  • Publication number: 20060138338
    Abstract: Embodiments include determining whether defects exist in an extreme ultraviolet (EUV) light mask blank. Incident EUV light scattered or diffused by abnormalities in the layers of the mask blank may be measured, normalized, and compared to threshold values to determine if and where a defect exists. Normalizing may be performed by dividing a light intensity value for a pixel by the average of light intensity values for one or more rings of surrounding pixels. A defect may be determined by considering whether the normalized intensity value for a pixel is greater than a pixel threshold to identify the pixel is a candidate for a location with a defect; and by determining whether the sum of normalized light intensity values for a block of pixels including the pixel satisfies a pixel block threshold to determine whether the block scatters or diffuses a critical amount of light to identify a defect.

  • Patent number: 6999094
    Abstract: Smooth, stable and high quality game image is provided by accurately pre-reading background data required for image processing each time. The game device therefore reads background data required for a game that displays a condition of a moving vehicle within a virtual three-dimensional space together with a background in the main memory from a CD-ROM (recording medium) prior to image processing. This device comprises a pre-reading unit for pre-reading background data from a recording medium when reading a start line (reference line) set at a distant position in a specified distance away from the limit line of the visual field direction of display is crossing a new area. A recording medium is a medium that records background data by dividing it into a plurality of areas in advance, and the pre-reading unit comprises a unit for judging on which of the areas the reference line is crossing, and a reading unit for reading in memory the background data of the area judged as being crossed with the reference line.

  • Publication number: 20050153149
    Abstract: This invention relates to aliphatic polyesters having a controlled thermal decomposition, hydrolizability, and biodegradability, in which OH terminals and COOH terminals are decreased through a ring-opening polymerization of a lactone and lactide by a mono alcohol or a metal alkoxide, or by decreasing both terminals through combining polymer terminals with diisocyanate. From a composition containing the polyesters, this invention provides a controlled release composition for agriculture.

  • Publication number: 20040068059
    Abstract: A high molecular weight aliphatic polyester copolymer, a high molecular weight aliphatic polyester copolymer containing polylactic acid; process for industrially producing these copolymers; composition of these copolymers; and various uses thereof. These copolymers have practical properties which make the copolymers moldable. They are free from the problem of plasticizer bleeding and can be degraded by microorganisms present in soils or water. They give moldings, such as sheets and films, which combine a sufficient strength with tear resistance. When the copolymers are ones having a branched structure, they give a molding having excellent mechanical properties. The moldings obtained from compositions containing either of these copolymers are excellent in elongation and biodegradability and have a satisfactory balanc therebetween. In particular, blending with one or more other biodegradable resins gives a molding having better moldability.

  • Patent number: 6698732
    Abstract: A double orifice type liquid-in vibration isolating device including a partition portion fitted between a vibration isolating substrate combined through a body fitting and a first diaphragm made up of a partition main member forming a first orifice, a partition plate member forming a second sub-liquid chamber and a second orifice, and a partition support plate forming the first orifice. An inlet/outlet on the main liquid chamber side of both orifices is common to both orifices. The first orifice is diverged from a part of the second orifice having a liquid passing resistance smaller than that of the first orifice to provide two orifices compactly. Any variation or change of the property can easily be coped with by circumferential position adjustment of the component members of the partition portion.
