20120148838 | METHOD FOR CONNECTING REINFORCING FIBER BUNDLES, METHOD FOR PRODUCING LONG FIBER REINFORCED THERMOPLASTIC RESIN PELLET, AND WOUND BODY - A method for connecting a tail end portion of a reinforcing fiber bundle of a preceding wound body to a front end portion of a reinforcing fiber bundle unwound from a new wound body by blowing pressurized air to both of the ends to unravel and entwine both of the reinforcing fiber bundles, wherein the method includes a preparation step for adjusting the amount of a sizing agent contained in the front end of the reinforcing fiber bundle unwound from the new wound body and the tail end of the preceding wound body to not less than 0 wt % and not more than 4 wt %, and the reinforcing fiber bundles are connected after the preparation step. It is thus possible for the reinforcing fiber bundle at the time of producing a long fiber reinforced thermoplastic resin pellet that is a material for the pellet to have a required connection strength, and to avoid the occurrence of interruption due to breakage, and accordingly allowing improvement in the production efficiency of the long fiber reinforced thermoplastic resin pellet, etc. | 06-14-2012 |
20120269024 | KNEADING SEGMENT AND KNEADING EQUIPMENT - A kneading segment kneads materials such that insufficiently kneaded portions would not remain as gel. The kneading segment is rotatably disposed on a kneading screw housed in a barrel having an inner cavity, and is provided with a kneading flight which kneads the material in the barrel by rotating according to the kneading screw's rotation. The top surface of the kneading flight is formed with a concaved cutout section. The cutout section is surrounded by two side surfaces, which face the axial direction, and a bottom surface, which is disposed between the side surfaces. The bottom surface of the cutout section is formed in a tilted planar shape in relation to the top surface. The opening of the cutout section, which faces one side of the rotational direction of the kneading screw, has a larger area than the opening which faces the other side. | 10-25-2012 |
20120315463 | LAMINATED SHEET AND COMPOSITE FORMED ARTICLE USING THE SAME - Disclosed are: a composite formed article which is usable even in a high-temperature environment and less suffers delamination between a foamed resin sheet and a metal sheet; and a formed article precursor (laminated sheet) which enables the manufacture of the composite formed article. The laminated sheet includes a foamable resin sheet containing a resin and a foaming agent; and, provided on both sides of the resin sheet, a pair of metal sheets each through the medium of an adhesive. The resin has a melting point of 145° C. or higher, and the adhesive has a melting point substantially equal to or higher than the melting point of the resin. | 12-13-2012 |
20130276421 | FIBER-REINFORCED STRAND AND METHOD OF MANUFACTURING A FIBER-REINFORCED STRAND - In a method of manufacturing a fiber-reinforced strand, the fiber-reinforced strand is so manufactured that the cross-section thereof becomes as circular as possible. The present invention concerns a method of causing a reinforced fiber bundle | 10-24-2013 |
20140366347 | IMPREGNATED-YARN CLOTH AND PROCESS FOR PRODUCING IMPREGNATED-YARN CLOTH - A process for producing an impregnated-yarn cloth which is woven fabric configured of impregnated yarns, which has satisfactory shaping properties and, despite this, has a fine texture of the reinforced fiber bundles, and which gives a molded object having excellent strength. The process for producing an impregnated-yarn cloth ( | 12-18-2014 |
20150138907 | MEMBER IN CONTACT WITH RUBBER MATERIAL - The present invention provides a member in contact with a rubber material, the member being characterized in that the member has a surface in contact with the rubber material, and that the contact angle of the surface thereof in contact with the rubber material is 40° or more when a liquid rubber to be tested is placed on the surface. | 05-21-2015 |

20100065009 | PISTON AND METHOD FOR MANUFACTURING THE SAME - The present invention reduces weight while assuring required rigidity of a piston reduces cost of the piston. A piston includes first and second pin bosses supporting a piston pins, a first side wall coupling the first pin boss and a piston skirt, a second side wall coupling the second pin boss and the piston skirt, and a pair of bridges coupling the first and second side walls and forming upward spaces just above. First and second through holes are formed in the first and second side walls. The first and second through holes and the upper spaces are formed by a single punching process using a punch and, simultaneously, the bridges are formed. | 03-18-2010 |
20140083220 | INTERNAL COMBUSTION ENGINE AND BACKLASH ADJUSTING DEVICE OF CAM DRIVING GEAR MECHANISM - An internal combustion engine includes, among other things, a backlash adjusting device. An eccentric supporting shaft is disposed in an internal combustion engine so as to be able to be fixed at a predetermined rotational angle position about a central axis. The shaft adjusts an amount of clearance between a pair of gears, and is fitted over a base shaft fixed to the internal combustion engine such that the central axis of the eccentric supporting shaft coincides with an axis of the base shaft. An adjusting portion allows an inner circumference of the eccentric shaft to be fitted over an outer circumference of the base shaft at a predetermined rotational angle position. A fixing portion is configured to fix the eccentric supporting shaft to the base shaft. | 03-27-2014 |
20140290620 | OIL PASSAGE OF INTERNAL COMBUSTION ENGINE - An oil passage of an internal combustion engine including a crankcase, a cylinder block integrally connected to the crankcase, a piston operatively mounted within the cylinder block, a piston jet for providing oil to the piston within the cylinder block and a breather device integrally formed on the cylinder block wherein the breather device is in communication with the inside of the crankcase. An elevation of temperature of the oil which flows in an oil supply path is prevented thus allowing oil in the oil supply path to maintain a low temperature wherein the oil in the supply path is supplied to a piston jet formed on the internal combustion engine. An oil supply path through which oil is supplied to the piston jet is integrally formed on a wall body exposed to ambient air on a peripheral wall which forms the breather device. | 10-02-2014 |
20140296029 | POWER UNIT FOR MOTORCYCLE - A power unit for a motorcycle includes an internal combustion engine with a transmission having an input shaft and an output shaft. A clutch with a hydraulic cylinder is provided for changing over the connection/disconnection of power transmission between a crankshaft and the input shaft. A cylinder support member, mounted on the engine body, includes a cylindrical case portion where a portion of the hydraulic cylinder is housed. The power unit can be miniaturized by suppressing the projection of the hydraulic cylinder from the engine body in the axial direction. A cover member is mounted on the engine body for covering and surrounding a projecting end portion of an output shaft from an engine body. A cylinder support member is mounted on the engine body such that a portion of a case portion is arranged in an opening portion formed by cutting away a portion of the cover member. | 10-02-2014 |
20150184690 | STRUCTURE OF CRANKSHAFT FOR INTERNAL COMBUSTION ENGINE - A crankshaft for an internal combustion engine can be an integrated crankshaft in which a thrust receiving surface is formed on each of crank arm parts around the root of a crankpin in an annularly protruding manner to restrict axial movement of a connecting rod. A recessed portion is formed in each of the facing surfaces of facing crank webs at a position near a corner portion continuing from the crankpin to the crank arm part, the position being so close to the crankpin that part of the thrust receiving surface is cut away. | 07-02-2015 |
