摘要:
A method for the manufacture of a fiber reinforced plastic structure, comprising the steps of winding a continuous long-staple fiber impregnated with a liquid resin around a plurality of winding jigs until the resultant bundle of resin impregnated fibers attains a predetermined thickness; setting rings tightly in place on the linear portions of the resin impregnated fiber bundle between the jigs; and moving the tightly set rings relative to the linear portions thereby wringing the resin impregnated fiber bundle and expelling bubbles entrapped within the fiber bundle.
摘要:
A process for preparing a fiber reinforced plastic structure having points of branching, which comprises the steps of, positioning pins at points of branching in the structure and repeatedly hanging and repeatedly stretching a resin-impregnated strand of continuous long-staple fibers over and between said pins, thereby completing the structure of the points of branching.
摘要:
A steering wheel core material of continuous filament FRP for vehicles which is made up of a ring, a boss positioned at the center of the ring, and spokes connecting the boss to the ring, said boss being integrally joined to a boss metal fitting. It is formed by winding resin-impregnated continous filaments in layer around the ring- and spoke-forming mold and the body of the boss metal fitting, with an elastic material interposed between the body of the boss metal fitting and the FRP.
摘要:
A core for a steering wheel made of a long fiber-reinforced resin in which a ring portion, a boss portion and a three spoke portions including a first spoke portion, a second spoke portion and a third spoke portion extending in a generally T-shaped configuration from the ring portion to the boss portion, are formed by bundles of continuous fibers reinforced with a resin. The cross-sectional area for the second spoke portion situated between the first spoke portion and the third spoke portion is made smaller than the cross-sectional area for the first spoke portion and the third spoke portion.
摘要:
A core material for steering wheels, comprising a boss equipped with sleeves in a unitary structure, each of which sleeves has a slit in the axial direction thereof, said sleeves further being packed with superposed fiber strands; a ring portion; and spoke portions which connect said ring portion to said boss and being formed by winding and stretching continuous long-staple fiber strands impregnated with a resin to form the superposed strands within said sleeves.
摘要:
A tubular fuel cell comprises a cylindrical internal electrode having electrical conductivity, a lamination of a first catalytic layer, an electrolytic layer, and a second catalytic layer laminated in that order on an outer circumferential surface of the internal electrode, and an electrically conductive exterior coil wound around an outer circumferential surface of the second catalytic layer. The tubular fuel cell further comprises an electrically conductive spacer which has an outside diameter greater than that of the exterior coil.
摘要:
In order to provide the anti-retrovirus active compound with low anti-coagulant action and low cytotoxicity, compounds comprising glycoside or the salt thereof wherein lipid is linked to position 2 of sialic acid having all hydroxyl groups at positions 4, 7, 8 and 9 completely sulfated, or KDN (2-keto-3-deoxy-D-glycero-2-nononic acid) having all hydroxyl groups at positions 4, 5, 7, 8 and 9 completely sulfated are provided.
摘要:
Provided are an airbag device and an airbag folding method capable of enhancing deployment performance of an airbag without using a separate component. An airbag includes a restraint portion to be located in front of an occupant upon inflation and deployment, a base portion connected to an inflator, a top portion to be located on a windshield W side upon inflation and deployment, and a bottom portion to be located between the occupant and an instrument panel I upon inflation and deployment. The restraint portion is folded in a belt shape with a contact surface of the restraint portion for contact with the occupant facing up to form a flap portion, and the flap portion is folded to move while turning toward the occupant upon inflation and deployment of the airbag.
摘要:
A production apparatus for a tubular fuel cell, including a first extruder that supplies a first catalyst layer material to the outer peripheral surface of a cylindrically shaped inner electrode that exhibits conductivity, thereby forming a first catalyst layer, a second extruder that supplies an electrolyte layer material to the outer peripheral surface of the first catalyst layer, thereby forming an electrolyte layer, and a third extruder that supplies a second catalyst layer material to the outer peripheral surface of the electrolyte layer, thereby forming a second catalyst layer, wherein by conducting supply of the first catalyst layer material, the electrolyte layer material and the second catalyst layer material in an intermittent manner, at least a portion of the outer peripheral surface of the inner electrode is left exposed.
摘要:
A disposable coffee pot includes a lower section containing water which is heated by an external heat source. Pre-packaged ground coffee beans are located in either the lower section or in a central section isolated from the water until the temperature of the water is elevated. When the bottom of the coffee pot is heated by a heat source, the water is allowed to boil increasing the pressure in the lower section causing that boiling water to rise out of the lower section. The hot water also ruptures a container for the ground coffee beans, or a valve separating the water from the coffee beans, to allow the hot water to contact the beans and form a coffee extract. The coffee is extracted and then accumulated in an upper section through a pipe so that it is possible to collect and drink the coffee from the upper section.
