Provided is a threaded joint for steel pipes having high sealability even under a bending load. In the threaded joint, when a pin 3 and a box 1 are threadedly connected with each other, the outer peripheral face of a nose 8 of the pin and the inner peripheral face of a nose of the box are in metal-to-metal contact with each other at a contact portion and the contact portion serves as a seal portion 20. A threaded portion, at which the externally threaded portion 7 and the internally threaded portion 5 are threadedly connected with each other, has a negative load flank angle α, shoulder portions 12 and 14 have a negative torque shoulder angle β, and the ratio L/d0 of a length L of the nose and a pipe outside diameter d0 is equal to or higher than 0.08.

Provided is a threaded joint for a pipe in which scalability, compression resistance, and galling resistance are enhanced. Specifically, a pin nose outer peripheral surface forms an outward convex curve in an axial cross-sectional view; the convex curve is such that a composite R curve, in which a plurality of outward convex arcs having different radiuses of curvature are connected in sequence to a generating line of a cylindrical portion next to a male member, is curved such that the radiuses of curvature increase with distance from the male member and tangents on connection points of the arcs are aligned with those of corresponding arcs connected thereto; and the inner peripheral surface of a box component facing the pin nose is a tapered surface that interferes with the pin nose outer peripheral surface when connected to a pin component.

A semiconductor integrated circuit is disclosed which includes a clock synchronous memory, an internal clock generating circuit, a clock selecting circuit, a data output converting circuit, and a data output selecting circuit. The clock synchronous memory is disposed to receive a control signal, an address signal, and a data input and provide an internal data output. The internal clock generating circuit is disposed to generate an internal clock signal having a frequency higher than that of an external clock signal. The clock selecting circuit is disposed to select between the external clock signal and the internal clock signal and send the selected clock signal to the clock synchronous memory. The data output converting circuit is disposed to convert the internal data output into an external data output in synchronization with a clock signal having a frequency lower than that of the internal clock signal. The data output selecting circuit is disposed to select between the internal data output and the external data output and provide the selected data output.
摘要:
A threaded joint for steel pipes that includes a pin and a box. The pin has an externally threaded portion, a nose, and a shoulder portion. The box has an internally threaded portion, a sealing surface, and a shoulder portion. The outer circumferential surface of the nose of the pin has an outward convex curved shape, and the sealing surface of the box has a tapered shape. Additionally, the cross-sectional area of the pin at a seal point is 35% or more of the cross-sectional area of an original pipe portion corresponding to an unprocessed portion of the pin, the seal point being a portion on the pin that first comes into contact with the sealing surface of the box when the pin and the box are joined.
