Patent number: 7037727Abstract: An apparatus for measuring a medical substance where a prism having a high refractive index, a thin metal film formed on one of the surfaces of the prism, a light source for making a light incident upon the thin metal film, and a detector for detecting an incident angle of a light being made incident upon a film on which a plasmon resonance phenomenon is generated on the thin metal film are provided. The medical substance, i.e. antigen as an object to be measured, is fixed to the surface of the thin metal film, and the condition for generating the plasmon resonance phenomenon is varied when a mixture of antibody which is coupled with the medical substance in a specific manner and a sample is made contact with a surface of the thin metal film; and the amount of the medical substance can be detected by recognizing the change with a high sensitivity.Type: GrantFiled: December 4, 1997Date of Patent: May 2, 2006Assignee: DKK CorporationInventors: Norio Miura, Noboru Yamazoe, Taizo Uda

Patent number: 4718991Abstract: A proton conductor gas sensor operable at room temperature for detecting hydrogen or carbon monoxide, and a gas detecting method using the sensor. A pair of electrodes connected to a proton conductor are short-circuited to cause protons to travel through the conductor utilizing the difference in activity between the electrodes or the difference in gas permeability between the electrode and an atmosphere containing the gas to be detected. The potential difference produced in the interior of the conductor by the travel of the protons is obtained as the output of the sensor. This output is in proportion to the concentration of the gas and low in humidity dependence.Type: GrantFiled: January 20, 1987Date of Patent: January 12, 1988Assignee: Figaro Engineering Inc.Inventors: Noboru Yamazoe, Norio Miura
