    摘要: 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.

    摘要: A method of moulding foamed synthetic resin pellets of polyolefine in a mould, wherein the synthetic resin pellets are prepared with volumne of closed cells being more than 65 % of the total volume of the total cells and having an inorganic gas in the cells at a pressure higher than 1.18 atmospheres, then filled in a mould which is not completely gas tight, and then heated to expand and tightly adhere to each other. The pressure in the mould can be lower than ordinary pressure or at a vacuum and the pressure of the resin can be at a pressure higher than ordinary pressure. The moulded product may be removed from the mould after cooling or during cooling when the inner temperature of the product is between its melting point and a temperature 50.degree.C below the melting point. The obtained product may be stored at a temperature of 30.degree. to 70.degree.C below the melting point.

    摘要: 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.
