    摘要： An apparatus for detecting a liquid level includes a warning device for warning a low liquid level, and a regulator for controlling power supply to the warning device from a power source. The regulator comprises a switch for switching its condition in accordance with the liquid level. The ON condition of the switch indicates that the present liquid level is lower than a predetermined liquid level. The regulator further comprises a thermistor connected to the switch in series. The thermistor has a characteristic of decreasing the resistance value thereof, when a predetermined delay period of time as a function of atmospheric temperature has elapsed since the start of applying the voltage on the thermistor, synchronizing with turning the switch on. The low resistance value of the thermistor allows the power for activating the warning device to be supplied to its device, while the switch is turned on.

    摘要： A device for optically tracking information recorded on an optical disc wherein a photodetector is disposed on the optical axis of an optical system for guiding diffracted waves to the photodetector. The origin of a fictitious X-Y coordinate system at the photodetector is placed on the above-mentioned optical axis, X- and Y-axes of the coordinate system are made parallel to and perpendicular to an information track having the information pits on the rotating recording medium, and the photodetector is divided into four equal parts. A first summation signal indicating the sum of output signals from the four parts of the photodetector is converted into a binary signal, and a difference signal between second summation signals each indicating the sum of output signals from a pair of photodetector parts facing each other with the origin of the coordinate system therebetween is converted into another binary signal. A signal indicating a direction in which the light beam deviates from the information track, is formed on the basis of the above-mentioned binary signals, and a tracking signal indicating the deviation of the light beam from the information track is formed by full-wave rectifying the difference signal and modifying the rectified signal with the above-mentioned direction indicating signal.
