| 20100134918 | SERVO WRITE METHOD AND SERVO WRITE SYSTEM FOR HARD-DISK DRIVE - A servo write method for a hard-disk drive. The method includes generating, with an input of characteristics of a magnetic-recording head and a magnetic-recording disk which are incorporated into the hard-disk drive, a yield prediction model from a correlation between yields of the hard-disk drive, and characteristics of the magnetic-recording head and the magnetic-recording disk of the hard-disk drive in a process. The method also includes predicting a yield which is obtained when each magnetic-recording head is used as a position control head, selecting as the position control head a magnetic-recording head that has a highest predicted yield, and writing a servo signal. | 06-03-2010 |
| 20110072644 | METHOD AND SYSTEM FOR MANUFACTURING A HARD-DISK DRIVE - A method for manufacturing a hard-disk drive (HDD). The method for manufacturing a HDD includes writing servo tracks, and writing servo tracks into the HDD using a calculated control target value of a calculated servo pattern overlap amount. Writing servo tracks includes a first, second, third and fourth operation. The first operation includes: producing a first control equation for obtaining a servo pattern overlap amount; and, converting a root-mean-square error (RMSE) into a probability distribution. The second operation includes calculating a second control target value that results in an increased product yield, from the RMSE probability distribution. The third operation includes producing a second control equation for obtaining a calculated servo pattern overlap amount, by assigning the second control target value into the first control equation. The fourth operation includes calculating the calculated control target value using the second control equation and the magnetic-recording-head characteristic value. | 03-31-2011 |

| 20110024595 | SEAT TRACK - A lock lever bracket fixed to an upper rail and serving as a lock mechanism for locking the upper rail sliding relative to a lower rail includes shaft support holes which are separated from each other in the slide direction of the upper rail and through which an open rod is inserted. A lock lever includes two bearing portions which are disposed close to both shaft support holes of the lock lever bracket and a rotation transmission groove. The open rod includes a linear shaft portion which extends through each shaft support hole and each bearing portion and a bent portion which engages with the rotation transmission groove of the lock lever and rotates along with the linear shaft portion so as to rotate the lock lever in the unlock direction. The bearing portion of the lock lever is formed as a clip-shaped bearing portion in which a pair of plate-shaped portions is provided separated from each other in the insertion direction of the open rod, bearings are formed by bending the pair of plate-shaped portions in the opposite directions so as to interpose the open rod therebetween, and a gap between the bearings in the radial direction is smaller than a diameter of the open rod. | 02-03-2011 |

| 20090203768 | NUCLEIC ACID-CONTAINING COMPLEX - A nucleic acid-containing complex, containing a nucleic acid and a biodegradable polymer, especially a positively-charged water-insoluble biodegradable polymer, is disclosed. The complex has excellent properties of sustainedly releasing a desired nucleic acid, especially DNA, to a site in need of a treatment. Since the complex can be taken up to phagocytes such as macrophages and delivered specifically to the target site, the function of the nucleic acid can be exhibited in a target site specific manner, and thus more specific gene therapy can be achieved. The complex has no adverse effects, such as occurrence of recombinants or toxicity which could be caused by using a virus vector such as adenovirus, or liposome. Thus, the complex is particularly preferable for the field of gene therapy. Furthermore, the complex enhances the biological effect of the nucleic acid introduced into the cells, allowing a gene therapy with a lower dose of nucleic acids. | 08-13-2009 |

| 20090091635 | DISPLAY CONTROL DEVICE, DISPLAY CONTROL METHOD, AND DISPLAY CONTROL PROGRAM - A display control device includes: a composite image generating unit configured to generate a composite image by compositing a unit image and a still image, such that a still image which is correlated with a moving image and has a still image aspect ratio different from a moving image aspect ratio, is superimposed on a portion of a unit image of the moving image which is formed of multiple temporally continuous unit images having a moving image aspect ratio; and a display control unit configured to display the composite image on a display screen of a display unit. | 04-09-2009 |
| 20110043650 | IMAGING DEVICE AND IMAGING METHOD - According to the invention, extracting still and moving pictures having different aspect ratios from an original picture from within an extraction range suitable for an imaging mode can be performed. An embodiment of the invention, according to the selected imaging mode, sets the still picture extraction range with an aspect ratio of 4:3 for extracting a still picture and the moving picture extraction range with an aspect ratio of 16:9 for extracting an HD moving picture within the imaging range of the imaging device 17. Then, the embodiment, from the imaged picture, extracts a picture within the set still picture extraction range as still picture, and extracts a picture within the set moving picture extraction range as HD moving picture. That is, the embodiment can switch between the still picture extraction range and the HD moving picture extraction range having different aspect ratios according to the imaging mode. And thus, from the picture within the imaging range (i.e., the original picture), the embodiment can extract the still picture and the HD moving picture having different aspect ratios from within the extraction range suitable for the imaging mode. | 02-24-2011 |

| 20090092872 | FUEL CELL STACK AND METHOD OF PRODUCING ITS SEPARATOR PLATES - A cell of a fuel cell includes a membrane electrode assembly, and metal first and second separators which sandwich the membrane electrode assembly to form gas flow paths disposed on each side of the membrane electrode assembly. A back surface of the first separator and a back surface of the second separator, the first separator and the second separator being included in adjacent cells, are in contact with each other, thereby forming a temperature-control medium flow path between the first separator and the second separator. In the first separator and the second separator, corrosion-resistant coating layers are provided only on reaction-side surfaces of the first separator and the second separator, the reaction-side surfaces facing the membrane electrode assembly, and portions where the back surface of the first separator is in contact with the back surface of the second separator are joined by welded portions. | 04-09-2009 |
