Optical pulses emitted from an optical pulse source is incident on a living tissue and is input to an optical sampling unit. An optical sampling unit detects intensities, f, of optical pulses detected at the respective timings of trigger signals input from a delay unit. A first accumulator calculates products, t.multidot.f, of the intensities f and the delay times t from the delay unit. A second accumulator accumulates the light intensities f. An average optical pathlength calculating unit calculates an average optical pathlength using the accumulation results as the products t.multidot.f and the intensities f. An SO.sub.2 value calculating unit calculates a ratio of V.sub.HbO2 to V.sub.Hb from the average optical pathlength to calculate an SO.sub.2 value.

A carbon composite material reinforced with a carbon fiber and an inorganic fiber. The composite material has a core formed of a carbon fiber-reinforced carbon composite comprising a carbon fiber reinforcement and a carbon matrix, The core is externally covered with an inorganic fiber-reinforced carbon composite comprising an inorganic fiber reinforcement, other than carbon, and a matrix composed either of carbon alone or a mixture of carbon and boride. This provides for sound and steady protection against oxidation, as well as for retention of high strength in an oxidizing atmosphere at high temperatures.

The invention relates to a press cylinder for a high-temperature, high-pressure pressing machine for use in sinter molding ceramics, hard metals, and the like. An outer casing constructed of a carbon fiber reinforced carbon composite and an inner casing constructed of a heat resistant material are fitted together. The inner casing is formed with a longitudinally extending slit which meets given conditions. A gap which meets given conditions is formed between the outer casing and the inner casing. Because of the presence of the slit and the gap, no substantial stress is liable to be exerted on the outer and inner casings which are different in thermal expansion coefficient. Therefore, the outer and inner casing are not liable to fracture or plastic deformation.

The present invention provides a method of quickly and accurately detecting and/or assaying an antigen using fluorescence correlation spectroscopy (FCS), which involves a fluorescence-labeled antibody fragment and a non-fluorescence-labeled intact antibody that form a complex with the antigen. There is a significant difference in diffusion rate between the fluorescence-labeled antibody fragment not bonded to the antigen and the complex formed by the the fluorescence-labeled antibody fragment, the antigen, and the non-fluorescence-labeled intact antibody, and this diffusion rate can be determined using FCS. The antigen can be an antigenic protein, such as an abnormal prion or a harmful protein contained in a food material. According to this method, antigens over a wide scope can be assayed regardless of the shape or molecular weight.

An endoscope apparatus and method are disclosed wherein first and second light beams, each having different center wavelengths, illuminate an object. A detector and a light receiver optical system are provided that receive back-scattered light from first and second illumination devices. A processor is provided that calculates a value corresponding to the size of particles that back-scatter light of the first and second light beams that are incident onto the object, with the calculated value being independent of the concentration of the particles. The first illumination device and the second illumination device are arranged in a specified manner so that a specified condition is satisfied.

摘要:
The present invention is to provide a method of quickly detecting an antigen at an arbitrary concentration in an antigen sample, without a multi-stage examination of the concentration ratio between a detection reagent and an antigen to be detected, particularly when the concentration of the antigen in the sample is unknown, in the method of detecting an antigen using fluorescence correlation spectroscopy (FCS) or fluorescence cross-correlation spectroscopy (FCCS). By preparing (1) a series to which only a detection reagent is added and (2) a series to which an antigen and the detection reagent are added to achieve a maximum trimer concentration, and by performing a fluorescence spectroscopic analysis, the presence or absence of the antigen in the detection sample is quickly detected by the presence or absence of a trimer detection signal from a detector in the cases of (1) and (2), in a method of detecting an antigen by FCS or FCCS using as a detection reagent a fluorescent-labeled intact antibody or fluorescent-labeled antibody fragment targeted to an epitope of the antigen to be detected, and a non-fluorescent-labeled intact antibody or fluorescent-labeled intact antibody or fluorescent-labeled antibody fragment targeted to another epitope of the antigen.
