  • Publication number: 20110288325
    Abstract: Disclosed is a silica-supported catalyst having excellent wear resistance, by which an object product can be obtained with excellent yield. Specifically disclosed is a method for producing a silica-supported catalyst which contains Mo, V, Nb and component X (that is Sb and/or Te), and is used in a vapor-phase catalytic oxidation reaction or vapor-phase catalytic ammoxidation reaction of propane. The method for producing a silica-supported catalyst comprises: (I) a step wherein Mo, V, Nb, component X, a silica sol and water are mixed, thereby preparing a starting material blended solution; (II) a step wherein the starting material blended solution is dried, thereby obtaining a dried powder; and (III) a step wherein the dried powder is tired, thereby obtaining a silica-supported catalyst. In the method for producing a silica-supported catalyst, the silica sol contains 10-270 ppm by weight of nitrate ions relative to SiO2.

  • Publication number: 20100116777
    Abstract: A technical problem is to fully make up for a restricted upper limit to the preform body wall thickness. An object is to provide a bottle which is narrow-mouthed and yet has a substantially expanded body. The molding process comprises steps of: (1) injection molding a preform in the shape of a test tube taller than the bottle wherein the preform has a cylindrical mouth opening portion disposed in an upper part of the preform, and wherein the mouth opening portion of the preform serves also as a mouth opening portion of the bottle product; (2) thermally shrinking the preform from an initial height so that portions other than the mouth opening portion of the preform would have a height that is smaller than that of the bottle; and (3) setting this thermally shrunk preform in a blow mold and biaxially drawing and blow molding the preform into the bottle.

  • Patent number: 7171504
    Abstract: A transmission unit that improves communication quality by making effective use of a line to a blocked port in compliance with a spanning tree protocol. Bridges have bridge ports and communicate at the layer 2 level. Physical ports are used for sending and receiving frames via lines. A bridge port state monitoring section monitors the state of ports. A port correspondence table managing section stores and manages a port correspondence table including the state of the bridge ports and the correspondence between the bridge ports and the physical ports in the unit and the correspondence between bridge ports and physical ports in an opposite unit. A switching section switches bridge ports and physical ports on the basis of the port correspondence table so that a line disconnected logically can be used for providing other communication services. A port state management control section sends and receives port state information.

  • Publication number: 20050275721
    Abstract: A monitor camera photographs a whole monitor area for capturing the photographed whole monitor area as high definition image data higher in resolution than a display screen. A new object detection/extraction unit detects a new object in the monitor area based on the high definition image data captured by the monitor camera, extracts partial image data of an area, which contains the new object, from the high definition image data, and obtains location information on the partial image data in relation to the high definition image data. A whole-monitor-area image data down-sampling unit down-samples the high definition image data to produce standard definition image data corresponding to the resolution of the display screen. An image enlargement unit enlarges the standard definition image data based on entered enlargement instruction information.

  • Patent number: 6928613
    Abstract: A storyboard of video clips is divided into zones, or segments. The user selects a zone, and the invention presents a list of effects that are applicable to the selected zone. The user can select among the presented effects in order to apply the effect to the selected zone. Effects that are inapplicable to the selected zone are hidden from view and not displayed. Thus, the overall number of effects that are presented at any given time is reduced, and the process of selecting an appropriate effect is simplified and made easier for novice users.

  • Patent number: 5977985
    Abstract: An improved object-based image processing system and method which minimizes and improves predictability and control over regeneration and recalculation time when the user makes changes to operations. Image clips containing bitmaps of object results are stored to minimize repeated application of operations. Partial updates for modified operations are facilitated so that unnecessary regeneration of the entire region of operation is avoided. Greater user control is achieved by permitting the user to designate a temporary background image.
