Abstract: PURPOSE:To settle an external capacitor with only one and to reduce the number of feedback terminals by providing a differential amplifier in which a pair of outputs in the final stage of an intermediate frequency amplifier is set to be base inputs, and a current mirror circuit, etc. CONSTITUTION:The collector outputs of a pair of transistors TRQ3 and Q4 constituting the final stage of the intermediate frequency amplifier stage are impressed on the bases of TRQ7 and Q8 constituting the differential amplifier circuit, and a current I1 flows in the collector of TRQ7, and a current I2 in the collector of TRQ8. Respective collector currents of TRQ9 and Q10 constituting the current mirror circuit are equal, and the collector current of TRQ9 goes to I2. Consequently, the current of I1-I2 flows in a terminal T4 provided for the connection of both collectors of TRQ7 and Q9. The current is obtained by current-converting the output voltage of the intermediate frequency output level, and it charges an external capacitor C3. Then, the terminal voltage of the capacitor C3 is fed back by the base of TRQ1 in the initial stage of the intermediate frequency amplifier stage through a resistance R9. Thus, only one external capacitor is needed and the number of the feedback terminals can be reduced.

Filed: 1987-01-13
Abstract: PURPOSE:To improve a converting efficiency by providing a carrier wave oscillator and a modulator to modulate a carrier wave by a sound signal, and an ultrasonic wave generator, driven by the output of the modulator, and using an intermittent wave or a waveform that the plural waves with a different amplitude are combined, as the waveform of a carrier wave. CONSTITUTION:A speaker 2 is constructed by arraying 1000 number of ultrasonic oscillators, the center frequency of which is 40 kHz, in a bee hive shape, and connecting all of them in parallel. At first, the carrier wave, shown in a figure, is generated by an optional waveform generator 5a, and is modulated by the sound signal, and is inputted to the speaker 2 through a power amplifier 6. In the figure, when a sound wave is emitted, because a voltage of 2<1/2> times of a continuous wave is impressed, the primary wave sound pressure level is 3 dB higher than the continuous wave. Because a secondary wave sound pressure is proportional to the square of the primary wave sound pressure, a secondary wave sound pressure level is 6 dB higher. On the other hand, when the sound wave is not emitted at all, the secondary wave is not generated as a matter of course, but it comes 3 dB higher on an average, compared with the time of the continuous wave. Namely, by driving by the waveform shown in the figure, the converting efficiency from electricity to sound is doubled.

IPC: H02M7/48
Filed: 1994-01-24
Abstract: PURPOSE:To detect the amount of current supplied to a polyphase AC motor by using one current detector regardless of kinds of switching elements used for an inverter. CONSTITUTION:Constant-current regulation is carried out for a three phase AC motor 1 by means of a three phase inverter 7 and an inverter control circuit 8.

Output detected by the detector 10 is amplified by an amplifier circuit 20 before full-wave rectification is performed by a current-calculating device 11 so as to obtain an absolute value. The output which has been full-wave-rectified, corresponds to the amount of current supplied to the three phase AC motor 1. The amount of current supplied to the three phase AC motor, therefore, can be detected by the output of the current calculating device 11.
