20120045968 | SUBSTRATE POLISHING METHOD AND DEVICE - A substrate polishing method includes starting to rotate a circular substrate and polishing an inner peripheral edge surface of a center circular hole formed in the circular substrate into a chamfered or rounded surface by pressing the inner peripheral edge surface against a bypass polishing part of a polishing tape that is conveyed intermittently or continuously and by oscillating the bypass polishing part of the polishing tape about a direction perpendicular to a direction that the center circular hole penetrates through the circular substrate. The polishing tape is guided so as to have an advancing portion advancing toward the circular substrate, a returning portion returning from the circular substrate, and a turning-back portion between the advancing portion and the returning portion guided along a side bypass. The bypass polishing part of the polishing tape is the turning-back portion of the polishing tape. | 02-23-2012 |
20150056893 | METHOD FOR POLISHING BALL SCREW AND BALL SCREW POLISHING APPARATUS - A method for polishing a ball screw comprising a screw shaft defining a screw axis. The screw shaft is formed with a screw groove. The method comprises the steps of: rotating the screw shaft at a rotational speed about the screw axis; conveying a polishing tape having a polishing portion traveled around an outer peripheral surface of a pressing roller, the press roller being configured to rotate about a rotational axis; guiding the polishing tape such that the polishing portion is traveled around the outer peripheral surface; pressing the polishing portion against the screw groove; tilting the pressing roller such that the rotational axis is aligned with a lead angle; oscillating the pressing roller linearly along the rotational axis; moving the polishing tape at a moving speed in a direction parallel to the screw axis; and synchronizing the rotational speed with the moving speed based on a lead. | 02-26-2015 |

20100031777 | ORE TREATING METHOD, ORE TREATING APPARATUS, IRON MANUFACTURING METHOD, AND IRON AND STEEL MANUFACTURING METHOD - An ore containing crystal water (bond water) is heated to dehydrate the crystal water in the form of water vapor, thereby rendering the ore porous to generate a porous ore. Next, the porous ore is forced into contact with a dry-distilled gas (organic gas) obtained by dry-distillation of an organic substance such as wood and the like or an organic liquid such as tar and the like. An organic compound such as tar and the like contained in the dry-distilled gas or organic liquid adheres to the surface of the porous ore. Next, the porous ore adhered with an organic compound is heated at 500° C. or higher, to generate an ore in which a part of an oxide of an element such as iron and the like contained is reduced by carbon in the organic compound. | 02-11-2010 |

20090084992 | METHOD FOR GENERATING EXTREME ULTRAVIOLET RADIATION AND AN EXTREME ULTRAVIOLET LIGHT SOURCE DEVICE - To achieve pulse-stretched EUV radiation without putting a large heat load on electrodes or requiring sophisticated control, a pulsed power is supplied between a first electrode and a second electrode provided inside a chamber to form a narrow discharge channel therebetween. A laser beam from a laser source irradiates high temperature plasma material to form low temperature plasma gas having an ion density of approximately 10 | 04-02-2009 |
20090127479 | EXTREME ULTRAVIOLET LIGHT SOURCE DEVICE AND A METHOD FOR GENERATING EXTREME ULTRAVIOLET RADIATION - High temperature plasma raw material is added drop-wise, for example, and evaporated by irradiation with a laser beam. The laser beam passes through a discharge area between a pair of electrodes and irradiates the high temperature plasma raw material. Pulsed power is applied to the space between the electrodes in such a way that discharge current reaches a specified threshold value at a time when at least part of the evaporated material reaches the discharge channel. As a result, discharge starts between the electrodes, plasma is heated and excited and then EUV radiation is generated. The EUV radiation thus generated passes through a foil trap, is collected by EUV radiation collector optics and then extracted. The irradiation of the laser beam allows setting of the space density of the high temperature plasma raw material to a specified distribution and defining of the position of a discharge channel. | 05-21-2009 |
