摘要： A channel switching network, in which each cross-point of a switch matrix is constituted as a channel switch of balanced type using two PNPN semiconductor elements. Each of the two PNPN semiconductor elements is arranged in a forward direction with respect to a direct current flowing from the channel switching network to a corresponding terminal equipment. A column of cross-points and a line of cross-points in the switch matrix are designated to select a simultaneously designated cross-point in response to a pair of selection signals. A control circuit is provided for each pair of the incoming lines and the outgoing lines of the switch matrix so that the terminal voltage of a power source for flowing the direct current in the PNPN elements is controlled to temporarily rise to turn ON the PNPN elements at the selected cross-point and thereafter to drop to such a value as only to maintain the PNPN elements in the ON states.

摘要： A method of diametrically contracting a cylindrical body, includes the steps of grasping the cylindrical body with a plurality of elongated grasping members, preparing a cylindrical drawing die having an opening at one end and a tapered inside peripheral surface, drawing the grasping members together with the cylindrical body into the drawing die, through the opening, and applying a compression force to the cylindrical body through the grasping members due to the passage along through the tapered inside peripheral surface, to thereby cause the cylindrical body to be diametrically contracted. During the drawing process, since the cylindrical body does not come into direct contact with the drawing die, neither scratches nor baking cracks are produced on the outside surface of the cylindrical body.
摘要翻译：一种直径收缩圆柱体的方法包括以下步骤：用多个细长的把持件抓住圆柱体，制备一端具有开口的圆柱形拉伸模具和锥形内圆周表面，将夹持件与圆柱体通过开口穿过拉伸模具，并且由于通过锥形内周面而通过抓持构件向圆筒体施加压缩力，从而使圆柱体径向收缩。在拉伸过程中，由于圆筒体不与拉模相接触，所以在圆柱体的外表面上既不产生划痕也不产生烘烤裂纹。

摘要： A click tone removing system for a time division switching system which performs switching of speech channels by a highway switch inserted in a highway. When a hook information detector and a dial information detector detect hook information and a dial information, respectively, delivery of a PCM speech sending signal to the highway is prevented by a blocking function for a fixed period of time, so that the highway is controlled to switch the speech channel, thereby removing a click tone generated by dialing. A subscriber's circuit of an exchange, which changes over a speech sending highway and a speech receiving highway by means of a highway switch, is characterized by the provision of an A/D converter for digitizing a speech sending signal to a digitized speech sending signal sent out to the speech sending highway, a D/A converter for converting a digitized speech receiving signal applied from the speech receiving highway into an analog signal, a gate for gating the input signal to the D/A converter, and a control circuit for controlling the gate, so that during real time processing the speech receiving signal highway is interrupted by opening and closing the gate without controling the higway switch.
摘要翻译：一种用于时分切换系统的点击音消除系统，其通过插入高速公路的高速公路开关来执行语音信道的切换。当挂钩信息检测器和拨号信息检测器检测到挂钩信息和拨号信息时，分别通过阻塞功能在一段固定的时间段内将PCM语音发送信号发送到高速公路，使得公路被控制到切换语音通道，从而消除通过拨号产生的点击音。通过公路交换机在语音发送高速公路和语音接收公路上改变的交换机的用户电路的特征在于，提供用于将语音发送信号数字化到发送的数字化语音发送信号的A / D转换器用于将从语音接收公路应用的数字化语音接收信号转换成模拟信号的D / A转换器，用于将输入信号选通到D / A转换器的门，以及用于控制的控制电路门，使得在实时处理期间，通过打开和关闭门而中断语音接收信号高速公路，而不控制高速开关。
