Patent number: 7884300Abstract: A method of realizing selective separation of metallic single-walled carbon nanotubes and semiconducting carbon nanotubes from bundled carbon nanotubes; and obtaining of metallic single-walled carbon nanotubes separated at high purity through the above method. Metallic single-walled carbon nanotubes are dispersed one by one from bundled carbon nanotubes not only by the use of a difference in interaction with amine between metallic single-walled carbon nanotubes and semiconducting carbon nanotubes due to a difference in electrical properties between metallic single-walled carbon nanotubes and semiconducting carbon nanotubes but also by the use of the fact that an amine is an important factor in SWNTs separation. The thus dispersed carbon nanotubes are subjected to centrifugation, thereby attaining separation from non-dispersed semiconducting carbon nanotubes.Type: GrantFiled: July 29, 2005Date of Patent: February 8, 2011Assignee: University of TsukubaInventors: Takeshi Akasaka, Takatsugu Wakahara, Yutaka Maeda

Patent number: 7539407Abstract: An ornament plate of a ring-shape made of a metal with a high heat radiation effect, for instance, aluminum, is attached to an end surface on an object side of a lens barrel such that the ornament plate covers the whole front part of the lens barrel. Four kinds of LEDs of high luminance type constructing an LED light source are attached to the lens barrel through the ornament plate used as a substrate. A light diffusion cover made of a transparent resin is attached to the front of the ornament plate for covering the LEDs. When using the flash, a high voltage current is applied to the LEDs to emit flash light. Each LED generates heat. However, the heat is radiated through the ornament plate.Type: GrantFiled: November 29, 2005Date of Patent: May 26, 2009Assignee: Fujifilm CorporationInventor: Yutaka Maeda

Patent number: 7460169Abstract: An electronic camera that makes it possible to determine an image-capturing angle of view by displaying a live image on an LCD before a still image-recording even if the object is dark. When the live image is displayed, a cycle for outputting image signals in one field from a CCD can be changed to another cycle; e.g., from a normal video rate of 1/60 second to 1/30 second. Therefore, the exposure time of the CCD can be longer than the normal exposure, and thus, the live image with a suitable brightness can be displayed on the LCD even if the object is dark. The electronic camera is provided with an electronic flash that can be intermittently activated by switching on a switch or automatically if the object is dark before the image recording. This enables the display of the live image with the suitable brightness on the display even if the object is so dark as to require the electronic flash, and the image-capturing angle of view can be determined in view of the live image on the display.Type: GrantFiled: October 6, 2003Date of Patent: December 2, 2008Assignee: Fujifilm CorporationInventor: Yutaka Maeda
