摘要： The invention relates to a welding torch for welding underwater and to a method of underwater welding using the welding torch. A high speed stream of water is directed from a nozzle on the welding torch obliquely onto a member or members to be welded to form a flared-out curtain of water. Gas is injected into the volume enclosed by the curtain of water to create a gaseous atmosphere and welding is carried out in the gaseous atmosphere.

摘要： An ETC (electronic toll collection) system includes an antenna having a predetermined directivity for providing a limited radio-communication service zone. A vehicle sensor operates for detecting a vehicle which reaches a predetermined position in the limited radio-communication service zone. A radio signal is transmitted via the antenna. A decision is made as to whether or not a radio response to the radio signal is received via the antenna. In cases where a radio response to the radio signal is received, it is judged that there is an ETC vehicle incoming. In cases where the vehicle sensor detects a vehicle while a radio response to the radio signal is not received, it is judged that there is a non-ETC vehicle incoming.
摘要翻译： ETC（电子收费）系统包括具有用于提供有限的无线电通信服务区的预定方向性的天线。车辆传感器用于检测在受限无线电通信服务区中到达预定位置的车辆。通过天线发送无线电信号。决定是否经由天线接收对无线电信号的无线电响应。在接收到对无线电信号的无线电响应的情况下，判断有ETC车辆进入。在没有接收到对无线电信号的无线电响应的情况下车辆传感器检测到车辆的情况下，判断为非ETC车辆进入。

摘要： A hydraulic blasting apparatus has an abrasive storage tank disposed operatively between an abrasive recovery tank and a hydraulic pressurized tank. The abrasive storage tank is provided with a first valve openable from the inside of the storage tank to the atmospheric pressure, and also with a second valve to open the connection between the storage tank and the recovery tank and with a third valve to open the connection between the storage tank and the pressurized tank. The pressure in the abrasive storage tank will become the same as the atmospheric pressure by opening the first valve. Next the first and second valve are closed, and after that the third valve is opened so as to drop the abrasive only into the pressurized abrasive tank for a recycle use.
摘要翻译：液压喷砂装置具有可操作地设置在磨料回收罐和液压加压罐之间的研磨储存罐。磨料储罐设置有可从储罐内部开启至大气压力的第一阀，并且还具有第二阀，用于打开储罐和回收罐之间的连接，并与第三阀打开连接在储罐和加压罐之间。研磨储罐中的压力将通过打开第一阀而与大气压力相同。接下来，关闭第一和第二阀，然后打开第三个阀，以将研磨剂落到加压的研磨罐中以进行再循环使用。
