Title: Driving device for digital speaker
Inventor: TANAKA YOSHIAKI
IPC: G06F17/10
Filed: 1987-06-23
Abstract: PURPOSE:To prevent the generation of a folded noise by changing a driving voltage to be impressed to a voice coil, by a negative feedback control system, which is a difference signal between an oversampled input digital signal and the position data signal of the voice coil as an error signal. CONSTITUTION:A signal demodulated by a receiving part RD is supplied to an oversampling filter OSD through a serial/parallel conversion circuit SPCa. The filter OSD expands input data X1-X16 to output data Y1-Y18, and supplies them to a digital signal processor DSP. Position data from the serial/ parallel conversion circuit SPCb is supplied to the processor DSP as well, and the position detection signal of the shifted voice coil 12 is given to the circuit SPCb. A speaker driving part DRV is driven by the output signal of the processor DSP, and at the same time, an impressed voltage to the driving part DRV is changed through a D/A converter DAC according to the difference signal between the detection signal of a voice coil position and the signal obtained by oversampling the input digital signal.

Title: Method of detecting absolute position of pointer of indicator and indicator
Inventor: KURAUSU KUROONENBERUKU
IPC: G01D5/22
Filed: 1990-06-18
Abstract: PURPOSE: To form the absolute position of a pointer type indicator without requiring any external sensor by an arrangement wherein a rotor for shifting a pointer detects a signal induced at the field forming part of a three-phase AC motor and determines the abutting angular position between the pointer and a stopper. CONSTITUTION: The control voltage of a controller 6 is formed stepwise and has a duration causing no variation in the ratio of currents flowing through coils 4, 5 between respective steps. Consequently, the rotor 2 can turn reversely when the field turns more than 180 deg. from a moment of time when a painter 33 arrives at a stopper 24. The controller 6 sets a three-phase AC motor 1 at a new angle and, after waiting for a predetermined time, checks generation of a voltage pulse using subtractors 15, 16 and sets a new angle if voltage pulse is not generated otherwise determines location of the motor 1 at the stopper 24. Consequently, an absolute reference point is formed, the pointer can be shifted to a desired position and the indicator can be operated normally.
