| 20110026491 | ALLOCATION METHOD AND BASE STATION APPARATUS USING THE SAME - A base station apparatus and an allocation method are provided. The base station apparatus includes an allocation unit and a communication unit. The allocation unit allocates, in a frame, different channels for data between a base station apparatus and a terminal device and control information about the data, the frame formed with a plurality of time slots being time-multiplexed, each time slot formed with a plurality of channels being frequency-multiplexed. The communication unit performs communication with the terminal device by using the control information and the data, to which a channel is allocated. The allocation unit, while securing at least the control information, releases at least one data which is not secured, and instructs the terminal device to perform handover process by using a time slot, in which no data is allocated. | 02-03-2011 |
| 20110134789 | REPORT METHOD AND ACCESS CONTROL DEVICE - It is specified that a frame containing at least the plurality of slots is repeated. A detecting unit detects a slot usable in the communications between terminal apparatuses, from among a plurality of slots. A modem unit and an RF unit broadcast the information on the detected slot. A power measuring unit in the detecting unit measures the respective received powers of the plurality of slots, and an empty slot identifying unit identifies a slot whose received power is less than a threshold value. | 06-09-2011 |

| 20080265552 | Airbag device - An airbag includes two base cloths sewn together at their outer peripheries by a seam extending from a central portion to the outer periphery of the base cloths into a vortical shape. When gas is supplied from an inflator to a center aperture of one of the base cloth to inflate the airbag, load generated by gas pressure breaks the seam sequentially from the central portion to the outer periphery, preventing sudden deployment of the airbag in fore and aft directions at the initial stage of deployment, thereby enabling not only soft restraining of passengers but also sufficient restraining by deploying the airbag into a final shape that is flat in fore and aft directions upon completion of breaking of the seam. The seam comprises a plurality of bonding portions such that the inflation breaks each of the bonding portions sequentially. | 10-30-2008 |
| 20100253054 | AIR BAG SYSTEM FOR VEHICLE - An air bag system for a vehicle including an air bag in a folded state and installed in a vehicle. The air bag is inflated and expanded by gas from an inflator, which introduces gas into the air bag. A vent hole is formed in at least one base fabric piece of the air bag so as to establish a communication path between an inside and an outside of the air bag through which gas may be discharged from the inside toward the outside of the air bag. A blocking member is supported on the base fabric piece to block up the vent hole. A guide portion is provided to slidably support the blocking member and to restrict the position of the blocking member relative to the vent hole. A sliding resistance increasing portion is provided on at least either one of the guide portion and the blocking member, so as to increase a sliding resistance between the guide portion and the blocking member when the blocking member slides. | 10-07-2010 |

| 20090296536 | MAGNETIC DISK DEVICE - The magnetic disk device is capable of securely removing contaminations from an outer face of a magnetic head, maintaining superior recording and reproducing characteristics and improving reliability. The magnetic disk device comprises: a ramp for holding a magnetic head at an evacuating position, the ramp being located outside of a region in which a magnetic recording medium is provided; and a laser emitting section for emitting a laser beam toward the magnetic head so as to heat the magnetic head, the laser emitting section being located in a moving track of the magnetic head, which is moved between the evacuating position and a loading position, without interfering with the magnetic head. An air stream generated by rotation of the magnetic recording medium removes contaminations from the magnetic head when the magnetic head is loaded. | 12-03-2009 |

| 20080239550 | Head slider, magnetic storage device and control circuit, having cleaning mechanism - The present invention relates to a head slider used for a magnetic storage device. In accordance with an aspect of the present invention, a head slider having an air bearing surface comprising, a heater element disposed at the air bearing surface, and at least one groove formed in an end surface at a trailing edge side of the head slider so as to extend toward a rear surface. | 10-02-2008 |
| 20090034111 | Magnetic head having track width expansion mechanism, magnetic storage device and control circuit - The present invention generally relates to a magnetic head and a magnetic storage device using a recording medium. More particularly, the present invention relates to a magnetic head for expanding the track width of the recording medium, a control circuit for controlling the magnetic head, and a storage device that uses the magnetic head and the control circuit. The magnetic head includes a slider, a read element disposed on the slider, and a heater element disposed closer to the leading edge side of the magnetic head than the read element in a position opposite to a recording medium. | 02-05-2009 |
