Abstract: PURPOSE: A balance air motor is provided to obtain clean and permanent energy without compensation and to prevent pollution of air, water, and earth. CONSTITUTION: In a balance air motor, a rotating body is inserted in a cylinder and a joining part of the cylinder and air pockets(1',1'') formed to the rotating body is sealed up. A water tank is formed to the outside of the cylinder and an air compressor is installed to a side of the cylinder. If the compressed air of high pressure stored in the air compressor is injected into the air pockets of the rotating body through an air injection port, uniform pressure is given to eccentric plates(6',6'') formed to the lower ends of the air pockets and to upper and lower balances(2,3,4) and eccentric pressure is given to a rotating shaft(7) and thus permanent rotation of the rotating shaft is possible by the variation of the force acting on the eccentric plates. The balances are arranged with areas of the ratio of 1 to 2 to 4. The first and second balances and the third balances are concentrated on a point of force by a lever rule. The pressure to the extent of the area of the first balances is reduced on a side of the eccentric plates and is increased on a side, and the force combined with the first balances is transmitted to an eccentric rod(5) connected to the rotating shaft through the point of force and thus the rotating shaft is rotated and energy is generated. The force of the balances transmitted to the point of force is efficiently transmitted to the rotating body by a spring cock of a joining part of the eccentric rod. If the areas of the balances are larger and the pressure of the compressed air is increased, the energy is increased.

Abstract: PURPOSE: A method for allocating a channelization code in a mobile communication system, particularly for allocating a channelization code by determining the number of maximum transmission available bits of each antenna, is provided to effectively use channel resources by transmitting symbols by using an optimum channel and enhance throughput of data by sharing channelization codes among users by antennas. CONSTITUTION: A base station receives CQI(Channel Quality Information) by a transmission antenna from a terminal(S20) and selects an MCS(Modulation Code Set) transmissible to each terminal from the corresponding CQI(S21). The base station selects one antenna and then selects terminals with the large number of bits that can be transmitted through the selected antenna as many as channelization codes(S22,S23). The base station sequentially allocates the channelization codes to the selected terminals(S24). The base station checks whether the code allocation has been completed with respect to the transmission antenna(S25), and if so, the base station checks whether there remains an antenna(S26). If no antenna remains, the base station multiplexes symbols of the channelization code-allocated terminals and transmits them to each transmission antenna(S27).
