20100314056 | PROCESS FOR PRODUCTION OF BLEACHED PULP - Provided is a process for producing bleached pulp, including subjecting unbleached pulp, which is obtained by cooking a lignocellulose substance, to alkali-oxygen bleaching treatment and then subjecting the alkali-oxygen bleached pulp to chlorine-free bleaching treatment including chlorine dioxide treatment, wherein in at least one chlorine dioxide treatment stage in which the chlorine dioxide treatment is performed, monopersulfuric acid is used in combination. The amount of chlorine dioxide to be used is reduced and the colour reversion resistance of the bleached pulp is improved by this process. | 12-16-2010 |

20090273426 | Coil component and method for producing the same - A coil component having a core, first and second terminal electrodes provided on the core, and a conducting wire having a winding portion provided on the core and end portions electrically connected to the first and second terminal electrodes to provide first and second connecting portions. The core has one side surface at which the first and second connecting portions are provided. When viewing the one side surface, a wire portion in the winding portion extends in a first direction, and a wire portion extending from the second connecting portion extends toward the winding portion in a second direction. The first and second directions define an intersection angle of not more than 90 degrees. | 11-05-2009 |

20090236725 | Solder Preform and Electronic Component - An electronic component having a semiconductor element bonded to a substrate with solder has a decreased bonding strength if there is not a suitable clearance between the semiconductor element and the substrate. Therefore, a solder preform having high melting point metal particles dispersed in solder has been used in the manufacture of electronic components. However, when an electronic component was manufactured using a conventional solder preform, there were cases in which the semiconductor element leaned or the bonding strength was not adequate. | 09-24-2009 |

20090031925 | Gas-Forming Agent For Cement Composition - [Problem to be Solved] To provide a gas-forming agent which exhibits no hydrogen embrittlement and allows gas generation to achieve a desired amount of inflation even in the presence of nitrite, and a cement composition utilizing the agent which offers improved shrinkage compensation. | 02-05-2009 |
20140061455 | IMAGE QUALITY ADJUSTING METHOD, NON-TRANSITORY COMPUTER-READABLE RECORDING MEDIUM, AND ELECTRON MICROSCOPE - In accordance with an embodiment, a method of adjusting quality of an image of patterns common in shape includes acquiring a first gray value and a first waveform within a reference image, acquiring a sample image, acquiring a second gray value and a second waveform from third and fourth regions within a sample image, respectively, and adjusting the brightness and contrast of the sample image. The first gray value is a standard for the brightness of the image from a first region within a reference image. The first and second waveforms represent a luminance profile of second and fourth regions including edges, respectively. The third and fourth regions correspond to the first and second regions. The brightness and contrast of the sample image are adjusted by matching the first gray value and the first waveform with the second gray value and the second waveform. | 03-06-2014 |

20090014092 | PROCESS FOR PRODUCING A SOLDER PREFORM HAVING HIGH-MELTING METAL PARTICLES DISPERSED THEREIN - [Problems] A conventional process for producing a solder preform in which a predetermined amount of high-melting metal particles are directly put into molten solder and stirred, requires a long time for dispersing the high-melting metal particles by stirring. Therefore, in the conventional method for producing a solder preform, dissolution of the high-melting metal particles into the molten solder occurred during stirring, and their particle diameters became small. If a semiconductor chip and a substrate are soldered with a solder preform containing metal particles having such decreased diameters, the space between portions being soldered becomes narrow, and a sufficient bonding strength is not obtained. | 01-15-2009 |

20080277207 | Machine Room-Less Elevator - A machineroom-less elevator in which a counterweight is vertically moved behind a cage, with the cage and the counterweight being suspended in a jig back manner through a first and second diverting sheaves. In this machineroom-less elevator, a sufficiently large vertical stroke of the counterweight can be secured, while a durability of a hoist rope is improved. In addition, since no tensile difference is generated in respective parts of the hoist rope, vertical vibrations of the cage are prevented when the cage restarts a vertical movement. A traction sheave is disposed on one of right and left sidewalls of an elevator shaft. A first diverting sheave is disposed below and sufficiently apart from the traction sheave, and a second diverting sheave is disposed on a top of a rear wall of the elevator shaft. The traction sheave is disposed to be inclined relative to the sidewall such that a rotational axis thereof extends from the sidewall of the elevator shaft to the rear wall thereof, when viewed vertically from above. | 11-13-2008 |
