摘要:
The present invention provides a method for manufacturing laminated material which can remove ear portions of a resin film extruded from an extruding machine and can directly laminate the resin film to a substrate and can make the processing of end portions of a laminated material after lamination unnecessary. The present invention also provides an apparatus used for such a manufacturing method. In the method for manufacturing laminated material which laminates a resin film formed by extruding molten thermoplastic resin from a T-die to a substrate, a laminating film is formed by cutting ear portions of the resin film before lamination and the laminating film is laminated to the substrate. Further, the apparatus for manufacturing laminated material according to the present invention comprises heating means which preheats a substrate, a T-die which extrudes molten thermoplastic resin as a resin film, cutting means which forms a laminating film by cutting ear portions of the resin film before lamination, lamination rolls which laminate the laminating film to the substrate, and a cooling device which quenches the formed laminated material.

A method of producing an extrusion-laminated member comprises extruding a thermoplastic resin from a T-die into the form of a film and laminating the film on a heated metallic base member using a pair of laminating rolls, wherein a pre-roll is disposed between the T-die and one of the laminating rolls to receive the film on the side opposite to the side that adheres onto the base member over the whole width of the film. The film is wound on the pre-roll at an angle (&agr;) of from 10 to 90 degrees. The film received by the pre-roll is fed to the laminating rolls, conveyed by being supported by the laminating rolls on the side opposite to the side that adheres onto the base member, and is fed to a nipping position so as to be melt-adhered onto the heated metallic base member.

A spinning reel for fishing includes a rotor rotatably supported in a reel body, a drive mechanism for driving the rotor by operating a handle mounted on the reel body, a first reversal preventive mechanism for preventing the rotor from rotating in the direction of playing out a fishline by stopping the drive mechanism from rotating in the reverse direction at the time of casting the fishline, and a second reversal preventive mechanism for holding the rotor in a predetermined position by stopping the drive mechanism from rotating in the reverse direction. The first reversal preventive mechanism is formed of a rolling one-way clutch, and the second reversal preventive mechanism is caused to hold the rotor in the predetermined position by switching the first reversal preventive mechanism to non-working condition.

A metal film etching method etches selectively a metal film formed on a layer insulating film provided with viaholes so as to cover the surface of the layer insulating film and fill up the viaholes so that the metal film excluding portions there of filling up the viaholes are removed completely without forming a pit in the portions of the metal film filling up the viaholes. The metal film etching method uses a mixed reactive gas of a gas containing fluorine atoms, a gas containing chlorine atoms and oxygen gas.

Water-soluble high molecules are made present as a dispersing agent in a dispersion coating bath of a solution of a water-soluble nickel salt containing graphite dispersed therein, and a mold for molding a glass is immersed therein in a manner that the mold serves as the cathode and the nickel metal serves as the anode in order to effect the plating while suppressing nickel or a nickel-based alloy in the film from growing in a vertical direction or in the direction of the plane thereof. On the inner surfaces of the mold is formed a film which comprises a matrix of nickel or the nickel-based alloy which as a whole has a flake-like form that is continuous and exists in an open cellular form and a graphite granule phase which is held in the open cells and is outwardly exposed on the surface. Since nickel is suppressed from growing like granules, the film exhibits excellent lubricating property, heat resistance, parting property, abrasion resistance and durability in combination, and is free from defects inherent in the prior art.

A photoelectric conversion apparatus includes a pair of opposite electrodes, and an amorphous silicon film. The amorphous silicon film is sandwiched between the pair of opposite electrodes and serves to perform photoelectric conversion of light including light from a target object. At least one of the pair of opposite electrodes is divided into a set of pattern electrodes respectively connected to the amorphous silicon film in electrically positive and negative directions so as to form a spatial filter electrode. The respective pattern electrodes respectively connected in the positive and negative directions are irregularly arranged on the amorphous silicon film.
