Title: Distributed processing method in distributed memory-type parallel computer and computer-readable recording medium
Inventor: INABA MASANOBU
IPC: G06F15/17
Filed: 2000-08-30
Abstract: PROBLEM TO BE SOLVED: To speed up a distributed processing in a distributed memory-type parallel computer. SOLUTION: A node 0 is set to be a master, and nodes 1 to 3 to be slaves in the nodes 0 to 3 constituting the distributed memory-type parallel computer. A processing is distributed and performed in the nodes 0 to 3. Initial data are transferred to the slave nodes 1 to 3 from the master node 0 and local calculation is performed in the respective nodes 0 to 3. When local calculation is terminated, the slave nodes 1 to 3 perform a test and set instruction to the communication register 41 of a network 4. Thus, the slave node which terminates local calculation earliest is decided to the master mode for result merging (2, for example). Then, the master node for result merging 2 collects the local calculation results of the other salve nodes 1 and 3 and merges them with a self-local calculation result. The master node 0 finally collects a merging result from the master node for result merging 2 and merges it with the self-local calculation result.

IPC: H02P7/282
Filed: 2000-08-31
Abstract: PROBLEM TO BE SOLVED: To quietly and quickly start an engine so that a vehicle is runnable as soon as an accelerator is operated in an economic run system for stopping the engine during stopping. SOLUTION: A starter motor comprises a compound coil 6 connected in parallel to a direct coil 5 for generating a field magnetic flux. The compound coil 6 is controlled by an ECU 11 through a compound control element 10. The ECU 11 minimizes the torque fluctuation of an engine by the ON-OFF of the compound coil 6 according to the fluctuation of engine load to minimize the noise caused by the rotating fluctuation of the engine 1. Since the output rotating speed of a starter 2 is increased, when the engine load is minimized, to continuously press the ring gear of the engine 1 by a pinion, the collision sound between the pinion and the ring gear can be eliminated.  Further, since the current carrying to the compound coil 6 is stopped in the end of the cracking of the engine 1 to quickly start up the engine 1 with unstable complete explosion, the time from starting to departure can be shortened.

Abstract: PROBLEM TO BE SOLVED: To provide an introducing air control device for a metallic oxide reducing furnace excellent in the stability as well as the response property of control and capable of continuing the operation of the same even upon abnormality of oxygen concentration.
