20130177727 | METHOD FOR PRODUCING FIBER-REINFORCED PLASTIC MOLDING, PREFORM AND METHOD FOR PRODUCING SAME, AND ADHESIVE FILM - The present invention is a method for producing a fiber-reinforced plastic molding including, in the following order, the steps of: forming a preform laminate ( | 07-11-2013 |
20140261993 | METHOD FOR PRODUCING PREFORM AND METHOD FOR PRODUCING FIBER-REINFORCED PLASTIC MOLDING - A method for producing a preform for manufacture of a fiber-reinforced plastic molding. The method includes: fixing a resin-equipped film rolled out from a roll state including a release film and a fixing resin and containing a partially-cured thermosetting resin, to a surface of the dry fiber fabric rolled out from a roll with the fixing resin interposed therebetween, thereby obtaining a first dry fiber fabric; separately fixing the resin-equipped film to a surface of the dry fiber fabric rolled out from a roll with the fixing resin interposed therebetween, and detaching the release film, thereby obtaining one or more second dry fiber fabrics; and laminating the second dry fiber fabrics on a surface of the first dry fiber fabric with the fixing resin of the second dry fiber fabrics interposed therebetween. | 09-18-2014 |
20140327335 | ELECTROMAGNETIC COILS, METHOD OF MANUFACTURING SAME, AND INSULATING TAPES - An electromagnetic coil having an insulating coating formed by alternately laminating, on a coil conductor, a mica layer including mica and a reinforcing layer including fiber reinforcing material, inorganic particles and resin, wherein the inorganic particles include secondary agglomerate particles formed by agglomeration of primary particles of hexagonal crystal boron nitride. The electromagnetic coil is provided with an insulating coating that suppresses external outflow of inorganic particles and ensures favorable thermal conductivity. Furthermore, the invention also provides an insulating tape having a mica layer including mica and a reinforcing layer including fiber reinforcing material, inorganic particles and resin, which is layered on the mica layer, wherein the inorganic particles include secondary agglomerate particles formed by agglomeration of primary particles of hexagonal crystal boron nitride. This insulating tape is provided with an insulating coating that suppresses external outflow of inorganic particles and ensures favorable thermal conductivity. | 11-06-2014 |
20140367361 | GAS CIRCUIT BREAKER - A gas circuit breaker includes: a pair of electrodes provided so as to be able to come in contact with and separate from each other; and an insulating material that is placed so as to generate a decomposition gas in response to a direct or indirect action from an arc occurring between the pair of electrodes when a current is broken, wherein the decomposition gas generated from the insulating material when the current is broken is configured to be utilized for extinguishing the arc, and wherein an ablative material that does not include hydrogen atoms but has a carbon-oxygen bond in a main chain or ring part is used as the insulating material. | 12-18-2014 |
20150336335 | FIBER-REINFORCED COMPOSITE MATERIAL, METHOD OF PRODUCING SAME, AND ELEVATOR COMPONENT MEMBER AND ELEVATOR CAR THAT USE SAME - Provided is a method of producing a fiber-reinforced composite material, involving impregnating a fiber structure with a resin by using the pressure difference between a vacuum pressure and an atmospheric pressure and thereafter curing the resin, the method comprising: impregnating a mixture of a bromine-containing resin | 11-26-2015 |
20150349599 | STATOR COIL FOR ROTATING ELECTRIC MACHINE, METHOD FOR MANUFACTURING THE STATOR COIL, AND ROTATING ELECTRICAL MACHINE - A stator coil for a rotating electrical machine, the stator coil including a stator iron core and a coil formed by winding an enamel wire around a slot of the stator iron core, in which the enamel wire is covered with a cured product of a first insulating varnish containing a polyester resin and the coil is covered with a cured product of a second insulating varnish containing an epoxy acrylate resin. The stator coil for a rotating electrical machine has an insulating layer with excellent adhesive strength to prevent thermal degradation of its enamel wire and has excellent dielectric strength properties retained for an extended period of time. | 12-03-2015 |
