Title: Load balancing system for parallel processors
Inventor: NAKAJIMA HIROSHI
IPC: G06F15/16
Filed: 1990-02-08
Abstract: PURPOSE:To balance the load among unit processors by assigning a partial problem to a unit processor whose evaluation function determined by the distance from this unit processor to each unit processor and the load of each unit processor goes to minimum when the load is balanced. CONSTITUTION:When the load is balanced among all unit processors 5, a communication line determining circuit 20 assigns a partial problem to a unit processor PEi having a minimum evaluation function F(Di,j, Lj) which is determined by a distance Di,j between the unit processor PEi and an arbitrary processor PEj and a load Lj of the processor PEj and is a monotone nondecreasing function of the distance Di,j and the load Lj. Thus, the feature that the communication volume between unit processors is taken into consideration to balance the load among unit processor is kept in the assigning system, and the transfer direction of a packet which bears information to command the execution of the partial problem is determined with the simple circuit.

Title: Toothed transmission belt
Inventor: ARAKI JIYUNICHI
IPC: B29D29/08
Filed: 1984-02-17
Abstract: PURPOSE:To reduce a low frequency sound caused by variations of a load on a cam shaft of an internal combustion engine as well as improve heat resistance and durability by profitably employing a rubber material having higher complex modulus at a high sound and not oxidized by ozone. CONSTITUTION:A toothed belt 1 comprises an endless belt body 3 havig many engagement teeth on an inner peripheral surface thereof, a tensile body made of plural glass fiber stranded wires, etc., and wear-resistant protective body 5 with which the inner peripheral surface having the engagement teeth 2 is covered. The belt body 3 is made of vulcanized rubber formed by an acrylonitrile-conjugated diene copolymer to which rubber hydrogenated NBR corresponds which is for example yielded by hydrogenating 94% of double bonds in NBR. Since the hydrogenated NBR is hydrogenated for most part of the double bonds thereof to provide single bonds, it is difficult to be oxidized and deteriorated by ozone. In addition, the hydrogenated NBR has high complex modulus at the time of a high sound. Thus, a low frequency sound can be greatly reduced, which is caused by variations of a load on the cam shaft.
