Abstract: The present invention provides an optical fiber connector cleaner in which the rotation of the cleaning shaft is linked with the feeding of the cleaning tape so that it is possible to wipe the dirt on the end surface of the connector off reliably. A forwarding and reversing mechanism of the optical fiber connector cleaner is formed of a fixing member contacting the second casing so as to be slidable, and a coil spring biasing the second casing forward in the one direction for the fixing member, a rotation mechanism is formed of a first rack gear disposed on the fixing member, a first gear rotatably mounted in the second casing, and a second gear connected to a base end of the shaft 14, the first gear includes first teeth fitted to the first rack gear, and second teeth fitted to the second gear.

Abstract: An optical fiber connector cleaner (1) comprises a housing (10), a winding means (32) and a delivery means (34) for a cleaning tape (T) which are disposed in the housing, a cleaning means (20) having a bar-like cleaning section (21) projecting outwardly of the housing, on the front-end of the cleaning section the cleaning tape delivered from the delivery means being movably mounted under tension in an exposed state, the front-end of the cleaning section being brought into contact with the end surface of an optical fiber connector to thereby clean the end surface, a cleaning section rotating means (23) coaxially connected to the cleaning section in the housing and rotatably supported with respect to the housing; and a transmission means (40) which rotates the winding means and the cleaning section rotating means substantially simultaneously in a predetermined direction through a predetermined angle and then reverses the cleaning section rotating means to its original position.

Abstract: Disclosed is a flaky material formed of an aggregate of fine particles. The aggregate is formed by uniting fine particles to one another. The fine particles are derived from fine particles of an inorganic oxide dispersed in a solvent having an effective (OH?) content of 3×10?5 to 1×10?6 mol/l. The surface of the flaky material has a flatness degree equal to or lower than 0.5 ?m. The flaky material can provide viewers with a high brightness feeling.

Abstract: A connecting end face cleaning tool having superior cleaning properties includes a cleaning fabric. This cleaning tool removes soiling attached to the connecting end face of an optical connecting part when that connecting end face is detached. The cleaning fabric is constructed such that the woof threads protrude from the surface of the fabric more than the warp threads. The cleaning fabric has a tape-like shape, the lengthwise direction of which is the direction of the extension of the warp threads. Soiling is removed from a connecting end face as the connecting end face and cleaning fabric are moved relatively such that the connecting end face moves transverse to the woof threads of the cleaning fabric. A method of cleaning a connecting end face uses a cleaning fabric with woof threads protruding from the surface of the fabric more than the warp threads and the fabric is moved relative to the connecting end face transverse to the woof threads of the fabric.

Abstract: A cleaner for an optical fiber connector which is made up of an elongated inner guide member having a base and an end tip, around which a cleaning member extends along the extension axis thereof, from the base to the end tip and returning again to the base; a sliding member supported so as to be slidable along the inner guide member and having a pair of guide parts that guide the cleaning member, which can slide between a projected position protruding beyond the end tip of the inner guide member and a retracted position retreating beyond the end tip, such that when the sliding member is in the projected position, the cleaning member is positioned extending around the sliding member instead of around the end tip of the inner guide member; and a tubular shaped external guide member that supports the sliding member and encloses the inner guide member and the cleaning member.

Abstract: Disclosed are a hot-melting acrylonitrile (AN) polymer composition comprising a non-volatile component modified from AN alone or a AN monomer composition through chemical reaction, an AN polymer and water, a method for producing the composition, and a method for producing a shaped article of AN polymer by melting the composition under heat followed by shaping the melt. The composition and the shaped article do not contain toxic AN and AN monomer mixture.

Abstract: A process for producing a homogeneous phase melt of polyacrylonitrile suitable for extrusion molding and melt spinning, by the steps of preparing polymer/water crumb containing 30-60 wt % of polyacrylonitrile and dewatering the crumb in a molten state with stirring at temperatures above 140.degree. C. and at pressures above autogenous pressure until the concentration of the polymer in the crumb exceeds 70% by weight.

Abstract: Saturated or superheated steam, or an inert gas, or a combination thereof is introduced into a gas phase above a molten acrylonitrile polymer in a vessel having a stirrer, while the polymer has a temperature of at least 120.degree. C. and a pressure at least equal to its autogenous pressure. Any unreacted acrylonitrile monomer, or both any such monomer and any acrylonitrile monomer or water used as a plasticizer are removed by evaporation from the vessel.

Abstract: A continuous heat treating machine for synthetic fiber tow provides a method for maintaining pressure having excellent stability on maintaining the pressure inside of the pressure chamber while avoiding quality deterioration and while ensuring minimum leakage of steam for heating medium. The length and breadth dimensions of the exit pressure seal part are set to be narrower than those of the entrance pressure seal part. The method ensures minimum damage on heat treating fiber, gives minimum unit requirement of steam for heating medium, and offers a stable operation and uniform heat treatment.
