    摘要： The method of manufacturing a film of thermotropic liquid crystal polymer includes extruding a thermotropic liquid crystal polymer of a kind in which any one of activation energies Ea1 and Ea2 of a melt viscosity is within the range of 30 to 90 kcal/mol, with the ratio (Ea1/Ea2) of the activation energy Ea1 relative to the activation energy Ea2 being within the range of 1 to 1.7. The activation energies Ea1 and Ea2 are measured by means of a capillary rheometer, including a nozzle of 1 mm in inner diameter and 10 mm in length disposed at an angle of introduction of 90° and a barrel of 9.55 mm in inner diameter, at respective shear rates of 243 seconds−1 and 2432 seconds−1 under a temperature ranging from the temperature [(Tm−10)° C.], which is lower by 10° C. than the melting point [(Tm)° C.] of the thermotropic liquid crystal polymer, to the temperature [(Tm+20)° C.], which is higher by 20° C. than the melting point [(Tm)° C.] of the thermotropic liquid crystal polymer. The thermotropic liquid crystal polymer also has a melt viscosity of not lower than 400 poises measured under predetermined conditions, and is extruded from a die that is heated to a temperature of predetermined range.

    摘要： A screw conveyor apparatus including a ribbon screw (4) provided in a cylindrical casing (1). The ribbon screw (4) has rotation rings (12) attached to an intermediate portion thereof. Outer peripheral supporting sections (11) are provided for rotatably supporting the corresponding rotation rings (12) on the casing (1). This configuration prevents the ribbon screw (4) from being bent or expanded under a load of conveyed materials, thereby enabling the materials to be conveyed along a steep slope up to a high portion.

    摘要： An earth removing apparatus for a shield tunneling machine comprising a tubular casing having an excavated earth inlet at one end and a closable outlet for excavated earth at the other end, and a double-shaft screw conveyor rotatably supported by the casing at two portions. The screw conveyor is supported on the casing in the vicinity of its earth inlet by an annular member fitted in an annular recess in the casing, with a bearing provided between the annular member and the casing. Since the forward end of the screw conveyor need not be supported at the center of rotation of the cutter head of the tunneling machine, the apparatus can be designed with greater freedom and is free of objections in its mechanical structure.
