摘要： This invention relates to a threaded joint for steel pipes which comprises a pin and a box each having a contact surface including a threaded portion and an unthreaded metal contact portion and which guarantees galling resistance and gas tightness in a stable manner without application of a compound grease. A solid lubricating coating comprising a lubricating powder (e.g., molybdenum disulfide) and an organic or inorganic binder is formed on the contact surface of at least one of the pin and the box. The proportion of area of a cross section along the thickness of the solid lubricating coating which is occupied by secondary particles of the lubricating powder having an equivalent circular diameter of 15-60 &mgr;m is from 5-90%. Alternatively, the solid lubricating coating comprises, in addition to the lubricating powder, a fibrous filler (e.g., inorganic whiskers) in such an amount that the mass ratio of the fibrous filler to the binder is 0.01-0.5. As a result, galling resistance is improved, particularly at high temperatures.

摘要： In a threaded joint for steel pipes comprising a pin and a box capable of mating with each other, the pin having an externally threaded portion and an unthreaded metal contact portion as a mating surface, and the box having an internally threaded portion and an unthreaded metal contact portion as a mating surface, the mating surface of at least one of the pin and the box is coated with a lower porous zinc or zinc alloy layer by blast plating and with an upper coating which is either a solid lubricating coating (comprising a lubricating powder in an organic or in organic binder) or a liquid, heavy metal powder-free coating (e.g., a liquid coating based on a highly basic organic acid metal salt such as a highly basic metal sulfonate). The threaded joint exhibits improved galling resistance, rust-preventing properties, and gas tightness even after exposure to a high temperature and makes it possible to perform repeated fastening (make-up) and loosening (break-out) in a high-temperature oil well without application of a compound grease containing a heavy metal powder.

摘要： A signal pickup cartridge is mounted in a signal pickup device having pivot bearings and an actuator driven by the pivot bearings in response to a control signal. The pickup cartridge comprising a cantilever provided at a distal free end thereof with a reproducing stylus for tracing along a track which is formed on a rotary recording medium lying in a horizontal plane and has an information signal recorded therealong and thereby reproducing the information signal. The cantilever is supported at a proximal base end thereof by the pivot bearings in a swingable manner and, moreover, in a manner making possible displacement thereof in the longitudinal direction thereof. The pickup cartridge further comprises pressure contact mechanism for holding the cantilever when the pickup cartridge is in the state thereof prior to the mounting thereof in the signal pickup device and for causing the proximal base end of the cantilever to be pressed into contact with the pivot bearing when the pickup cartridge is in the mounted state in the pickup device, and elastic members capable of absorbing vibration provided at one part of the pressure contact mechanism and holding the cantilever at a part thereof near the proximal base end.
