    • A control system for a hydrostatic power transmission having a variable displacement hydraulic pump (2) and a hydraulic actuator (3) connected in a closed or semi-closed circuit, wherein the displacement of the pump or the delivery thereby is adjustable in accordance with a manipulated variable of an operating lever (13). A control unit of the system (16) is operative to calculate a hydraulic pump displacement command (X) on the basis of a manipulated variable signal (X.sub.L) and circuit pressure signals (Pa, Pb) in such a manner that when the delivery side circuit pressure is higher than the suction side circuit pressure, the displacement is controlled to change in accordance with the manipulated variable while the rate of change in the displacement is controlled to change a maximum rate when the circuit pressure on the delivery side is below a pressure value that varies in dependence on the manipulated variable and is reduced once it is reached, while pump displacement is changed in response to the suction side circuit pressure, when it is higher than the delivery side pressure, in a similar manner except that a constant value is used instead of a value which varies in dependence on the manipulated variable.
    • 一种用于静液压动力传动的控制系统,其具有连接在闭合或半闭合回路中的可变排量液压泵(2)和液压致动器(3),其中泵或其输送的位移可根据 操作杆(13)的操纵变量。 系统(16)的控制单元可操作以基于操纵可变信号(XL)和电路压力信号(Pa,Pb)计算液压泵排量指令(X),使得当输送侧 回路压力高于吸入侧回路压力,根据操作变量控制位移变化,同时当输送侧的回路压力低于压力时控制位移变化率以改变最大速率 值根据操作变量而变化,并且一旦达到就减小,而泵位移响应于吸入侧回路压力而变化,当其高于输送侧压力时,除了使用恒定值 而不是根据操纵变量而变化的值。

    • A positioning apparatus for positioning an object in respective axis directions of an X-axis, a Y-axis perpendicular to the X-axis, and a Z-axis orthogonal to the X-axis and the Y-axis and positioning the object around the Z-axis within a plane parallel to the X-axis and the Y-axis is provided. A fastener detachably fastens the retainer. A gap is formed between a first reference surface of the retainer and the second reference surface of the fastener when a fixing shaft of the retainer is inserted into a fixing hole of the fastener, an outer surface of a pyramid part of the fixing shaft fits to an inner surface of the fixing hole and the object is positioned in the X-axis direction and the Y-axis direction. The first reference surface and the second reference surface come into contact with each other when a fastening part of the fastener pulls the fixing shaft, the pyramid part or the fixing hole elastically deforms, and the fixing shaft is further pulled into the fixing hole with maintaining the fitting between the outer surface of the pyramid part and the inner surface of the fixing hole.
    • 一种定位装置,用于将物体定位在与X轴垂直的X轴,Y轴和X轴和Y轴正交的Z轴的各轴线方向上,并将物体围绕 提供与X轴和Y轴平行的平面内的Z轴。 紧固件可拆卸地固定保持器。 当保持器的固定轴插入到紧固件的固定孔中时,在保持器的第一参考表面和紧固件的第二参考表面之间形成间隙,固定轴的金字塔部分的外表面适合 固定孔和物体的内表面位于X轴方向和Y轴方向上。 当紧固件的紧固部分拉动固定轴,金字塔部分或固定孔弹性变形时,第一参考表面和第二参考表面彼此接触,并且固定轴进一步被拉入固定孔中,同时保持 金字塔部分的外表面和固定孔的内表面之间的配合。
