  • Patent number: 8030947
    Abstract: Second and third ports of a network analyzer are individually connected via cables to predetermined connection points on a differential transmission circuit on an object to be measured. A differential cable is connected to the differential transmission circuit. An antenna for receiving an electromagnetic wave radiated from the differential cable is connected to a first port of the network analyzer via a first cable. The network analyzer measures a three-port S parameter of the first, second, and third ports and calculates common-mode and normal-mode components of noise radiated from the differential cable. As a result, the source of noise in an electronic apparatus can be determined, and common-mode noise and normal-mode noise can be separately measured.

  • Publication number: 20100163586
    Abstract: The present invention provides a stopper structure capable of preventing loosening of a shaft rod during use, and gas leakage which is likely to occur when the stopper structure is designed to allow gas to pass therethrough. The shaft rod 1 is adapted to be mounted in a mounting hole 2a of a refractory stopper 2, and formed to have an outer peripheral surface including a first tapered sub-surface 4a which increases in diameter toward an axially lower edge of the shaft rod. The mounting hole 2a of the refractory stopper 2 is formed to have an inner surface including a second tapered sub-surface 4b adapted to come into surface contact with the first tapered sub-surface 4a. The shaft rod 1 is adapted to be fastened to the refractory stopper so as to allow the first tapered sub-surface 4a to be brought into close surface contact with the second tapered sub-surface 4b.
