  • Publication number: 20050013661
    Abstract: An electromagnetic absorber formed of conductive fiber or the like, such as carbon fiber having an overall length corresponding to the wavelength of electromagnetic waves to be absorbed, is mixed into a base material to form an electromagnetic wave-absorbing pavement material. The electromagnetic wave-absorbing pavement material is used to form a pavement having an electromagnetic wave absorbing course. Further, an electromagnetic wave reflecting course is disposed under the electromagnetic wave absorbing course, and the electric length of the electromagnetic wave reflecting course is set to a predetermined value in relation to the dielectric constant so that electromagnetic waves reflecting off the surface of the electromagnetic wave absorbing course and electromagnetic waves reflecting off the electromagnetic wave reflecting course have opposite phases and thereby cancel each other out, whereby the electromagnetic waves are absorbed well.

  • Publication number: 20040260696
    Abstract: An object of the present invention is to provide a job management method for making it possible to reuse jobs in an ETL process. In the job management method, a job information table is accessed, jobs having table attributes and data field attributes matching between the respective jobs are retrieved, and, for each retrieved job, matching degrees of the data field attribute of “other jobs” in which the matching has been confirmed are calculated. Then, the “other jobs” in which the calculated matching degrees is equal to or more than a predetermined level are identified, and the identified “other jobs” are outputted to an output interface.
