Title: Audio decoder
Inventor: FUJII YUKIO
IPC: G10L19/02
Filed: 1998-08-10
Abstract: PROBLEM TO BE SOLVED: To decode the digital speech signal of plural different formats by suppressing the increase of the capacity of internal RAM and of an operation clock frequency. SOLUTION: Two digital signal processors(DSP) 8 and 3 are used and each of them shares the load of audio decoding processing. DSP 8 decode-processes an audio BS(bit stream) from an input terminal 1 by a frame unit and generates frequency coefficient data to write into an external memory 11. DSP 3 reads frequency efficient data of this frame unit and decode-processes it to be PCM (pulse encoding) sample data. This PCM sample data is supplied for a D/A converter 6 through a PCM output I/F circuit 5 and converted to an analog speech signal. In a case when DSP 8 cannot decode-process one frame of audio BS in one frame period because of overloading, a deadline control circuit 12 makes DSP 8 to process the remainder in the next period and makes DSP 3 interpolate-operate in this frame period.

Abstract: PURPOSE:To reduce fluctuation of rotation and to reduce the size of a motor by forming different poles alternately on the inner circumferential face of a permanent magnet and inclining the border between adjoining poles from the axial direction. CONSTITUTION:Hall elements H1-H3 are arranged at the outer circumferential side of salient poles P1-P3 and detect the strength of magnetic field of a permanent magnet 16 corresponding to the rotary position of a rotor 3.

When the skew angle is set to 45 deg., stable state and unstable state are balanced at 2:2 and sufficient skew effect is achieved. By such arrangement, cogging is reduced in rotary driving and rotary state having low vibration can be maintained.
