  • Patent number: 10067271
    Abstract: An optical sheet is formed by laminating, by co-extrusion molding, a first layer containing a polycarbonate resin, a second layer containing a polyamide resin, and a third layer, wherein the second layer is laminated between the first layer and the third layer, the first layer and second layer, and the second layer and third layer can each be peeled at the interface, and the outer surface of the first layer has a fine grooved structure. The optical sheet, which is provided with a plurality of layers in such a way, is capable of retaining, a sufficient amount of heat in a laminate in a mold since the entire sheet can be made thick during melt extrusion molding, and is able to improve the transferability of the fine grooved structure. In addition, the optical sheet can be made thinner by using only the peeled first layer as an optical sheet.

  • Patent number: 7610508
    Abstract: Pairs are formed from a plurality of dispersed volumes and copying between the volumes is conducted by a series of remote operations from a management server. A management server 10 instructs the generation of configuration setting files 23, 30 to host computers 20, 30 selected so as to form copy pairs. If the configuration setting files are generated by host agents 21, 31, the management server 10 instructs copy start to a host computer 20 having a primary volume. The host agent 21 generates a prescribed command via a copy pair control module 22 and causes a storage subsystem 40 to execute copying between the volumes. When copying is completed, the management server 10 acquires the newest storage configuration information from the storage subsystem 40 and updates configuration information DB12.
