  • Patent number: 11504674
    Abstract: A polyolefin microporous film having a laminated structure provided with at least one layer A containing a polyolefin and at least one layer B containing a polyolefin. 0 mass % to less than 3 mass % of polypropylene is contained in layer A and 1 mass % to less than 30 mass % of polypropylene is contained in layer B. When the proportion of polypropylene contained in layer A is represented by PPA (mass %) and the proportion of polypropylene contained in layer B is represented by PPB (mass %), PPB>PPA. In the polyolefin microporous film, the heat shrinkage ratio in TD at 120° C. measured upon applying, in MD, a constant load determined on the basis of the relationship: load (gf)=0.01×piercing strength (gf) of polyolefin microporous film×length (mm) in TD of polyolefin microporous film, is 10 to 40% inclusive.

  • Publication number: 20070173466
    Abstract: The present invention relates to methods for treating inflammatory diseases accompanied by bone destruction, comprising the step of administering a viral vector comprising a gene which inhibits signal transduction mediated by fibroblast growth factor-2 (FGF2)-FGF receptor 1-Ras-Raf-MAP kinase to a diseased region. Furthermore, the present invention relates to therapeutic compositions for inflammatory diseases accompanied by bone destruction, which comprise these vectors. By inhibiting FGF2 signal transduction through local administration of viral vectors, both inflammation and bone destruction in inflammatory bone destruction were simultaneously suppressed. The present invention provides disease-specific and effective therapeutic methods, and therapeutic compositions for inflammatory diseases such as osteoarthritis, for which therapy has so far been difficult.

  • Patent number: 7001272
    Abstract: A game system that allows a player to manipulate a real interface device in a real space and have a representation of the real interface device (i.e., a virtual interface device) be displayed in a virtual space is disclosed. The position of the real interface device in the real space is detected by a position detector and converted into spatial coordinates by a three-dimensional input conversion means at predetermined time intervals. When a player moves the real interface device, a virtual interface device is displayed within the virtual space and moves identically with the real interface device. The virtual interface device is determined to have struck an object in the virtual space (e.g., an enemy) when the coordinates of at least a portion of the object in the virtual space are the same as, or within a predetermined range of, the coordinates of the virtual interface device.

  • Patent number: 6786848
    Abstract: An exercise assisting apparatus including a cycling machine, a rotation sensor for detecting pedaling movement of the cycling machine, a pulse sensor for detecting the pulse rate of the user, an exercise monitoring unit for monitoring the pulse rate of the user based on the detection results of the rotation sensor and the pulse sensor and a monitor for displaying a background image and a role-playing character. The apparatus also includes an image processor for causing the role-playing character to make a simulated motion related to the pedaling movement within the background image on the monitor based on the detection result of the rotation sensor, a game executing unit for causing the roll-playing character to jump, and a game evaluating unit for giving a higher evaluation when a landing position after the jump is closer to the position reached when the jump is made at a preset target pulse rate.
