    摘要： A tracking control apparatus includes an A/D converter, an edge detection circuit, a latch circuit and a ROM to change a tracking error signal having a sinusoidal characteristic representing a relative position of a light beam and a track on a disk to have a sawtooth characteristic representing the relative position. Stable tracking control free from off-tracking due to a disturbance is attained even when amplitudes of the tracking error signal and a tracking sum signal are not equal.

    摘要： An input analog signal is converted into a corresponding digital signal. A predetermined time segment of the digital signal is selected. A memory stores the selected time segment of the digital signal. A line counter counts horizontal scanning lines of an output video signal. The selected time segment of the digital signal is read out from the memory in synchronism with a horizontal sync signal in a direction of a time axis. An output signal from the line counter and the readout time segment of the digital signal are compared, and a video signal is generated which represents a waveform of a time segment of the input analog signal which corresponds to the selected time segment of the digital signal in synchronism with a vertical sync signal. The video signal is fed to the display section of the television receiver, and the waveform is indicated by the display section of the television receiver.

    摘要： At least a part of a protective layer (1, 4a, 4b, 5a, 5b, 6a, 6b,6c, 7, 8a, 8b) provided on the outer surface of a capacitance generating portion (2) of a film capacitor is constructed from a substantially non-oriented polyphenylenesulfide film (10). Since the non-oriented polyphenylenesulfide film (10) substantially does not accompany thermal shrinkage when it is heat stuck or soldered, and it absorbs the deformation due to the thermal shrinkage of other layers of the protective layer, the sticking stability and dimensional stability in the protective layer can be ensured. As a result, the thermal resistance of the protective layer and the thermal resistance of the capacitor can be improved as well as the simplification of sticking process or omission of an adhesive becomes possible. Moreover, this can serve to further miniaturization of capacitors.

    摘要： A focus servo system for an optical video disc player. A pair of signals generated by two pairs of photo-cells are supplied to an adder and a differential amplifier, an output signal of the adder is supplied to a first comparator and an output signal of the differential amplifier is supplied to a second comparator. When an output signal of the adder reaches a reference voltage of the first comparator, a focus servo pull-in range is detected. Thereafter, when an output signal of the differential amplifier reaches a reference voltage of the second comparator, a stable operation condition of the focus servo system is detected and a servo system loop is closed so that a malfunction is prevented.
