摘要： An antenna cover (1) for a radar (2) for a vehicle has a rectangular parallelepiped shape, having a flat cover top (10) that faces a microstrip antenna (21a, 21b) of the radar (2) and a sidewall (11) that covers the microstrip antenna (21a, 21b) sideways. The sidewall (11) is located out of the range where the electromagnetic waves to be received by the microstrip antenna (21a, 21b) are directly received. An inner face (11a) of the sidewall (11) is at a right angle to the cover top (10). An outer face (11b) of the sidewall (11) is at a constant angle θ larger than 0 degree but smaller than 90 degrees, to the inner face (11a) of the sidewall (11). The sidewall (11) is structured such that its thickness increases toward the side where the microstrip antenna (21a, 21b) is present.

摘要： In an integrated optical unit of the present invention, a photo detector (12) and a holding member (17) that sustains a semiconductor laser (11) are provided on a polarizing beam splitter (14). This makes it possible to reduce a deviation from a designed value due to tolerance, and adjust a relative positional relationship between the semiconductor laser (11) and the photo detector (12). Therefore, returned light from an optical disk (4) is accurately adjusted with respect to a division line of a photo-detecting device (13). As a result, stable servo-control is realized, and an information signal with fine quality is obtained.

摘要： In an optical semiconductor package according to the present invention, the component bearing surface of the stem having an outline made up of opposed first and second circular-arc parts, a first straight-line part which connects each end of the first and second circular-arc parts and a second straight-line part which connects each other end of the first and second circular-arc parts. The first and second circular-arc parts have a common center, and the first circular-arc part has a larger radius than that of the second circular-arc part. Thus, the larger space, the space between the first circular-arc part and the center, can be used for disposing the light detector or a polarization split element, and the unused space, the space between the second circular-arc part and the center, will be minimum, thereby realizing downsizing and cost reduction of the device.

摘要： A control portion performs gyro control at control intervals of .DELTA.t, by using -.omega.G, which is obtained by inverting the polarity of an angular rate .omega.G outputted from an angular rate sensor portion. On the other hand, a receiving level is detected at constant control intervals of .DELTA.T (=M.DELTA.t: M is an integer). The rotation of an antenna portion is controlled by using .omega.s, if the receiving level has increased, or by using -.omega.s, if the receiving level has decreased, i.e. by step track control. By accumulating the control amount .+-..omega.s for a predetermined long time period of N.DELTA.T, accumulation of an error contained in each angular rate .omega.G is obtained. The accumulated value is then divided by N to calculate an error .DELTA..omega.G contained in .omega.G. This error .DELTA..omega.G is used to compensate the actual error, so that the gyro control can be made more accurate.
摘要翻译：控制部分通过使用通过使从角速度传感器部分输出的角速度ωG的极性反转获得的ωG来执行DELTA t的控制间隔的陀螺仪控制。另一方面，在DELTA T（= M DELTA t：M是整数）的恒定控制间隔处检测到接收电平。天线部分的旋转通过使用ω-s来控制，如果接收电平已经增加，或者如果接收电平已经减小，即通过步进轨迹控制，则通过使用ωω来控制天线部分的旋转。通过在N DELTA T的预定长时间周期内累积控制量+/- omega，获得每个角速度ωG中包含的误差的积累。然后将累积值除以N，以计算包含在ωG中的误差ΔTAωωG.该误差ΔTAωG用于补偿实际误差，使得可以使陀螺仪控制更准确。

摘要： A radar system includes an arithmetic processing unit, which calculates the second derivative of the intensity of a reflected wave and determines whether a target is an upper structure or a vehicle, based on the second derivative. Alternatively, the arithmetic processing unit decomposes the waveform of the intensity of the reflected wave into frequency components and determines whether the target is an upper structure or a vehicle, based on the intensity of a predetermined frequency component.

摘要： A radar apparatus forming a series-feed array-antenna includes an array antenna having transmission/reception antennas, and each antenna includes a plurality of antenna elements arrayed with feed-lines to be series-connected each other. A calibration line is disposed between the transmission antenna and the reception antenna via a switch which connects or disconnects the calibration line. The signal having a phase shift is transmitted via the calibration line when the switch connects the calibration line and an amount of phase shift from the signal transmitted via the calibration line is calculated based on a reference phase at the transmission antenna thereby calibrating the phase shift.
