Patent number: 9297799Abstract: The present invention provides a method for measuring oocyst of protozoa, such as Cryptosporidium, in an environment sample with high sensitivity at low cost within a short period of time; and a detecting reagent for use therein. Magnetic fine particles of 5 to 500 nm particle diameter having, immobilized thereto, binding factors for specific recognition of oocyst are added to an analyte containing a protozoan oocyst to form oocyst/binding factor/magnetic fine particle complexes by using a binding reaction to the oocyst, the formed complexes are recovered by a magnetic separation, and the protozoan oocysts contained in the complexes are assayed. Further, there is provided, for conducting the above method, a reagent for detecting protozoan oocysts comprising magnetic fine particles of 5 to 500 nm particle diameter having, immobilized thereto, antibodies against oocysts or binding factors for recognizing the antibodies.Type: GrantFiled: January 11, 2006Date of Patent: March 29, 2016Assignees: NATIONAL UNIVERSITY CORPORATION KOBE UNIVERSITY, JNC CORPORATIONInventors: Noriyuki Ohnishi, Hirotaka Furukawa, Hideyuki Hata, Kageaki Matsui, Takako Nogami, Hideo Nishizawa, Akihiko Kondo

Publication number: 20050275714Abstract: An eyeglass interface device includes a camera section, a wireless communication section, and a power generation section. The camera section acquires the image of the retina of an eyeball of a user, and outputs the imaging signal thereof to the wireless communication section. The wireless communication section transmits the imaging signal from the camera section by a radio wave. The power generation section supplies power to the camera section and the wireless communication section. The eyeglass interface device preferably includes a display section for displaying, on eyeglass lenses, image information sent from a mobile phone or the like to the wireless communication section, and an audio section having a bone conduction earphone and a microphone.Type: ApplicationFiled: June 6, 2005Publication date: December 15, 2005Inventors: Yohei Ishikawa, Hideo Nishizawa, Masafumi Goto

Patent number: 6033572Abstract: Selenium-containing wastewater is sequentially treated through use of biological treatment means (6), chemical treatment means (12), and filtration means (14). In the biological treatment means (6), raw waste water (16) is subjected to anaerobic biological treatment so as to reduce selenate ions and/or selenite ions (soluble selenium) present in the raw waste water (16) to simple selenium, which is insoluble, to thereby remove the selenate ions and/or the selenite ions in the form of insoluble simple selenium. In the chemical treatment means (12), for example, a metal salt that reacts with soluble selenium to form an insoluble selenium compound is added to water treated by the biological treatment means (6), to thereby remove residual soluble selenium in the form of the insoluble selenium compound. In the filtration means (14), an insoluble substance remaining in water treated by the chemical treatment means (12) is removed through filtration.Type: GrantFiled: January 15, 1999Date of Patent: March 7, 2000Assignee: Organo CorporationInventors: Rie Yano, Hideo Nishizawa
