    Abstract: A vehicle-mounted radar includes a transmission antenna for radiating a radio wave and three antennas including first, second and third reception antennas for receiving reflected wave of the radio wave from an object, wherein a horizontal width of the second reception antenna is less than a horizontal width of each of the first and third reception antennas. It then becomes possible to separately detect two objects, such as two preceding vehicles, each of the rate and distance to the radar mounting vehicle of which is identical with each other, as two objects.

  • Patent number: 6881954
    Abstract: A scanning probe microscope has an XY scanner for making a probe scan a sample surface, an approach and separate drive element for making the probe approach to the sample surface at a sampling position and separate the probe from the sample surface during movement between the sampling positions, and a servo controller for holding the distance between the probe and the sample surface at a reference distance during measurement at the sampling position. A plurality of scattered measurement locations are set away from each other as sampling positions. The approach and separation movements are performed at each sampling position. When measuring the surface by the probe at a sampling position and while making the probe move between sampling positions, servo control by the servo controller is continued. This makes it possible to quickly measure the surface by a simple controller and possible to measure a wide area or measure a high aspect ratio.

  • Patent number: 6854548
    Abstract: An automobile running control system having “Fast follow-up” and “Slow follow-up” modes controls so that the automobile may cruise at an optimum car-to-car space between the automobile and an object which is selected among those detected and faster than a preset ground velocity in the “Fast follow-up” mode. When the fast follow-up velocity of the automobile falls under the preset velocity, the system automatically enters the “Slow follow-up” mode.

  • Patent number: 6836021
    Abstract: A reduction in a size of a multichip module having a plurality of chips (higher-density mounting) and improvements in the reliability and functionality thereof are intended. By alternately repeating stacking in layers and processing of insulating films and conductive films, a microcomputer chip is face-down bonded to an upper portion of a wiring substrate having build-up substrate portions formed with wires with a surface of the microcomputer chip formed with a bump electrode facing downward. Memory chips are bonded onto an upper portion of the microcomputer chip with the respective surfaces thereof formed with bonding pads and the like facing upward.

  • Patent number: 6825756
    Abstract: The invention provides a radar system, which can increase a crossrange detection speed in the lane change state by employing a steering angle sensor, etc. loaded on a vehicle without providing additional hardware. A lane-change determining unit receives a yaw rate response from a steering angle sensor, etc., and determines whether the radar-loaded vehicle is in the steering operation for lane change. If the radar-loaded vehicle is in the lane change state, a gain setting unit shifts a tracker gain to a larger value than that in ordinary running, and calculates a range, a crossrange, a relative velocity, etc. relative to a target from the results of tracker processing executed by a filtering unit. By using the calculated range, crossrange, relative velocity, etc., a control determining unit determines whether there is a collision risk, and whether steering operation to avoid a collision is required.

  • Publication number: 20040138802
    Abstract: In a vehicular control device, it is necessary to measure or calculate six physical quantities-forward-reverse speed, left-right speed, vertical speed, pitch angle, roll angle, and angle of sideslip-representing vehicular movement and to control the braking force of each wheel and/or the damping coefficient of each suspension shock absorber in order to further shorten braking distance particularly at the time of braking and to prevent spin at that time. In this case, it is necessary to furnish sensors to measure speed and angle directly. In the present invention, four radar sensors are used in order to directly measure the forward-reverse speed and the left-right speed. Also, the vertical speed, the pitch angle, the roll angle, and the angle of sideslip are indirectly measured from the output of the radar sensors.
