20100142082 | DISK DRIVE AND METHOD FOR HEAD SERVO CONTROL OF THE DISK DRIVE - A disk drive. The disk drive includes a head, a moving mechanism, a first peak filter, an adaptive peak filter, and a filter controller. The head is configured to read servo data on a disk at sampling frequency. The moving mechanism is configured to move the head in proximity with a recording surface of the disk. The first peak filter has a fixed peak frequency and a variable gain, and is configured to be inserted into a servo loop. The servo loop is configured to position the head with position error signals between servo data read by the head and a target position. The adaptive peak filter has a variable peak frequency and a variable gain, and is configured to be inserted into the servo loop. The filter controller is configured to control the gain of the adaptive peak filter according to the gain of the first peak filter. | 06-10-2010 |
20100328810 | DISK DRIVE AND SERVO-CONTROL METHOD THEREFOR - A disk drive. The disk drive includes a head, an actuator, and a controller. The head accesses a disk. The actuator is configured to support the head and to move the head by action of a voice-coil motor in a substantially radial direction of the disk. The controller is also configured to perform servo control of the actuator by using servo data read out by the head. The controller includes at least one of a plurality of notch filters having a fixed center frequency inserted in a servo-control loop. The controller is configured to increase an attenuation rate by at least one of the plurality of notch filters having the fixed center frequency at a designated frequency, when a target position of the head is at a position selected from the group consisting of a position outside of a specified region and a position within the specified region. | 12-30-2010 |
20110058276 | SERVO CONTROL OF A DISK DRIVE - A disk drive comprising a head for accessing a disk, an actuator for moving the head in the radial direction of the disk and a controller. The controller for servo control of the actuator based on servo data read out from the disk by the head. The controller is configured for maintaining a width of the adaptive chasing notch filter below a specified value in servo system control and estimating an oscillation frequency of the actuator. | 03-10-2011 |

20130034930 | APPARATUS FOR MANUFACTURING DYE-SENSITIZED SOLAR CELL, AND METHOD OF MANUFACTURING DYE-SENSITIZED SOLAR CELL - In an apparatus for manufacturing a dye-sensitized solar cell, a photosensitization dye solution makes contact with an electrode material layer that functions as a working electrode of a dye-sensitized solar cell so that the photosensitizing dye is adsorbed on the layer. Such an apparatus for manufacturing a dye-sensitized solar cell has a substrate housing section to house a substrate with the electrode material layer formed on its surface, and a circulation mechanism to circulate the photosensitization dye solution in such a way that the solution passes a surface of the substrate housed in the substrate housing section. In such an apparatus, a cross-sectional area of a flow path for the photosensitization dye solution in a portion facing the substrate in the substrate housing section is set smaller than a cross-sectional area of a flow path for the photosensitization dye solution in other portions. | 02-07-2013 |
