A long nip shoe calender formed of a shoe roll and a thermo roll is used in calendering, with a nip dwell time which is over 10 ms, advantageously over 20 ms. The silicon carbide layer is formed by reacting a gas mixture comprising a silicon source, a carbon source, and a dopant in the presence of an electric field. A means joins the frame to the pickup truck box. The control circuit further includes a current source circuit for supplying a driving current to a control terminal of the driving transistor in accordance with the mirror current to turn ON the driving transistor in response to an external control signal. A semiconductor die is bonded to the first conductive layer of the substrate.
