An extruder includes a barrel and a kneading screw extending through the barrel in a rotatable fashion. The kneading screw is provided with a devolatilization portion. The devolatilization portion includes a kneading flight that is twisted in a direction for transferring a material downstream. The kneading flight kneads the material while transferring the material downstream and separates a volatile component from the material. Impregnation sections, which allow the kneading chamber to be impregnated with the material, are respectively disposed adjacent to an upstream side and a downstream side of the devolatilization portion so that the air-tightness of the devolatilization portion of the extruder is maintained. Accordingly, an efficient devolatilization operation of the material is achieved.

An object of the present invention is to provide a bladder which is unlikely to have a shapal variation along the inner wall surface of the tire and can satisfactorily extend along the inner wall surface of the tire. An inventive bladder is used to press the inner wall surface of the tire by a pressurized heating medium during the vulcanization of a green tire and is comprised of a fabric layer (purl stitched fabric layer 12) and rubber layers (silicone rubber layers 11, 13) placed one over another. Elongation rates of the fabric layer in warp direction and in weft direction both exceed 15% and satisfy: 0.4≦elongation rate in weft direction/elongation rate in warp direction ≦6.0. Since the fabric layer has good extensibility, it can elongate with the rubber layers.

摘要:
A resin coated metal plate having excellent formability comprises, on a metal plate, a resin coating layer containing a conductive filler and a corrosion inhibitor, a matrix resin constituting the resin coating layer is made mainly of a flexible epoxy resin and has a modulus of elasticity of not less than 3 GPa. When secondarily cured, the resin coated metal plate is imparted with excellent weldability and corrosion resistance.

A panel structure for a transport machine is disclosed which is constituted by an integral combination of an outer panel and an inner panel. The inner panel has reinforcing protuberances and recesses, possessing a higher rigidity than the outer panel. The protuberances of the inner panel and a back side of the outer panel are bonded together through insulating layers present on the protuberances.

The apparatus of the invention is an injection molding apparatus of a type adapted to cool a molten metal under shearing by an extrusion screw in a substantially vertical chamber into a semi-solidified slurry and then inject the semi-solidified slurry discharged from a discharge port at the lower end of a channel into molding plates, in which a clamping device is adapted to open or close a movable plate relative to a stationary plate in the horizontal direction, and a connection member having, at the inside, a vertical first channel and a second channel extending in the horizontal direction from the lower end of the first channel and in communication with the stationary plate is connected to the discharge port at the lower end of the chamber. Since this can inject and mold light metal molding products of high quality with less pore or shrinkage without excessively enlarging the size for the height of the apparatus, casting products of high quality can be obtained at a reduced cost by injection molding.

In the case of thickening a feed resin without pre-drying, a device is taught to enhance the thickening effect. The device includes a chamber 4 having a mixing rotor therein for continuously mixing a resin between a feed port 2 and a discharge port 3. A plurality of vent ports 7 connected to vacuum pumps 8, 9 are provided for reducing the pressure in the chamber. An element, e.g. a screw feeder 10, is provided for introducing a viscosity-increasing chemical agent into the chamber. The screw feeder is isolated from the reduced pressure areas of the chamber by elements 35, e.g. reverse screw flights of the rotor. In operation, feed resin from a hopper 6 enters the chamber through port 2 and is dehydrated while being continuously mixed in a drying section 14 via vents 7. After addition of the chemical agent, the resin is continuously mixed in a thickening section 15 while being deaerated.
