Abstract: A kneading apparatus includes a barrel having a chamber, which is a tubular hollow, a biaxial screw set for extruding a material to be kneaded downstream by rotation of the biaxial screw set inside the chamber, and kneading blade sections, mounted in the screw set, for kneading the material by shearing the material in tip clearances and a wedge-shaped space between an inside wall of the chamber and the kneading blade sections. The tip clearance becomes narrower from the upstream side to the downstream side in the direction of extrusion of the material. The kneading apparatus, which performs a continuous kneading operation, makes it possible to set proper kneading conditions in accordance with changes in the state of a material being continuously kneaded, and achieves high kneading efficiency.

Abstract: A continuous kneading apparatus and method are provided wherein discharge ports are provided at a plurality of positions of the barrel to discharge a kneaded product, and one of the plurality of the discharge ports is selected according to a desired kneading condition so as to discharge the kneaded product from only the selected discharge port. Another continuous kneading apparatus and method are provided wherein a plurality of charging ports are provided at a plurality of positions of the barrel to supply a material to be kneaded into the chamber, and one of the plurality of charging ports is selected according to a desired kneading condition. The kneading apparatuses and methods permit adjustment and control of a viscosity and a dispersion degree of a compounding agent over a wide range, and continuous kneading to achieve significant rationalization of a process for producing a kneaded product.

Abstract: A kneading apparatus includes a barrel having a cylindrical chamber; a screw assembly rotating in the chamber so that a material to be kneaded is extruded in the axial direction by the rotation, the screw assembly including a screw section having helical blades and a kneading blade section in order to allow the material to flow into the clearance between the inner wall of the chamber and the kneading blade section, and to apply shearing forces to the material; a metering feeder for feeding the material at a substantially constant volumetric or gravimetric rate into the chamber; an injecting device for injecting a heat-removing medium into the chamber; and a discharging device for separating the heat-removing medium from the material and discharging the heat-removing medium from the chamber. A kneading method using the kneading apparatus is also disclosed.

Abstract: The paint masking tape comprises a substrate, an adhesive layer formed on one side of the substrate, and a backing resin layer formed on the back surface of the substrate. Here, the backing resin layer contains a urethane resin and an epoxy resin or a compound containing aziridine ring(s). The paint masking tape does not tear easily when peeled off from a paint object, inhibits the flaking-induced scattering of paint flakes, and provides clearly visible parting lines.

Abstract: When any of the functions: copier function, printer function and facsimile function, are not being performed, the function information display portion provides display messages ‘Copier available’, ‘Printer available’ and Fax available’, using the display areas equal in size, arranged in the vertical direction. When a print request is given from an external apparatus, the function information display portion provides a display message ‘Printer function engaged’ along with the image processing operating conditions and provides display messages ‘Copier function partly available’ and ‘Facsimile function partly available’ in the left and right halves of the display section. While the printer function is in progress, the information relating to the printer function is displayed in the display area four times as large as that for the copier function and that for the facsimile function.

Abstract: A coat masking tape base material and a coat masking tape, having superior follow-up properties, promising sharp paint lines and being free of "left-on" when peeled, in which a polyolefin resin film having a modulus of elasticity of from 15 to 55 kgf/mm.sup.2 has been subjected to modification treatment on its both sides, and a pressure-sensitive adhesive layer maintaining a thermoplastic saturated block copolymer, a thermoplastic unsaturated block copolymer and a tackifier or a cross-linked acrylic pressure-sensitive adhesive layer is formed on the film having been subjected to modification treatment.

Abstract: A direct driven shock ripper device according to the present invention is capable of efficiently transferring blows of a hydraulic breaker (10) to a base rock. It includes a bracket (2) which can be affixed to the rear end of a construction machine vehicle, a beam (4) on which a shank (8) and a breaker mount bracket (9) supporting the hydraulic breaker (10) are mounted, the beam (4) being disposed to the rear of the bracket (2), an arm (6) which couples a lower portion of the bracket (2) to a lower portion of the beam (4), a tilt cylinder (5) which couples an upper portion of the bracket (2) to an upper portion of the beam (4), and a lift cylinder (16) which couples an upper portion of the bracket (2) to a lower portion of the beam (4). A pair of link members (7) are provided between the beam (4) and the shank (8) to pivotally support the shank (8) on the beam (4) and thereby form a quadric linkage.

Abstract: An adhesive composition comprised of a nitrile rubber having carboxyl groups and a polyamide resin derived from polymeric fatty acids and alkylene polyamines. Such adhesive compositions are useful upon sheet members of plasticized polyvinylchloride, among other possible uses.
