Abstract: Provided is a fetal heart rate variability monitoring device capable of easily determining a fetal condition. A fetal heart rate variability monitoring device includes a processing unit and a display unit that acquire a fetal heart rate and display a fetal heart rate diagram showing the fetal heart rate over time, an LTV and STV conversion processing unit that calculates STV and LTV from the fetal heart rate, and an event input unit that can designate a predetermined period on the fetal heart rate diagram. The processing unit and the display unit have a function of issuing notification of the STV and LTV in the predetermined period calculated by the LTV and STV conversion processing unit when the predetermined period is designated by the event input unit.

Abstract: An image display apparatus according to an aspect of the present technology includes a light source, an image generator, and a projection optical system. The image generator modulates light emitted from the light source and generates image light. The projection optical system includes a lens system and a concave reflective surface. The lens system is configured on a basis of a reference axis at a position on which the generated image light is incident, and has a positive refracting power as a whole. The concave reflective surface is configured on a basis of the reference axis, and reflects the image light emitted from the lens system toward a projection target. In addition, the concave reflective surface reflects at least one or more light beams included in the image light incident on the concave reflective surface, toward a direction that intersects with a direction along the reference axis at an angle of 80 degrees or more.

Abstract: An object of the present invention is to enable to accurately quantify HBs antigen in the samples for which measured values are low or false-negative results by the conventional assaying method of HBs antigen. In the method of assaying HBs antigen according to the present invention, at least one inner capture probe that binds to a first inner region peptide consisting of 26th to 80th amino acid residues of HBs antigen and at least one outer capture probe that binds to a second outer region peptide consisting of 98th to 156th amino acid residues of HBs antigen are used as capture probes; and at least one inner detection probe which binds to the first inner region and at least one outer detection probe which binds to the second outer region are used as detection probes.

Abstract: A lens barrel includes: a lens holding frame holding a lens; a mounting member to which the lens holding frame is mounted; an inclination regulating member regulating a position of the lens holding frame with respect to the mounting member, thereby regulating inclination of the lens holding frame with respect to an optical axis; and an eccentricity regulating member regulating the position of the lens holding frame with respect to said mounting member, thereby regulating eccentricity of the lens holding frame with respect to the optical axis, in which the eccentricity regulating member is supported by said inclination regulating member.

Abstract: A method of treating samples containing hepatitis C virus (HCV) which method comprises treating HCV-containing samples with a treating agent containing (1) an acidifying agent, and (2) a protein-denaturing agent, or an amphoteric surfactant or a cationic surfactant having both a straight chain alkyl group of 10 or more carbon atoms and a tertiary amine or a quaternary ammonium salt in the same molecule, to effect the release of the HCV antigen and the inactivation of antibodies that bind to the HCV antigen, and the like.

Abstract: A lens drive mechanism includes: a lens holding frame that holds a lens and has a guided portion and a nut support; a nut member so supported by the nut support that the nut member pivotally moves around an optical axis of the lens; a lead screw that engages with the nut member and rotates around an axis of the lead screw to move the lens holding frame; and a guide unit that is inserted into the guided portion of the lens holding frame and guides the lens holding frame in the optical axis direction when the lead screw rotates and moves the lens holding frame. The guide unit, the lead screw, and the lens holding frame are accommodated in and attached to a lens barrel housing having an insertion opening, and the lens holding frame is inserted through the insertion opening and accommodated in the lens barrel housing.

Abstract: [PROBLEMS] To provide a soluble highly sensitive probe complex with high functional capability ensuring usability in immunoassays of high sensitivity. [MEANS FOR SOLVING PROBLEMS] A highly sensitive probe complex can be produced by linking hydrophilic intermediums to a carrier and linking detection markers such as biotin, haptens or low-molecular-weight peptides and antibodies to the intermediums. By virtue of the linking of hydrophilic intermediums to a carrier, a multiplicity of hapten molecules can be linked and the probe complex as a whole becomes hydrophilic, so that there can be obtained a probe complex with high functional capability which would not induce nonspecific reactions.
