| Abstract | The scanning electron microscopic studies of the clay minerals have usually been made on air-dried samples. The air-drying method is, however, not always preferable for H(2)O rich clay minerals such as imogolite because of their strong contraction in the dehydration process. The present writers examined the critical point drying for H(2)O rich clay mineral (imogolite) and proved that this drying method is excellent in preservation of natural surface of the minerals than that of air-drying. Imogolite which examined was separated from Kurayoshi pumice beds. The samples were treated first with OsO(4) solution and then were dehydrated progressively with ethanol. After completing above treatments, the imogolites which sealed in vessel were dried successively at critical point of CO(2). The samples were mounted onto brass stubs and coated first with carbon and then with Au-Pd alloy. The Japan Electron Optics Laboratory Co. scanning electron microscope Model JSM-50A which was installed in the Division of Rehabilitation Medicine in the present Institute was used at the operating conditions: accelerating voltage 25kV, magnifications ranging from 3000 to 40000. The scanning electron micrographs of the air-dried imogolite are shown in plate I, and cry tical point dried ones are in plate II and III. The former shows twig-like shape which indicated the effect of contractility, whereas the latter exhibits softly curled and entangled threads. The diameter of these threads ranges from 280A to 560A. |

| Abstract | In this paper, we investigate a light-confinement phenomenon in the structure which has triangular latice composed of Double NeGative Metamaterial (DNGM). In geometrical optics consideration, this structure is expected to confine lights completely by sequential refractions in the structure. We demonstrate it by using the two dimensional finite-difference time-domain simulations. We introduce Drude-Lorentz model for dielectric and magnetic dispersion of the material at optical frequencies. We analyze quantitatively the effects of energy loss in the DNGM on the light-confinement efficiency. |

| Abstract | In this paper, we propose the method to determine the position of the 2 cameras for the multiviewpoints as the robot is the work place. The optical axit's direction of the 1st camera is determined in the base ot work contents in teleoperation. The multiviewpoints system uses the 2 camera units that aren't installed side by side, so that the direction of the 2nd camera is decided in the base of the angle between the optical axes' direction of 2 cameras. Next, the distance from the camera to the work place is determined according to the distance resolution of image on the monitor, and the camera type of which the point-blank range is not this distance is selected. And the efficacy ot this system is examined with an experiment. |

| Abstract | Metamaterial which has negative permittivity and permeability is investigated via computer simulations. Effects of the nanostructure on dielectric and magnetic properties of the material are taken into account by introducing the Drude-Lorentz model in the materials dispersion. We include multi-band process in the dielectric response in order to reproduce accurately experimental values of bulk Au thin film. Size effect on the dispersion is examined by comparing the model with that of a noble metal particle. Based on the dispersion model constructed, we analyze the electromagnetic response of nanostructured metamaterials to evanescent waves at microwave and optical frequencies via finite-difference time-domain simulatioins on parallel computer. A re- focusing and an amplification of the evanescent waves propagating through a metamaterial, consisting of metal slab/vacuum stacking, is demonstrated for the frequencies of 30GHz and 744THz. |
