| 20090006893 | Information processing apparatus, diagnosis method, and computer program product - A logical central processing unit (logical CPU) selects a target device. When the target device is shared by another logical CPU, the logical CPU determines whether the logical CPU is in charge of exclusively making diagnosis of the target device. When the target device is not shared by another logical central processing unit or when the logical CPU is exclusively in charge of making diagnosis of the target device, the logical CPU makes diagnosis of the target device and stores a result of diagnosis in a storage unit. | 01-01-2009 |

| 20110228685 | WIRELESS NETWORK CONTROL DEVICE, WIRELESS NETWORK CONTROL METHOD, AND WIRELESS NETWORK CONTROL SYSTEM - A buffer has a predetermined storage capacity, and accumulates data received from an external device. A transmitting unit reads data from the buffer and transmits the data to a mobile terminal. A transmission rate determining unit determines the transmission rate for transmitting data from the external device to its own device, based on the free space in the buffer. The window size notifying unit notifies the mobile terminal of a window size in accordance with the determined transmission rate. | 09-22-2011 |

| 20100223775 | METHOD FOR DISMOUNTING ELECTRONIC DEVICE - A method for dismounting an electronic device that is mounted on a printed board by solder including heating the electronic device by dipping the electronic device in inert liquid heated in a heating bath and melting the solder in the through-hole using heat transferred from the electronic device. The electronic device has a terminal pin disposed in a through-hole of the printed board extending from a front surface to a back surface of the printed board. The terminal pin is joined to the printed board by the solder. | 09-09-2010 |
| 20100254426 | HEAT SINK FOR MEASURING TEMPERATURE OF ELECTRONIC COMPONENT - There is provided a heat sink for measuring temperature of electronic component. The heat sink includes a heat radiating plate, a fin, a heat receiving plate, and a temperature detector. The heat radiating plate has a first surface that receives heat from the electronic component. The fin is for radiating heat energy conducting through the heat radiating plate and is connected to the heat radiating plate. The heat receiving plate arranged apart from the heat radiating plate has a second surface movable to be parallel to the first surface. The temperature detector that detects a temperature is disposed on the heat receiving plate. | 10-07-2010 |
| 20110072655 | METHOD OF SOLDERING AN ELECTRONIC COMPONENT - A soldering method of an electronic component includes inserting pins of the electronic component into through-holes provided in a printed circuit board; preheating interiors of the through-holes with an inert fluid; and bonding the pins to the through-holes by exposing molten solder to the preheated through-holes. | 03-31-2011 |
