  • Publication number: 20120011414
    Abstract: A network management system includes a management apparatus and a managed apparatus which is managed by the management apparatus via a network. The managed apparatus transmits trap information provided with a sequence number to the management apparatus and stores the trap information in a first storage unit. The management apparatus stores the received trap information in a second storage unit, and creates information indicating a missing sequence number and a sequence number of a last trap information received from the managed apparatus, and transmits the information to the corresponding managed apparatus. The managed apparatus determines whether trap information is to be retransmitted is present based on the trap information stored in the first storage unit and the information received from the management apparatus, and retransmits the trap information, based on the determination.

  • Publication number: 20080199313
    Abstract: Provided are a method of manufacturing a brazed rotor composed of a wheel and a shaft joined to the former by brazing, having a durability and a reliability which can be enhanced without increasing the manufacturing man hours, and a turbine rotor for an exhaust turbo-supercharger. The wheel having a disc portion formed at its outer periphery with blades, and a rod-like shaft are arranged in a furnace, being opposed to each other at their surfaces to be joined with a brazing solder being interposed therebetween, and infrared radiation is irradiated onto a side part of the wheel so as to heat the surfaces to be joined up to a temperature in a range from 1,000 to 1,080 deg. C. in order to melt the brazing solder, thereby the wheel and the shaft are joined by brazing to each other at their surfaces to be joined.
