    摘要: An eye refractometer is provided with a projection optical system for projecting test beams forming test patterns such that the central ray of each test beam passes through the pupil of the eye to be inspected while being spaced apart from the optic axis in order to form test patterns corresponding to three meridians forming 60.degree. with each, a focusing lens disposed in the projection optical system and movable only in one direction during one measurement, and a beam detecting device for detecting the reflected images of the test patterns by the retina of the eye and generating electrical signals corresponding to the three meridians.

    摘要: A method and system of velocity control for an automatic welding apparatus, wherein at least either a welding torch or a workpiece is movable in the directions of the three rectangular axes and point-to-point (PTP) position control of the torch and workpiece is effected between two preset positions at a preset relative velocity. In effecting the PTP position control, the direction of movement is determined based on information about the two preset positions, and the components of the preset velocity in the directions of the three rectangular axes are determined based on the direction of movement thus found and also based on information about the preset velocity, these components being used as instruction velocities in the respective axes.

    摘要: An R-cut substrate is prepared by cutting lumbered synthetic quartz crystal along a surface parallel to the R-face. The surface of the thus obtained R-cut substrate has a structure in which the R-face smoothest in terms of the crystal structure accounts for the most part of the surface, and the m- and r-faces are exposed on this surface to extend in a direction parallel to the X-axis albeit only slightly upon processing. After catalytic metals are arranged on the surface of the R-cut substrate, a carbon source gas is supplied onto the surface of the R-cut substrate to grow carbon nanotubes in accordance with the crystal lattice structure using the crystal metals as nuclei. This makes it possible to manufacture carbon nanotubes with a good orientation and linearity.

    摘要: The invention provides a composite comprising a substrate and a membrane of vertically aligned carbon nanotubes formed on the substrate which membrane is independent of the material of the substrate and a process for the production of the same. A process for producing the first composite comprising the first substrate and vertically aligned carbon nanotubes formed on the first substrate which comprises the step (a) of preparing the second composite comprising the second substrate made of quartz or silicon and vertically aligned carbon nanotubes formed on the second substrate, the step (b) of subjecting the second composite to water immersion wherein the temperature (Tw) of the water is higher than the temperature (Tc) of the second composite with a temperature difference ΔT (=Tw−Tc) of at least 25° C. to make the carbon nanotubes peel off the second substrate and arrange them either in water or on the surface thereof, and the step (c) of arranging the resulting vertically aligned carbon nanotubes on the first substrate.
