Abstract: A sealed kneading machine includes a kneading chamber to which a material to be kneaded is supplied, and a rotor disposed in the kneading chamber to be able to rotate about a rotor shaft. The rotor includes a plurality of kneading blades for kneading the material to be kneaded, and the length of all the kneading blades in the rotor shaft direction of each thereof is 45% or less of the total length of the rotor in the rotor shaft direction.

Abstract: Provided is a computer system in which power consumption of the system can be reduced and which can smoothly supply data for a request from a client and avoid increase in a failure rate. In the computer system, by maintaining a power activation threshold for activating a stopping server blade and load balance threshold for assigning the request to a server blade, a server blade whose power is activated but to which the request from the client is not assigned is previously arranged. Priorities of the server blades are maintained, and are periodically changed or are changed in accordance with operation information such as total operation time and the number of times of activation/stop. Further, by maintaining the power activation threshold and a power stop threshold, possibilities of the unbalance among the activated/stopped server blades and frequent control of the activation/stop only in a part of server blades are avoided.

Abstract: A load distribution system including an information table having information about a plurality of servers, a threshold holder having a threshold with respect to a processing state of requests to maintain service level of the plurality of servers, a server manager for monitoring and managing operational states of the plurality of servers, a transmission destination determiner for assigning the requests to a server having a higher priority until the processing state of the server reaches the threshold and after that assigning the requests to the server having a next higher priority; and a power controller for controlling powers of the plurality of servers according to processing states of the plurality of servers for the requests.
