摘要:
Measurement data of intensities of fluorescence obtained by directing excitation light onto a subject is acquired. An initial value of an absorption coefficient of the phosphor is set on the basis of a concentration distribution of the phosphor, an intensity distribution of the fluorescence on the basis of an absorption coefficient and a diffusion coefficient (reduced scattering coefficient) of the subject, which are set beforehand, are calculated, and the measurement data is compared with the calculation result. If these are found not to be matched, an absorption coefficient of the phosphor at which the error will be a minimum is estimated by performing an inverse problem calculation using a mathematical model. The calculation of the intensity distribution of the fluorescence and evaluation of the error from the obtained concentration distribution are repeated using the absorption coefficient, and a concentration distribution for which the error is the minimum is acquired.

Reference data are subtracted from corresponding actual measurement data, and unprocessed binding quantity data, each of which represents a quantity of binding of a ligand and each of analytes, are thereby acquired. Calculation is made to find a relationship between the reference data and the unprocessed binding quantity data acquired in cases where the binding does not occur. In accordance with the relationship, variation components, which are contained in the unprocessed binding quantity data, are calculated. The variation components are subtracted from the corresponding unprocessed binding quantity data, and processed binding quantity data are thereby acquired. The processed binding quantity data are utilized for extracting an analyte capable of binding with the ligand.

A pickup device includes a diffraction grating 12 for separating a light beam emitted from the light source into at least three light beams. The diffraction grating 12 is divided into four regions by straight lines extending in a direction parallel to a tangential direction of tracks of an optical information recording medium. A periodic structure of a second region 12B has a phase difference of approximately 180 degrees from a periodic structure of a third region 12C, and a periodic structure of a first region 12A has a phase difference of approximately 180 degrees from a periodic structure of a fourth region 12D.

A commutator having a plurality of segments, a short-circuit member assembly, a holding portion, and a plurality of spacing members is disclosed. The short-circuit member assembly includes a plurality of short-circuit pieces. Each short-circuit piece has an outer terminal, an inner terminal arranged radially inward from the outer terminal and circumferentially offset from the outer terminal at a predetermined offset angle, and a connecting portion connecting the inner terminal to the outer terminal. The holding portion covers the segments and at least a portion of the short-circuit member assembly to hold the segments and the short-circuit member assembly. The spacing members each have an insulated support portion and a plurality of insulated spacing projections formed integrally with the support portion. Each support portion extends in a radial direction of the short-circuit member assembly. The spacing projections are arranged in the direction in which the corresponding support members extend in such a manner that the spacing projections are each provided between the corresponding circumferentially adjacent pair of the connecting portions.

The invention presents an optical element with which an optical head can be configured, in which there is little deterioration of the correctional effect when the objective lens shifts, as well as an optical head and an optical recording/reproducing apparatus using such an optical element. The invention also presents a novel optical recording/reproducing apparatus and optical recording/reproducing method. The optical element, includes a first voltage application electrode 13, a first opposing electrode 17 arranged in opposition to the first voltage application electrode 13, and a first phase changing layer 15 arranged between the first voltage application electrode 13 and the first opposing electrode 17. By changing a voltage between the first voltage application electrode 13 and the first opposing electrode 17, a phase that converts plane waves into spherical waves is imparted on light that is incident on the first phase changing layer 15.

A plural color component film laminate part and method for insert-molding a plural color film laminate part comprises preforming a film laminate and subsequently insert-molding a plastic substrate against the preformed film laminate. An improvement in traditional insert molding techniques is provided by use of a specific mold cavity structure which facilitates positioning of the film laminate transition line(s) between colors within longitudinally extending groove(s) in the part show face. According to one embodiment, the film laminate is preformed with a re-entrant edge portion which is positioned within the mold cavity such that the edge of the plastic substrate will be substantially covered. The insert molding step involves positioning the preformed film laminate in a specially configured mold cavity, closing the mold and injecting molten resin into the mold' cavity against the film laminate.

An object of the present invention is to acquire optimum recording characteristics of an optical recoding medium having multiple data layers, with respect to each of the multiple data layers without increasing learning time required for learning a relation between aberration amount and optimum recording compensation with respect to each of the multiple data layers. The present invention includes a wavefront converter which is driven in such a manner as to reduce the aberration amount detected by an aberration detector. An output controller holds learned data as to the relation between the driving amount of the wavefront converter and the output of a light source, and controls the output of the light source based on the driving amount of the wavefront converter and the learned data.
摘要:
A weight 4 which is held by a weight holder 3 in a balancer has a pressing face 4b′ which is pressed against a guide face 12a provided along the circumferential direction of rotation of the weight holder 3 by centrifugal force generated by rotation of a rotary body. When the rotary body rotates, the weight 4 which is pressed against the guide face 12a via the pressing face 4b′ changes its position relative to the rotary body in the circumferential direction of rotation, whereby the weight 4 is disposed in a position in which it suppresses whirling motion of the rotary body. The guide face 12a and pressing face 4b′ are inclined relative to the axial direction of rotation so as to tend to outward side in the diametrical direction of rotation as tending to one side in the axial direction of rotation. The weight 4 is pressed against a receiving portion 7a′ by component of the centrifugal force, in which the component acts along the guide face 12a and pressing face 4b′.
