Abstract: A method of adjusting the temperature properties of piezoelectric devices and oscillation circuits which have a third-order function temperature property and the point of inflection of the third-order function temperature property outside the normal usage temperature range. The local maximum point or local minimum point temperature located in the normal temperature range is regarded as the peak temperature of the apparent second-order function temperature property, and the peak temperature is adjusted to the optimum value in the normal temperature range by rotating the temperature property around the point of inflection located outside the normal temperature range by adjusting the first-order coefficient.

Abstract: In a clock shaping circuit, a phase comparator 31, a selector 76, a loop filter 2, and a VCSO/VCXO 4 form a PLL circuit's main feedback loop during normal operation. When the main feedback loop of the PLL circuit malfunctions due to unlocking, a quartz crystal oscillator circuit is used, and a PLL circuit's backup feedback loop is established, which includes a backup phase comparator 74, the selector 76, the loop filter 2, and the VCSO/VCXO 4.

Abstract: The invention provides an oscillator and a control method for controlling the oscillator which reliably oscillates even when the oscillator is driven at a low voltage. An oscillator repeats a startup operation and a suspension of the startup operation by turning on and off a switch with half a period of a Schmitt trigger oscillator circuit, until a piezoelectric oscillator circuit is put into a normal oscillation state. The oscillator thus creates a number of opportunities of transient response allowing the oscillation amplitude of the piezoelectric oscillator circuit to grow, and reliably oscillates.

Abstract: An optical pickup provided opposed to an optical disc D is moved in the optical axis direction with a drive signal from a focus search circuit to detect, with an amplitude detecting circuit, the character “S” shape waveform of large amplitude corresponding to the recording surface of optical disc of the focus error signal FE obtained from the optical pickup and such detected output is counted by a counter. When the character “S” shape waveform of large amplitude appears twice, an interval thereof is measured with a time measuring circuit and width of interval is detected with an interval detecting circuit. The counted value of counter and detected output of the interval detecting circuit are supplied to a microcomputer to automatically detect a type of optical disc. Thereby, a reproducing device which can be used for a plurality of reflection type optical discs may be structured.

Abstract: A tracking error signal calculation circuit has peak detection multiplication circuits which detect the peaks of the detection signals of left and right regions of a photodiode and multiply a coefficient for detecting the deviation of the beam light with respect to the track of the disc recording medium, subtraction circuits for removing an offset by subtracting these multiplication results from the detection signals, and a subtraction circuit which calculates a difference of the signal obtained by removing the offset (performs push-pull operation) and outputs a tracking error signal. The value of the coefficient can be changed by adding an alignment signal to the detection signal. In order to impart the frequency dependency to this coefficient, the alignment signal is added to the signal through a filter.
