  • Patent number: 7154028
    Abstract: An objective of the present invention is to provide DNAs encoding novel plant proteins having a gibberellin (GA) 2-oxidation activity. Another objective is to modify plant height by utilizing these DNAs for regulating the gibberellin content. PCR was performed using degenerate primers, and novel OsGA2ox2 and OsGA2ox3 genes were obtained. The present inventors discovered that unlike products of other GA2-oxidases such as OsGA2ox1, the product of OsGA2ox3 catalyzes the two-step oxidation of GA20 to GA29 and then of GA29 to GA29-catabolite. In addition, the present inventors also found that the growth of the transgenic rice plants expressing OsGA2ox3 was suppressed as compared to control plants.

  • Patent number: 6872285
    Abstract: This application discloses a system for depositing a magnetic film for a magnetic recording layer or depositing an underlying film prior to depositing a magnetic film as a recording layer. The system comprises; a chamber in which the film is deposited onto a substrate by sputtering, a target that is provided in the chamber and made of material of the film to be deposited, a sputter power source for applying voltage to the target for the sputtering, and a direction control member for controlling sputter-particles released from the target during the sputtering. The direction control member is provided between the substrate and the target. The direction control member provides a passage for the sputter-particles. The direction control member lets the sputter-particles selectively pass through, thereby allowing magnetic anisotropy to the magnetic film. The passage is not close but open in its cross section.

  • Patent number: 6740209
    Abstract: This application discloses a multi-layer film deposition apparatus comprising; plural cathodes comprising targets respectively, a main rotation mechanism for rotating each cathode together, and a substrate holder to hold a substrate onto which a multi-layer film is deposited by sputtering. The targets are arranged at positions where their center axes are on a circumference. The main rotation mechanism rotates the cathodes around the axis in common to the circumference. The substrate is located at a position within an area in view to the direction of the axis. The area is formed of two loci of points on the rotated targets. One of the locus is drawn by the point nearest to the axis, and the other locus is drawn by the point furthest from the axis.

  • Patent number: 6660089
    Abstract: A substrate support mechanism of the present invention, which holds the inner rim of a disc substrate having an opening at its center, comprises: a hollow cylindrical member; a central shaft having a tapered portion disposed in the cylindrical member so as to be axially pushed by a first spring; and a plurality of radially movable members, each of which is pushed inwardly by a second spring and has a click to grip the inner rim; whereby the axial motion of the central shaft is converted by the tapered portion to the radial motion of said radially movable members to grip and release said substrate. A substrate rotation device includes a mechanism for axially moving the cylindrical member; a mechanism for axially moving the central shaft; and a mechanism for rotating the cylindrical member in addition to the substrate support mechanism.
