    Abstract: PROBLEM TO BE SOLVED: To obtain a uniform and good bonded state in a laminated surface, in laminating first and second base material through a laminating material, by together using pressure due to substantially uniform surface pressure and pressure due to high surface pressure in a peripheral edge part. SOLUTION: When the operation switch 16 of a pressure laminating machine 1 is operated after a laminated product 8 is set on a receiving stand 9, air- pressure PA is supplied to the upper part of a cylinder 4 and the top plate 4 fixed to a rod 4' falls and a uniform pressure fixed form material 11 or a frame material 13 approaches the upper surface of the first base material 5 of the laminated product 8. Next moment, the peripheral edge part of the laminated product 8 is held to surface pressure higher than that of other part by a frame material 13 and lamination advances. A part other than the peripheral edge part is elastically deformed on the upper surface of the base material 5 in such a form that the fixed form material 11 conforms to the wall thickness change of a second base material and uniformly pressed in a state slightly lower than the peripheral edge part in surface pressure and lamination advances.

    Abstract: PURPOSE: To reduce consumed power and prolong the life at high temperature by forming on inner and outer peripheral surfaces of an outer cylinder a covering layer that comprises a high melting point material having a specific melting point and a specific thermal expansion coefficient, and introducing inactive gas between a muffle and a furnace shell to press a muffle outer peripheral surface with specific pressure. CONSTITUTION: A resistor heater 2 is disposed outside a graphite muffle 1 perpendicularly to a muffle axis, and the muffle 1 is heated with radiation heat from the resistor heater 2 to heat string stripes T therein. Coating layers 4a, 4b are formed on inner and outer peripheral surfaces of a graphite outer cylinder 3, each of which layers comprises a high melting point material having a melting point of 2800 deg.C or higher and a thermal expansion coefficient higher than that of the outer cylinder 3 and lower than twice that of the same. Inactive gas G is introduced from an introduction nozzle 14 into a gap between the outer peripheral surface of the muffle 1 and the inner peripheral surface of the outer cylinder 3 to pressurize the muffle outer peripheral surface to a range of from 1kg/cm .G to 5kg/cm .G. After a water cooling support metal fitment 8 is inserted into a holder 6 through an O-ring 19, it is fixed to a side surface of a furnace wall 5 through packing 18.

CONSTITUTION:When a coating material 9 is injected in the sump 10 of the coating material surrounded by rolls 3, 4 and a side plate 5 in a reverse roll coater 2, the coating material 9 is weighed by the gap (c) between two rolls 3, 4 rotated in the same direction to be transferred to a coating roll 4 and transferred to the release paper 8 supplied from a backup roll 6 to become a sheet like film 11. At this time, the thickness (t) in the longitudinal direction of the film 11 is set by the gap (c) between the metering roll 3 and the coating roll 4 and the relative surface speed ratio of the rolls 3, 4 and the thickness in the width direction of the film is set by the positions of the leading end parts of the blades 141 to 143 of the partition plate 14 shaken by a partition plate driving means 15.

    Abstract: PURPOSE:To enhance permanent antistatic properties, extrusion processability, light screening properties and gas barrier properties by laminating an antistatic composition composed of specific amide or specific amide and other thermoplastic resin to a metal foil. CONSTITUTION:A layer of an antistatic resin composition consisting of polyether ester amide and other thermoplastic resin, pref., a polyolefinic resin is laminated to a metal foil. Polyether ester amide is a polymer wherein a polyamide component and a polyether component are bonded through an ester bond. As the metal foil, an aluminum foil is pref. used. As the antistatic resin composition, polyether ester amide can be independently used and can be also used in the form of the blend with other thermoplastic resin. The lamination form of the laminate is set to a two-layer structure wherein the antistatic resin composition layer is an auxiliary layer 2 and the aluminum foil layer is a main layer or a three-layer structure wherein the auxiliary layers 2 are laminated to both surfaces of the main layer 1.
