摘要:
A drive apparatus for a liquid crystal dazzlement preventing mirror arrangement for automatically setting a liquid crystal panel of the mirror arrangment to a dazzlement preventing state by detecting illuminance on the mirror surface and brightness in region near the mirror. An incident light detecting unit detects incident light onto the mirror. An ambient light detecting unit detects brightness in a region around mirror. A control unit receives both the incident light and the ambient light signals and produces a control signal for driving the liquid crystal panel through a drive unit. The apparatus includes an illuminance descrimination function, which is performed in such a manner that in the event of the illuminance on the mirror surface is higher than first prescribed set value of incident light illuminance and the illuminance in region around the mirror is lower than a prescribed set value of ambient light illuminance, the dazzlement preventing state is provided, and that in the event of the incident light illuminance is higher than a second prescribed set value of incident light illuminance which is higher than that of the first set value, irrespective of the ambient light illuminance, the dazzlement preventing state is also provided.

This invention discloses a glare-shielding reflector which controls light reflectance electrically. The present invention provides a glare-shielding type reflector having a photosensor block which can detect an incident angle of a luminous flux to the reflector and a glare-shielding layer which is divided into plural units and driven individually. A glare-shielding layer formed on a front surface of a mirror is divided into plural units and only the specified glare-shielding units are automatically put into a glare-shielding state, according to the incident angle of the luminous flux to the mirror.

An imaging unit includes a mount unit, an imaging element unit, a plurality of elastic members, a plurality of adjusting screws, and at least one restricting member. The mount unit is configured to support the interchangeable lens unit. The imaging element unit is disposed apart from the mount unit and is configured to produce image data for the subject by opto-electrical conversion. The plurality of elastic members is disposed in a compressed state between the mount unit and the imaging element unit. The plurality of adjusting screws is mounted to the mount unit and/or the imaging element unit to adjust the distance between the mount unit and the imaging element unit. The restricting member is mounted to the mount unit and/or the imaging element unit and configured to restrict the imaging element unit from moving close to the mount unit against the elastic force of the elastic members.

Upon producing a transparent polycrystalline material, a suspension liquid (or slurry 1) is prepared, the suspension liquid being made by dispersing a raw-material powder in a solution, the raw-material powder including optically anisotropic single-crystalline particles to which a rare-earth element is added. A formed body is obtained from the suspension liquid by means of carrying out slip casting in a space with a magnetic field applied. On this occasion, while doing a temperature control so that the single-crystalline particles demonstrate predetermined magnetic anisotropy, one of static magnetic fields and rotary magnetic fields is selected in compliance with a direction of an axis of easy magnetization in the single-crystalline particles, and is then applied to them. A transparent polycrystalline material is obtained by sintering the formed body, the transparent polycrystalline material having a polycrystalline structure whose crystal orientation is controlled. In this calcination step, after subjecting the formed body to primary sintering at a temperature of 1,600-1,900 K, the resulting primarily-sintered body undergoes hot-isotropic-press sintering (or HIP processing) at a temperature of 1,600-1,900 K.

There is provided an image processor and a method thereof for high-speed compensation for taken-image blurs produced by camera shakes or the like. In the first instance, a motion-detecting area is selected for each of two images taken by an image sensor. When projective data is calculated by means of computing in a predetermined direction pixels of the motion-detecting areas, the motion vector between the two images can be acquired based on the projective data. The image correlativity between the two images is then calculated in the direction that the motion vector designates; and the amount of pixel displacement between the two images is calculated based on the correlativity values acquired by the calculation. Moreover, the area that has been produced by displacing an image output area in a camera-shake compensation area designated in the second frame, by the pixel-displacement amount calculated by a displacement calculator is cut away from the camera-shake compensation area, and is outputted as an image for the image output area of the second frame.

An ophthalmologic apparatus is disclosed, in which even in the case where the range of lateral relative movement of a trestle is limited with respect to a base, the measurement can be continued without enlarging the space occupied by the apparatus body and without imposing an extra burden on the testee. The apparatus comprises a trestle (4) mounted on a base (3) and laterally movable relative to the base (3) and has a limited range, and a measuring head portion (5) mounted on the trestle (4) and automatically laterally moved relative to the trestle (4) with respect to a reference position (H1). In the case where the trestle (4) moves rightward or leftward and reaches a movement limit position O2, O3, the reference position (H1) of the measuring head portion (5) with respect to the trestle (4) is shifted in the direction in which the trestle (4) moves.
