20080217806 | Continuous molding method of composite material having stepwise sectional thickness - There is provided a continuous molding method capable of varying a thickness of a prepreg molded article. | 09-11-2008 |
20090239018 | PREPREG PEEL PLY FOR CONTINUOUSLY FORMING COMPOSITE MATERIAL - The invention provides a prepreg peel ply to be laminated on a surface of a composite material prepreg for forming a member having a concaved portion such as an H-shaped member, wherein the prepreg peel ply is peeled off after performing hardening so as to improve the adhesiveness of the surface of the composite material. A prepreg peel ply impregnated with resin having a hardening property substantially equivalent to that of the composite material prepreg is used as the peel ply to be laminated on a surface of the composite material prepreg. Through use of such prepreg peel ply, it becomes possible to apply a continuously formed prepreg material to form members having concaved portions, such as H-shaped members, and to form excellent members without voids. By using polyester or nylon as fiber material contained in the prepreg peel ply, the peel property can be improved, and the surface of the composite material prepreg will have a desirable roughness after peeling off the prepreg peel ply, according to which the adhesiveness of the surface is enhanced. | 09-24-2009 |
20090243151 | METHOD FOR CONTINUOUSLY PREFORMING COMPOSITE MATERIAL IN UNCURED STATE - The invention provides a method for continuously preforming a prepreg material impregnated with thermosetting resin in an uncured state. A sheet of prepreg material is drawn out from a roller, laminated, and bent into a given cross-sectional shape via a bending device. The prepreg material is then continuously formed via a mold having a heater into a long product. The heat and pressure applied to the prepreg material in the mold is selected from a heating temperature that does not completely cure the thermosetting resin and a pressure range enabling the prepreg material to maintain the formed state. The above-mentioned preforming method enables to form members having a loose curvature (for example, a radius of 7 m or smaller) or stringers having a continuously varied curvature. | 10-01-2009 |
20150158281 | CONTINUOUS PREFORM DEVICE FOR COMPOSITE STRINGER - A continuous preform device for a composite stringer continuously preforms the composite stringer having three-dimensional curved surfaces in an efficient manner, the continuous preform device including a dispenser device | 06-11-2015 |

20130116054 | VIBRATION DUMPING DEVICE - A vibration damping device capable of reducing a change in an order frequency of a reciprocating motion of a pendulum resulting from eccentricity of rotational members therein. The vibration damping comprises a pendulum damping mechanism having a mass to dampen the torsional vibrations by an oscillating motion thereof resulting from the torsional vibrations. An inertial body is arranged in the prime mover side of the rotary shaft, an elastic damping mechanism is connected with a transmission side of the inertial body in a power transmittable manner, a pendulum damping mechanism is connected with the transmission side of the elastic damping mechanism in a power transmittable manner, and a torque limiter mechanism is connected with the transmission side of the pendulum damping mechanism in a power transmittable manner. | 05-09-2013 |
20130186724 | Vibration Damping Device - To provide a simply-structured vibration damping device having excellent vibration damping capacity. | 07-25-2013 |
20140352290 | TORSIONAL VIBRATION DAMPING DEVICE - A torsional vibration damping device that can ensure a space for allowing a mass body to make reciprocating movements and can improve the vibration damping performance is provided. A torsional vibration damping device in which a mass body is attached to a rotating body by two support pins includes two first hollow portions which are formed in the rotating body at positions corresponding to the respective support pins and into which the respective support pins are inserted, and two second hollow portions which are formed in the mass body at positions opposed to the respective first hollow portions and into which the respective support pins are inserted. Outer sides of inner peripheral edges of the respective first hollow portions in a radial direction of the rotating body serve as guide faces. Inner sides of inner peripheral edges of the respective second hollow portions in the radial direction of the rotating body serve as attachment faces. The guide faces and the attachment faces are formed as recessed curved faces. A distance between centers of curvature of the guide faces is shorter than a distance between centers of curvature of the attachment faces. | 12-04-2014 |

20150276014 | TORSIONAL VIBRATION DAMPING DEVICE - The present invention relates to a torsional vibration damping device in which a contact site with an inertial mass can be lubricated effectively while reducing resistance of the inertial mass to oscillate. The vibration damping device includes a rotary member that is rotated by a torque, and an inertial mass that is oscillated by torque pulses. The inertial mass is held in a chamber formed on the rotary member liquid-tightly together with lubrication oil while being allowed to be oscillated by torque pulses in the rotational direction of the rotary member. An amount of the lubrication oil is adjusted in a manner such that the inertial mass will not be brought into contact with an oil film of the lubrication oil centrifugally adhering to a radially outer section of an inner face of the chamber. | 10-01-2015 |
