The disclosure describes a method for separating a ruthenium complex, which comprises removing an objective hydrogenation reaction product from a hydrogenation reaction solution of an organic carbonyl compound in the presence of a ruthenium complex having a tertiary organic phosphorus compound as ligand to obtain a catalyst solution, contacting said catalyst solution with a polar solvent, and carrying out a phase-separation into a liquid phase substantially composed of the polar solvent and an another liquid phase substantially containing the ruthenium complex.

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.

Radial seal type threaded joints for steel pipes have still room for improvement in ensuring sealability in terms of the rigidity of the pin nose. Specifically, 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; and the cross-sectional area of the pin at a seal point that is a portion on the outer circumferential surface of the nose of the pin, the portion first coming into contact with the sealing surface of the box when threaded-joined, is 35% or more of the cross-sectional area of an original pipe portion corresponding to an unprocessed portion.

Disclosed is a process for preparing a pyrrolidone derivative, which comprises allowing at least one of &ggr;-butyrolactone, 4-hydroxybutyric acid, and a low-molecular polymer of 4-hydroxybutyric acid to react with an alkylamine, wherein (i) the content of a primary amine in said alkylamine is 85% by weight or lower, and (ii) the molar ratio of the total amount of the charged primary and secondary amines to the total amount of the charged &ggr;-butyrolactone, 4-hydroxybutyric acid, and low-molecular 4-hydroxybutyric acid polymers satisfies formula: 1.0≦(A1+A2/2.5)/(B1+B2+B3) wherein A1, A2, B1, B2, and B3 represent the molar amounts of a primary amine, a secondary amine, &ggr;-butyrolactone, 4-hydroxybutyric acid, and low-molecular 4-hydroxybutyric acid polymers, respectively.
摘要:
Over an active region with two bent portions on a semiconductor substrate, first and second word lines extend to cross these bent portions and to be vertically spaced apart from each other. Around at the center of the active region, a capacitor for storing data thereon and a capacitor contact are formed. A first bit line contact, which is connected to the active region, is formed on the opposite side to the capacitor contact across the first word line over the active region. A second bit line contact, which is also connected to the active region, is formed on the opposite side to the capacitor contact across the second word line over the active region. These first and second bit line contacts are provided substantially symmetrically about the center of the memory cell. In a pair of memory cells adjacent to each other along bit lines, one vertical end of the active region in one of the memory cells is continuous with an associated vertical end of the active region in the other memory cell. And each of the first and second bit line contacts is shared between an adjacent pair of memory cells.

A fluid displacement apparatus is disclosed. The fluid displacement apparatus includes a housing, a fixed fluid displacement member and an orbiting fluid displacement member having an end plate from which an orbiting wall extends. The orbiting member interfits with the fixed member to make a plurality of line contacts to define at least one sealed-off fluid pocket. A drive shaft is rotatably supported by the housing, and has a drive pin which is radially offset from the axis of the drive shaft. The end plate of orbiting piston member has a boss, and bushing is rotatably supported within the boss. The bushing has an eccentric hole disposed eccentrically with respect to the center of the bushing, and the drive pin is inserted in the eccentric hole. A restriction device restricts the swing angle of the bushing and is coupled between the drive shaft and the bushing. The restriction device includes a spring to push the orbiting fluid displacement member in the direction to reduce the orbital radius of the orbiting member. The line contacts between fixed member and orbiting member are thereby separated until the orbiting member reaches a predetermined desired rotational frequency. The compressor thus starts up in an unloaded condition.
