    摘要: A threaded joint for steel pipes comprises a pin (1) and a box (2) each having a threaded portion (3a or 3b) and an unthreaded metal-to-metal contact portion (4a or 4b) as contact surfaces which contact each other when the joint is fastened. The contact surfaces (3a and 4a and/or 3b and 4b) of at least one of the pin (1) and the box (2) are coated with a lower layer of a solid lubricating coating containing a solid lubricating powder (e.g., molybdenum disulfide, tungsten disulfide, or graphite) and a binder (e.g., an epoxy or other organic resin) and an upper layer of a solid corrosion protective coating formed by an organic resin which does not contain solid particles.

    摘要: To provide a display panel having such a structure that a color filter is unlikely to suffer a damage due to a heat treatment in a reducing atmosphere in the fabrication process for display device. A display panel (anode panel AP) comprises a fluorescent region formed on a substrate, and an electrode (anode electrode) formed on the fluorescent region, wherein electrons emitted from an electron source penetrate the electrode and collide with the fluorescent region to allow the fluorescent region to emit light to obtain a desired image, wherein a color filter and a color filter protective film are formed in this order from the side of the substrate between the substrate and the fluorescent region.

    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.
