  • Publication number: 20120224221
    Abstract: A non-transitory computer readable recording medium that stores a print management program causing a computer to function as a retrieval unit that retrieves information about first functions of an image forming device and information about second functions of plural second devices; and a determination unit that determines whether the second functions of the second devices can process a print job, when the first functions of the image forming device cannot process the print job. Here, the image forming device and the second devices are connected to a print system including the computer. When the determination unit determines that the second functions of the second devices cannot process the print job, the print management program constrains the second functions of the second devices from being utilized.

  • Patent number: 7536534
    Abstract: A processor has an instruction set A and an instruction set B. A system instruction decoder decodes a system instruction that specifies the operating mode of the processor, the system instruction not being included in either the instruction set A or the instruction set B. A system instruction execution controller receives a decoded signal from the system instruction decoder, which has decoded an instruction requiring changeover of the instruction set, and sets the value of a instruction mode register. On the basis of the value in the instruction mode register, an instruction set changeover unit selects the instruction set to be used.

  • Publication number: 20090085626
    Abstract: When a master circuit is in an inactive state, a slave circuit assigned to the master circuit is not used. Accordingly, the use efficiency of system recourses is decreased. To solve the above problem, a semiconductor integrated circuit reassigns a M2 region of a slave circuit, previously assigned to a first master circuit, to a second master circuit. That is to say, the M2 region of the slave circuit previously assigned to the first master circuit is reassigned to the second master circuit based on the operational status of the first master circuit. This improves the use efficiency of system resources of the semiconductor integrated circuit.

  • Patent number: 7159582
    Abstract: In an internal combustion engine for a vehicle having a drive clutch, a blowby control system includes a fresh air introducing channel, for introducing fresh air into a crankcase, and a blowby gas return channel for returning blowby gas from the crankcase to an air-intake system. A blowby control valve is provided in the fresh air introducing channel or the blowby gas return channel, for selectively restricting gas flow through the blowby system. A controller is also provided on the vehicle for controlling operation of the blowby control valve. The controller is programmed to switch the blowby control valve from the closed state to the open state, with the drive clutch connected, when the vehicle starts traveling. The blowby control system and method hereof can reduce variations in the engine speed occurring during engine idling and before clutch engagement, to improve ride quality of the vehicle.
