According to the present invention, the solid polyelectrolyte film is produced by graft-polymerizing either a polymerizable monomer having an alkoxysilyl group alone or the polymerizable monomer having an alkoxysilyl group and another polymerizable monomer with a resin film which has been irradiated with a radiation, followed by hydrolyzing the alkoxysilyl groups to conduct dehydrating condensation. In addition, this solid polyelectrolyte film is disposed between a fuel electrode and an air electrode to fabricate a fuel cell.

摘要： An electron beam system for treating filamentary workpieces includes an electron beam irradiation chamber having openings through which passes a filamentary workpiece, an electron beam generator including means for generating, accelerating and focusing electrons, and a communicating section which connects the electron beam generator with the electron beam irradiation chamber. The system also has a differential evacuating means for holding the pressure within the electron beam generator below that within the electron beam irradiation chamber. Electrons are generated, accelerated, and focused by the electron beam generator into a beam which passes from the generator through the communicating section to the electron beam irradiation chamber where the beam is directed at a filamentary workpiece. The system is able to uniformly, efficiently, and continuously apply electron beam irradiation to a traveling filamentary workpiece. When used in the fabrication of optical fiber, this system can accommodate higher fiber drawing speeds without compromising the transmission characteristics of the resulting optical fiber.

摘要： A novel ceramic electrostatic chuck with built-in heater is proposed which is outstandingly durable in use with repeated cycles of heating and cooling because of the absence of troubles due to exfoliation of layers and crack formation in the ceramic body. Differently from conventional ceramic electrostatic chuck with built-in heater consisting of a base plate of sintered body of boron nitride, layers of pyrolytic graphite formed on the surfaces of the base plate to serve, one, as the electrode layer and, the other, as the heater element, and an insulating layer of pyrolytic boron nitride formed on the pyrolytic graphite layers, the base plate in the invention is made of a composite sintered body of a powder mixture of aluminum and boron nitrides in a specified mixing proportion so as to minimize the difference in the thermal expansion coefficient from those of the overlaying layers.
