    摘要: A conductive rotator is immersed in a sample liquid in a sample container. A magnet is arranged at a specific distance from the rotation plane of the rotator in a direction of a rotating axis of the rotator so as to face the sample container. The magnet applies a magnetic field to the rotator from the outside of the sample container. A fluctuating magnetic field drive unit drives the magnet to apply the magnetic field that fluctuates in term of time to the rotator. Induced current is excited in the rotator by the fluctuating magnetic field. A rotating torque is provided to the rotator by the Lorenz interaction between the induced current and the fluctuating magnetic field, and as a result, the rotator rotates in the rotation plane. A viscosity detecting unit obtains the viscosity of the sample liquid based on a rotating state of the rotator and a time-fluctuating state of the fluctuating magnetic field.

    摘要: In order to accurately measure a shape feature of a minute droplet arranged on a substrate by a simple method, with respect to the droplet, the substrate is perpendicularly irradiated with laser light to cause diffracted light fluxes generated during passage of the laser light through the droplet to interfere with each other, so that a diffraction pattern is obtained. The diffraction pattern formed on a screen of a detector as an image is picked up by an image pickup apparatus. The shape feature of the droplet is measured by using the resultant diffraction pattern and a refractive index of the droplet.

    摘要: An optical pickup converts a laser beam from a semiconductor laser (1) into a parallel ray with a collimator lens (2), and divides it into a main beam (30), a sub-beam (+1st order component) (31), and a sub-beam (−1st order component) (32) with a gradient multiple-division type phase difference grating (3). After passing through a beam splitter (4), an objective lens (5) condenses the light beams on a track (61) of an optical disc (6), and the reflected light that has passed through the objective lens 5 is reflected at the beam splitter (4) and is guided into optical detectors (8A, 8B, and 8C) by a condensing lens (7). Accordingly, in a tracking error signal detecting method using the push-pull signals of the main beam and sub-beams, an offset produced by an objective lens shift or a disc tilt can be cancelled at low cost without lowering the efficiency of using light.

    摘要: An objective lens driving apparatus includes a base, an objective lens for converging an optical beam on an optical disc while the optical disc is rotating, and a holding member for holding the objective lens. A first supporting mechanism elastically supports the holding member on the base in such a manner as to allow the holding member to be translated in a focusing direction which is substantially perpendicular to a surface of the optical disc and in a tracking direction which is substantially perpendicular to the focusing direction and parallel to a radial direction of the optical disc. A moving mechanism including a coil and a magnetic circuit translates the holding member in the focusing direction and the tracking direction by a driving force generated by the coil and the magnetic circuit. A second supporting mechanism visco-elastically supports the magnetic circuit on the base in such a manner as to translate the magnetic circuit in the focusing direction. The magnetic circuit is translated in an opposite direction to the translation direction of the holding member by a driving force acting oppositely to the driving force for translating the holding member in the focusing direction.

    摘要: An optical pickup device includes: a splitting section for splitting a beam; a light-receiving section for receiving the split beams. The light-receiving section includes: a tracking-use main light-receiving region and tracking-use sub light-receiving regions, and auxiliary light-receiving regions. Each of the auxiliary light-receiving regions receives only a light beam reflected off a recording layer other than a recording layer subjected to an information writing/reading process. A light-receiving area of each of the auxiliary light-receiving area is smaller than a light-receiving area of each tracking-use light-receiving region. Further, an optical pickup device includes: a splitting section for splitting a beam; and a light-receiving section for receiving the split beams. The light-receiving section includes a sub light-receiving regions for receiving tracking-use sub beams. The tracking-use sub beams are arranged so as not to allow entering of a focusing-use main beam reflected off a non-targeted recording layer.
