  • Patent number: 7816582
    Abstract: It is intended to provide a gene encoding a protein having an activity of improving a tolerance to an environmental stress such as salt, moisture, or heat stress, in particular, a tolerance to water stress; a protein having an activity of improving a tolerance to an environmental stress; a transgenic plant having an enhanced tolerance to an environmental stress, and so on. A halophyte Salicornia europaea, which has a strong activity of improving a tolerance to water stress and can grow even in a dry area with much salt accumulation, was used to search genes participating in the salt tolerance of Salicornia europaea by a functional screening method using an Escherichia coli gene expression system, with the aim of isolating genes (cDNAs) participating in the salt-tolerance mechanism of Salicornia europaea.

  • Publication number: 20060288438
    Abstract: The invention provides novel, carrot-derived MITE-like elements (transposable elements). It further provides transcriptional activation elements comprising at least one transposable element, in particular one of the above MITE-like elements. Specifically, it provides transcriptional activation elements having a DNA comprising the nucleotide sequence shown under SEQ ID NO:1 or a functional equivalent thereto and/or a DNA comprising the nucleotide sequence shown under SEQ ID NO:2 or a functional equivalent thereto. The transcriptional activation elements of the invention can increase or activate the reduced expression of a foreign gene introduced by the transgenic technology. Therefore, the transcriptional activation elements contribute to stable expression of a foreign gene introduced in a plant genome and are useful in stably producing genetically modified plants.

  • Publication number: 20060110087
    Abstract: Both end portions in an axial direction of a hub 8b are supported by a supporting portion of a working apparatus rotatably centering on a center axis of the hub 8b and in a state of restraining a displacement thereof in a radial direction. Further, before removing the hub 8b from the supporting portion from the state, an outer side face 28 of an attaching flange 13 and a first inner ring track 14 are worked to predetermined shapes. Thereby, judder in braking is prevented from being brought about by promoting a perpendicularity of the outer side face 28 of the attaching flange 13 provided to the hub 8b relative to a rotational center of the hub 8b and restraining a deflection of a rotor coupled to fix to the outer side face 28.

  • Patent number: 5916380
    Abstract: An Fe--Ni alloy for use as a part 10 of an electron-gun 4 is press-blanked by a punch to form minute apertures 10a, 10b, 10c for passing an electron beam 3. The burrs 10 formed around the minute apertures 10a, 10b, 10c are detrimental to such part 4. The Fe--Ni alloy according to the present invention essentially consists of from 30 to 55 wt % of Ni, not more than 0.5 wt % of Si, not more than 1.5 wt % of Mn, and the balance being Fe and unavoidable impurities. The alloy includes from 10 to 1,000 of A type or B type non-metallic inclusions of 10 .mu.m or more in length per 1 mm.sup.2 of longitudinal cross section, and from 100 to 50,000 of C type non-metallic inclusions having a diameter of 5 .mu.m or less.

  • Patent number: 5849420
    Abstract: A punched part consists of an Fe--Cr--Ni alloy essentially consisting of from 15 to 20% of Cr, from 9 to 15% of Ni, from 0.001 to 0.0050% of S, the balance being Fe and unavoidable impurities. The burrs formed during punching are suppressed due to addition of S to the Fe--Cr--Ni alloy.

  • Patent number: 5645654
    Abstract: A nonmagnetic stainless steel for high burring has the absolute value of the plane anisotropy .DELTA.r of the Lankford value r of 0.12 or under, the .DELTA.r being .DELTA.r=(r.sub.0 +r.sub.90 -2r.sub.45)/2 wherein r.sub.0. r.sub.45, and r.sub.90 are the r-values at angles of 0.degree., 45.degree., and 90.degree., respectively, to the direction of rolling to which the steel is subjected. The nonmagnetic stainless steel is useful for electron tube parts, especially for the electrodes of electron guns for color picture tubes and is made by the steps of adjusting the grain size of a nonmagnetic stainless steel before final rolling to the range from 4.0 to 7.0 in the austenite grain size conforming to JIS G0551, finishing the work to a desired thickness by final cold rolling to a cold reduction of 20 to 50%, and finally annealing the same to an austenite grain size according to JIS G0551 ranging from 7.0 to 12.0.
