  • Publication number: 20190011478
    Abstract: An observation method using a compound microscope of an inverted optical microscope and an atomic force microscope includes scanning a cantilever so that a probe approaches a sample until surface layer information is acquired, observing the cantilever through the optical microscope to acquire shape information of the cantilever, moving an observation position of the optical microscope downward based on a length of the probe, performing fluorescence observation through the optical microscope, and scanning the cantilever to acquire the surface layer information. The probe approach, cantilever observation, and observation position movement are performed in order. The fluorescence observation is performed after the observation position movement. The surface layer information acquisition is performed after the probe approach.

  • Patent number: 10161959
    Abstract: An atomic force microscope acquires sample information by performing relative raster scanning between a cantilever and a sample across an XY-plane, while causing an interaction to be generated between a probe provided at a free end of the cantilever and the sample. The atomic force microscope includes a raster-scanning-information generator to generate raster scanning information, a raster-scanning controller to control the raster scanning based on the raster scanning information, and an interaction controller to control strength of the interaction based on the raster scanning information. The interaction controller relatively reduces the strength of the interaction, when a relative speed between the cantilever and the sample across the XY-plane of the raster scanning relatively decreases.

  • Patent number: 10107833
    Abstract: An atomic force microscope is to acquire sample information by a raster scanning of a cantilever with respect to a sample. The atomic force microscope includes a raster-scanning-information generator to generate raster scanning information including timing information. The timing information includes a first timing at which a relative speed between the cantilever and sample decreases lower than a threshold, and a second timing at which the relative speed increases higher than the threshold after the first timing. The atomic force microscope also includes a raster-scanning controller to control the raster scanning, and an interaction controller to decrease the strength of an interaction between the cantilever and sample at the first timing, and increase the strength of the interaction at the second timing.

  • Patent number: 9968017
    Abstract: An electromagnetic shielding tube has a resin inner layer as the innermost layer, a resin outer layer as the outermost layer, and a metal metal-layer between the inner layer and the outer layer. The bonding strength between the outer layer and the metal layer is made weaker with respect to the bonding strength between the inner layer and the metal layer. For example, while an adhesive layer is provided between the inner layer and the metal layer, the outer layer can be directly extrusion coated onto the metal layer without providing an adhesive layer or the like between the outer layer and the metal layer.
