The invention discloses a cold-heading finished silk treatment process. The process comprises the following steps: (1) putting the finished silk into a nodulizing annealing furnace for nodulizing annealing; (2) checking the finished silk subjected to the nodulizing annealing, and performing aging treatment on the qualified finished silk; (3) putting the finished silk subjected to aging treatment into a treatment pool and performing surface treatment: (a) performing three passes of acid washing in an acid washing pool; (b) performing water washing in a water washing pool; (c) performing oxalic acid washing in an oxalic acid pool; (d) phosphorizing in a phosphorizing pool; and (e) saponifying in a saponifying pool; and (4) drying. By adopting the process disclosed by the invention, the treated cold-heading finished silk has the advantages of high nodulizing rate and low decarbonization rate and easiness in lubrication and use; for a cold-heading product which is very difficult to produce and has a complicated structure, the quality of the product is good, the cracking in the product cold-heading process can be prevented, and the service life of a die is remarkably prolonged.

The present invention relates to a compressor in which a rotary member (130) suspended on a stationary member (140) is rotated to compress the refrigerant. The rotary member (130) is suspended on a first portion of the stationary member and rotatably supported on a second portion of the stationary member, which is spaced a distance the first portion of the stationary member to thereby achieve structural stability, improve operational reliability and reduce vibrations. The components can be easily centered and assembled with excellent assembly characteristics. In addition, the mounting structure of an elastically-supported vane (133) is improved to ensure lubrication performance and operational reliability. Moreover, a mounting structure for a vane (234), which incorporates a roller(233), is improved to reduce vibration and prevent refrigerant leakage, which leads to high compression efficiency.

An emergency lubrication device of simplified architecture for a mechanical system. The emergency lubrication device has a tank, trigger means, at least one pipe, and at least one distribution means. The tank contains a lubrication liquid and it is arranged inside the mechanical system and above the pipes and the distribution means. Each distribution means includes at least one constriction means for limiting the flow rate of the lubrication liquid. The lubrication liquid is heated by the mechanical system, and the viscosity of the lubrication liquid decreases so that the flow rate of the lubrication liquid through each distribution means is substantially equal to or greater than a minimum flow rate so long as the tank contains the lubrication liquid.

Provided is a scroll compressor having an improved function of oil circulation and back pressure control. The scroll compressor includes: a housing; a drive part for generating a rotational force; a drive shaft driven by the drive part; and a scroll compression part including a stationary scroll fixed regardless of rotation of the drive shaft and having a scroll wrap for compressing sucked fluid and a discharge port for supplying coolant into a discharge chamber, and an orbiting scroll orbited depending on rotation of the drive shaft and having a scroll wrap, characterized in that the coolant compressed by the scroll compression part is conveyed to the discharge chamber, the coolant of the discharge chamber is separated into oil and gas in an oil separator, the gas being discharged through a discharge hole and the oil being supplied into a back pressure chamber through a return path formed in the stationary scroll, and the oil is returned into a suction chamber through a back pressure adjustment valve.

A connection device (1) for connecting a remaining bar (26) and a movement bar (28) of a transfer bar (1) is configured of a remaining clamp (3) and a movement clamp (4). A male fitting section (K1) and a female fitting section (K2) which fit to each other in the connection direction are provided to the clamps (3, 4) so as to serve as a first connection section (R1). A male engagement section (44) and a female engagement section (33) are contained within the clamps (3, 4) so as to serve as a second connection section (R2). The female engagement section (33) of the second connection section comprises spheres (36) serving as movement members which move in the direction perpendicular to the connection direction. The female engagement section (33) is engaged with and disengaged from the male engagement section (44) by the movement of the spheres (36).

An automatic screw machine (20) has a body (22), and a head (21) that is rotatably mounted on the body and that is adapted to be selectively rotated relative to the body between any of a plurality of index positions. The body and head have closely-spaced and facing bearing surfaces (25, 28 and 26, 29), have spindles (23) journalled on the head for rotation relative thereto, and have a source of pressurized lubricant. The improvement broadly includes: at least one body passageway (32) communicating the source with the body bearing surface, the intersection of each body passageway with the body bearing surface defining a body port (33); a head passageway (36) communicating the head bearing surface with the spindle, the intersection of said head passageway with said head bearing surface defining at least one head port (42); and the body and head passageways being so configured and arranged such that lubricant may flow from the source to the spindle only when the head is in the vicinity of the index position such that the body and head ports overlap one another.
