摘要:
The method of forming a light-weight, fiber-reinforced, particularly glass fiber-reinforced-thermoplastic resin product includes the steps of melting and mixing thermoplastic resin pellets containing parallely oriented fibers 2-100 mm long, injecting the melted resin into a cavity which is closed so that its volume is smaller than that of the final molded product, and, before or after the resin injection is completed, opening the cavity until its volume is equal to that of the final molded product. Unlike the conventional injection-molded products, this product does not require a foaming agent and, if it uses any, requires only a small amount of foaming agent. The product thus formed is light in weight and has fibers uniformly entangled inside, providing an excellent appearance of the surface. Further a skin layer is formed over the surface. These features combined with the reinforcement by the glass fibers offer high strength and high stiffness.

Disclosed is a method of molding a fiber-reinforced resin laminate which can manufacture a lightweight laminated molding having excellent mechanical characteristics regardless of the shape of a molding, which can readily unite a surface coat material and a molding while the surface coat material is held in good condition, and which can impart excellent appearance to a laminated molding. Also disclosed is a laminated molding manufactured by the method. The method uses a molding material which contains fiber-containing thermoplastic resin pellets which, in turn, contain reinforcing fibers having a length of 2 mm to 100 mm. The reinforcing fibers account for 5% to 70% by weight of the molding material. A molten resin obtained through the plasticization of the molding material is injected into a die, onto which a surface coat material for covering the surface of a molding is previously attached. After injection of the molten resin into the die cavity is started, a movable die is advanced so as to compress the molten resin contained in the die cavity, followed by expansion of the volume of the die cavity to that of an intended molding.

The present invention is directed to a method of obtaining a gas-introduced fiber-reinforced resin injection molding and to a molding obtained by the method. According to the present invention, there can be obtained a lightweight gas-introduced fiber-reinforced resin injection molding containing glass fibers or like fibers having excellent rigidity and strength and improved surface properties. The method includes the steps of: injecting into a die a molten resin obtained through the plasticization of a molding material; and introducing gas into the molten resin, the molding material comprising fiber-containing thermoplastic resin pellets which contain reinforcing fibers having a length of 2 mm to 100 mm, the reinforcing fibers accounting for 5% to 70% by weight of the molding material, the die including a movable die capable of advancing into and retracting from the internal cavity of the die, wherein after the injection of the molten resin into the die cavity is started, the movable die is retracted to a position where the die cavity assumes a volume corresponding to the molding, and gas is introduced into the molten resin filling the die cavity.

Disclosed is a glass fiber reinforced polyolefin resin composition comprising 15-80% by weight of polypropylene, 20-60% by weight of polybutene-1 and 5-60% by weight of glass fiber. This resin composition is excellent in the balance of impact strength, stiffness, heat distortion temperature, surface hardness and processability. When this composition is molded, the molded products have no surface roughness and no color shade and have good appearance. The properties are further improved when a modified polyolefin alone or together with a crystal nucleating agent are added.

A health food product in the shape of a hamburger sandwich does not include bread but rather comprises a combination of: a food material having as the primary component thereof a tofu product prepared by kneading tofu containing 65 to 90% water content well, forming a patty of a predetermined size, and deep frying the patty in oil at a temperature of 165 to 190° C.; and a filling including vegetables, seaweed, meat, fish, shellfish, legumes/beans/seeds/nuts other than soy beans, eggs, dairy products, and oils and fats. The food material is sliced in the same way as with a bun so as to hold the filling, and may also include ingredients selected from vegetables, seaweed, meat, fish, shellfish, legumes/beans/seeds/nuts other than soy beans, eggs, dairy products, and oils and fats.

An enema has liquid amount controlling component, namely a rotary valve, having an outer tube with a cylindrical concave part at its center and is provided with an insertion opening fitting a connecting tube and a discharge opening fitting a conduit on a side wall of the concave part of the outer tube. A rotator is provided with opening parts corresponding to the positions of the insertion opening and the discharge opening of the outer tube, and a knob part on an upper part of the rotator. Two fitting spring are integrally formed to extend on both sides of a fixture (8), and the fixture has a penetration hole for inserting a beak tube. The fixture slides on the said beak tube for controlling the length of the beak tube to be inserted into an anus. The rotator rotates in the outer tube according to the operation of the knob part of the rotator, and an amount of an injection liquid in a tank to be injected into the anus from the beak tube via the conduit is controlled according to the relationship between the opening parts of the rotator and the insertion opening and the discharge opening of the outer tube based on the rotation of the rotator.
摘要:
Even when being released in a region from a lower small intestine to a large intestine with various coatings, bisacodyl is inadequately effective because of its hardness to dissolve due to its poor solubility, and thus a more drug should be contained. In the related art, there have been no techniques for allowing bisacodyl and dioctyl sodium sulfosuccinate to be simultaneously released in a region from a lower small intestine to a large intestine. A solid formulation having a core particle containing bisacodyl and dioctyl sodium sulfosuccinate coated with an enteric coating which allows the drugs to be released in a region from a lower small intestine to a large intestine can be used as an excellent pharmaceutical product.
