Abstract: In a notifying device comprising a notifying unit 2 having incorporated therein a vibrator to be resonated by a drive signal fed thereto, and a signal preparing circuit 5 for feeding the drive signal to the notifying unit 2, the signal preparing circuit 5 prepares a drive signal Dv varying in frequency within a predetermined range including the resonance frequency of the vibrator of the unit 2 and feeds the signal to the notifying unit 2. The variation of frequency of the drive signal is determined in correspond relation with a variation in the resonance frequency of the vibrator due to tolerances for specifications which govern the resonance frequency. The drive signal has an alternating waveform of rectangular waves or sine waves, and the frequency thereof varies periodically from 1.37 to 2.98 Hz. The notifying device achieves a satisfactory notifying effect despite the variation of the resonance frequency of the vibrator.

Abstract: A digital circuit for driving an audio transducer that provides consistent tonal quality over a range of volume levels, without requiring a variable gain analog amplifier. A fixed amplitude ringer tone is multiplied, or amplitude modulated, by a higher frequency digital pulse train to produce a transducer driving signal. The timbre of the transducer driving signal is similar to that of the fixed amplitude ringer tone, but the volume of the sound produced by the transducer varies with the mark-space ratio of the pulse train.

Abstract: A pulse signal, having a buzzer-driving frequency, for driving a buzzer (3) is generated by a free running timer of a timer management section of a microcomputer (1). The timer management section operates independently of software processing of the microcomputer (1). A transistor (2) is turned on and off by the pulse signal having the buzzer-driving frequency. Accordingly, electricity flows through the buzzer (3). The buzzer (3) in turn, generates a sound.

Abstract: A screening machine that uses electrically controlled transducers to vibrate a separating screen. The transducers can be piezoelectric patches, discrete piezoelectric components, or electromagnetic shakers. Further, the transducers can be coupled directly to the screen or through a vibration amplifier. The transducers and/or amplifiers can be coupled to the screen at different attachment locations. One or more of the transducers can be used as sensors to provide feedback for operation control.

Abstract: An AC switch is created by switching devices to modify the output of an ultrasonic generator. The AC switch introduces a modification circuitry into and out of the output stage of the ultrasonic generator. The AC switch is placed in parallel with the modification circuitry when inserting the modification circuitry into a conduction line of the ultrasonic generator. It is placed in series when inserting the modification circuitry between two nodes of the ultrasonic generator. A control circuit is associated with the AC switch to turn on and off the ultrasonic generator, overcoming the inability of triacs to turn off power when conducting ultrasonic current. The introduction of the modification circuitry by the AC switch allows the modification of the frequency, amplitude, power, impedance and waveform of an ultrasonic generator.
