摘要： In a target for cathode discharging arc ion plating containing Al and Cr as an essential ingredient according to the invention, the thickness of the Al and Cr compound layer formed between Cr particles and Al contained in a target is 30 μm or less. Alternatively, the total for the peak intensities of Al—Cr compound observed between diffraction angles between 10 to 80° by X-ray diffractiometry according to θ=2θ method is 10% or less relative to the total for the peak intensities of Al, Cr and the Al—Cr compound. Further, the relative density of the target is 92% or more. The target is capable of forming hard films of high quality while preventing not uniform movement of arc spots and suppressing formation of macro particles.

摘要： In a gear spindle, outer cylinder gear sections (11) are each integrally formed on an inner peripheral surface of a spindle outer cylinder and inner cylinder gear sections (14) are each integrally formed on an outer peripheral surface of a spindle inner cylinder (13). An oil seal (27) that seals in the lubricating oil (20) for each of the aforementioned gear sections includes, a seal body (29) having a channel-shaped cross section and interposed in the peripheral gap between the inner peripheral surface of the spindle outer cylinder and the outer peripheral surface of the spindle inner cylinder (13), and a seal mounting member (30) that includes a band, a spring, or the like that tightens and fixes the seal body to the outer peripheral surface of the spindle inner cylinder (13) to allow expansion of the seal body in the axial direction in the aforementioned peripheral gap.

摘要： A press-forming mold has a protective film for preventing seizing during press-forming formed on at least a forming surface that comes into contact with a formed body. The protective film is formed by PVD. An arbitrary selection section extracted from the surface of the protective film is divided into a plurality of individual sections; and, when the gradient of the surface at the nth division point is represented by (dZn/dXn), taking N to represent the number of divisions, the root-mean-square RΔq calculated by the following numerical expression is no greater than 0.032. R ⁢ ⁢ Δ ⁢ ⁢ q = 1 N ⁢ ∑ n = 1 N ⁢ ⁢ ( d ⁢ ⁢ Z n d ⁢ ⁢ X n ) 2 It is thereby possible to improve the seizing resistance of a press-forming mold having a protective film formed by PVD.

摘要： A method for quenching a steel pipe by water cooling from an outer surface thereof, where pipe end portions are not subjected to water cooling, and at least part of a main body other than the pipe end portions is subjected to water cooling. A region(s) that is not subjected to direct water cooling over an entire circumference thereof can be along an axial direction at least in part of the main body other than the pipe end portions. The start and stop of water cooling can be intermittent at least in part of the quenching. During the water cooling of the pipe outer surface, an intensified water cooling can be performed in a temperature range in which the pipe outer surface temperature is higher than Ms point. Thereafter, the cooling can be switched to moderate cooling so that the outer surface is cooled down to Ms point or lower.

摘要： In a transparent electroconductive film including a transparent substrate and a transparent electroconductive oxide layer disposed on the transparent substrate, when the transparent electroconductive oxide layer is composed of zinc oxide, the surface resistivity of the transparent electroconductive oxide layer increases with time and thus it has been difficult to obtain a transparent electroconductive film stable against an environmental variation. Consequently, hard carbon films are provided on the surfaces of a transparent electroconductive oxide layer including at least one layer and containing zinc oxide as a main component in “the order of transparent substrate-hard carbon film-transparent electroconductive oxide layer-hard carbon film” or “the order of hard carbon film-transparent substrate-transparent electroconductive oxide layer-hard carbon film”. Alternatively, an organosilicon compound covering layer is provided on a surface of the transparent electroconductive oxide layer. Thereby, the water contact angle can be 75 degrees or more, and an increase in the resistivity of the transparent electroconductive oxide layer can be suppressed.
