Title: Driving device for brushless motor, and motor using the same
Inventor: KIYOMA TOSHIAKI
IPC: H02P6/17
Filed: 2002-05-31
Abstract: <P>PROBLEM TO BE SOLVED: To provide a driving device for brushless motor wherein a power consumption is reduced when a motor is started and high rotational accuracy is attained by PWM frequency driving during steady-state rotation, and also to provide a motor using the driving device.  <P>SOLUTION: The driving device for brushless motor comprises a frequency switching means 60 and a pulse width modulating means 70. The frequency switching means 60 switches the carrier frequency of the pulse width modulating means 70 when the motor is started and in steady-state rotation after start-up. The carrier frequency at start of the motor is set to a value lower than that during steady-state rotation. Thus, power loss which is produced by PWM chopping when the motor is started is reduced. In addition, during steady-state rotation, high rotational accuracy is attained by driving at a sufficiently high PWM frequency.  <P>COPYRIGHT: (C)2004,JPO

Title: Method for supporting relief channel in communication system
Inventor: SAYEEDI SHAHAB M
IPC: H04W36/08
Filed: 2002-06-12
Abstract: PROBLEM TO BE SOLVED: To provide a signal transmission scheme for reducing the omission of a call in a radio mobile network. SOLUTION: To attempt to recover a voice call which may drop off, a relief channel function supports use of previously allocated radio resources of an adjacent BS. Upon detecting loss of frames in a sequential direction from the network, an MS puts its transmitter into a disabling state. Upon receiving transmission loss from the MS once, the transmitting source BS executes addition of a soft hand-off to a relief cell in an adjacent BS, thereby attempting re-establishment of a communication with the MS. The adjacent BS is selected on the basis of a list of adjacent stations of the MS, the latest report of an expansion pilot strength measurement message(EPSMM) or, in another case, another factor.
