    摘要: Sample drift in a scanning electron microscope is suppressed which is caused by a change in room temperature or associated with operation of motors for driving a sample stage. Supply currents to the motors during movement of the sample and a stop of the sample movement are controlled so that the supply currents have the same level or so that a maximum difference in level between the supply currents is 20%. This lessens any changes in the amounts of heat generated by the motors, thereby reducing sample drift during observation.

    摘要: An object of the present invention is to provide a solid polymer electrolyte membrane in which a polyazole-based compound is uniformly mixed with a perfluorocarbonsulfonic acid resin. Thus, the present invention provides a solid polymer electrolyte membrane for solid polymer electrolyte fuel cell, which has high durability, as well as a membrane electrode assembly and a solid polymer electrolyte fuel cell, each containing the same. The inventive solid polymer electrolyte membrane is produced by a method which comprises a polymer electrolyte-containing solution preparation step of dissolving a perfluorocarbonsulfonic acid resin (component A) having an ion-exchange capacity of 0.5 to 3.0 meq/g, a polyazole-based compound (component B) and an alkali metal hydroxide in a protic solvent to prepare a polymer electrolyte-containing solution in which a weight ratio of the component A to component B, (A/B), is from 2.3 to 199 and a total weight of the component A and the component B is from 0.5 to 30% by weight; and a membrane formation step of forming a membrane from the polymer electrolyte-containing solution.

    摘要: A stage comprises a linear guide rail (2) for guiding a movable table (4), a driven bar (12), a linear drive actuator in contact with the driven bar (12) to transmit driving force to the driven bar (12), and parallel plate springs (30) for holding opposite ends of the driven bar (12). A drive transmitting surface of the linear drive actuator is provided so as to be separated from the movable table (4), and this prevents the accuracy of positioning from being reduced. Also, the parallel springs (30) reduce deforming forces applied to sections supporting the driven bar (12), and this prevents the driven bar from being damaged. The configuration makes the stage highly accurate and highly reliable.

    摘要: A polymer electrolyte-containing solution is obtained by preparing a first solution, preparing a second solution and mixing the first and second solutions. The first solution is prepared by dissolving a perfluorocarbonsulfonic acid resin (component A) having an ion-exchange capacity of 0.5 to 3.0 meq/g in a protic solvent. The second solution is prepared separate from the first solution, by dissolving a polyazole-based compound (component B) and an alkali metal hydroxide in a protic solvent. The first and second solutions are mixed to prepare a polymer electrolyte-containing solution in which a weight ratio of the component A to component B, (A/B) , is from 2:3 to 199 and a total weight of the component A and the component B is from 0.5 to 30% by weight on the basis of the solution including the protic solvent. The protic solvent is an aliphatic alcohol.
