  • Publication number: 20100227444
    Abstract: A mask having mask patterns for the transfer of a desired circuit pattern, a method for manufacturing the mask, and a semiconductor device manufacturing method using the mask, are provided. There are extracted two rectangular aperture patterns which are adjacent each other in an obliquely disposed state with respect to an X axis in an XY plane. The thus-extracted two rectangular aperture patterns are rotated at a certain angle so that a pattern edge corresponding to one side of one of the rectangular aperture patterns and a pattern edge corresponding to one side of the other rectangular aperture pattern are opposed in parallel to each other. The two rectangular aperture patterns thus rotated at a certain angle are then subjected to optical proximity effect correction to form two corrected rectangular aperture patterns.

  • Publication number: 20100149136
    Abstract: In a display device, when a first image is an absolute white image, a direction in which a luminance is maximum is regarded as a main viewing direction for the first image. A luminance Ld in the main viewing direction for the first image in cases where the first image is an absolute black image and other image is an absolute white image, and a luminance Lb in the main viewing direction for the first image in cases where the first image and the other image are absolute black images satisfy a relationship represented by Formula (1): (Ld?Lb)/Lb?2.5??(1). This makes it possible to realize a display device, which is capable of displaying different images to a plurality of different viewpoints and has an improved function of separating the images in the different display directions.

  • Publication number: 20090303157
    Abstract: A display device (1a) of the present invention includes a displaying section (10), an image generating section (2) for generating an image signal, and a parallax barrier aperture array (17), distinction means (3) for judging whether cross talk of an image of another-pixels reaches a level at which the cross talk is perceived by a viewer of an image of self-pixels, and adjustment means (4) for adjusting the pixel signals of the another-pixels so as to eliminate the cross talk, in a case that the distinction means (3) judges the cross talk of the image of the another-pixels reaches to the perceivable level. This provides a display device and a vehicle equipped therewith, both of which display, on a single display screen, different images in a plurality of display directions and thus are capable of providing excellent display environments wherein the viewer of an image displayed in one display direction does not perceive cross talk of an image displayed in another direction.

  • Publication number: 20090225002
    Abstract: A multiplex image display device prevents onscreen input buttons from appearing at the same positions. A “command area” refers to an area of the display screen where the user can enter a command for manipulating one of images being simultaneously displayed on the single display section for individual viewing from different directions. In the multiplex image display device, the positioning control section controls the positioning of the command areas so that a command area for one of the images being simultaneously displayed on the display section is displayed at a different (i.e., non-overlapping) position on the display section from a command area for another one of such images.

  • Patent number: 7570058
    Abstract: A system and method for the monitoring and treating of a coolant in a cooling system of an MRI system includes a deionization kit connectable to the cooling system of the MRI system. The deionization kit receives coolant from the cooling system to deionize the coolant and forms a closed-loop system with the cooling system when connected thereto. The deionization kit thus allows for unimpeded circulation of the coolant through the deionization kit and the cooling system. Accordingly, the MRI system may remain in operation and be used to perform MR image acquisitions of an object while the deionization kit is connected to the cooling system.
