    • Calculating a highly accurate locus is a goal. An administrative part (20) for correcting a traveling locus of a mobile object (V) is characterized by including an evaluation function generating unit (21) that sets a plurality of nodes on locus data of the mobile object (V) acquired by a wheel rotation quantity measuring unit (16), correlates position data of the mobile object (V) acquired by the wheel rotation quantity measuring unit (16) to the nodes and correlates position data of the mobile object (V) acquired by other units of measurement means than the wheel rotation quantity measuring unit to the nodes, represents positions at which the nodes may occur by probability, represents positions at which position data correlated to the nodes may occur by probability, and calculates an evaluation function including the nodes and the position data as variables, based on each probability; and a locus optimization calculation unit (22) that calculates a locus on which each node occurs with largest probability, based on the evaluation function.
    • 计算高精度的轨迹是一个目标。 用于校正移动物体(V)的行驶轨迹的管理部分(20)的特征在于包括评估函数生成单元(21),其设置由车轮获取的移动体(V)的轨迹数据上的多个节点 旋转量测量单元(16)将由车轮旋转量测量单元(16)获取的移动体(V)的位置数据与节点相关联,并且将由测量装置的其他单元获取的移动体(V)的位置数据相关联, 相对于节点的车轮旋转量测量单元,表示以概率出现节点的位置,表示通过概率与节点相关的位置数据的位置,并且计算包括节点和位置数据的评估函数, 变量,基于每个概率; 以及轨迹优化计算单元,其基于所述评估函数,以最大概率计算出每个节点出现的轨迹。

    • A seal mechanism for butterfly valve of concentric opening with press contacting seal, which comprises a ring-formed seal metal arranged surrounding the valve body under insertion in a radially displaceable manner in a circumferential groove formed around the circumference of the valve body, said seal metal having a rounded outer peripheral face; a seal metal disposed surrounding the inner wall of the valve casing and formed integrally therewith, with its seat face inclining relative to the conduit direction of the valve casing; and two tubular buffer rings inserted in said groove of the valve body in between the bottom of the groove and the inner circumference of the seat metal, each of said tubular buffer rings being split along its entire looping length on the upper or lower side of the ring so as to leave a C-shaped cross section to thereby provide a resilient support for said seal metal on said groove bottom at the neutral position on the seat face between the thrust force components in the inflow and the outflow directions of the valve.
    • 一种具有压力接触密封的同心开口的蝶阀的密封机构,其包括围绕阀体的环形密封金属,该环形密封金属以可径向移动的方式插入围绕阀体的圆周形成的圆周槽中,所述密封金属 具有圆形的外周面; 密封金属,其设置在所述阀壳体的内壁周围并与其一体形成,其阀座面相对于所述阀壳体的导管方向倾斜; 以及两个管状缓冲环,其插入在所述槽体的所述凹槽之间的所述凹槽的底部和所述座椅金属的内周之间,每个所述管状缓冲环沿其整个环形长度在所述槽的上侧或下侧分开 以便留下C形横截面,从而在阀门的流入和推出方向上的推力分量之间的座面上的中间位置为所述凹槽底部的所述密封金属提供弹性支撑。
