    • The invention provides an apparatus, and a method, for detecting the tread profile of a tire mounted about an X-axis comprising a non-contact Y detection means movable in parallel to the X-axis for measuring the distance at a right angle between such means and the peripheral surface of the tread profile in the direction of the Y-axis, X detection means for detecting the position of the Y detection means along the direction of the X-axis, data memory means for storing X and Y data pairs obtained by both such detection means, and radius calculating means for calculating the radius of the article from the X and Y data stored in the data memory means. The radius calculating means includes division means for dividing the X and Y data for a plurality of portions of the tread profile based on predetermined reference values for the tread profile of the tire being measured and arithmetic means for determining the radii of the respective portions each from the corresponding data divided by the division means, the arithmetic means determining the circle equation of: x.sup.2 +y.sup.2 +ax+by+c=0, from the X and Y data to calculate the radius of the tread profile, the coefficients a, b and c of the circle equation being determined by least square approximation.
    • 本发明提供了一种用于检测围绕X轴安装的轮胎的胎面轮廓的装置和方法,包括可以平行于X轴移动的非接触Y检测装置,用于测量这样的直角之间的直角距离 在Y轴方向上的胎面轮廓的装置和外围表面,用于检测Y检测装置沿着X轴方向的位置的X检测装置,用于存储获得的X和Y数据对的数据存储装置 以及半径计算装置,用于根据存储在数据存储装置中的X和Y数据计算物品的半径。 半径计算装置包括分割装置,用于根据用于所测量的轮胎的胎面轮廓的预定参考值来划分胎面轮廓的多个部分的X和Y数据;以及算术装置,用于确定各自部分的各部分的半径 相应的数据除以除法装置,运算装置根据X和Y数据确定圆方程:x2 + y2 + ax + + + c = 0,计算胎面轮廓的半径,系数a,b 圆方程的c由最小二乘近似确定。

    • A telephone exchange system useful for a bank or brokerage house speech system or the like, which can accommodate a large number of lines (or trunks) and permit improvement of the reliability and call connection processing capacity. The system comprises exchange sub-systems A (EX-A) and B (EX-B) capable of independently executing an exchange operation and each accommodating a terminal. The terminal, on the other hand, has a speech channel switch for connecting a speech channel including a handset to either exchange sub-system A (EX-A) or B (EX-B). When a process of connecting a call is brought about in the terminal, that terminal selects one of the exchange subsystems and controls the speech channel switch for connecting the call to the selected exchange sub-system.
    • 一种可用于银行或经纪公司语音系统等的电话交换系统,其可以容纳大量线路(或中继线),并允许提高可靠性和呼叫连接处理能力。 该系统包括能够独立地执行交换操作并且各自容纳终端的​​交换子系统A(EX-A)和B(EX-B)。 另一方面,终端具有用于将包括手机的语音信道连接到交换子系统A(EX-A)或B(EX-B)的语音信道切换。 当在终端中产生连接呼叫的过程时,该终端选择交换子系统中的一个并控制用于将呼叫连接到所选择的交换子系统的语音信道交换机。
