20080209423JOB MANAGEMENT DEVICE, CLUSTER SYSTEM, AND COMPUTER-READABLE MEDIUM STORING JOB MANAGEMENT PROGRAM - In a job management device: a request reception unit stores job-input information in a storage device on receipt of a job-execution request; and an execution instruction unit sends to one or more job-assigned calculation nodes a job-execution instruction together with execution-resource information, and stores job-assignment information in the storage device in association with a job identifier. When the contents of the job database are lost by a restart of the job management device, a reconstruction unit collects the job-input information and the job-assignment information from the storage device, collects the execution-resource information from the one or more job-assigned calculation nodes, and reconstructs the job information in the job database.08-28-2008
20090234951CLUSTER CONTROL APPARATUS, CONTROL SYSTEM, CONTROL METHOD, AND CONTROL PROGRAM - A cluster control apparatus, cluster control system, and computer-readable recording medium are provided. The cluster control apparatus includes a switching unit that disconnects a first computer from a first group and disconnects a second computer belonging to a second group from the second group to cause the second computer to belong to the first group, when a first computer is unable to execute a job to be processed and a job executing unit that causes the second computer belonging to the first group to execute the job to be processed after the second computer have belonged to the first group by the switching unit.09-17-2009

20090274075Radio Communication Apparatus - A radio communication apparatus performing time division duplex alternately switching a transmission period and a reception period by time dividing an identical frequency, includes the steps of: detecting a transmission signal to be transmitted to the antenna so as to perform radio transmission from an antenna commonly used for transmission and reception; and calculating a deviation time between the detection timing of the detected transmission signal and a preset reference timing, and for controlling switchover timing between the transmission period and the reception period based on the deviation time.11-05-2009
20100128644Wireless Communication Device - A wireless communication device performing wireless communication by switching between transmission timing and reception timing in time division, controls to supply a heater or a fan with power supplied from a power supply unit in the reception timing period, and controls to suspend supplying the heater or the fan with the power supplied from the power supply unit in the transmission timing period, in case that a temperature detected by a temperature detector is outside a specified temperature range while a time-division switchover between the transmission timing and the reception timing is performed.05-27-2010

20090298446DISTORTION COMPENSATING APPARATUS, WIRELESS COMMUNICATING APPARATUS, AND DISTORTION COMPENSATING METHOD - A distortion compensating apparatus includes following units. An information measuring unit measures a distortion component and an electric power component based on a radiation signal. A compensation coefficient calculating unit calculates a compensation coefficient based on the distortion component and the electric power component. A signal transmitting unit outputs a signal corrected by the compensation coefficient as a transmission signal. A signal converting unit converts the transmission signal into a high frequency signal. An amplitude separating unit amplifies the high frequency signal and separates a portion thereof as a signal to be fed back. A feeding-back unit processes the portion and outputs the result as a feedback signal to the information measuring unit. An electric power information extracting unit outputs a portion of the high frequency signal as the radiation signal, extracts electric power information from the radiation signal, and directly outputs the electric power information to the information measuring unit.12-03-2009
