  • Publication number: 20060271815
    Abstract: When a public line is used for a remote copy function of storage in a disaster recovery (DR) system, the online performance is degraded due to the increase and decrease of the line utilization rate. Therefore, it is desired to change the remote copy function depending on the line utilization rate. Also, there is the possibility of data loss if disaster occurs during the copy between storage devices. Therefore, it is desired to perform the processing to detect the data status immediately before the occurrence of the disaster. By switching the synchronous transmission and the asynchronous transmission in accordance with the increase and decrease of the response time of the remote copy function between storage devices, the online performance of the primary site can be maintained without being influenced by the line utilization rate, and the data loss can be detected based on the used remote copy function.

  • Patent number: 7095009
    Abstract: A detector system, filter therefor, and method of making same is disclosed. The filter includes an interference element having a reflection band disposed primarily in the near infrared, and having a high transmission over most of the visible region. The filter also includes an absorptive element that absorbs light non-uniformly over the visible region.

  • Publication number: 20060147729
    Abstract: An optical display, and method for forming an optical display, having improved antireflection properties and durability is formed by applying a transferable antireflection material to an optical substrate through the use of an in-mold or heat press technique or alternatively by an ultraviolet exposure technique. The transferable antireflection material is formed prior to application to the substrate and has at least a low refractive index layer and a high refractive index layer coupled to a release film. The low index reflection layer is preferably a silicon-modified fluoropolymer material having good durability, low refractivity, and appropriate adhesion to the release layer and subsequently applied high index refraction layer. The optical display is then coupled to a housing of an article for use.

  • Publication number: 20060147724
    Abstract: A silicone-modified fluoropolymer is formed by first dissolving a fluoropolymer in an organic solvent, the fluoropolymer having at least one monomer of vinylidene fluoride coupled to a hexafluoropropylene monomer unit, and subsequently reacting the mixture with an amino silane coupling agent to form an aminosilane-modified fluoropolymer. The aminosilane fluoropolymer is subsequently heated and partially condensed with an oligomer of a silane compound including alkoxy silane. The resultant composition is suitable for use as a low refractive index layer in an antireflection coating on an optical substrate.

  • Publication number: 20060058433
    Abstract: A method for prevention of increase in particles in copolymer for semiconductor resist, which comprises passing, through a filter containing a resin having an amino group and/or an amide bond, a copolymer solution for semiconductor resist which contains a copolymer for semiconductor resist having a polar group-containing recurring unit and an alicyclic structure-containing recurring unit and which contains no ionic additive. With the method, there can be obtained a copolymer for semiconductor resist, which can be suitably used in a resist film used for formation of a fine pattern in semiconductor production and which is very low in formation of particles during storage and accordingly generates substantially no defect after development.

  • Publication number: 20040237088
    Abstract: A JOB distribution control method for a plurality of Computer Service Centers connected via a network represented by the Grid is provided. When a JOB request occurs in a first Computer Service Center, a current average JOB request interval of the first Computer Service Center is calculated. The necessary number of servers for achieving a predetermined JOB response time is calculated from a predetermined standard JOB request interval, a predetermined standard JOB execution time of servers, and the calculated current average JOB request interval. Only when the number of the servers in the first Computer Service Center is over the calculated necessary number, the JOB request is transmitted to a remote second Computer Service Center.

  • Patent number: 6228543
    Abstract: A plasticizer-containing layer can be used in a thermal transfer element to facilitate transfer to a receptor for the formation of a variety of articles. In one method, a receptor is brought into contact with a thermal transfer element that includes a transfer unit having at least one layer with a binder composition and a plasticizer. A portion of the transfer unit is thermally transferred to the receptor. This thermal transfer can be accomplished using, for example, a thermal print head or radiative (e.g., light or laser) thermal transfer. After transfer, the binder composition and the plasticizer (in the portion of the transfer unit that is transferred to the receptor) are reactively coupled.
