  • Publication number: 20090131271
    Abstract: In a method for delivering a nucleic acid of the invention, a nucleic acid is introduced into a cell by pressing the nucleic acid supported on a surface of a solid substrate against the cell. According to the method, the nucleic acid can be delivered into the cell simply at a low cost without placing a heavy burden on the cell at a high nucleic acid delivery efficiency. By allowing the surface of the solid substrate to support the nucleic acid in the form of a complex with a polyamine or a cationic lipid and pressing it against the cell, the introduction efficiency into the cell can be further improved. In the invention, by using a nucleic acid useful for gene therapy as the nucleic acid, a high-efficiency device for gene therapy can be obtained.

  • Publication number: 20080231981
    Abstract: A partial curved on-vehicle rear view mirror, wherein a center main portion (1) is formed in a flat surface, but an outer portion (2) is formed in a gentle convex surface toward the outside, a lower portion (4) is also formed in a gentle convex surface toward the lower side, and an inner portion (3) is also formed in a convex surface toward the inside so that the view of the mirror can be safely and efficiently increased in each direction. Since the center main portion (1) is formed in the flat surface, the safety of the operations of automobiles, motorcycles, and so on can be sufficiently increased by sufficiently expanding the rear view to the sides and also expanding the view in the lower side while sufficiently securing visual stability.

  • Patent number: 6729252
    Abstract: A thread winder unit, which is capable of winding thread of spools set on spool bars, is removably attached to a machine body. The sewing machine includes a feed motor for feeding the thread during sewing, an upper thread state detecting sensor disposed between the feed motor and the thread winder unit for detecting tensed thread, and a CPU for controlling thread winding operations based on a signal from the upper thread state detecting sensor. The sewing machine intermittently drives the feed motor in a reverse direction to that in the sewing to feed the thread toward the thread winder unit, every time the upper thread state detecting sensor detects the tensed thread, and the thread winder unit winds the fed thread around the spool. The CPU, recognizing the thread wound by a given amount, stops winding.
