A feed yarn package conveyor system which is capable of automatically conveying feed yarn package to a doubler. It comprises a discharge conveyor and a feed conveyor along the front and rear sides of a machine base; conveyors arranged in two rows on the right and left sides of each spindle, divided to the front and rear; a series of conveyors ranging from the discharge conveyor to the feed conveyor being declined towards the front of the machine base, with the front conveyor on the side of each spindle being set in a take-up position, such that the conveyors will be declined towards a center when feed yarn packages have been received thereat.
摘要:
In a suspension system of a vehicle which the damping force characteristic is changed into three or more characteristics, the damping force characteristic is changed step by step when the damping force characteristic selected by a given control rule is different from the damping force characteristic at that moment in several steps. Also, the running state is detected by detecting means and the damping force characteristic to be selected is limited to two or so from three or more characteristics according to the vehicle running state. The damping force characteristic is changed only within the above selected damping force characteristics based on a given control rule. Through the above, noise and oscillation caused by large changes of the damping force characteristic can be lowered.

An apparatus for measuring the density or the like of an object from the level of transmission through the object of gamma rays having different energy levels which are transmitted at the object by a gamma source having a predetermined solid angle of transmission. A collimator collimates gamma transmitted through the object and a scintillator generates light corresponding to the output of the collimator. Plural photomultipliers generate position-dependent electrical signals corresponding to the light generated by an incident gamma ray photon to the scintillator. A calculating circuit generates a density spectrum for the object from the position-dependent electrical signals by integrating the position-dependent electrical signals corresponding to each of the incident gamma ray photons to the scintillator.

A spinning winder in which a spinning frame and an automatic winder are integrally associated. The spinning winder provides carrier routes comprising routes for transporting a spinning bobbin from the spinning frame to the automatic winder and routes for returning an empty bobbin discharged from the automatic winder to the spinning frame and also provides a passage for an operator between the spinning frame and the automatic winder.

A package storage system comprises a package conveyor disposed next to the package conveyor of the associated winder, a package stocker beside the former package conveyor, and a package transferring mechanism which includes a package positioning device for positioning the package at transfer position and a package transferring device for transferring the package to the stocker.
摘要:
A process for purifying gases containing hydrogen sulfide and/or hydrogen cyanide is provided wherein said gases are contacted with an absorbing solution containing naphthols or their salts as a catalyst having a nitroso group at .alpha.-position or .beta.-position and also acidic group(s) and also having a standard redox potential in the range of 0.4 V or higher but lower than 0.7 V to remove hydrogen sulfide and/or hydrogen cyanide by converting the former mainly into thiosulfuric acid and the latter mainly into thiocyanic acid. According to this process, no trouble caused by sulfur deposit as seen in conventional method occurs, and the scale of purification apparatus is made smaller, and also the amount of catalyst required for purification is reduced. Further, by pretreating the absorbing solution, this process becomes more advantageous.
摘要:
A yarn piecing and knotting device for use in a pneumatic spinning machine for spinning slivers directly into a yarn by air jetting nozzles is disclosed. This yarn knotting device comprises means for retaining a spun yarn temporarily during a period ranging from the time of completion of the operation of a yarn knotter for connecting the spun yarn with a yarn taken out of a package to the time of resumption of winding.

Provided is a fluorine- and epoxy group-containing copolymer with excellent workability at room temperature, high water-repellency, and excellent characteristics as a water vapor barrier. Also provided is an efficient method for producing said copolymer. The fluorine and epoxy group-containing copolymer is characterized by containing at least a monomer unit represented by general formula (1): {Therein, R1-R10 each independently represent an alkyl group having 1-3 carbon atoms or a hydrogen atom, R11 is a hydrogen atom, methyl group, or phenyl group, and R5 or R6 can be linked with R7 or R8 to form a ring.} and a monomer unit represented by general formula (2): {Therein, R12 and R13 each independently represent a hydrogen atom or a fluorine atom; R14 represents a hydrogen atom, fluorine atom, methyl group or trifluoromethyl group, and R15 represents a flourine atom or perfluoro group having at most 12 carbon atoms}.
摘要:
The present invention provides a technique capable of manufacturing a resin stamper at a low cost. A method of manufacturing a plate-shaped resin stamper includes: pressing a resin composite base material against a mother stamper having a pattern formed on the surface thereof by compression molding to transfer the pattern of the mother stamper to the composite base material; and punching the composite base material. In the manufacturing method, the resin composite base material includes at least one curing resin. In addition, during the compression molding, a portion of the composite base material is cured by active energy beams or heat, the pattern is transferred to the composite base material, and the composite base material is punched, thereby manufacturing the resin stamper.
