20090204981 | CLUSTER SYSTEM, SERVER CLUSTER, CLUSTER MEMBER, METHOD FOR MAKING CLUSTER MEMBER REDUNDANT AND LOAD DISTRIBUTING METHOD - A protocol process to a reception traffic is executed by cluster members of a current use system and a backup system. The backup system discards the reception traffic subjected to the protocol process and only the current use system transfers the reception traffic to an AP. The AP makes an application process redundant in an independent method. The cluster member in charge of the protocol process to the reception traffic is determined by using a data in a lower layer and the cluster member in charge of the application process is determined by using a data in a higher layer after the protocol process. | 08-13-2009 |

20100175123 | ADDRESS TRANSLATION DEVICE AND ADDRESS TRANSLATION METHOD - In order to more efficiently use port resources, which are finite global address resources assigned to an address translation device, the address translation device holds a session-port assignment table showing a correspondence between an existing session and a local endpoint (port resource) in the address translation device, and a port assignment rule indicating port usage about assignable ports. An address translation unit translates address information of a packet received according to the correspondence between the existing session and the port resource shown in the session-port assignment table, and assigns the port according to the port usage indicated by the port assignment rule for a packet for opening a new session. An assignment rule update unit changes a ratio of the port usage in the port assignment rule while the correspondence between the existing session and the port resource in the session-port assignment table is not changed. | 07-08-2010 |

20110215619 | SEAT BACK FRAMEWORK - In an upper frame member of seat back framework, an upward-slippage prevention portion is simply defined to prevent a seat occupant's back portion from being slipped or dislocated on and along a seat back in the case of rear-end collision. The upward-slippage prevention portion has a sloped region for receiving the seat occupant's back portion which is to be slipped or dislocated on and along the seat back under inertia when a rear-end collision occurs and thereby preventing an undesired upward slippage or dislocation of that seat occupant's back portion which will result in damage of his or her neck or cervical vertebrae. | 09-08-2011 |
20120153658 | VEHICLE SEAT - A vehicle seat, including two links movable for adjustment in height of the seat, is provided with a reinforcing transmission shaft. The reinforcing transmission shaft is rotatably connected between two frame members of seat cushion frame in the seat, while extending through the two links. Further, two pinions are fixed on the respective two end portions of the reinforcing transmission shaft and respectively meshed with two gear portions defined in the respective two links. With such arrangement, in the case of rear-end collision, most of great load applied to the links is transmitted, via the reinforcing transmission shaft, pinions and gear portions, to each of the two frame members, thereby preventing deformation of one of the two links to avoid lowering of the seat or inclination of one side of the seat as found in a rear-end collision case. | 06-21-2012 |
20120153702 | SEAT CUSHION OF VEHICLE SEAT - A seat cushion of vehicle seat including a seat cushion frame and a bottom panel member on which a foam padding is mounted. The bottom panel member has a thigh support area fixed to a forward portion of the seat cushion frame and a buttocks support area situated in a rearward portion of the seat cushion frame. The buttocks support area has a resiliently deformable area in which are formed beads, each being resiliently stretchable laterally relative to the central line thereof by a downward load applied to the buttocks support area, whereby the resiliently deformable area is rendered deformable and displaceable downwardly. The buttocks support area may be made narrow by forming two inwardly curved edge portions in the respective sides thereof to thereby allow that buttocks support area to be warped downwardly. Hence, the buttocks support area is resiliently displaceable vertically relative to the seat cushion frame. | 06-21-2012 |
20120181825 | SEAT BACK FRAMEWORK - A shoulder receiving portion is defined in each of two lateral frame members of seat back framework of vehicle seat in order to receive two shoulder portions of seat occupant in the case of rear-end collision, prior to a seat occupant's back portion being moved close to an upper frame member of the seat back framework. The shoulder receiving portion is therefore arranged in an upper region of each of the two lateral frame members so as to project forwardly from a plane where the two lateral frame members lie, and the upper frame member is formed in substantially “inverted-U” shape and inclined backwardly distant from the two lateral frame members, This arrangement avoids unpleasant pressed touch to be given to the seat occupant's back portion in the case of rear-end collision and may prevent a great impact from being imparted to vertebrae of the seat occupant. | 07-19-2012 |
