    摘要： An improved method for encapsulating an electronic component with a highly stable protective layer is provided. Such encapsulation is carried out by injection molding about the surface of the electronic component of an encapsulant composition comprising a molten melt-processable polyester which is capable of forming an anisotropic melt phase having uniformly blended therein about 0.1 to 30 percent by weight based upon the total weight of the composition of silicone oil and/or a silicone rubber. Quality encapsulation is made possible under conditions wherein damage to the electronic component is minimized, and the resulting product is well protected without damage under a wide variety of end use conditions including variations in temperature. The process is carried out in the substantial absence of deleterious mold shrinkage and the product exhibits an extremely low linear coefficient of thermal expansion which well protects the electronic component encased therein.

    摘要： Apparatus and methods are provided for producing a long fiber-reinforced thermoplastic resin compositions by initially loosening a continuous fiber bundle by a fiber loosening device so as to form a moving web-like continuous fiber bundle. At least one side of the moving web-like continuous fiber bundle which passes through the die is coated with a thermoplastic resin melt extruded through a slit disposed in the die by an extruder. The slit has substantially the same width as that of the web-like continuous fiber bundle to provide an even supply of the resin melt in the width direction of the web-like continuous fiber bundle. A thermoplastic resin melt is supplied to the slit via a plurality of resin supply paths which are branched successively on the same plane. The resin supply paths are positioned so as to be symmetrically planar with respect to the central axis of the root paths thereof. The web-like continuous fiber bundle is impregnated with the thermoplastic resin melt and can thereafter be shaped to a final product form.
