Abstract: In a stepping motor control method using an encoder, a timer means is provided, and an excessive advance of a phase during low rotation is restricted to attain a high speed without compromising stability during low rotation by driving the motor in such a manner that a pre-reversal state is recovered a predetermined time after a voltage reversal and a post-reversal state is recovered after one cycle of an angle detecting means. A device is provided which controls a speed by a pulse generator generating pulses at predetermined intervals, which detects a sudden drop in speed from a predetermined time elapsed from the last pulse, and which detects, when a speed is to be recovered, an abnormal drop in motor rotation independent of the motor rotation speed by changing a threshold value of an elapsed time according to an actual speed, a speed command value and an acceleration command value.

Abstract: The stepping motor controller of the present invention includes: a stepping motor including a rotor and an excitation coil; a drive section for supplying multiple-stage drive current to the excitation coil in response to an input command value, thereby enabling a micro step drive; a control section for controlling the stepping motor by varying the command value to be provided for the drive section; and a position detection control section for generating a detection signal in accordance with a rotation position of the rotor.

Abstract: An FM multiplex broadcasting and receiving system has an FM multiplex broadcast apparatus and an FM multiplex receiving apparatus. The FM multiplex broadcast apparatus has a reproducing device for reproducing, from a recording medium, an audio signal and character data associated with the audio signal recorded in the recording medium. The FM multiplex broadcast apparatus also includes a multiplex device and a frequency modulation device. The multiplex device multiplexes the audio signal with additional information such as the character data to generate a multiplex signal. The frequency modulation device frequency modulates a carrier with the multiplex signal to provide an FM multiplex broadcasting signal. The FM multiplexing receiving apparatus has a frequency demodulating device for frequency demodulating the FM multiplex broadcast signal to provide an audio signal and an additional information data signal, a displaying device displaying the additional information data signal.
