IPC: G01F19/00
Filed: 2004-10-08
Abstract: A method and apparatus for interrogating a sample that exhibits molecular rotation are disclosed. In practicing the method, the sample is placed in a container having both magnetic and electromagnetic shielding, and Gaussian noise is injected into the sample. An electromagnetic time-domain signal composed of sample source radiation superimposed on the injected Guassian noise is detected, and this signal is used to generate a spectral plot that displays, at a selected power setting of the Gaussian noise source, low-frequency spectral components characteristic of the sample in a selected frequency range between DC and 50 kHz. In one embodiment, the spectral plot that is generated is a histogram of stochastic resonance events over the selected frequency range. From this spectrum, one or more low-frequency signal components that are characteristic of the sample being interrogated are identified.

IPC: A61B5/1455
Filed: 2006-05-16
Abstract: A light emission section includes a plurality of light sources and emits near infrared low coherent light beams having different specific wavelengths to a light interference section. The light interference section allows the near infrared low coherent light beams to pass therethrough toward the eyeground and partially reflects the beams toward a movable mirror. Measurement light reflected by the eyeground and reference light reflected by the movable mirror interfere at the light interference section.      Resultant interference light rays propagate to a light detection section, which calculates the profile of the eyeground from the light quantities of the interference light rays, and calculates the oxygen saturation SO2 from the light quantity distributions of the near infrared low coherent light beams emitted from the light emission section and the light quantities of the received interference light rays. A display section displays the calculated profile and oxygen saturation SO2 in a superposed manner.

Title: One-part dental adhesive composition
Inventor: NAKATSUKA KAZUMITSU
IPC: A61K6/00
Filed: 2004-12-08
Abstract: A one-pact type adhesive composition for dental use which is obtained by compounding as essential ingredients a hydrophobic polymerizable monomer (a) having an acid group, a water-soluble polymerizable monomer (b), water (c), a photopolymerization initiator (d), an aromatic tertiary amine (e) having an electron-attracting group, a crosslinking polymerizable monomer (f), and a basic compound (g) which reacts with part of the hydrophobic polymerizable monomer (a) having an acid group to generate a water-soluble salt. The composition has excellent bonding strength in the bonding of a tooth, especially enamel or dentine, to a dental repairing material, especially a resinous material, and has excellent storage stability. Because the composition is of the one-pact type, no mixing operation is necessary in preparation for bonding. Furthermore, the composition has excellent bonding strength even without conducting pretreatments (etching and priming). The composition is hence suitable for use as a one-step type dental adhesive composition for conducting a tooth repair treatment through one bonding operation.
