摘要:
The preservation method of microcapsules for electrophoretic display devices according to the present invention includes preserving microcapsules for electrophoretic display devices in a water-based medium having an electric conductivity of 500 μS/cm or lower. The preservation under such conditions makes it possible to preserve microcapsules for electrophoretic display devices over a long period of time without deteriorating their electrophoretic properties. The microcapsules for electrophoretic display devices, which have been preserved by the preservation method of the present invention, can be used, as its applications, for sheets for electrophoretic display devices and electrophoretic display devices using the sheets.

摘要:
A method and apparatus for evaporating a solid organic material by sublimation using an infrared guiding heater which minimizes temperature gradients in the bulk of the organic target. The bulk is heated to a temperature below the sublimation temperature of the target. A localized area of the target is sublimated by the infrared guiding heater while regulating the temperature of the bulk. The vapor is then deposited over, and condensed on, a substrate to form a solid organic layer.

摘要:
For the high-speed data access machine, data is distributed in a plurality of hard disk drives coupled to slave processors to achieve ever-higher data reliability and maintenance. One master processor is provided with a plurality of slave processors, each of which is coupled to two hard disk drives containing the same data. A synchronous signal permits two hard disk drives to operate in synchronous rotation in half-a-turn phase difference from each other. The hard disk controller writes the same data in both hard disk drives but reads data from whichever hard disk drive requires less access time to obtain the data. A plurality of hard disk drives holding exactly the same data improves data reliability. Also, by rotating a plurality of hard disk drives in different phase, the rotational delay in data access is cut by half.
