    摘要: A distance measuring apparatus installed in an automobile to measure with a high degree of accuracy a distance between a road surface and the axle of vehicle body of the automobile in motion. With this distance measuring apparatus, the distance between the point of its installation on the automobile and the road surface is measured by transmitting wave signals from the point of installation toward the road surface, selecting only the reflected wave signals of a predetermined intensity from the received reflected wave signals from the road surface and then integrating and averaging the data of the distance to the road surface derived from the selected reflected wave signals.

    摘要: A novel visitor conversation system comprising a single transmitter-receiver. The distance to an incoming person is measured by receiving an ultrasonic wave signal propagated from the transmitter-receiver and reflected on the person. When the distance is shorter than a predetermined detection distance, it is decided that the person is a visitor. The transmitter-receiver further propagates an ultrasonic wave amplitude-modulated on an audio signal, and the signal received is demodulated for the purpose of a speech. The visitor detection and the conversation with a vehicle carrying a speaking device are performed by a single medium.

A base current of one Tr31 of the differential pair transistors is brought into substantial agreement with a DC component of a current flowing through the sensing diode Q1 (Tr34). A total of currents flowing through the differential pair transistors Tr31 and Tr32 is regulated to a substantially constant value by the current mirror circuit. Thus, the start signal output circuit which is small in size, high in sensitivity and low in power consumption can be realized.

    摘要: A speed control system for a motor vehicle automatically controls a throttle valve so as to allow the vehicle to run at a desired velocity at all times. The system includes a laser radar for detecting a preceding vehicle and measuring the distance therefrom, and a control computer in which a proper distance responsive to a vehicle velocity is set. The control computer discriminates proximity to the preceding vehicle through change in the distance at a certain interval. When the distance exceeds the proper distance, the control computer reduces the desired velocity in case proximity to the preceding vehicle is discriminated at a plurality of times continuously and increases the desired velocity in case no such proximity is discriminated, and when the distance is below the proper distance, the computer decelerates the vehicle by directly controlling the throttle valve in the closing direction, allowing tracing running with the proper distance from the preceding vehicle.

The apparatus includes a magnetic sensing device externally attached to the body of the fuel injection nozzle for sensing a magnetic variation caused by the movement of the pressure pin thereby to detect the displacement of the pressure pin, and a signal processing circuit for amplifying and processing the output signal of the magnetic sensing device, whereby the apparatus is applicable to conventional fuel injection nozzles of Diesel engines without any need to modify the nozzles and makes it possible to detect easily and accurately fuel injection timings of the fuel injection nozzles.

    摘要: It is determined whether each of several subcarriers has an adequate propagation characteristic in a first horizontally polarized wave antenna. Of the several subcarriers, a subcarrier, which is determined to have an adequate propagation characteristic in the first horizontally polarized wave antenna, is assigned with transmission data. A transmission signal containing the transmission data is thereby transmitted from the first horizontally polarized wave antenna. In addition, of the several subcarriers, a subcarrier, which is determined not to have an adequate propagation characteristic in the first horizontally polarized wave antenna, is also assigned with transmission data in either a second horizontally polarized wave antenna or a vertically polarized, wave antenna. A transmission signal containing the transmission data is thus transmitted from the second horizontally polarized wave antenna or the vertically polarized wave antenna.
