  • Patent number: 4719582
    Abstract: A method and apparatus for determining the chemical structure of an unknown substance wherein spectral data of the unknown substance is detected, a point-assessment is calculated which expresses the degree of possibility of partial structures being contained in the unknown substance based on the spectral data and prememorized chemical shift values corresponding to the partial structures of known substances, it is judged whether the point-assessment is a predetermined threshold value or more and the partial structures with a large possibility of being contained in the unknown substance based on the output of the judgement results are found and displayed. The partial structures thus found are used to determine a molecular structure of the unknown substance.

  • Patent number: 4515737
    Abstract: A process for producing a composite plastic pipe, which comprises producing a thermoplastic resin pipe (I) by an extruder, covering the surface of the pipe (I) uniformly with a continuous fibrous reinforcing material (II) impregnated with a thermosetting resin in its axial direction by a draw molding method, helically winding a continuous fibrous reinforcing material (III) impregnated or not impregnated with a thermosetting resin uniformly on the layer of the resin fibrous reinforcing material (II) by a filament winding method, thereafter curing the thermosetting resin by irradiation of ultraviolet light and coating a thermoplastic resin (IV) on the resulting product within a crosshead die in an extruder.
