Abstract: A charged-particle beam system has a demagnifying lens for reducing the dimensions of an electron beam produced from an electron beam source, an objective lens for focusing the demagnified beam onto the surface of a target, a first deflector located before the demagnifying lens, a second deflector placed such that the deflection field produced by it is totally or partially superimposed on the objective lens field, and a third deflector located in a stage following the second deflector. An image of the light source is created by the demagnifying lens. An image of the light source image is formed on the target by the objective lens.

Abstract: A preform can be molded by resin transfer molding and yields a composite material having excellent strength and excellent interlaminar debonding resistance. The preform, which is for producing a fiber-reinforced composite, comprises layers of laminated structure of a reinforcing material comprising reinforcement fibers and has, between these layers, a layer comprising a thermoplastic resin and having space so as not to inhibit a liquid resin from flowing therethrough. The preform is molded to yield a fiber-reinforced composite material.
