The magnetic resonance imaging apparatus also includes a sensitive region storage device for storing respective sensitive regions for the combinations of the coil elements, a setting device for setting scan regions, a calculation device for calculating a scan volume rate indicating each of proportions of overlap regions between the scan regions and the sensitive regions to the scan regions, and a sensitivity volume rate indicating each of proportions of the overlap regions to the sensitive regions, and a selection device for selecting each combination of the coil elements used to receive the magnetic resonance signals of the subject, out of the combinations of the coil elements, based on the scan volume rate and the sensitivity volume rate.
摘要:
In a multiple view liquid crystal display, occurrence of a reverse view phenomenon and a reverse view crosstalk are suppressed. A black matrix is formed on the opposed surface of a counter substrate to a TFT substrate in a liquid crystal panel, and a parallax barrier is provided on the black matrix with a gap layer having a predetermined thickness interposed therebetween. The black matrix includes a first light blocking part disposed immediately below an opening in the parallax barrier, and a second light blocking part with a portion immediate thereabove covered by the parallax barrier. The second light blocking part includes a low refractive-index film (reverse view preventive film), having a lower refractive index than that of a liquid crystal, at the end thereof which is in contact with a pixel opening between the second light blocking part and the adjacent first light blocking part.

There are provided a composition for matte layer formation suitable for the production of a matte synthetic leather having a matte surface with a high level of jet-blackness even without the practice of embossing, raising, etc., and a release sheet for the production of a matte synthetic leather by using the composition. The composition for matte layer formation suitable for the production of a matte synthetic leather comprises a thermosetting resin and a matting agent as indispensable components. The matting agent comprises one or at least two types of organic or/and inorganic porous fine particles. The porous fine particles have a mean particle diameter in the range of 0.5 to 20 μm and a specific surface area in the range of 1 to 1000 m2/g. The release sheet is produced by using the composition.

摘要:
A method for enabling a presetter to connect connecting portions of belts having different widths, and for forming an endless connection of a flat belt with no defects such as the bend of the connecting portions. This method includes a first step of setting so that the connecting portions at both ends of the flat belt are placed on a lower mold surface of the presetter, and that, with the flat belt held from both sides by a wall part standing from the lower mold surface and a flat belt member having substantially the same compression property as the flat belt, an upper mold of the presetter is placed on the flat belt and the flat belt member, and then fixing the flat belt and the flat belt member by the presetter; and a second step of connecting the connecting portions at the both ends by pressing the presetter with the flat belt and the flat belt member fixed.
