摘要： A threshold value adjustment circuit for adjusting a predetermined threshold value is provided in a stage followed by a protection circuit which starts protection operation when a load current flowing into an MOSFET exceeds the threshold value. A voltage proportional to a drain current and generated between the opposite ends of a current detection resistor Rd inserted between the high-side MOSFET and a positive power supply +V, and an output of an output voltage detection circuit for detecting the voltage amplitude of an analog signal from a low pass filter for modulating an output of a class D amplifier stage are inputted to the threshold value adjustment circuit. The threshold value adjustment circuit adjusts the threshold value in such a manner that a limit current of the MOSFET is set as the threshold value when the output voltage is large, and protection operation is started in response to a lower current than the limit current when the output voltage is small.

摘要： A lateral PNP transistor PB and a lateral NPN transistor NB are serially connected between an input terminal and a reference potential (ground potential). In the transistor PB, a diode D1 is formed. In the transistor NB, a diode D3 is formed. When an ESD of +2000 V is input, the transistor NB turns on, whereas when an ESD of −2000 V is input, the transistor PB turns on. The level of a positive signal capable of being input is limited by the inverse breakdown voltage (e.g., 18 to 50 V) of the diode D3, whereas the level of a negative signal capable of being input is limited by the inverse breakdown voltage (e.g., 13 to 15 V) of the diode D1.

摘要： Speaker system is constructed of a plurality of speakers each including a bass-reflex type cabinet. The speaker system is designed to differentiate a low-band resonance frequency between the speakers by differentiating inner cubic capacities of the speaker cabinets from each other. Audio signal of a different channel is input to each of the speakers, and only low-frequency signals of all of the channels are added together so that the added result is supplied to all of the speakers. Thus, using the differentiated low-band resonance frequencies, the speaker system permits reproduction of low-pitched sounds with a flat characteristic.

摘要： A pseudo-stereo circuit is provided which processes an input monophonic signal into stereophic audio signals. A phase-shift circuit shifts a phase of the input monophonic signal by a phase shift amount that depends upon a frequency of the monophonic signal, to produce an output signal having a gain with respect to the input monophonic signal which is equal to or larger than a predetermined level over an entire frequency band thereof, and reaches a peak at a frequency at which the phase shift amount of the output signal with respect to the input monophonic signal assumes a value equal or closer to −&pgr;. A mixing circuit produces a first mixed signal by mixing a signal obtained by inverting a phase of the output signal of the phase-shift circuit with the input monophonic signal by a first mixing ratio, and produces a second mixed signal obtained by mixing the output signal of the phase-shift circuit with the input monophonic signal by a second mixing ratio. The mixing circuit generates the first mixed signal as a first audio signal carried by one of left and right channels that provide stereophonic audio signals, and generates the second mixed signal as a second audio signal carried by the other of the left and right channels.

摘要： An electro-coagulation printer uses an electrode control unit to drive electrodes which are aligned in proximity to a rotation drum having a conductive ink film on its surface. The electrodes are respectively electrified to partially coagulate the conductive ink film to form ink dots on the surface of the rotation drum, so that the ink dots are transferred onto a paper. Herein, the electrode control unit receives print data from a host device by way of an interface. Gradation data representing gradation values for one line of the electrodes are created based on the print data and are output in a serial manner. The serial gradation data are converted to parallel data corresponding to the gradation values, which are held and controlled in output timing. Based on the gradation values, pulse signals are generated to drive the electrodes respectively.

摘要： A sound field processor having amplitude/phase conversion circuits for left and right channels of a stereophonic signal. The amplitude/phase conversion circuits for left and right channels have substantially the same circuit structure. Each of the amplitude/phase conversion circuits has an inversion amplifier, an amplitude/phase characteristic changing circuit that changes amplitude and phase characteristics of an output from the inversion amplifier, and a feedback device that add outputs from the amplitude/phase characteristic changing circuit and outputs from the inversion amplifier to an input signal to generate a sum signal and feed back the sum signal to the inversion amplifier. An output from the inversion amplifier for the left channel and an output from the amplitude/phase characteristic changing circuit for the right channel are added by a first adder device. An output from the inversion amplifier for the right channel and an output from the amplitude/phase characteristic changing circuit for the left channel are added by a second adder device. An output from the amplitude/phase characteristic changing circuit is fed back through a feedback path between an output and an input of the amplitude/phase characteristic changing circuit. A D/A converter is interposed in the feedback path to adjust the level of the feedback signal to perform bass control.
