    • A process for preparing a polyalkylene oxide having allyl end-group, by subjecting an alkylene oxide monomer to addition polymerization in the presence of potassium hydroxide in an amount of 2 to 30% by mole to the monomer at a temperature of 20.degree. to 100.degree.C., and reacting the polymerized alkylene oxide with an allyl halide compound, or by subjecting the monomer to addition polymerization in the presence of potassium hydroxide, reacting the polymerized alkylene oxide with an organic polyhalide and then reacting with an allyl halide compound. Potassium hydroxide is preferably employed in combination with the specific initiator. There can be prepared polyalkylene oxide of which all of the chain ends are substantially allyl group.
    • 一种制备具有烯丙基端基的聚环氧烷烃的方法,该方法是在二氧化碳单体在氢氧化钾存在下,在20〜100℃的温度下,以2〜30摩尔%的量进行加成聚合。 使聚合的烯化氧与烯丙基卤化物反应,或在氢氧化钾存在下使单体进行加成聚合,使聚合的烯化氧与有机多卤化物反应,然后与烯丙基卤化物反应。 氢氧化钾优选与特定引发剂组合使用。 可以制备其全部链端基本上是烯丙基的聚环氧烷。

    • A course guidance system includes a direction sensor and a speed sensor both fitted to a moving body, a display mounted in the moving body and a map displayed in a manner corresponding to the display surface of the display and in which the present position of the moving body is derived by the direction sensor and the speed sensor and is plotted on the display in a manner corresponding to the map. The improvement comprises a locus memory for sequentially storing an X component value and a Y component value of the driving position based on a predetermined driving distance obtained from the speed sensor and on the driving position obtained from the direction sensor, a locus display memory for storing data in a manner corresponding to the display surface of the display, the data being obtained by reading the contents of the locus memory in a manner corresponding to the scale of reduction of the map, and a display for plotting the driving locus of the moving body on the display surface based on the contents of the locus display memory, wherein the data to be read when the contents of the locus memory is transferred to the locus display memory are divided into a plurality of groups each consisting of a data line to be read at a predetermined interval which are sequentially read and transferred, and the plotted line of the driving locus to be displayed is displayed sequentially and progressively from a rough display to a dense display.
