Here is disclosed a photoelectric detector comprising first and second light sources respectively having different light emitting areas, a photoelectric transducer member adapted to receive the light emitted from these light sources and then reflected on an object to be detected, and a signal processing circuit functioning to separate electric signals corresponding to the first and second light sources from an output of the photoelectric transducer member and to compare these separated two electric signals to each other so that presence or absence and a position of the object are detected on the basis of such comparison of the two electric signals.

Apparatus for detecting the presence and position of an object

The gas rate sensor in the present invention is provided with a holder assembly having a metallic holding portion for holding flow sensors and a cylindrical casing containing the holder assembly and heater wires which are wound around the outside thereof. The outer periphery of the holding portion is provided with a plural number of projections which are brought into compressive contact with the inner periphery of the casing for enabling pressing of the holder assembly into the casing. A temperature detection element is disposed in a gas flow passage between the holder assembly and the casing for performing energizing control of the heater wires.

The detection system for obstruction to vehicle according to the invention comprises a plurality of light emitting elements disposed in the rear of a car, a modulation for emitting modulation lights from the light emitting elements, light receiving elements for receiving the reflected light that the modulation light comes in contact with an external obstruction to reflection, a detection circuit for detecting output signals of the light receiving elements, thus detecting the obstruction from an output of the detection circuit, and a rearward obstruction can be detected securely particularly when the car moves backward, a new light source for obstruction detecting is not particularly required, and thus no area must be prepared for installation.

Rearward vehicle obstruction detector using modulated light from the

An automatic light control apparatus for a vehicle comprises an external light detector for selectively turning on and turning off at least one of tail lamps, side marker lamps and head lamps of a vehicle in accordance with the detected external light. A further detector is provided for detecting the ON period of an illuminating light having a fluctuating light value (for example generated by an A.C. voltage source), and the lamps are further controlled in accordance with the detected ON period of the fluctuating light value in conjunction with the signals generated by the external light detector, for controlling the illumination of the lamps of the vehicle. A further detector may be provided for detecting an abrupt change in the illumination level, and for controlling the vehicle lamps further in accordance with the detected abrupt change.
