Patent number: 8435449Abstract: A chemical substance sensing element 142 for detecting a specific chemical substance included in biological information includes a carbon nanostructure and, because of metal complex or a fluorescent molecule modifying its surface, exhibits substance selectivity and high sensitivity. Of the substances modifying the surface of carbon nanostructures, CoPc reacts with NO and pentane and DAF-2 reacts with NO, as the components contained in the biological information, respectively, and both produce reaction products. The reaction product derived from CoPc changes electric resistance between nodes 154 and 156, and the reaction product derived from DAF-2 generates fluorescence of a specific wavelength when irradiated with excitation light. Therefore, by measuring the change in electric resistance or presence/absence and wavelength of fluorescent of the present element, sensing of NO or pentane is possible.Type: GrantFiled: March 4, 2008Date of Patent: May 7, 2013Assignee: Sharp Kabushiki KaishaInventors: Mikihiro Yamanaka, Katsutoshi Takao, Tomohisa Kawata, Norie Matsui, Shuhji Nishiura, Keita Hara, Yasuaki Murashi, Jun Kudo

Publication number: 20120315666Abstract: In a detection apparatus, an inlet and an outlet are opened and an air introducing mechanism is driven to introduce air to a case, and airborne particles are electrically attracted and held on a collecting jig 12. After introduction, the inlet and outlet are closed, and amount of fluorescence received by a light receiving element resulting from irradiation with light emitted from a light emitting element is measured by a measuring unit. Thereafter, the collecting jig is heated by a heater and the amount of fluorescence after heating is measured by the measuring unit. Based on the amount of change in the amount of fluorescence before and after heating, the amount of microorganisms collected by the collecting jig is calculated at the measuring unit.Type: ApplicationFiled: July 7, 2010Publication date: December 13, 2012Inventors: Kazushi Fujioka, Kazuo Ban, Norie Matsui, Hiroki Okuno

Publication number: 20120136584Abstract: A light receiving element provides a current signal corresponding to an amount of received light scattered by suspended particles moving at a predetermined speed to a pulse width measurement circuit and a current-voltage conversion circuit via a filter circuit. A pulse width measured from the current signal is converted into a voltage value based on a predetermined relationship by a pulse width-voltage conversion circuit, and is provided to a voltage comparison circuit. The current-voltage conversion circuit converts a peak value of the current signal into a voltage value, and an amplifier circuit amplifies the signal at a predetermined amplification factor and provides the same to the voltage comparison circuit. The voltage comparison circuit uses the voltage value converted from the pulse width as a boundary value, and the suspended particles causing the scattered light are detected as microorganisms when the peak voltage value is smaller than the boundary value.Type: ApplicationFiled: July 26, 2010Publication date: May 31, 2012Inventors: Kazuo Ban, Kazushi Fujioka, Norie Matsui, Shuhji Nishiura, Hiroki Okuno, Katsutoshi Takao

Patent number: 7426168Abstract: The present invention discloses a hologram erasing method, in which a predetermined hologram is erased by irradiating a predetermined region of a hologram recording medium in which the hologram to be erased is recorded with a reference light beam and a signal light beam holding a random data pattern at the same time. In this method, the signal light beam and the reference light beam interfere with each other in the medium, and a Fourier transform hologram recorded in the region where the interference occurs is destroyed and erased by interference light beam. That is, a data page for erasing including a random pattern is overwritten to erase an original data page. According to the present invention, the hologram recorded in the optical recording medium can be selectively and completely erased in a simple method.Type: GrantFiled: February 23, 2004Date of Patent: September 16, 2008Assignee: Fuji Xerox Co., Ltd.Inventors: Katsunori Kawano, Jiro Minabe, Shin Yasuda, Tatsuya Maruyama, Norie Matsui

Patent number: 7319550Abstract: While Fourier transformation of a signal light beam is performed to perform recording during holographic recording so that a focal point is formed outside a holographic recording layer (defocus recording), an aperture is arranged on an outgoing side of the reproduced signal light beam (reproduction light beam), the reproduction light beam is focused at the aperture, and low-order components of a Fourier transform image of the reproduction light beam are selectively transmitted to detect only the transmitted light beam. Therefore, information recorded as the hologram in the holographic recording layer can be reproduced with high S/N ratio from the holographic recording layer added onto a support body, particularly onto a sheet member having non-optical quality such as paper and a plastic card.Type: GrantFiled: December 8, 2004Date of Patent: January 15, 2008Assignee: Fuji Xerox Co., Ltd.Inventors: Kazuhiro Hayashi, Katsunori Kawano, Yasuhiro Ogasawara, Jiro Minabe, Shin Yasuda, Hisae Yoshizawa, Norie Matsui

Patent number: 7307768Abstract: A hologram is recorded by irradiating, with a reference light beam, a region corresponding to an intensity distribution of a signal light beam on an optical recording medium. For example, the reference light beam having the intensity distribution which substantially coincides with the intensity distribution of the signal light beam is generated, and only the region which substantially coincides with the region irradiated by the signal light beam (i.e., the signal light beam defocused region) is irradiated with the reference light beam. This enables only the necessary region to be exposed and the regions which need not be exposed not to be exposed. Accordingly, the hologram can be recorded without losing information of the signal light beam and thus high-density recording can be realized.Type: GrantFiled: February 23, 2004Date of Patent: December 11, 2007Assignee: Fuji Xerox Co., Ltd.Inventors: Katsunori Kawano, Jiro Minabe, Shin Yasuda, Tatsuya Maruyama, Norie Matsui

Patent number: 7154646Abstract: An optical recording/reproducing apparatus having excellent resistance against vibration and noise. In recording, coherent light is polarization-modulated with a spatial light modulator to generate signal light and reference light whose polarization directions are crossed at right angles. The signal light permeates a polarizing beam splitter, and is incident to a quarter wavelength plate. The reference light passes through a passing hole, is diffused by a light diffuser and is incident to the quarter wavelength plate. The reference and signal light are converted into circularly polarized light which revolve in directions opposite to each other and condensed by a condenser lens, and then a predetermined area of an optical recording medium is irradiated with the reference and signal light. Thus, the reference and signal light are generated by modulating the incident light from the same light source and are coaxially incident to the polarizing beam splitter.Type: GrantFiled: April 27, 2006Date of Patent: December 26, 2006Assignee: Fuji Xerox Co., Ltd.Inventors: Katsunori Kawano, Jiro Minabe, Tatsuya Maruyama, Shin Yasuda, Norie Matsui, Tsutomu Ishii, Kazuhiro Hama

Patent number: 7083128Abstract: A shredder that shreds a recording medium which includes, on a surface thereof, an image forming portion and a holographic memory portion in which data is recorded. The shredder includes a data destroying unit that destroys at least the data recorded in the holographic memory portion and a shredding unit that shreds the entire recording medium. Thus, when a recording medium to which has been added a holographic memory portion in which useful information is recorded is to be discarded, the data(information) recorded in the holographic memory portion can be safely destroyed so that the data can no longer be read.Type: GrantFiled: August 25, 2004Date of Patent: August 1, 2006Assignee: Fuji Xerox Co., Ltd.Inventors: Hisae Yoshizawa, Katsunori Kawano, Jiro Minabe, Kazuhiro Hayashi, Yasuhiro Ogasawara, Shin Yasuda, Norie Matsui
