Title: Sensorless brushless motor
Inventor: CHIKADA TAKUYA
IPC: H02P6/18
Filed: 1994-03-03
Abstract: PURPOSE:To make it possible to restart the rotation of a permanent magnet rotor without completely stopping it from sensorless brushless operation. CONSTITUTION:The title sensorless brushless motor consists of a permanent magnet rotor 1, three-phase stator winding 2, a three-phase inverter 3, a commutation control circuit 4, a rotational position detecting circuit 5 and a microcomputer 6. The microcomputer 6 outputs a drive reference signal m1 at the start of the inverter. Thereafter it outputs a rotational speed corresponding signal e4 based on a rotational position signal e3, and further an inverter drive reference signal m2. When an operation signal e8 is input immediately after the input of a stop signal, the microcomputer outputs the inverter drive reference signal. The permanent magnet rotor 1 is started by initial excitation-synchronous motor operation-sensorless brushless operation. If the permanent magnet rotor is restarted immediately after the input of a stop signal, that is done by sensorless brushless operation-stop brushless operation-sensorless brushless operation. If the permanent magnet rotor is restarted a little while after the input of a stop signal, that is done after a restart prohibition time has passed.

Title: Noise generating circuit for soft decision digital
Inventor: YAGI TOSHIHARU
IPC: H04L27/22
Filed: 1987-03-13
Abstract: PURPOSE:To make the titled circuit most suitable for large scale circuit integration by devising the titled circuit such that number of bits required to receive/ transmit a signal between a storage circuit being an externally mounted circuit and the circuit being an abject of LSI is reduced remarkably in comparison with a conventional circuit. CONSTITUTION:A timing generating circuit 3 generates a clock comprising a clock pulse number corresponding to the total bit number of decision threshold values of, e.g., 7 values in response to a start signal being an external input and gives it to an address counter 2 and a shift register 4. The counter 2 sends each decision threshold value corresponding to a ratio Eb/N0 being a ratio of an energy per one bit of transmission signal to one side noise power density N0 of a communication line by the external designation from a ROM 1 serially. Then, the register 4 fetches each decision threshold value to be outputted according to the clock and outputs each of them to other input of comparators 22-28. Thus, the address count value of the ROM 1 is enough to be 8-bit while the required bit number is to be 7X31(=217).
