摘要:
A multilayer molded article comprising a resin body and at least one sheet of a skin material an edge part of which is present in a surface area of the resin body is efficiently produced by clamping an edge part of a skin material or mated edge parts of adjacent skin materials during molding.

The present invention provides a process for producing a multilayer molded article which includes supplying at least one piece of a skin material having a desired shape and a resin melt between unclosed upper and lower molds and closing the molds to form a multilayer molded article including the thermoplastic resin and the skin material which covers only a desired part of the article, wherein the resin melt is supplied at or near a center area of a rear face of the skin material, or wherein after the skin material is lifted to a position at which the skin material contacts a cavity surface of the upper mold by a vertically movable rod or bar which is positioned at a part of the lower mold on which the skin material is placed, the resin melt is supplied between the upper and lower molds and the rod or bar is returned to a determined position at least before the molding is completed. This process economically produces a multilayer molded article in which the skin material covers the desired part of the article without displacement and which has a good feeling.
摘要:
A hollow molded article is produced by supplying a molten resin between a pair of a fixed mold and a movable mold before the fixed mold and the movable mold are closed, inserting at least one gas-supplying pin which is provided on a surface of the fixed mold to form a hollow part in a part of the resin and supplying pressurized gas through said gas-supplying pin before the mold closing is finished, closing the movable mold to fill the resin in a cavity formed by the molds, slightly opening the molds while pressurizing a gas in the resin to expand the hollow part and opening the movable mold to remove a hollow molded article from the molds.
摘要:
A multilayer molded article is produced using a composite skin layer made of a skin material and a foam sheet on a core layer of a thermoplastic resin in which a tensile modulus E of the skin material is not larger than 950 kg/cm2, and a tensile modulus E (kg/cm2), a heat shrinkage factor F (%) and a thickness t (cm) of the skin material satisfy the following relationship: 20/(E×t)+F≧2.5, which method produces a large size multilayer molded article having a complicated shape and no wrinkles, breakage or uneven marks in the skin material on the surface of the article.

摘要:
A method for manufacturing multi-layer molded-products, including the steps of supplying molten thermoplastic resin between an upper mold and a lower mold, and applying pressure to a forming cavity by clamping in a forming process. With this method, it is possible to easily produce a multi-layer molded-product wherein the covering material, such as a woven fabric, is entangledly fused to and integrally formed on the surface of a base plate with at least one hole that is made of thermoplastic resin.

摘要:
A plastic-made reinforced structure comprising a thermoplastic resin-made plate and cylindrical hollow rib(s) made of the same resin as that of said plate, connected to at least one side of said plate perpendicularly to the side so that the plate and the rib(s) form one piece, in which structure the following relationships hold:d.sub.1 .gtoreq.20 mm,1>d.sub.1 /d.sub.2 .gtoreq.0.7,H.gtoreq.30 mm,1.gtoreq.d.sub.1 /H.gtoreq.0.3, and1>t.sub.1 /t.sub.2 >0.3wherein d.sub.1 and d.sub.2 are the inside and outside diameters of each rib at the root of the rib, i.e. the joint of the rib to the plate; H is the length of each rib from the root to the front end; and t.sub.1 and t.sub.2 are the rib thicknesses at the front end and at the root.
摘要:
An object of the present invention is to provide a technique that can facilitate setting of an object, such as a favorite team. An information output device includes a database that associates and stores a region on a map and a sport team related to the region, a position acquisition unit that acquires a position of a self-vehicle, and a favorite team setting processing unit that sets a favorite team from among sport teams. Moreover, the information output device includes a determination processing unit that specifies the region corresponding to the self-vehicle position acquired by the position acquisition unit and determines the sport team associated with the specified region in the database as an object to be set by the favorite team setting processing unit or a candidate for the object.

There is provided a device that receives a broadcast providing a data distribution service from a broadcast station, registers data related to facilities acquired through the data distribution service in a primary database, extracts from the primary database data related to facilities near the position of the host vehicle every time a host vehicle has run a predetermined distance, registers the extracted data in a secondary database, and presents data for presentation extracted from the secondary database to a user.
摘要:
An impact energy absorptive structures is made of usual plastic materials suitable for molding processing, and is designed to suit different degrees of impact loading anticipated in various applications. The impact energy absorptive structures is composed of a base member 11 and protruding rib members including long and short members, in which the proportion of the cross sectional area of the long rib members is between 0.3 to 0.8 of the total cross sectional area of the rib members. Other design modifications can be made readily to customize the impact resistance of the impact energy absorptive structures.
