    • A pilot valve device adapted to be brought to an open position in response to a mechanical signal so as to cause a compressed fluid to actuate an operating valve. The pilot valve device comprises a main valve located in a pilot valve chamber, and a daughter valve located in a daughter valve chamber formed in the main valve. When a mechanical signal is applied to the daughter valve and brings the same to an open position, a compressed fluid contained in the pilot valve chamber is introduced into a main valve actuating chamber, with the result that the main valve is brought to an open position to permit the compressed fluid to flow into an operating valve actuating chamber.
    • 一种先导阀装置,其适于响应于机械信号而进入打开位置,以便使压缩流体致动操作阀。 先导阀装置包括位于先导阀室中的主阀和位于主阀中形成的子阀室中的子阀。 当机械信号被施加到子阀并将其引到打开位置时,包含在先导阀室中的压缩流体被引入到主阀致动室中,结果主阀处于打开位置 以允许压缩流体流入操作阀致动室。

    • There is provided a radar apparatus for detecting a target. A detection signal generating unit generates detection signals of the target based on transmission and reception waves of antennas. A detection signal processing unit performs frequency analysis on the detection signals to extract signal components of the target, and performs a predetermined process on the signal components to calculate at least one of a distance to the target, a relative speed to the target, and an orientation of the target. The detection signal generating unit includes a filter unit for giving changes to the detection signals in a frequency bandwidth higher than Nyquist frequency which is a half a sampling frequency. The detection signal processing unit acquires the signal components from the detection signals to which the filter unit gives the changes to determine whether the signal components are generated by replication due to the Nyquist frequency.
    • 提供了一种用于检测目标的雷达装置。 检测信号生成部基于天线的发送接收波生成目标的检测信号。 检测信号处理单元对检测信号进行频率分析以提取目标的信号分量,并且对信号分量执行预定处理,以计算与目标的距离,与目标的相对速度和目标的相对速度中的至少一个,以及 目标的方向。 检测信号生成单元包括滤波器单元,用于在高于采样频率的一半的奈奎斯特频率的频带宽度中改变检测信号。 检测信号处理单元从滤波器单元给出改变的检测信号获取信号分量,以确定由于奈奎斯特频率是否由复制产生信号分量。
