Techniques and apparatuses for providing power-aware thread scheduling and dynamic use of processors are disclosed In some aspects, a multi-core system is monitored to determine core activity The core activity may be compared to a power policy that balances a power savings plan with a performance plan One or more of the cores may be parked in response to the comparison to reduce power consumption by the multi-core system In additional aspects, the power-aware scheduling may be performed during a predetermined interval to dynamically park or unpark cores Further aspects include adjusting the power state of unparked cores in response to the comparison of the core activity and power policy

Power-aware thread scheduling and dynamic use of processors

Turning radius is calculated from steering angles of steering-wheels and articulation angles of respective frames, and the steering-wheels are automatically rotated faster than rear-wheels based on the turning radius, the revolution number of the rear-wheels, engine speed of an engine and a speed range of hydraulic motors, so that conventional trouble for manipulating operation lever etc. while turning a motor grader and skill-requiring work for adjusting the revolution number of the steering-wheels in accordance with the revolution number of the rear-wheels can be eliminated, thereby easily and accurately controlling the revolution number of the steering-wheels and securely preventing tight-corner braking phenomenon.

To reduce power consumption of a processor system including a plurality of processors without degradation of the processing ability, a flag detecting section detects an assignment control flag and a clock control flag added to instruction code. An instruction assignment controlling section outputs the instruction code to a CPU or an HWE based on the detection to have the instruction code executed. A clock controlling section supplies a clock signal having a frequency lower than the maximum clock frequency to one of the CPU and the HWE in which a waiting time arises when the CPU and the HWE operate at the maximum clock frequencies, thus reducing power consumption.

PROBLEM TO BE SOLVED: To effectively suppress the power consumption of the whole system by positively generating inactive processors even in a state where the number of tasks is over that of processors. SOLUTION: In this information processing system, OS previously knows the resource request quantity of the processors 11 and 12 of the processing unit of each task including OS itself to centralize the group of tasks to the specific processor 11 within a range in which the resources of the processors 11 and 12 are not short (a range in which the sum of the request quantity of the processor resources is not over 100). Thereby, the other processor 12 is brought into an inactive state so that power source supply for the inactive processor is stopped or a clock frequency is lowered. Thereby the power consumption of the whole system is effectively suppressed. COPYRIGHT: (C)1997,JPO

PROBLEM TO BE SOLVED: To remove SO 3 in flue gas, without being accompanied by the sharp increase of device cost and running cost. SOLUTION: This device is provided with an SO 3 separator 10 which separates and removes SO 3 from the flue gas of a boiler 1 before treatment with a wet desulfurizer 7. The SO 3 separator is equipped with a shell and tube type of heat exchanger, and it cools the flue gas to the dew point of H 2 SO 4 gas or under by passing the flue gas on the shell side and boiler feedwater on the tube side. The SO 3 components in the flue gas react with the moisture in the flue gas and turn into H 2 SO 4 gas, and the generated H 2 SO 4 gas condenses and adheres to the surface of a tube. A part of the SO 3 components can be removed from within the flue gas by washing the liquid-form H 2 SO 4 adhering to the surface of the tube in water. Hereby, a wet electric dust collector 8 to be installed downstream of the wet desulfurizer can be downsized, and the device cost can be reduced as a whole. COPYRIGHT: (C)2003,JPO

Device for removing so3 from flue gas

An SO 3 separating and removing equipment (10) capable of lowering the density of SO 3 contained in flue gas and separating and removing SO 3 component from the flue gas at the inlet of a wet type desulfurization equipment (7) by installing a sodium carbonate feeding device (20) for feeding sodium carbonate to the flue gas at the outlet of a boiler (1), comprising a heat exchanger of shell and tube type, wherein the flue gas is passed through a shell side and boiler feed water is passed through the tube side to cool the flue gas to the dew point of H 2 SO 4 gas or below to react the SO 3 component contained in the flue gas with moisture contained in the flue gas according to the lowering of temperature so as to produce H 2 SO 4 gas which is condensed and adhered onto the surface of tubes, and the liquid H 2 SO 4 adhered onto the surface of the tubes is washed out by using water to remove the SO 3 component from the flue gas, whereby the consumed amount of sodium carbonate can be remarkably reduced, and a plant running cost can be prevented from increasing.

So3 separating and removing equipment for flue gas

PURPOSE:To travel smoothly by immediately increasing front wheel driving force to a large value when a rear wheel slips and to avoid wasteful consumption of engine output when the rear wheel is not slipping. CONSTITUTION:When a rear wheel 3 is not slipping, displacement of a variable displacement hydraulic pump 15 is controlled to bring delivery pressure thereof to a low value, and when the rear wheel 3 is slipping, the displacement of the variable displacement hydraulic pump 15 is controlled to bring the delivery pressure thereof to a high value. Front wheel driving force is made small when the rear wheel 3 is not slipping, and is made large when the rear wheel 3 is slipping.
