Abstract: The present invention relates to a plant having an improved sugar content in fruit compared with its wild type plant, which has a mutant cyclin F-box gene comprising a nucleotide mutation that causes a non-conservative amino acid substitution in the cyclin F-box protein. The present invention also relates to a parthenocarpic plant having a mutant cyclin F-box gene comprising a nucleotide mutation that causes a non-conservative amino acid substitution in the cyclin F-box protein.

Abstract: The present invention provides a photosensitive resin composition comprising an unsaturated group-containing resin (D), a (meth)acrylic compound (E) having a specific structure, a silane compound (G) having a substituent selected from the group consisting of an amino group, an amide group, a ureido group, a ketimine group, and an isocyanate group, and a photo-polymerization initiator (F), the unsaturated group-containing resin (D) being obtained by adding an epoxy group-containing unsaturated compound (C) to some acid radicals of a copolymer obtained by copolymerizing a (meth)acrylic ester (A) with an unsaturated group- and acid-containing compound (B).

Abstract: In manufacturing of welding wires, rough surfaces are formed on the product wires to ensure retention of applied lubricants for satisfactory feeding performance. For this purpose, steps of dry hole die drawing with an application of powder lubricants, roller dies drawing, and wet hole die drawing are executed, at least in a part of a sequence of wire drawing processes. As a result of denting of the powder lubricants on the surfaces of the wires during the dry hole die drawing, rough surfaces are formed on the drawn wires.

Abstract: A multi-tier winding coil 1 of a welding wire in a hollow cylindrical configuration having a beginning wire end which is located in the innermost tier and at one of cylinder end faces, a combination of such coil with a shipment packaging box 21, and a combination of the coil 1 and a wire feed adapter 5 which is used to mount the coil on a welding machine are disclosed. The coil 1 includes bundling wires 3a-3d. The beginning wire end of the coil is bent to extend in a radial direction of the coil loop, and is then bent in a direction to extend parallel to the center axis of the coil, thus defining an L-configuration 1sr+1sa. A wire feed adapter 5 includes a barrel 5b formed with notches 5br-5br4 and 5ar-5a4 for receiving beginning ends 1s.

Abstract: A cross roller bearing is disclosed that achieves a long service life by reducing the effects of split surfaces formed in an outer ring in the direction that crosses a V-shaped groove of said outer ring. In addition, a cross roller bearing is disclosed that allows said effects to be reduced at low cost.The above-mentioned advantages are obtained by forming a recess in the outer surface of said outer ring corresponding to said split surfaces to reduce the preliminary pressure applied to rollers at that portion.In addition, the above-mentioned advantages are achieved at low cost by the filling of a filling member and the setting of the angle at which said split surfaces cross said V-shaped groove.

Abstract: A rolling contact type rotary bearing assembly includes a pair of inner and outer rings and a plurality of rolling members interposed therebetween to provide a relative rotation between the inner and outer rings. An insertion hole is provided in at least one of the inner and outer rings such that the plurality of rolling members may be inserted into the annular path defined between the inner and outer rings. A closure member is also provided to close the insertion hole after insertion of the rolling members into the annular path. The closure member is formed with a lubrication hole so that a lubricant may be provided to the annular path to allow a smooth rolling movement of the rolling members. A lubricant supply hole may also be provided in either of the outer and inner rings in communication with the lubrication hole of the closure member so as to allow to supply a lubricant to the annular path from the exterior.

Abstract: A crossed roller bearing assembly includes an outer ring provided with an outer V-shaped guide groove, an inner ring provided with an inner V-shaped guide groove and a plurality of rollers arranged in a guide space defined between the outer and inner V-shaped guide grooves in a rolling contact fashion. An insertion hole is formed in one of the outer and inner rings and the insertion hole preferably has a diameter which is larger than the diameter of the rollers, but smaller than a diagonal length in cross section of the rollers. A plug having a shape which substantially corresponds to the shape of the insertion hole is fitted into the insertion hole after insertion of the rollers. No gap or clearance is defined between the insertion hole and the plug so that the rollers can roll along the guide space smoothly.
