Abstract: An electroplating apparatus applies an electroplated coating to a female thread formed on a pipe end portion of a steel pipe. The apparatus includes an inner seal member, a capsule, a discharge outlet, an opening, a cylindrical insoluble anode, a plating solution supply tube, and a plurality of nozzles. The seal member divides the interior of the steel pipe at a location longitudinally inward of a region on which the female thread is formed. The capsule is attached to the pipe end portion. The outlet is designed to discharge a plating solution inside the capsule therefrom. The opening facilitates discharge of the solution inside the capsule. The anode is disposed in the inside of the pipe end portion. The supply tube projects from an end of the anode. The nozzles eject a plating solution between the outer surface of the anode and the inner surface of the pipe end portion.

The method for producing the molded product includes: mixing a block copolymer having a hydrophilic segment with the functional material; mixing the block copolymer, which has been mixed with the functional material, with a thermoplastic resin; and molding the thermoplastic resin in which the functional material and the block copolymer are mixed.

Abstract: A threaded joint for pipes comprises a pin and a box, each having a threaded and unthreaded portion metal contact surface. The unthreaded metal contact portion includes a sealing surface and a shoulder surface, the shoulder surface of the pin located on the pin end surface. A non-contacting region where the pin and the box do not contact each other exists between the sealing surfaces and the shoulder surfaces of the pin and the box. One or more grooves is formed in at least one of the pin and the box shoulder surfaces and extending to the non-contacting region and to the interior of the joint. At least one of the contact surfaces has a solid lubricating coating exhibiting plastic or viscoplastic rheological behavior. A total volume V (mm3) of the grooves and coating weight W (g) of the solid lubricating coating satisfy the equation V/W?24 (mm3/g).

Abstract: By a QTL analysis and so forth using 4-HPPD inhibitor-susceptible rice and 4-HPPD inhibitor-resistant rice, a hypothetical gene (HIS1 gene) of an iron/ascorbate-dependent oxidoreductase gene located on a short arm of chromosome 2 of rice has been identified as a 4-HPPD inhibitor-resistance gene. Further, it has also been revealed that a homologous gene (HSL1 gene) of the HIS1 gene is located on chromosome 6 of rice. Furthermore, it has been found out that utilizations of these genes make it possible to efficiently produce a plant having increased resistance or susceptibility to a 4-HPPD inhibitor and to efficiently determine whether a plant has resistance or susceptibility to a 4-HPPD inhibitor.

Abstract: A method for modifying a surface of a polymer such as a thermoplastic resin is provided, in which a supercritical fluid, especially carbon dioxide in a supercritical state is used as a solvent, and the polymer surface is further converted to have highly advanced function or high performance in a short period of time. In the method for modifying the polymer surface of the present invention, a solute is previously applied to the polymer surface. Accordingly, the solute can be permeated into the surface of the polymer swelled by the contact of the supercritical fluid. When this method is used, it is possible to permeate the solute into the polymer at a high concentration in a short period of time.

Abstract: A multilayer film is placed on a subatrate. The multilayer film includes an antiferromagnetic layer, a pinned magnetic layer, a non-magnetic material layer, and a free magnetic layer. The multilayer film has recessed sections arranged in both side regions thereof, the recessed sections being formed by partly removing the multilayer film in a vacuum. The bottoms of the recessed sections are located between the upper face and lower face of the antiferromagnetic layer. Amorphous barrier layers with a thickness of ? are placed on the bottoms of the recessed sections, the amorphous barrier layers being formed in the same vacuum as that for forming the recessed sections sequentially to the step of forming the recessed sections.

Abstract: A fixed magnetic layer contains a first magnetic layer formed on a non-magnetic metal layer. The non-magnetic metal layer is composed of an X—Mn alloy (where X is selected from Pt, Pd, Ir, Rh, Ru, Os, Ni, and Fe). While atoms forming the first magnetic layer and atoms forming the non-magnetic metal layer are being aligned with each other, strains are generated in the individual crystal structures. By generating the strain in the crystal structure of the first magnetic layer, the magnetostriction constant ? is increased. As a result, a magnetic sensor having a large magnetoelastic effect can be provided.

Abstract: First electrode layers are formed on second antiferromagnetic layers, and in a step separate from the above, second electrode layers are formed above internal end surfaces of the second antiferromagnetic layers and the first electrode layers and parts of the upper surface of the multilayer film with an additional film provided therebetween. Since the first and the second electrode layers are formed separately, it is not necessary to perform mask alignment twice, and hence an overlap structure can be precisely formed in which the thickness of the second electrode layer at the left side is equivalent to that at the right side.
