    • A method and apparatus for manufacturing bent pipes of a composite material composed of resin and filling materials such as reinforcing materials and aggregates by employing a cylindrical molding tool which is deformable between straight-axis form and bent-axis form. Materials are supplied into the molding tool held in horizontally straight condition while the tool is rotated about a horizontal axis, and are molded into a pipe by centrifugal molding. Rotation of the tool is stopped when the pipe molded therein is in uncured state, then the tool is subjected to bending. The resulting bent pipe is removed after it is cured. Before the tool is bent, a bag made of a flexible sheet material is inserted into the pipe and inflated to straighten out the inner periphery of the pipe so as to protect the pipe from any possibility of deformation during bending operation. The molding tool is preferably made of such resilient material as rubber, is incased in a peripherally divisible frame or bellows-type flexible frame which, in turn, is suitably incased in a rotary frame. More preferably, the molding tool has a hollow space provided between its inner and outer walls; by filling liquid in the hollow space it is possible to achieve fine roundness in pipe molding irrespective of dimensional errors with the molding tool or frame.
    • 一种用于制造由树脂和填充材料如增强材料和骨料组成的复合材料的弯曲管的方法和装置,该方法和装置采用可在直轴形和弯轴形之间变形的圆柱形模具。 当工具围绕水平轴旋转时,将材料供给到水平直线状态的模具中,并通过离心模塑成型为管。 当模制在其中的管子处于未固化状态时,工具的旋转停止,然后该工具受到弯曲。 所得到的弯管在固化后被去除。 在工具弯曲之前,将由柔性片材制成的袋子插入管中并充气以使管道的内周伸直,以便在弯曲操作期间保护管道不发生变形的可能性。 模制工具优选地由诸如橡胶的弹性材料制成,被包围在可外围可分割的框架或波纹管型柔性框架中,该框架或波纹管型柔性框架进而适当地在旋转框架中被覆盖。 更优选地,模制工具具有设置在其内壁和外壁之间的中空空间; 通过在中空空间中填充液体,可以实现管模中的细圆度,而与成型工具或框架的尺寸误差无关。

    • An internal operation of RF IC is adjusted so that the level of an RF transmitter signal is substantially stopped from rising, or made to descend in course of ramp-up of the RF transmitter signal. This adjustment is enabled by ramp-up adjustment data Last 4 symbols contained in preamble data precedent to real transmission data transmitted after completion of ramp-up. The ramp-up adjustment data and real transmission data are supplied from a baseband LSI. The RF transmitter signal contains phase and amplitude modulation components according to the EDGE system. RF IC includes phase and amplitude modulation control loops PM LP and AM LP. Ramp-up of RF power amplifiers PA1 and PA2 is performed by controlling the gain of the first variable amplifier MVGA included in the AM LP according to ramp information. Thus, unwanted radiation's level is reduced during ramp-up of the RF transmitter signal of the RF power amplifiers.
    • 调整RF IC的内部操作,使得RF发射器信号的电平基本上停止上升,或者在RF发射器信号的上升过程中下降。 该调整通过斜坡调整数据启用,最后4个符号包含在完成斜坡后发送的实际传输数据的前导数据先例中。 从基带LSI提供斜升调整数据和实际发送数据。 RF发射机信号包含根据EDGE系统的相位和幅度调制分量。 RF IC包括相位和幅度调制控制环路PM LP和AM LP。 通过根据斜坡信息控制AM LP中包括的第一可变放大器MVGA的增益来执行RF功率放大器PA1和PA2的上升。 因此,在RF功率放大器的RF发射器信号的斜坡上升期间,有害辐射的电平被降低。
