  • Publication number: 20200282673
    Abstract: Provided are a method and a device for producing a pultruded material that improve the homogeneity of a thermosetting resin. The device for producing a pultruded material comprises a first opening section, a second opening section, a closing section, a tension-applying section, an impregnating section, and a mold. The first opening section and the second opening section open a bundle of reinforcing fibers and thereby obtain a bundle of reinforcing fibers. The closing section closes the bundle of opened reinforcing fibers and thereby obtains a bundle of reinforcing fibers. The tension-applying section applies tension along the direction in which the reinforcing fibers extend to the bundle of reinforcing fibers that pass through the closing section. The impregnating section impregnates the bundle of reinforcing fibers with a thermosetting resin. The mold pultrudes the bundle of reinforcing fibers that have been impregnated with the thermosetting resin.

  • Patent number: 10386314
    Abstract: Electrons excited by irradiation of a visible light to a sample is at an energy level lower than a vacuum level, thus photoelectrons are not emitted from the sample and energy of excited electrons cannot be measured. The visible light is irradiated to the sample through a mesh electrode. A surface film for reducing the vacuum level is formed on a surface of the sample. With the surface film being formed, photoelectrons are obtained by the visible light, and these photoelectrons are accelerated by the mesh electrode toward a photoelectron spectrometer. Ultraviolet light may be irradiated to the sample and metal having same potential therewith. In this case, the mesh electrode is set at a retracted position to prohibit interaction of the mesh electrode and the ultraviolet light. A difference between the valence band and the Fermi level of the sample can be measured.
