    摘要: To provide a small-sized and lightweight gearshift operating device that is capable of performing a gearshift operation in a short time at low power consumption, a guide slit having a plurality of slits 41 parallel with the shift fork shafts and a plurality of slant slits 42 concentrated to a neutral point 43 from them is employed to guide a follower 33. The follower 33 is operated along the guide slit, thus the number of times of starting and stopping operations of the motor for the shift operation is reduced, and the load of the actuator for the selection operation is reduced.

    摘要: The present invention provides a VCM driver realizing low power consumption and high accuracy and a PWM amplifier compensating a dead time distortion. A phase compensator, a ΔΣ modulator receiving an output signal of the phase compensator and converting the output signal to a control code of predetermined bits, a PWM modulator receiving the control code to produce a PWM signal, and an output circuit receiving the PWM signal to drive a voice coil constitute a forward path. A sense amplifier sensing a current of the voice coil, an ADC receiving an output signal of the sense amplifier, a low-pass filter receiving an output signal of the ADC, and a decimation filter receiving an output signal of the low-pass filter constitute a feedback path. An output signal of the decimation filter is fed back to the input side of the phase compensator to form a major feedback loop having a first-order characteristic loop gain. An output signal of the decimation filter is fed back to the output side of the phase compensator to form a minor feedback loop having a loop gain which is flat until a target band frequency when viewed from the output side of the phase compensator.

    摘要: The present invention provides a switching regulator having good stability compatible with a good response and an enhanced protection function. A first capacitor is placed between an output end of an inductor to generate an output voltage and a ground potential. From input voltage, a current is supplied to the inductor's input end by a first switch element. A first feedback path includes a hysteretic comparator. An output voltage added to a voltage proportional to the current flowing through the inductor is supplied to the hysteretic comparator which discriminates whether the voltage is appropriate by hysteresis characteristics and generates a PWM control signal in accordance with an output current variation. Moreover, a second feedback path is provided to feed back an error amplifier output voltage with greater gain in a low frequency domain and an attenuation loop around a PWM frequency band to the comparator's reference voltage input terminal. Feedback voltage through the second feedback path is used as a monitoring voltage in a protection circuit.
