IPC: C02F11/12
Filed: 1999-12-03
Abstract: The high intracellular water content contained within the cell walls of the bacterial cells of a dewatered biosludge is reduced by removing the intracellular water in a denaturing operation. This operation comprises heating the biosludge at a temperature sufficient to weaken the bacterial cell walls. The weakened cell walls are then exposed to a reduced pressure sufficient to form vapor within the cell and to thus rupture the weakened cell walls and thereby release the intracellular water in the form of a hot aqueous vapor and/or released intracellular water. The water-reduced concentrated biosludge can then serve as a fuel source in a partial oxidation reaction for the production of synthesis gas.

Abstract: A method and system for the transmission, reception, and processing of 4-level and 8-level signaling symbols is provided. An inventive modulator is provided for modulating 4-level signaling symbols using an 8-level modulator. Further, this inventive modulator is able to produce 4-level modulation when modulating 4-level signaling symbols using an 8-level modulator, where the 4-level modulation represents the 4-level symbol sequence modulated. Further, a constrained/unconstrained demodulator is provided which is able to demodulate both 4-level signaling symbols and 8-level signaling symbols. The inventive demodulator accomplishes this by limiting the number of new symbol hypotheses and path histories to 4 when working with 4-level signaling symbols, and setting the number of new symbol hypotheses and path histories to 8 when working with 8-level signaling symbols. Additionally, an error correction decoder is provided which is also able to decode a demodulated signal which contains both 4-level and 8-level signaling symbols. The inventive error correction decoder accomplishes this by utilizing an interleaver that only places bits in the 2-bit positions of the 3-PSK soft values that correspond to the 2-bits of QPSK to decode 4-level signalling symbols, and utilizing an interleaver that places bits in all three of the possible bit positions of a symbol to decode 8-level signalling symbols.

Inventor: OKAI SHOTA
IPC: H02P6/17
Filed: 2001-01-26
Abstract: PROBLEM TO BE SOLVED: To brake a DC motor having a large holding force. SOLUTION: Each time the DC motor 2 is rotated at a predetermined angle, Hall elements 12a to 12c generate pulse signals. When a control circuit 10 decides that the speed of the motor 2 has decelerated from a predetermined speed, based on the pulse signal in a state in which a stop command is given to the motor 2, the circuit 10 sends a servo command signal. At a servo command signal generating time, the circuit 10 sends a rotation direction command signal to a reverse rotation direction to the rotating direction of the motor 2, based on the pulse signal. The circuit 10 generates a brake force command signal, corresponding to an actual rotational speed of the motor 2, after the servo command signal and holds the signal.  A driver 8 makes the motor 2 rotate by a brake force, in response to the brake force command signal in the direction for designating the rotation direction command signal.
