Abstract: The present invention introduces a plurality of resource management devices (M1)-(M4). Each resource management device comprises a resource reservation information transmitting unit (205) and a resource reservation information receiving unit (206). Thus, even when one of the resource management devices is inactivated, the resource management can be continued. Since reserved resource information is shared among a plurality of resource management devices, if exist, the resource management can be performed without contradiction. Processing load can be decentralized by processing a resource reservation request by the plurality of resource management devices.

Abstract: In a braking/driving force control apparatus, a vehicle target braking/driving force and a vehicle target yaw moment through the control of braking/driving forces of wheels are calculated, and when the target braking/driving force and the target yaw moment cannot be achieved through the control of the braking/driving forces of the wheels, the vehicle target braking/driving force after the modification and the vehicle target yaw moment after the modification are calculated such that, within the range where the ratio of the vehicle target braking/driving force after the modification and the vehicle target yaw moment after the modification coincides with the ratio of the target braking/driving force and the target yaw moment, the vehicle braking/driving force and the vehicle yaw moment by the target braking/driving forces of the wheels take the greatest values.

Abstract: A variable valve timing mechanism-equipped engine is provided which allows a mount installing section and a hydraulic control valve of a variable valve timing mechanism to be positioned in a chain case without limitation of positioning of accessories such as a water pump, air conditioning compressor, power steering oil pump and alternator, and which simplifies an operating oil passage for the hydraulic control valve. In the variable valve timing mechanism-equipped engine, a mount installing section is positioned below an actuator cover section and is offset toward one side with respect to a cylinder axis, and intake- and exhaust-side hydraulic control valves are disposed sideward of the mount installing section with axes inclined toward a direction perpendicular to the crankshaft axis, the intake- and the exhaust-side hydraulic control valves overlapping one another.

Abstract: Access points for supporting wireless communications, a packet transmission device, and terminals for handing-over between service areas are provided. An existing terminal is provided with respect to this access point for performing a Quality of Source (QoS) guarantee. Accordingly, when a new terminal is handed over to be engaged in wireless communications with this access point, the priority of the packet associated with the existing terminal and/or new terminal is changed.

Abstract: The communication system supports reservation of network resources. The base stations relay packets among the terminals, and perform priority control based on the priority set to the packets. In the terminal, the communication-managing table stores communication information of own terminal and a partner thereof. The packet-transmitting unit, setting priority to the packets, transmits the packets. When link condition of own terminal change, the link-managing unit updates, in order to prevent from quality deterioration of the other terminals, the priority of each of the packets whose source terminal is the own terminal.

Abstract: The invention provides a semiconductor device having less defectives in shape of a patterned wiring layer even in a case of having a wiring layer for which patterning is required to be carried out over a longer period of etching time, and a method for producing the same. By carrying out dry etching using a fluorine-based gas with a photoresist 17a used as a mask, an auxiliary mask 15a is formed by patterning the insulation membrane. Next, by carrying out dry etching using a chlorine-based gas using the auxiliary mask 15a and the remaining photoresist 17a as masks, wiring 13a is formed by patterning the wiring layer 13. In the second etching, the auxiliary mask 15a is scarcely etched. Therefore, if the thickness of the photoresist 17a is equivalent to that in the prior arts, it is possible to pattern a thicker wiring layer 13 than in the prior arts.

Abstract: A valve gear for an internal combustion engine capable of promptly switching the position of a piston in a rocker arm to thereby change the engine operating condition with a satisfactory response, even in a low rotation region in which an adequate amount of oil discharged from an oil pump cannot be expected. Depending on positions of pistons slidably fitted in low-speed and high-speed cylinder portions provided in an intake driven rocker arm, a low-speed or high-speed drive rocker arm is selectively operated to press a corresponding one of the pistons. The piston in the low-speed cylinder portion switched in a low rotation region is made smaller in diameter than the piston in the high-speed cylinder portion, to be enabled to be promptly switched.

Abstract: Access from a terminal of an outside network to a server of an inside network is put under control. A repeater and the server permit a packet transmission from the terminal to the server under limited conditions. When the server acknowledges connection for the permitted packet, the transmission conditions for packets to be sent to the server are loosened. After then, packet transmission between the terminal and the server is controlled under the loosened transmission conditions. As for encrypted packets, the server decodes the encrypted packets and notifies the relevant information to the repeater.

Abstract: A resource request is continuously accepted within predetermined time by a resource management device that comprises a resource request accepting unit, a measuring unit, and an allocating unit. The resource request accepting unit accepts a resource request that is necessary for communication. The resource request includes priority of communication. The measuring unit measures the accepting time when the resource request accepting unit accepts the resource request. The allocating unit allocates resource to the resource request accepted in accepting time based on priority. As a result, suitable resource allocation according to the priority instead of the order of arrival is realized.
