Title: Rice plant peroxidase gene
Inventor: ITO HIROYUKI
IPC: C12N15/53
Filed: 1991-03-14
Abstract: PURPOSE:To obtain the subject gene of rice plant, having a specific base sequence and useful as a marker gene, etc., for rice plant genome analysis by preparing an mRNA from a green leaf of the rice plant, then synthesizing a cDNA and carrying out screening from the resultant cDNA library and providing the base sequence. CONSTITUTION:A rice plant seed is subjected to water absorption overnight and germinated in an experimental greenhouse kept at a constant temperature of 25 deg.C. On the 25th day, green leaf parts are harvested and liquid nitrogen is subsequently added to the green leaves, which are pulverized in a blender. A guanidine thiocyanate solution is then added thereto and the green leaves are completely crushed with a homogenizer. The obtained homogenate is subsequently filtered through a nylon membrane and the filtrate is centrifuged to afford a supernatant, which is then superposed on a CsCl solution in a tube containing the CsCl. solution. The superposed solutions are subsequently ultracentrifuged to separate precipitates. Thereby, the whole RNA is collected to isolate an mRNA therefrom. The resultant mRNA is used as a template to synthesize a cDNA and a cDNA library is prepared by a conventional method and then screened with a probe to select a positive alone. A DNA is then isolated from the positive clone to provide the objective rice plant green leaf peroxidase cDNA IIB gene expressed by the formula.

Title: Article fixture for wall surface
Inventor: INAMI MASAYUKI
IPC: F16B47/00
Filed: 1999-02-12
Abstract: PROBLEM TO BE SOLVED: To fit an article to an unspecified wall surface by peeling the peeling paper of one side of a pressure-sensitive adhesive double-sided coated tape, and peeling the peeling paper of the opposite side thereof after affixing the tape to a wall surface for fixation, and holding a suction cup so that a sucking surface is warped, and pushing the center of the sucking surface to the center of the tape and thereafter affixing the tape, while directing the sucking surface outside. SOLUTION: The end of a pressure-sensitive adhesive double coated tape is cut, and a peeling paper of one surface thereof is provided with a notch. After peeling the peeling paper of a side, which is not provided with a notch, only the peeling paper of a part A is peeled, and a suction cup is pushed to a wall surface for fixation so that the center of the sucking surface and the center of the pressure-sensitive adhesive double coated tape coincide with each other. Finally, both sides of the sucking surface are raised so as to peel the residual peeling paper, and the whole surface is fixed. At this stage, the sucking surface is attached in order from a part near the center toward the outside so that the sucking surface is tightly fitted to the wall surface and that the suction cup is fixed to the wall surface in the condition that the suction cup is expanded.  With this method, since the peripheral surface is not fixed until the last even if the suction cup is pushed against normally, the same effect as with fixation by holding the sucking surface while warping it and fixing the center part prior to a peripheral part can be obtained.
