Abstract: A channel estimation section 112 estimates the states of channels used for pieces of mobile station apparatus (A) and (B), using signals demodulated by radio processing sections 110, 111. A best SIR calculation section 118 calculates coefficients to be used for signal transformation by inverse matrix calculation, using the above channel estimation values by the above channel estimation section 112. A signal transformation section 119 performs linear transformation of transmission signals to the above pieces of mobile station apparatus, using the above coefficients from the above best SIR calculation section 118. Radio processing sections 120, 121 modulates each transmission signal after the above linear transformation for transmission through antennas 108, 109, respectively.

Abstract: A peanut combine having a header for lifting peanut laden vines off the ground, an auger for distributing the peanut laden vines, a series of picking or thrashing cylinders for thrashing the peanut laden vines and a series of separator cylinders for removing the peanuts from the peanut laden vines. The separator cylinders include fingers which propel the vines and which rotate at a variable flailing speed. The fingers include tips which vary in angle with respect to the path which the fingers define as they rotate on the separator cylinders.

Abstract: A synchronous motor is divulged whose direction of rotation may be chosen, comprising a rotor with permanent magnet and a stator with homopolar field, including a winding fed with an AC voltage. In response to a stopping order, a circuit controls the switch for opening the connection of the winding when the voltage is decreasing in absolute value or is cancelled out and stores the sign of its slope at the time of opening. The circuit controls the switch for closing the connection when the voltage is cancelled out or is increasing in absolute value, with a sign slope identical to, respectively opposite, the stored sign, in accordance with an order for setting in rotation in a direction identical to, respectively opposite, the preceding direction of rotation.
