Patent JP-2004504149-A (JP)
IPC: B21C47/24
Filed: 2001-07-11
Abstract: The invention relates to a device for receiving, transporting onwards and unwinding coils of rolled strip (WB) which are successively transported to the device from a strip rolling mill or a rolled strip storage unit. The device consists of a carousel-type support (KT) which can be driven in rotation about a vertical axis (VA) and on which a pair of radially projecting, rotationally mounted support mandrels (TD) with axial locking elements are located, these support mandrels being angularly offset from each other about 190°. The carousel support (KT) pivots the support mandrels out of a receiving position (A) for the coils of rolled strip (WB), into an unwinding position (C), about a pivot angle of 180°. The carousel support also has at least two other support mandrels (TD II and TD IV) which are offset from the two aforementioned support mandrels (TD I and TD III) by 90°, respectively. Other processing positions (B and D) for removing the coil binding strip and marking or applying the coil binding strip are provided between the receiving position (A) and the unwinding position (C) and between the unwinding position (C) and the receiving position (A) of the support mandrels (TD I, TD II, TD III, TD IV), angularly offset about 90°, respectively.

IPC: H04B1/04
Filed: 2000-11-03
Abstract: Techniques for adjusting the bias current of an active circuit in a transmitter based on the signal gain of the transmitter. The bias current affects various performances including linearity, noise figure, frequency response, and others. The amount of bias current that provides the required level of performance is dependent on the power level, which can be inferred from the gain control signals used to control the variable gain elements in the transmit signal path. Initially, at least one gain control signal for at least one variable gain element in the transmit signal path is received, with each gain control signal being indicative of an amplitude of a signal to be operated on by the active circuit. The bias current of the active circuit is then adjusted in accordance with the received gain control signal(s). To ensure proper circuit performance, the bias current can be limited to within a range defined by an upper value Imax and a lower value Imin can be set to a percentage of Imax. Imax and Imin can be generated by programmable current sources, and can also be compensated for temperature and power supply variations.
