Granted: 2003-09-09
Abstract: A signal is prevented from being transmitted from a mobile station to a base station with excessive transmission power for thereby increasing an uplink capacity. The base station compares the reception quality of the signal transmitted from the mobile station with target reception quality, and determines an increment for transmission power of the base station based on a compared result. The base station adds the increment to the transmission power of the base station based on a second control command transmitted from the mobile station, and transmits a first control command for controlling transmission power of the mobile station with the transmission power to which the increment has been added. If the reception quality of the signal transmitted from the mobile station becomes greater than the target reception quality, then the increment for the transmission power is increased. If the reception quality of the signal transmitted from the mobile station becomes smaller than the target reception quality, then the increment for the transmission power is reduced.

Abstract: A process for the extraction of copper from a sulphide ore or concentrate comprises the steps of subjecting the ore or concentrate to pressure oxidation in the presence of oxygen and an acidic solution containing halide and sulphate ions to obtain a resulting pressure oxidation slurry. The slurry is subjected to a liquid/solid separation step to obtain a resulting pressure oxidation filtrate and a solid residue containing an insoluble basic metal sulphate salt. The basic metal sulphate salt is leached in a second leaching with an acidic sulphate solution to dissolve the basic metal salt to produce a leach liquor containing a metal sulphate, e.g. copper sulphate, in solution and a resulting solid residue. The leach liquor is separated from the solid residue and subjected to a solvent extraction process to produce metal concentrate solution and a metal depleted raffinate. At least a portion of the raffinate is recycled to the pressure oxidation.

Title: Signal production circuit and display device using the same
Inventor: NAKAMURA EIJI
IPC: G09G3/30
Filed: 2000-10-11
Granted: 2003-06-03
Abstract: A serial-to-parallel converter circuit is constructed of a plurality of D flip-flops receiving, as a clock signal, data in a single signal of serial data stored in a ROM. Each D flip-flop transmits "high" data to a next stage through a latch operation every time a piece of the data is read from the ROM. The plurality of D flip-flops converts the signal of serial data to parallel data by producing output signals as control signals. According to this arrangement, a signal production circuit and a display device incorporating it become available which allow for a reduction in the capacity, cost, and dimensions of the storage means, and also in the wiring and substrate areas required around the storage means, through more efficient use of the data stored in the storage means.

Title: Electric drive system for planer mill infeed and outfeed rolls
Inventor: KYRSTEIN JOHN PER
IPC: B65G23/22
Filed: 1998-02-20
Granted: 2002-08-13
Abstract: A method and apparatus for converting a conventional mechanical or hydraulic system for driving the infeed and outfeed rolls of a planer mill or a similar conveyor to variable frequency electric power. The method involves disconnecting the roller shafts from pre-existing mechanical and hydraulic drive components housed within the conveyor gearbox or other support frame. The electric motors are mounted at fixed positions on a panel rigidly connected to the gearbox or other support frame at a location spaced-apart from the roller shafts. Each motor is coupled to a corresponding roller shaft by means of a connector drive shaft having universal joint couplers at each end thereof. This arrangement permits displacement of the roller shafts during normal operation of the conveyor without transferring torque forces to the electric motors. The speed of each motor and hence each roller may be independently controlled by a frequency inverter which is operable by remote control.
