A necktie button for a necktie provided with a front button part which defines the button shape and a rear part which is able to be joined to the front button part for holding the necktie between these two parts. This current causes the generation of an electromagnetic field that induces on a control probe irradiated by the electromagnetic field, an induced voltage of markedly constant amplitude during the ramp-like linear growth period of the current. This is followed by providing a viscoelastic fluid into the formation, where the viscoelastic fluid is broken by hydrocarbon, thereby remaining and viscosifying primarily in the water producing layers. A fast collimation means positioned behind the at least one laser-diode bar in a beam-propagation direction perpendicular to the slow-axis direction and the fast-axis direction. A memory controller transmits bank select signals over bank select signal lines and encoded chip select signals on the command and address bus which are used to select an individual memory device or group of memory devices in a bank for an operation.
