| 20080244029 | DATA PROCESSING SYSTEM - A transmission cancellation section is provided on a bus connecting a master and a slave. During a reset of the master, the transmission cancellation section blocks the bus so that an invalid command flowing on the bus does not reach the slave and executes, instead of the master stopped by the reset operation, generation of data which corresponds to an access request command already output to the slave and is to be sent to the slave and receiving of data from the slave. | 10-02-2008 |
| 20090031101 | DATA PROCESSING SYSTEM - Before arbitration is performed in an arbitration section, an access from a master is kept in a waiting state until update of a conversion table buffer is performed, and an address conversion section is provided in a subsequent stage of the arbitration section. Without waiting for the completion of buffer update, an access is issued in advance at a time when it is assured that update is completed at the completion of address conversion. Thus, influences of waiting buffer update on another master can be eliminated and access latency can be reduced. | 01-29-2009 |
| 20090125738 | DATA PROCESSING APPARATUS - An access stop control apparatus is provided in a resource control apparatus so that reception of access from a master apparatus is temporarily stopped during changing of a clock frequency and the clock frequency is changed at safe timing. Thereby, the operation of the master apparatus does not need to be stopped during changing of the clock frequency and a period for which access to a resource is stopped can be suppressed. Therefore, execution of an application requiring real-timeness is not affected. | 05-14-2009 |
| 20090282270 | MEMORY CONTROL DEVICE - A clock enable (CKE) control circuit ( | 11-12-2009 |
| 20110055443 | MEMORY CONTROL APPARATUS AND INFORMATION PROCESSING APPARATUS INCLUDING THE SAME - Provided is a memory control apparatus including: a monitoring unit that monitors, for each of the masters, a usable bandwidth indicating an amount of memory access data to be accessed per unit time in response to a corresponding one of the access requests from the master; a holding unit that holds a predetermined request bandwidth for each of the masters; a bandwidth determining unit that determines whether or not the usable bandwidth has reached the predetermined request bandwidth for each of the masters; and a control unit that issues an advanced refresh command to the memory based on a result of the determination by the bandwidth determining unit for each of the masters, regardless of timing of a refresh cycle. | 03-03-2011 |

| 20100050960 | COOLING APPARATUS FOR INTERNAL COMBUSTION ENGINE, METHOD OF CONTROLLING THE SAME, AND HYBRID VEHICLE INCLUDING THE SAME - A cooling apparatus for an internal combustion engine includes an engine cooling system that includes a water jacket, a radiator, and a circulation passage through which a coolant is circulated between the water jacket and the radiator, wherein the coolant is provided in the engine cooling system; a water pump that forcibly circulates the coolant provided in the engine cooling system when the water pump is operated; a reservoir tank in which the coolant is reserved, and into which gas flows from the engine cooling system while the reserved coolant flows out to the engine cooling system from the reservoir tank; and a forcible introduction portion that forcibly introduces the coolant from the reservoir tank into the engine cooling system before the internal combustion engine is started. | 03-04-2010 |

| 20080231036 | Seatbelt retractor - A seat belt retractor includes a seat belt winding device for winding up a seat belt by actuation of a motor and a control unit. The control unit, under a predetermined condition, repeats a process of stopping the actuation of the motor when an overload of the motor is detected and restarting the actuation of the motor after a lapse of a predetermined time period. The control unit includes a timer for clocking the time period from the start to the stop of the actuation of the motor, a counter for counting up the number of times of starting the actuation of the motor, and a determination module that based on the result of the timer and the counter determines whether or not actuation of the motor, which is stopped by the detection of an overload, is to be restarted. | 09-25-2008 |
| 20080238076 | Seatbelt retractor - A seat belt retractor includes a seat belt winding device for winding up a seat belt by actuation of a motor and a control unit that repeats a process of stopping the actuation of the motor on an overload of the motor and restarting actuation of the motor after lapse of a predetermined time period. The control unit includes a detection module for detecting an occupant getting on or off a vehicle and a determination module that, using criteria, determines whether or not actuation of the motor is to be restarted. The criteria when the occupant enters the vehicle is different from when the occupant exits the vehicle. The criteria are provided so that the determination module is more likely to determine that the actuation of the motor is not to be restarted when the occupant enters the vehicle as compared to when the occupant exits the vehicle. | 10-02-2008 |
