    Abstract: In a resonating assembly, a beam having a pickup thereon is positioned proximate to a magnet which passes across the pick up at a predetermined frequency. The passage of the magnet across the pick up establishes an alternating magnetic field that in turn causes the beam and pick up to vibrate. A blade is mounted on the beam and vibrates therewith so that when the blade is brought into engagement with a layer of sheet type work material the vibratory amplitude of the blade causes the blade to cut through the material as it is moved in engagement therewith.

    Abstract: This invention deals with a portable terminal that reduces extraneous tones in a portable terminal in which is mounted an electromagnetic induction actuator that produces voice signals, a buzzer signal or a low frequency vibration. By short-circuiting the terminal fittings of the electromagnetic induction actuator or by connecting them electrically to amplifiers or to a signal generator that produces a constant voltage signal or a constant-frequency signal, the extraneous tone produced by vibration of the mechanical vibration system of the actuator is reduced.

    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: An electro-mechanical-audio converter and an electro-mechanical-audio converting device using the same employed in mobile terminals such as mobile phones for generating paging vibration which realizes stable vibration function. The electro-mechanical-audio converter includes a housing (1a), movable part (2), forming a magnetic circuit, mounted on an opening of the housing (1a) through a suspension (3); and a detection coil (11) disposed near the movable part (2) for generating excitation voltage by vibration of the movable part (2). Strong vibration of the movable part (2) during resonance is detected by the detection coil (11) as an excitation voltage, and fed back. Accordingly, the electro-mechanical-audio converter and electro-mechanical-audio converting device using the same having an extremely stable vibration function, even when resonance frequency changes due to environmental changes such as ambient temperature, is made feasible.

    Abstract: The remote inspection of seam welds in reactor vessels is improved through the utilization of a pulser network which is inductively isolated from the transducer circuit to which it applies an excitation signal. Through the utilization of a step-up transformer, the pulser network may perform in conjunction with linear d.c. power supplies of lower voltage rating. The inductive coupling between circuits also serves to provide for the positive commutation off of switching devices such as SCRs employed for excitation signal triggering. To avoid ground path induced noise, a different ground path is employed for the pulser network as for the transducer circuit. The transducer circuit ground path is that associated with a manipulator and, for example, a reactor vessel itself. Thus, the transducers employed may come in contact with the surface of the vessel being inspected. In similar fashion, an inductive coupling is provided between the transducer circuit and a pre-amplfying receiver circuit. This same inductive coupling may be employed to enhance the impedance match between the FET-based amplification stage and the impedance defining components of the transducer circuit.

    Abstract: A device for driving a piezoelectric vibrator is comprised of an AC power supply for supplying electric power to a piezoelectric vibrator for vibration thereof, a detecting device for detecting current supplied to the piezoelectric vibrator, and a driving circuit interposed between the AC power supply and the piezoelectric vibrator so as to decrease the electric power being supplied to the piezoelectric vibrator as the current flowing therethrough increases. This structure brings a decrease in electric power being supplied to the piezoelectric vibrator when current flowing therethrough is increased during resonance of the piezoelectric vibrator, thereby enabling the restriction or regulation of the expansion and contraction of the piezoelectric vibrator while maintaining resonance thereof.

    Abstract: An amplitude control unit for an ultrasonic machine comprises a load detector for detecting the load applied to the tip of a tool during ultrasonic machining on the work, a load/amplitude conversion circuit for converting the load output detected by the load detector into an amplitude conversion value appropriate for the load at the tip of the tool, an amplitude addition circuit for receiving the amplitude conversion value generated by the load/amplitude conversion circuit and for adding it to a predetermined amplitude value at no load. The vibration of the piezoelectric transducer is changed to correspond to the load applied to the work by sending the new amplitude value generated by the amplitude addition circuit to the high frequency oscillator.
