    • [Object] To simply and accurately determine the position of an edge, the depth or the height of a flaw including a surface crack, a corroded portion near the surface layer of a thick specimen, and a minute damage.[Solving Means] An ultrasonic flaw detection method causes an ultrasonic wave 16 to be incident on a specimen 6 from an oblique direction, detects a diffracted wave 17 generated at an edge of a flaw 20 in the specimen 6 above the flaw, and determines the position of the edge of the flaw 20 from a front surface 13 of the specimen 6 using a triangular method from an entire beam path Wt of a component 18, which directly propagates above the flaw 20, of the diffracted wave, the entire beam path passing through the flaw from the position of incidence of the component 18, and an interval S between the position of incidence and the position of detection of the ultrasonic wave or from the difference (tt−ts) between the propagation time of a surface wave 15, to which the above relations reflect, to reception and the propagation time of the diffracted wave 18, which directly propagates above the flaw, to reception.

    • The present invention is to provide a gateway device which, when determining that a network device connected thereto is a web camera and receives a packet from the web camera, is able to automatically add a port of the gateway device connected with the network device to a VLAN designated by the gateway device and then add a specific group code to the packet to specify the VLAN, such that the gateway device can transmit the packet to the VLAN according to the specific group code. The gateway device is then able to automatically set transmission priority of the packet to a high priority, such that after the packet is transmitted out of the VLAN, the packet can be transmitted through a transmission channel with the high priority, so as to improve the convenience of using the web camera and assure the transmission priority of the packet in the VLAN.
    • 本发明是提供一种网关设备,当确定与其相连的网络设备是网络摄像机并且从网络摄像机接收到分组时,能够自动将与网络设备连接的网关设备的端口添加到 VLAN由网关设备指定,然后将特定的组码添加到数据包中以指定VLAN,使得网关设备可以根据特定的组代码将数据包传输到VLAN。 因此,网关设备能够自动将分组的传输优先级设置为高优先级,使得在从VLAN发送分组之后,可以通过高优先级的传输信道来传送分组,从而改善 方便使用网络摄像头,保证VLAN内的数据包的传输优先级。
