specific directories of the computers by an HA script distribution mechanism.
