20090047428 | METHOD FOR MANUFACTURING CARBON FIBROUS STRUCTURES - Disclosed is a method for manufacturing carbon fibrous structures each of which comprises a three dimensional network of carbon fibers, which is characterized in that, in the procedure of carbon fiber vapor phase deposition utilizing decomposition of organic carbon compound, at least two kinds of organic carbon compounds as carbon sources are in existence at least at predetermined thermal decomposition reaction temperature range in a reaction furnace and partial pressures of gases of these compounds are regulated so that these compounds are decomposed at mutually different decomposition temperatures, and/or a raw material gas supplied into the reaction furnace is forced to form a turbulent flow. It is possible to obtain efficiently the carbon fibrous structures each of which comprises a three dimensional network of carbon fibers and which are suitable as additives to be added to solid materials, such as resin, ceramics, metal, etc., to improve physical properties, such as electric, mechanical, or thermal properties, of the solid materials, and also as additives to be added to liquid materials, such as fuels, lubricant oils, and etc., to improve physical properties, such as thermal property, of the liquid materials. | 02-19-2009 |

20140147543 | FLUID PRESSURE IMPRINTING DEVICE PROVIDED WITH PRESSURIZATION UNIT SECURING TOOL - An imprinting device is provided which is capable of using small an opening/closing device even when a transfer area increases. The imprinting device that transfers a molding pattern of a die to a molding target includes a pressurization unit that includes a pressurization chamber to pressurize the die and the molding target by a fluid, a stage that supports the die and the molding target pressurized by the pressurization unit, a pressurization device for adjusting the pressure of the fluid inside the pressurization chamber, an opening/closing device for relatively moving the pressurization unit and the stage, and a securing tool that secures the pressurization unit and the stage so as to prevent or suppress an application of force generated by the pressurization unit to the opening/closing device. | 05-29-2014 |
20140319718 | IMPRINTING DEVICE AND IMPRINTING METHOD - An imprinting device to transfer the mold pattern on a die to a molding target includes a casing forming a pressure-adjusting chamber, a stage supporting the die and the molding target, a frame encircling a circumference of the stage, first moving means moving the casing and the stage in a direction coming close to each other or becoming distant from each other, second moving means moving the casing and the frame in a direction coming close to each other or becoming distant from each other, pressure-adjusting means that adjusts the pressure of a fluid in the pressure-adjusting chamber, and decompression means which decompresses a decompression chamber formed by the stage, a frame, and the die or the molding target, and which eliminates a fluid present between the die and the molding target. | 10-30-2014 |
20150042013 | IMPRINT DEVICE AND IMPRINT METHOD - An imprinting device having a stage and a cover that depress the die and the molding target, a frame formed with a hole into which the stage is fitted and surrounding an outer circumference thereof, a first moving means for relatively moving the stage and the cover in a direction coming close to or becoming apart from each other, a second moving means for relatively moving the cover and the frame in a direction coming close to or becoming apart from each other, a first depressurizing means for depressurizing a depressurizing room formed any one of the cover, the die or the molding target, and the stage, and further the frame, and eliminating a fluid between the die and the molding target, and a second depressurizing means for eliminating a fluid in a space between the cover and the die or the molding target. The imprinting device can be thus downsized and costs can be reduced. | 02-12-2015 |
20150091220 | Molding Method And Molding Device - A shaping method and a shaping device are provided which can easily and inexpensively form a curved face in a film including a micropattern. A shaping method is for forming, in a predetermined shaping-target area of a film including a patterned face with a micropattern, and a rear face opposite to the patterned face, a curved face beyond the thickness of the film, and includes a fixing step for fixing an outer edge of the shaping-target area of the film by fixing means, a first heating step for heating the film | 04-02-2015 |
20150158239 | IMPRINT DEVICE AND IMPRINT METHOD - An imprint device and an imprint method which form mold patterns on both surfaces of a molding target. An imprint device transfers mold patterns on both surfaces of a molding target using flexible first and second dies and includes first and second casings which each apply pressure of first and second pressurizing rooms respectively, to the first and second dies respectively and the molding target, a pressurizer that adjusts the pressures of the pressurizing rooms, first and second moving units that move the first and second dies respectively and the molding target in a direction coming close to or distant from each other, a depressurizer that depressurizes a depressurizing room formed between the first and second casings, and eliminates fluids present between the dies and the molding target, and a pressure adjuster that adjusts pressures to reduce pressure differences between the depressurizing room and the pressurizing rooms. | 06-11-2015 |
20150217506 | Roller Pressing Device, Imprinting Device, and Roller Pressing Method - A roller-type depressing device, an imprint device and an imprint method utilizing the same which can depress an object like a die or a molding target by controlling the depressing force of a roller is provided. A roller-type depressing device to depress the object with a roller includes a pressure adjusting plate provided with the roller, a roller moving unit moving the roller relative to the object, a pressure adjusting unit holding the pressure adjusting plate in such a way that force produced by a pressure difference in fluid applied to both faces of the pressure adjusting plate acts on the roller, a pressure receiving stage receiving the pressure of the roller via the object, and a pressure adjuster adjusting the pressure difference in fluid applied to both faces of the pressure adjusting plate. | 08-06-2015 |
