摘要： There is provided a photoelectric switch in which a beam reflected by an object to be detected is received in a trigonometric manner so that any failure in the distance measurement of the object can be prevented with employment of ordinary amplification circuit for received-light signals without enlarging the figure of the dynamic range of the circuit. In the switch, a circuit for comparing the ratio of the received-light signals to a predetermined operational level includes means for setting the nearest limit point for a set range of a detecting area to be farther than an intersection of the projected light beam with a line connecting centers of light-receiving lens and received-light detecting element so that the detection of the object can be made even when the dynamic range of the amplification circuit is saturated, whereby the presence of the object in the detecting area can be always discriminated even upon the dynamic range saturation of the amplification circuit.

摘要： A map data storage unit holds map data in which a road ID is allocated, as identification information, to every preset section of at least part of roads. A traffic jam determination unit determines whether the section corresponding to every road ID is congested. A transmission unit performs broadcast transmission of vehicle data including a road ID and the traveling speed of a vehicle from the vehicle traveling in each section of a road. At the time, the transmission unit forms a frame in which the received vehicle data of other vehicle and the vehicle data of a driver's vehicle are combined. An information compressing unit compresses an amount of data by deleting the traveling speed from the frame with respect to a section that has been determined not to be congested by the traffic jam determination unit.

摘要： A photoelectric switching apparatus includes a light transmitter part having a first built in oscillator and a detachable light transmitter circuit driven by the first oscillator. A detachable light emitter is provided for emitting light in response to a signal from the light transmitter circuit. A light receiver part includes a photoelectric transducer for converting a light signal incident thereon to a converted electric signal and a second oscillator which is separate from the light transmitter part and can be connected to the light transmitter circuit when the light transmitter circuit and the light emitter together are detached from the first oscillator. The light receiver part has a D-flip-flop which reads input data based on the converted electric signal by utilizing an output signal of the first oscillator as its clock pulse. The first oscillator issues an output signal which is substantially synchronous with the converted electric signal to the D-flip-flop by utilizing a signal based on the converted electric signal when the light transmitter circuit and the light emitter are detached from the first oscillator. The first oscillator issues an output signal which drives the light transmitter circuit, to the D-flip-flop when the light transmitter is connected to the first oscillator.
