摘要:
Sheet molding compounds which comprising two layers, one being a sheet molding compound layer containing a hollow, lightweight filler particles (referred to as Type A layer) and the other being another type of sheet molding compound layer not containing lightweight, hollow filler particles (referred to as Type B layer), with the above-mentioned Type A and Type B layers making up a consistently integrated structure.
摘要:
Ultravioletsetting resin composition contains fragmentary quartz glass powder in the ratio of 50 to 200 parts to 100 parts of the ultravioletsetting resin. The surface hardness of the ultravioletsetting resin of the present invention is increased in a short time by the application of ultraviolet rays.

A resinous cylinder comprises a cylindrical portion with an open end and a closed end, and is formed by flowing raw material of resin from the center of the closed end. A first attaching portion is disposed at the side of the open end of the cylindrical portion and has a hole for securing to a vehicle body. A flange portion has a second attaching portion disposed at the side of the closed end. The second attaching portion has a hole for securing the resinous cylinder to the vehicle body. A resin flowing portion is formed between the second attaching portion and the closed end of the cylindrical portion. A connecting portion connects the first attaching portion and the second attaching portion through a clearance with the cylindrical portion. A volume of the flange portion is reduced so that a resin flowing speed of the flange portion is faster than a resin flowing speed of the cylindrical portion. The first attaching portion, the flange portion and the connecting portion are integrally formed with the cylindrical portion.
摘要:
A fiber-reinforced plastic product comprises a first member which is formed by pressing from a sheet molding compound made of an unsaturated polyester resin and having a first portion which should be reinforced and a second portion having an area adjacent to the first portion, a second member made of a uni directional sheet molding compound made of the unsaturated polyester resin, including a bundle of glass fibers which is continuously formed so as to be arranged in the same direction, and overlayed on the first portion by the press formation, and a concave portion formed in the area. Thereby, the second member is prevented from expanding along the first member during the press formation.
摘要:
A weather strip for a door belt-molding disposed for sliding contact with a window glass to prevent water leakage between the door belt-molding and the window glass, comprising a root portion of which at least one portion is made of a material having a high coefficient of elasticity and resistance to permanent strain. The preferred materials are ethylene propylene rubber or a thermoplastic elastomer resin.
摘要:
A compact-size variable resistance device has a terminal for electrical connection to an external device, a resistor that slidingly contacts with a brush, and connecting parts formed of an electro-conductive resin containing a thermoplastic resin. The electro-conductive resin connecting parts readily make reliable electrical interconnection of the terminal and the resistor when the connecting parts are joined by, for example, ultrasonic bonding.
摘要:
A composite molded article which is produced by joining multilayer boards composed of fiber-reinforced thermoplastic resin onto the surface of a core material made of a foamed resin, and its production method. The composite molded article is constituted by a core material which is composed of a foamed resin molded into a desired shape, and the multilayer boards which are produced such that a plurality of prepregs containing reinforcement fiber by a volume content of not less than 30% and not more than 85% are laminated with the direction of the reinforcement fiber being different with respect to each other, and are heated to not less than a melting temperature of a thermoplastic resin contained therein so as to mutually glue the prepregs, and to remove air contained inside. When the composite molded article is produced, the multilayer boards having been molded into shapes adapted to a shape of the core material are heated to not less than the melting temperature of the thermoplastic resin and are pressed and glued to the core material to make the composite material article.
摘要:
A vibration wave motor includes a stator with an upper surface at which is generated a travelling vibration, a rotor with a lower surface rotatably mounted on the upper surface of the stator, and an urging device for developing a frictional force between the upper surface of the stator and the lower surface of the rotor. A sheet member is attached to either the upper surface of the stator or the lower surface of the rotor and the sheet member includes a base member having ultra heat-resistant properties, a fluorine-contained resin and a filler in the form of fibers.
摘要:
An article, obtained by injection molding, includes a first member on which an electrical element such as a coil is provided or mounted and a second member, surrounding the first member, formed integrally therewith. A first radially inward projection of the second member is in abutment with a first annular flange of the first member. A second radially inward projection of the second member is fitted in and welded to a vee on the first annular flange. Such weld acts as a seal for water-proofing the electric element. For preventing separation of weld due to repetition of radial expansion of electrical element upon current application thereto, a connecting means is provided between the first radially inward projection and the first annular flange.
摘要:
A front end module structure of a vehicle comprises a front end panel mounted on front side members of the vehicle, the front end panel including a metal-made upper reinforcement extending in the widthwise direction of the vehicle and having a horizontally thrown U-shaped, or closed, sectional configuration and a resin-made main body formed integrally with the upper reinforcement and so formed on the upper reinforcement that a part thereof may intrude into the sectional configuration thereof, the resin-made main body having formed therein at least a retaining portion, by which a radiator is retained, and an upper reinforcement portion fixed to front fender reinforcements of the vehicle. As a result of this, there is enhanced the rigidity of the upper reinforcement portion of the front end panel.
