摘要： A light-received position detecting circuit includes a light receiving portion 10 formed by plural photodiodes arranged side by side for detecting light to generate a photoelectric current, and a resistor group RR formed by plural resistors RR1 to RRn-1 connected in series and the photodiodes are correspondingly connected to the respective resistors to divide the photoelectric current from a light emitting portion 31 into photoelectric current parts according to the position of generation of the photoelectric current. First and second current detecting amplifiers 12 and 16 for generating detection signals corresponding to the photoelectric current parts are connected to the opposite ends of the resistor group RR, respectively. A third current detecting amplifier 14 for dividing the light receiving portion 10 into light receiving sections and detecting the photoelectric current part is connected to selected one of the resistors located in the intermediate portion of the resistor group RR. The operation of the amplifier 14 is changed over selectively by a switch 18.

摘要： A full wave signal E is compared with a trapezoidal wave signal G in a comparator to output a second comparison signal H. The full wave signal E is obtained through full wave conversion applied to a sine wave signal of a Hall element. The trapezoidal wave signal G is obtained by sampling and holding an attenuated signal F, obtained by attenuating the full wave signal E, at a trailing end of a first comparison signal D, and nulling the attenuated signal F at a subsequent leading end thereof. Then, the first and second comparison signals D, H are added up in an OR circuit to output an addition signal K, so that no drive current IL flows through the driving coils at a point near the former and latter halves of a phase changeover point. Near the former half of a phase changeover a point, the drive current IL is nulled before counter electromotive force Ec becomes small, enabling motor noise reduction. Near the latter half of a phase changeover point, the drive current IL remains zero, continuously from the former half, preventing a drop of efficiency in driving a motor. Since a trapezoidal wave signal G is made from the attenuated signal F, a period with the drive current IL being zero is always ensured near the former half of a phase changeover point.

摘要： In a motor, drive transistors (7, 9) are turned off by drive signals I, J output from a control circuit (10) at a point adjacent to a phase changeover point of the energizing to drive coils (1, 2), so that no drive current flows through the drive coils (1, 2). Since the counter electromotive forces of the drive coils (1, 2) become small, the drive current can be eliminated before the drive current sharply rises. As a result, sharp dropping of the drive current can be prevented. This allows variation in rotational torque of a motor to be suppressed, and thus reduces vibrational noise in the motor.

摘要： The amplitude control of a cantilever based on the van der Pol model is performed through feedback using measurement data on a deflection of the cantilever. A self-oscillating circuit integrates a deflection angle signal of a cantilever detected by a deflection angle measuring mechanism using an integrator, multiplies a resulting integral value by linear feedback gain generated by a gain generator, and an output corresponding to the linear feedback signal is generated. Also, the self-oscillating circuit cubes the deflection angle signal using analog multipliers, integrates the resulting values using integrators, multiplies the resulting integral values by a nonlinear feedback gain generated by a gain generator, and an output corresponding to the nonlinear feedback signal is generated. Furthermore, the self-oscillating circuit adds the outputs together using an adder, and a voltage signal for a piezo element is generated.
