Title: Method for providing fault tolerance in computing system
Inventor: TSAI TIMOTHY
IPC: G06F3/048
Filed: 1999-06-16
Abstract: PROBLEM TO BE SOLVED: To detect a fault without correction of a program code by using separate controllers for controlling execution of each copy of a target program based on the information specified by a user. SOLUTION: When difference is detected in a value reported from a back end 28-1 on a remote machine by a front end 100 in a user machine, a back end with a value in a minority group is discriminated as a back end with error and the execution of the target program on a corresponding machine is stopped. For example, when the back end with error is defined as a back end 28-2, a check point is taken from the back end 28-1 among back ends without error, check point data are copied to the machine with the back end 28-2 with error and a new target program is started on the back end by using the data. The error is detected and corrected by such mechanism.

IPC: H02K11/02
Filed: 1999-06-17
Abstract: PROBLEM TO BE SOLVED: To prolong a service life and to realize high speed rotation by making the specific resistance of a brush material small on a minus side, large on a plus side, and inserting a capacitor in parallel with the power source. SOLUTION: A capacitor 11 is connected to a DC power output in parallel. A brush 8, connected to the plus side of DC power, is formed of a material whose specific resistance is large such as a carbon system and a brush 9 connected to a minus side is formed of a material, whose specific resistance is small, such as a metal graphite material. The resistance of the minus side brush 9 to cations is improved, arc discharge is reduced and abrasion of the brush can be reduced. Thus, a DC commutator motor for high speed rotation can be obtained. The pipe shapes of a plus side and a minus side are varied, so that the pipe cannot be inserted into the hole of another pipe. Consequently, quality troubles due to insertion errors can be prevented in advance.
