A transaction input/output CPU receives a transaction to be processed and outputs the execution result of the transaction. A plurality of processing CPUs execute the transaction according to an instruction from the transaction input/output CPU. A plurality of memory areas are related to each processing CPU and store a transaction which are inputted to the transaction input/output CPU and its execution result. A register stores a pointer for indicating an address common to the plurality of memory areas. The processing CPU reads a pointer from the register, and reads a transaction from the storage destination in memory corresponding to each processing CPU and executes it.

A two-color copying machine records an image on a recording sheet in two colors such as red and black by using thermally transferable red and black inks on ink donor sheets. The two-color copying machine includes a platen for supporting an original to be copied, a scanner unit movable reciprocally with respect to the platen for reading the original and for generating an image signal for each line which is separated into two single color image signals, each corresponding to one of the two colors, a pair of thermal heads each for selectively generating thermal pulses in response to the image signal from the scanner unit, an ink donor sheet supply assembly for supplying the thermal heads with respective ink donor sheets coated with thermally transferable inks of different colors, respectively, which can be fluidized or sublimated upon being heated, a recording sheet supply assembly for supplying a recording sheet in the vicinity of the thermal heads, a recording sheet contacting assembly for bringing the supplied recording sheet into intimate contact with a heating region of each of the thermal heads with the ink donor sheet interposed between a thermal head and an ink donor sheet, a recording sheet peeling assembly for peeling the recording sheet off the ink donor sheets after the image has been recorded on the recording sheet, and a discharge assembly for discharging the peeled recording sheet.

A power tool is disclosed, which includes a tip tool driven by an electric motor, a main body for supporting the tip tool and a dust nozzle which is provided to the main body and to which a dust bag or a dust hose is connectable. When the dust nozzle is aligned in a first direction, the dust nozzle is rotatable with respect to the main body around the first direction as a rotation center. When the dust nozzle is inclined with respect to the first direction from a first position to a second position, the dust nozzle is not rotatable around the first direction.

摘要:
A common memory protection system in an apparatus having a multiprocessor configuration in which a plurality of CPUs are connected to a common RAM via a common bus, the system has a flag control section for outputting two semaphore-flag signals showing each semaphore-flag condition when the CPU checks two semaphore-flags by accessing the corresponding two semaphore-flag addresses that have complementary address values to each other, and a memory control section that allows the CPU to access any address in the common RAM via the common bus when receiving the semaphore-flag signals, both of which indicate that access to the common RAM is enabled, from the flag control section.
摘要:
In a watchdog timer circuit for a system having a central processing unit and a storage unit, a watchdog timer is provided, which counts up to a predetermined counter value and generates an alarm signal for the central processing unit when the predetermined counter value has been reached. A reset unit is connected to the watchdog timer to periodically reset the watchdog timer in response to a first reset signal generated by the central processing unit, so that the watchdog timer is reset to an initial state. A data comparing unit is coupled to the storage unit to detect whether or not the storage unit is accessible and output a second reset signal to the watchdog timer each time it is detected that the storage unit is accessible.
