A Schottky barrier silicon carbide device has a Re Schottky metal contact. The method includes automatically diverting the flexible material from a process path, placing the flexible material in contact with a rotatable drum, and measuring spectral data of the flexible material as the drum rotates. The invention furthermore relates to an installation appertaining to automation technology, and to a method for operating an electronic display apparatus. A method to attach a tape leader pin to a threader block assembly disposed in a tape drive, where that tape leader pin is disposed on one end of a magnetic tape. The placement of the apparatus within the wellbore creates an annular flow region that has a reduced tendency for premature dehydration of slurry during a gravel pack completion operation.
