An optical apparatus includes: a sealing case having chambers partitioned by a partition wall; a polar liquid having polarity and a nonpolar liquid having no polarity which are respectively sealed in a predetermined amount in each of the chambers; and electrodes pulling the polar liquid by an electrowetting phenomenon upon application of a driving voltage. One of the polar liquid and the nonpolar liquid is colored with a color having a light-blocking property, and the other has a light-transmitting property, at least a part of the partition wall is positioned in an optically effective area including the optical axis, and when a driving voltage is applied to a predetermined electrode among the electrodes, the polar liquid is moved in the chamber between closed and open positions where the optically effective area is closed and open, respectively.

An optical element includes a container including first and second end face walls, a side face wall, and an accommodating chamber inside the walls; first and second liquids enclosed in the chamber; a first electrode provided on a surface of the first end face wall; a second electrode provided on a surface of the second end face wall; an insulating film provided on a surface of the second electrode; and a unit configured to apply a voltage. The shape of an interface between the liquids is changed by a voltage application, and a light transmission path, the center of which is a virtual axis passing through the end face walls in the thickness direction of the container, is formed in a portion of the second liquid. An opening having a diameter the same as or larger than the maximum diameter of the transmission path is provided in the first electrode.

The application relates to an optical device for enhancing the stress to be generated in a substrate in comparison with a conventional technique. To this end, the optical device includes a substrate having a photoelastic effect, a first stress layer formed on a first face of the substrate and having a pattern for generating stress which induces refraction index variation by the photoelastic effect in a partial region in the substrate, and a second stress layer formed on a second face which is a reverse face to the first face of the substrate and configured to generate stress for restoring the shape from the deformation caused by the stress generated in the substrate by the first stress layer in the substrate.

An optical element is disclosed. The optical element may include a container having a holding chamber, a polar or conductive first liquid filled in the holding chamber, a second liquid filled in the holding chamber and not mixing with the first liquid, first and second electrodes for applying an electric field to the first liquid, and voltage application means for applying voltage between the first electrode and the second electrode.

A slide door is provided to be movable between a closed position to cover a side opening formed at a vehicle-body side face and an open position. The slide door is configured to move outward and subsequently slide rearward along a rear vehicle-body outer face when the slide door moves from the closed position to the open position. There is provided a detection sensor to detect a foreign matter in coming into a gap from a vehicle-compartment inside. A drive of the slide door is stopped in case the detection sensor detects the foreign matter in coming into the gap when the slide door moves toward the open position. Thereby, any foreign matter can be prevented from being pinched in the gap formed between the slide door and the rear edge portion of the side opening.

Disclosed is an automobile roof structure, which comprises a pair of right and left roof side rails 1, a transparent roof panel 4 attached to cover a space between the roof side rails 1, a sun shade 5 disposed slidably along a bottom surface of the transparent roof panel 4, and a shade support member 6 for supporting the sun shade 5 in a slidingly movable manner. Each of the roof side rails 1 includes a rail outer panel 7 and a rail inner panel 8 formed, respectively, with roof flanges 14, 15 which are oriented to protrude in a laterally inward direction of an automobile body and joined together. The roof flanges 14, 15, a lateral peripheral portion of the transparent roof panel 4, and the shade support member 6, are disposed within a given positioning zone where they overlap each other in top plan view. The opposite lateral peripheral portion of the transparent roof panel 4 is fixed onto an upper surface of the roof flange 14 of the rail outer panel 7, and the shade support member 6 is fixed to a wall of the rail inner panel 8 at a position outward of the automobile body relative to the roof flange 14 of the rail outer panel 7.
摘要:
In an automatic analyzer for performing qualitative and quantitative analyses of living samples, such as blood and urine, a capability of recognizing the analyzer state, e.g., the state under run of analysis or the stopped state, from a distance is provided without increasing the cost. To realize that capability, the screen saver function of a display is modified to have the function of recognizing the analyzer state and reflecting the recognized analyzer state on a design of a screen image displayed with the screen saver function.

An automatic moving object tracking device and a method thereof are capable of tracking a moving object through a signal process of an input image signal of each frame. The moving object tracking device converts a pre-processed input image signal into a binary disturbance image signal, and calculates a motion value of each pixel through an initial tracking window. After locating the tracking window at the pixel where the motion value is a maximum value, a size of the tracking window is adjusted so that the tracking window can include the moving object therein. Next, based on acquired information about the moving object and the tracking window and previously acquired information about previously frames, a pixel in a following frame is estimated to be a next location of the moving object. The tracking window is positioned at the estimated pixel. If the tracking result is satisfied, the tracking of the moving object continues.
摘要:
The distribution and size distribution of polishing particles contained in a slurry to be supplied to a polishing unit are measured by a measuring machine. Polishing speed with respect to a wafer is controlled to be constant by controlling a physical quantity such as the rotation speed of a polishing surface plate, the rotation speed of a polishing head or the pressurizing force of the polishing head based on the measurement result.
