Abstract: PURPOSE:To remove foreign matter particles attached to a treating object and to get high removing effect in stable state over a long period without lowering the quality of the treating object. CONSTITUTION:A narrow gap 2 is formed between a pair of curved thin plates 1 placed opposite to each other. A yarn or web W to be treated is passed through the narrow gap 2 while supplying a gas to the narrow gap 2 through an air-feeding port 5 and a nozzle 6 to effect the self-excited vibration of the thin plates 1. The powder attached to the web W is removed by the vibration and recovered in a recovery tank 8.

Abstract: PURPOSE:To obtain a carbonized fiber having high physical properties and high dignity in a short time by bringing a precursor fiber bundle into contact with plural heat pipes in turn and repeatedly removing generated heat with the reaction in heat-treating of the fiber bundle under oxidizing gas atmosphere in carbonizing furnace. CONSTITUTION:Precursor fiber bundle 6 (e.g. acrylonitrile-based fiber bundle) is introduced into a carbonizing furnace 4 and heat-treated with a supplying treating gas (e.g. air) preferably heated at 200-350 deg.C, then the fiber bundle 6 is brought into contact in turn with plural heat-receiving parts 12 of heat pipes 11 composed of heat-receiving parts 12 and heat-radiating parts 13 in which an operating fluid (preferably naphthalene) is sealed, thus heat generated by the reaction is repeatedly removed to quickly and effectively perform the removing of heat generated by the reaction without requiring an excessive cooling equipment or control in the carbonizing furnace.

Abstract: PURPOSE:To obtain a molded body whose mechanical strength is comparatively high, by a method wherein a premolded body comprised of a fiber-reinforced thermoplastic resin whose reinforced resin is oriented in a specific direction beforehand is filled out into a split mold and then melting through heating and molding through pressurization are performed. CONSTITUTION:A bowl-like matter is formed along a cavity 7 with, for example, a top force 1 having a semispherical protrusion 4 and a bottom force 2 having a semispherical recessed part 5 and cylindrical recessed part 3. In this instance, premolded bodies 8, 9 comprised of a fiber-reinforced thermoplastic resin where a short-sized fiber is oriented at random and a premolded body 10 where the short-sized fiber is oriented in a lateral direction and at least an inflow quantity into the cylindrical recessed part 3 are kept formed beforehand. Then when the premolded bodies 10, 9, 8 are put on the bottom force 2 in this order and hot press is performed by moving the top force 1 downward, the major part of the premolded body 10 is caused to flow into the cylindrical recessed part 3 by converting an orienting direction of the short-sized fiber by 90 deg., the premolded bodies 8, 9 fill out into the cavity 7 and become a bawl-like molded body. A molded body whose mechanical strength is high can be obtained like this.

Abstract: PURPOSE:To prevent generation of nap or fiber braking in heating and fluidizing heating medium in oven of fire-resistant treatment and treating for fire resistance by passing precursor yarn through said fluidized bed, by passing the precursor yarn over the heating medium and then passing the yarn through the fluidized bed. CONSTITUTION:Heating medium 5 in an oven treating for fire resistance 1 is heated and fluidized by acidified gas sent through a dispersing plate 8 and a heater 6. At first, precursor yarn 101 is passed over said fluidized bed 5 by guide rolls 14a and 14b, then the precursor yarn 101 is passed through said fluidized bed 5 in buried state by the guide rolls 14a and 14b in a manner of rising level 16 of said fluidized bed 5 or lowering yarn guide 26, thus the yarn is continuously and smoothly subjected to treatment for fire resistance to obtain a fire-resistant yarn 102.
